Description

一种资源分配方法及相关设备 技术领域
本发明实施例涉及通信技术领域，具体涉及一种资源分配方法及相关设备。
背景技术
在移动通信系统中，每一基站可以提供一个或者多个小区，基站提供的小区边缘可能会与邻近基站提供的小区重叠，因此，位于小区边缘的用户设备(User Equipment，UE)(也称为边缘用户)在进行数据传输的时候可能会由于小区间信号的相互干扰而受到影响。
为了解决上述问题，现有技术是在边缘用户有数据传输需求的时候，处于不同地理位置的多个基站可以协同参与为边缘用户分配资源，以避免相邻小区的边缘用户之间相互干扰。但是，多个基站协同参与为边缘用户分配资源可能会在基站间产生大量的数据交换，从而增加了基站间X2接口的信令开销。
发明内容
本发明实施例公开了一种资源分配方法及相关设备，能够减小基站间X2接口的信令开销。
本发明实施例第一方面公开了一种资源分配方法，该方法包括：

第一网络设备根据该相邻小区的资源分配信息为第一UE分配资源，该资源具体为无线通信资源。
具体的，第一网络设备会结合相邻小区的资源分配信息，避免为第一UE 分配资源时与附近且连接其他网络设备的UE的资源发生冲突，从而避免干扰第一网络设备接收第一UE的上行数据或避免干扰位于第一UE所在服务小区的相邻小区的其他UE接收下行数据。
第一网络设备可以通过PC5接口或者Uu接口接收第一UE上报的该第一UE所在服务小区的相邻小区的资源分配信息，也可以通过PC5接口接收其他网络设备发送的第一UE所在服务小区的相邻小区的资源分配信息，从而可以根据相邻小区的资源分配信息为第一UE分配资源，以避免与位于该相邻小区的UE使用相同的资源，从而减小对相邻小区的干扰，或者为第一UE分配对该UE干扰较小的资源，以减少相邻小区对第一UE的干扰。通过这种方式，可以减少网络设备之间的X2接口的信令开销，并且在系统网络较为拥堵的情况下，还可以提高为UE分配资源的效率，从而能够在一定程度上减少UE传输数据的时延。
可选的，第一网络设备还可以通过接口接收第一UE上报的测量结果，并在该测量结果小于阈值的情况下，通过接口接收第一UE所在服务小区的相邻小区的资源分配信息。其中，该测量结果为第一UE对第一网络设备发送的参考信号进行信号测量的测量结果。
该测量结果可以包括但不限于信号与干扰加噪声比(Signal to Interference plus Noise Ratio，SINR)、参考信号接收功率(Reference Signal Receiving Power，RSRP)和参考信号接收功率(Reference Signal Receiving Power，RSRP)和参考信号接收质量(Signal Receiving Quality，RSRQ)中的至少一种。
通过这种方式，第一网络设备只有对位于网络边缘的UE分配资源时才会获取该UE所在服务小区的相邻小区的资源分配信息，可以提高对非网络边缘的UE分配资源的效率。
可选的，第一网络设备通过接口接收第一UE所在服务小区的相邻小区的资源分配信息的具体方式可以为：
通过第一接口发送请求消息，其中，该请求消息用于请求获取第一UE所在服务小区的相邻小区的资源分配信息；请求消息还可以携带第一UE所在服务小区的小区标识；
通过第一接口接收第二网络设备根据该请求消息反馈的该相邻小区的资 源分配信息，其中，该第二网络设备为该相邻小区所属的网络设备。
可选的，第一网络设备通过接口接收第一UE所在服务小区的相邻小区的资源分配信息的具体方式还可以为：
通过第一接口接收第二网络设备发送的该第二网络设备所管理的各小区的资源分配信息，并从该各小区的资源分配信息中确定第一UE所在服务小区的相邻小区的资源分配信息。
由网络设备通过PC5接口从其他网络设备获取UE所在服务小区的相邻小区的资源分配信息，这样可以减少X2接口的信令开销，并在系统网络较为拥堵的情况下，还可以提高为UE分配资源的效率，从而能够在一定程度上减少UE传输数据的时延。
可选的，第一网络设备通过接口接收第一UE所在服务小区的相邻小区的资源分配信息的具体方式还可以为：
通过接口接收第一UE上报的该第一UE所在服务小区的相邻小区的资源分配信息。
由UE搜集其所在服务小区的相邻小区的资源分配信息并上报给网络设备，这样可以减少网络设备之间X2接口的信令开销。
本发明实施例第二方面公开了一种网络设备，该网络设备可以包括收发模块和处理模块等，可以用于执行第一方面公开的资源分配方法。
本发明实施例第三方面公开了另一种网络设备，该网络设备可以包括收发器和处理器等，收发器对应于第二方面公开的网络设备的收发模块，处理器对应于第二方面公开的网络设备的处理模块，可以用于执行第一方面公开的资源分配方法。
本发明实施例第四方面公开了另一种资源分配方法，该方法包括：
第一UE接收该第一UE所在服务小区的相邻小区的资源分配信息，其中，该相邻小区所属的网络设备与第一UE所连接的第一网络设备不同；
第一UE通过接口将该相邻小区的资源分配信息上报给第一网络设备，其中，该相邻小区的资源分配信息用于第一网络设备为第一UE分配资源，接口包括第一接口或第二接口，第一接口为利用UE到UE通信技术进行通信的接口，如PC5接口、蓝牙配对的设备之间的接口、Wi-Fi连接的设备之间的接口等，第 二接口为利用UE到网络设备通信技术进行通信的接口，如Uu接口。
具体的，第一网络设备在接收到第一UE上报的相邻小区的资源分配信息后，会结合相邻小区的资源分配信息，避免为第一UE分配资源时与附近且连接其他网络设备的UE的资源发生冲突，从而避免干扰第一网络设备接收第一UE的上行数据或避免干扰位于第一UE所在服务小区的相邻小区的其他UE接收下行数据。
由UE搜集其所在服务小区的相邻小区的资源分配信息并上报给网络设备，这样可以减少网络设备之间X2接口的信令开销。
可选的，第一UE在接收其所在服务小区的相邻小区的资源分配信息后，还可以对第一网络设备发送的参考信号进行信号测量，得到第一测量结果，并判断第一测量结果是否小于第一阈值，如果第一测量结果小于第一阈值，再通过接口将该相邻小区的资源分配信息上报给第一网络设备。
通过这种方式，第一UE只有在位于第一网络设备的网络边缘的情况下，才会将获取到的第一UE所在服务小区的相邻小区的资源分配信息上报给第一网络设备，以请求第一网络设备为其分配资源，这样可以提高网络设备为网络边缘的UE分配资源的效率。
可选的，第一UE接收第一UE所在服务小区的相邻小区的资源分配信息的具体方式可以为：
通过第一接口接收至少一个第二UE发送的该第二UE的资源占用信息，其中，该资源占用信息为该第二UE所连接的网络设备为第二UE分配的资源的信息，该资源占用信息携带第二UE所在服务小区的小区标识，第二UE所在服务小区为第一UE所在服务小区的相邻小区，且第二UE所连接的网络设备与第一网络设备不为同一网络设备；
根据该小区标识从该至少一个第二UE发送的第二UE的资源占用信息中确定携带有相同小区标识的资源占用信息，并根据该携带有相同小区标识的资源占用信息确定该相同小区标识所标记的小区的资源分配信息。
各个UE可以广播自己的资源占用信息，第一UE在接收到相邻小区中各UE广播的资源占用信息后，可以根据资源占用信息携带的小区标识确定出各个相邻小区的资源分配信息，然后再将得到的资源分配信息上报给第一网络设 备，这样可以避免网络设备之间通过X2接口交互资源分配信息，从而可以减少X2接口的信令开销。
可选的，第一UE还可以在通过第一接口接收至少一个第二UE发送的所述第二UE的资源占用信息之前，通过第一接口发送第一请求消息，其中，该第一请求消息用于请求获取第一UE所在服务小区的相邻小区的UE的资源占用信息。该第一请求消息携带第一UE所在服务小区的小区标识。
第一UE可以向附近的UE发送请求，以获取相邻小区中各UE的资源占用信息，从而得到相邻小区的资源分配信息，然后再将得到的资源分配信息上报给第一网络设备，这样可以避免网络设备之间通过X2接口交互资源分配信息，从而可以减少X2接口的信令开销。
可选的，第一UE接收第一UE所在服务小区的相邻小区的资源分配信息的具体方式还可以为：
通过第一接口向第二网络设备发送第二请求消息，其中，该第二网络设备为第一UE所在服务小区的相邻小区所属的网络设备，第二请求消息用于请求获取该相邻小区的资源分配信息；
通过第一接口接收第二网络设备根据第二请求消息发送的该相邻小区的资源分配信息。该第三请求消息携带第一UE所在服务小区的小区标识。
第一UE可以通过PC5接口向相邻小区所属的网络设备发送请求，以获取相邻小区的资源分配信息，这样可以避免网络设备之间通过X2接口交互资源分配信息，从而可以减少X2接口的信令开销。
可选的，第一UE接收第一UE所在服务小区的相邻小区的资源分配信息的具体方式还可以为：
通过第一接口或者第二接口接收第二网络设备发送的第二网络设备所管理的各小区的资源分配信息，并从该各小区的资源分配信息中确定UE所在服务小区的相邻小区的资源分配信息，第二网络设备为该相邻小区所属的网络设备。第二网络设备发送的其管理的各小区的资源分配信息中携带对应小区的小区标识。
网络设备可以通过第一接口或者第二接口向UE广播其所管理的各小区的资源分配信息，那么第一UE在接收到各小区的资源分配信息后，可以从中确 定出其所在服务小区的相邻小区的资源分配信息，并将其上报给第一网络设备，这样可以避免网络设备之间通过X2接口交互资源分配信息，从而可以减少X2接口的信令开销。
具体的，第一UE根据该小区标识从该至少一个第二UE发送的第二UE的资源占用信息中确定携带有相同小区标识的资源占用信息的具体方式可以为：
在资源占用信息还携带第二测量结果的情况下，根据小区标识从第二测量结果小于第二阈值的该至少一个第二UE发送的第二UE的资源占用信息中确定携带有相同小区标识的资源占用信息，其中，第二测量结果为第二UE对第二UE所连接的网络设备发送的参考信号进行信号测量的测量结果。
第一UE通过这种方式可以确定出处于相邻小区边缘的UE的资源占用信息，并且由于第一UE能够接收到这些UE发送的资源占用信息，所以可以确定这些UE处理相邻小区的边缘，同时距离第一UE较近。一般地，处于小区覆盖边缘的UE使用较大的功率进行上行发送，对邻区干扰较大，同时基站向边缘UE发送下行时也会使用较大功率，对邻区边缘UE干扰较大。如果第一UE将这些UE的资源占用信息上报给第一网络设备，第一网络设备在为第一UE分配资源时，可以避免与这些UE的占用资源发生冲突，进而减少对第一UE以及这些UE的干扰。
具体的，第一UE根据该小区标识从该至少一个第二UE发送的第二UE的资源占用信息中确定携带有相同小区标识的资源占用信息的具体方式还可以为：
对第二UE发送的参考信号进行信号测量，得到第三测量结果，并根据该小区标识从第三测量结果大于第三阈值的该至少一个第二UE发送的第二UE的资源占用信息中确定携带有相同小区标识的资源占用信息。
第一UE通过这种方式可以确定出距离第一UE较近的UE，第一UE根据距离较近的UE的资源占用信息来确定相邻小区的资源分配信息，可以提高获取相邻小区的对第一UE存在干扰隐患的资源分配信息的精确度，从而使得第一网络设备为第一UE分配的资源时能够更加有效的避免对位于相邻小区覆盖边缘的UE的数据传输产生影响，或者避免第一UE受位于相邻小区覆盖边缘的UE的影响。
本发明实施例第五方面公开了一种用户设备，该用户设备可以包括收发模 块和处理模块等，可以用于执行第四方面公开的资源分配方法。
本发明实施例第六方面公开了另一种用户设备，该用户设备可以包括收发器和处理器等，收发器对应于第五方面公开的用户设备的收发模块，处理器对应于第五方面公开的用户设备的处理模块，可以用于执行第四方面公开的资源分配方法。
本发明实施例第七方面公开了又一种资源分配方法，该方法包括：
第二UE通过接口接收第一UE发送的请求消息，其中，该请求消息用于请求获取第一UE所在服务小区的相邻小区的UE的资源占用信息，该接口为利用UE到UE通信技术进行通信的接口，如PC5接口、蓝牙配对的设备之间的接口、Wi-Fi连接的设备之间的接口等，该请求消息可以包括第一UE所在服务小区的小区标识，以及第一UE所连接的第一网络设备的标识；
第二UE根据该小区标识确定第二UE所在服务小区为第一UE所在服务小区的相邻小区，且根据第一网络设备的标识确定第二UE所连接的网络设备与网络设备不同的情况下，通过接口将第二UE的资源占用信息发送给第一UE。
相邻小区的UE在接收到第一UE发送的获取相邻小区的UE的资源占用信息的请求消息后，相邻小区的UE通过PC5接口将其资源占用信息发送给第一UE，第一UE从而根据该资源占用信息确定相邻小区的资源分配信息，以便于第一UE所连接的网络设备可以根据相邻小区的资源分配信息为第一UE分配的资源能够更加有效的避免对该相邻小区的UE的数据传输产生影响，或者避免受该相邻小区的UE的影响。
可选的，第二UE在接收到请求消息后，还可以对第二UE所连接的网络设备发送的参考信号进行信号测量，得到第一测量结果，并在第一测量结果小于第一阈值的情况下，通过接口将第二UE的资源占用信息发送给第一UE。
通过这种方式，第二UE在接收到第一UE发送的请求消息后，只有在确定出自己处于网络覆盖边缘的时候才会将其资源占用信息发送给第一UE，从而可以提高第一UE获取相邻小区对第一UE存在干扰隐患的资源分配信息的精确度，使得第一UE所连接的网络设备为第一UE分配的资源能够更加有效的避免对位于相邻小区覆盖边缘的UE的数据传输产生影响，或者避免受位于相邻小区覆盖边缘的UE的影响。
可选的，第二UE通过接口将第二UE的资源占用信息发送给第一UE的具体方式可以为：
在请求消息还包括第一UE对第一UE所连接的网络设备发送的参考信号进行信号测量的第二测量结果，且第二测量结果小于第二阈值的情况下，通过接口将第二UE的资源占用信息发送给第一UE。
第二UE在接收到请求消息时，可以判断第一UE是否处于第一所连接的网络设备的网络覆盖边缘，如果处于第一所连接的网络设备的网络覆盖边缘，才会将其资源占用信息发送给第一UE，从而可以避免将其资源占用信息发送给第一网络设备的非网络覆盖边缘的UE，从而可以避免不必要信息的发送，减少第一接口上的信令开销。
本发明实施例第八方面公开了又一种用户设备，该用户设备可以包括收发模块和处理模块等，可以用于执行第七方面公开的资源分配方法。
本发明实施例第九方面公开了又一种用户设备，该用户设备可以包括收发器和处理器等，收发器对应于第八方面公开的用户设备的收发模块，处理器对应于第八方面公开的用户设备的处理模块，可以用于执行第七方面公开的资源分配方法。
本发明实施例第十方面还公开了一种资源分配系统，该系统可以包括上面所描述的网络设备和用户设备。在该系统中，第一网络设备可以通过PC5接口或者Uu接口接收第一UE上报的该第一UE所在服务小区的相邻小区的资源分配信息，也可以通过PC5接口接收其他网络设备发送的第一UE所在服务小区的相邻小区的资源分配信息，从而可以根据相邻小区的资源分配信息为第一UE分配资源，以避免与位于该相邻小区的UE使用相同的资源，从而减小对相邻小区的干扰，或者为第一UE分配对该UE干扰较小的资源，以减少相邻小区对第一UE的干扰。通过这种方式，可以减少网络设备之间的X2接口的信令开销，并且在系统网络较为拥堵的情况下，还可以提高为UE分配资源的效率，从而能够在一定程度上减少UE传输数据的时延。
本发明实施例第十一方面公开了又一种资源分配方法，该方法包括：
UE根据待传输D2D数据的第一业务类型建立与该第一业务类型对应的逻辑信道，并从资源分配信息所分配的资源中确定用于承载该逻辑信道上的待传 输D2D数据的资源。
其中，第一业务类型包括车联网类业务，车联网类业务可以指V2X类业务。与第一业务类型对应的逻辑信道可以理解为：为V2X类业务的D2D数据建立专用的逻辑信道；或者建立D2D的逻辑信道，即沿用为PS类业务的D2D数据建立逻辑信道的过程来建立逻辑信道，但需要标记上哪些逻辑信道用于承载V2X类业务的D2D数据，哪些逻辑信道用于承载PS类业务的D2D数据。具体可以是，UE在为待传输D2D数据建立逻辑信道时，可以在该逻辑信道上标记该第一业务类型的标识。
具体的，该资源分配信息所分配的资源可以是用于承载D2D数据的资源，该资源分配信息可以包括载波信息，如载波频率、载波频率上可进行的业务、用于承载D2D数据的PRB信息等，本发明实施例不做限定。UE的资源分配信息中还可以包括对应资源所承载数据的业务类型，那么UE就可以根据业务类型从承载D2D数据的资源中选取用于承载第一业务类型的D2D数据的资源，这样UE就可以在该资源上发送待传输D2D数据。
可选的，UE从资源分配信息所分配的资源中确定用于承载该逻辑信道上的该待传输D2D数据的资源之前，可以先获取用于承载D2D数据的资源的资源分配信息。其中，该资源分配信息可以包括该用于承载D2D数据的资源的数据承载方式。
那么UE从资源分配信息所分配的资源中确定用于承载该逻辑信道上的该待传输D2D数据的资源的具体方式就可以为：
根据该数据承载方式，从该用于承载D2D数据的资源中确定用于承载该逻辑信道上的待传输D2D数据的资源。
需要说明的是，用于承载D2D数据的资源的数据承载方式(可以称为资源分配信息所分配资源的用途)有两种，一种是独享资源方式，另一种是共享资源方式。其中，独享资源方式，即不同业务类型的D2D数据使用不同的资源发送；共享资源方式，即不同业务类型的D2D数据使用相同的资源发送。那么UE在确定出用于承载D2D数据的资源的数据承载方式之后，就可以根据具体的数据承载方式从资源分配信息所分配的资源中确定用于承载该逻辑信道上的该待传输D2D数据的资源。
可选的，当该数据承载方式为独享资源方式时，该资源分配信息还可以包括用于承载D2D数据的资源所承载的D2D数据的第二业务类型。那么UE可以将用于承载D2D数据的资源中所承载的D2D数据的第二业务类型与第一业务类型一致的资源确定为用于承载该逻辑信道上的待传输D2D数据的资源。
可选的，UE获取用于承载D2D数据的资源的资源分配信息的具体方式可以为：
从预配置的资源中获取用于承载D2D数据的资源的资源分配信息；
或者，
接收网络设备发送的用于承载D2D数据的资源的资源分配信息。
通过这种方式，UE可以根据其生成的D2D数据的业务类型标记逻辑信道，然后通过区分来自网络设备或自身预配置的资源分配信息所分配资源的数据承载方式，在发送D2D数据过程中可以独享资源，从而能够提高资源使用的灵活性，并能够减少接收端接收数据的功耗。
本发明实施例第十二方面公开了又一种用户设备，该用户设备可以包括收发模块和处理模块等，可以用于执行第十一方面公开的资源分配方法。
本发明实施例第十三方面公开了又一种用户设备，该用户设备可以包括收发器和处理器等，收发器对应于第十二方面公开的用户设备的收发模块，处理器对应于第十二方面公开的用户设备的处理模块，可以用于执行第十一方面公开的资源分配方法。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例公开了一种资源分配方法及相关设备，能够减小基站间X2接口的信令开销。以下分别进行详细说明。
为了更好的理解本发明实施例公开的一种资源分配方法及相关设备，下面先对本发明实施例适用的通信网络架构进行描述。请参阅图1，图1是本发明实施例公开的一种通信网络的架构示意图。在图1所示的网络架构中，包括第一网络设备、第二网络设备、UE1和UE2。本申请中，网络设备可以包括但不限于演进型基站(evolved Node B，eNB)、无线网络控制器、基站控制器、接入点(Access Point，AP)等，用户设备UE可以包括各种具有无线通信功 能的手持设备、车载设备、可穿戴设备、计算机设备或连接到无线调制解调器的其他处理设备，以及各种形式的用户设备、移动台(Mobile Station，MS)、终端(terminal)、终端设备(Terminal Equipment)等等，为方便描述，本申请中，上面提到的设备统称为用户设备或UE。第一网络设备与第二网络设备之间的接口可以包括但不限于X2接口和PC5接口，第二网络设备对应的小区可以与第一网络设备对应的小区处于水平方向上的相邻(如两个相邻的eNB，或者eNB的网络覆盖范围内两个相邻的小小区)，也可以与第一网络设备对应的小区处于重叠的覆盖(如在第一网络设备的网络覆盖范围内设置小小区)。当网络设备为eNB时，UE1处于第一网络设备的网络覆盖边缘，可以通过Uu接口与第一网络设备进行通信，第一网络设备可以为UE1分配无线通信资源(以下简称资源)，UE2处于第二网络设备的网络覆盖边缘，且位于UE1附近，可以通过Uu接口与第二网络设备进行通信；UE1还可以通过PC5接口与第一网络设备进行通信，UE2还可以通过PC5接口与第二网络设备进行通信；UE1与UE2之间通过PC5接口进行通信。UE1可以通过PC5接口向第二网络设备发送数据或者接收第二网络设备发送的数据，也可以通过Uu接口接收第二网络设备广播的数据。
进一步的，第一网络设备和第二网络设备还可以协同为UE1提供下行数据传输服务，例如，第一网络设备和第二网络设备在相同的资源上向UE1发送数据，UE1向第一网络设备反馈是否正确接收到数据和信道状态信息(Channel State Information，CSI)报告，并通过UE2向第二网络设备反馈是否正确接收到数据和CSI报告，CSI报告包括信道质量指示(Channel Quality Indication，CQI)，预编码矩阵指示(Precoding Matrix Indication，PMI)、秩指示(Rank Indication，RI)等，第二网络设备会根据UE1反馈的信息调整向UE1发送数据的资源、功率，或者在发送数据失败确定是否重传等。
通过实施图1所示的网络架构，UE1在有上行数据传输的情况下，将相邻小区的上行资源分配信息上报给第一网络设备，或者第一网络设备在UE1有下行数据的情况下，通过PC5接口获取UE1所在服务小区的相邻小区的下行资源分配信息，第一网络设备从而可以根据相邻小区的资源分配信息为UE1分配资源。第二网络设备和第一网络设备协同为UE1提供下行数据传输服务时，UE1通过UE2将反馈信息发送给第二网络设备，这样可以减少第一网络 设备与第二网络设备之间的信息交互。通过这种方式网络设备可以通过PC5接口或者Uu接口获取UE的相关信息，从而可以减少基站间X2接口的信令开销。
基于图1所示的网络架构，本发明实施例公开了一种资源分配方法。请参阅图2，图2是本发明实施例公开的一种资源分配方法的流程示意图。其中，图2所描述的方法可以应用于网络设备。如图2所示，该资源分配方法可以包括以下步骤：
201、第一网络设备通过接口接收第一UE所在服务小区的相邻小区的资源分配信息。
本发明实施例中，第一UE与第一网络设备建立有通信连接。该接口可以包括第一接口或者第二接口，第一接口为利用UE到UE通信技术进行通信的接口，可以为PC5接口、蓝牙配对的设备之间的接口或者Wi-Fi连接的设备之间的接口，第二接口为利用UE到网络设备通信技术进行通信的接口，可以为Uu接口。第一UE所在服务小区的相邻小区是指该小区与第一UE所在服务小区相邻，且该小区所属的网络设备和第一网络设备不为同一网络设备。相邻小区的资源分配信息为该相邻小区所服务的部分或全部UE的资源占用信息的集合，UE的资源占用信息是指网络设备为该UE所分配的资源的相关信息，例如，该UE在哪些物理资源块(Physical Resource Block，PRB)上有数据传输，UE在哪些时间上有数据传输等。其中，网络设备为该UE所分配的资源可以包括频域资源和时间资源中的至少一种，且该资源包括上行资源和下行资源。
本发明实施例中，第一网络设备可以通过第一接口接收其他网络设备发送的第一UE所在服务小区的相邻小区的资源分配信息，也可以通过第一接口或者第二接口接收第一UE上报的该相邻小区的资源分配信息，本发明实施例不做限定。
需要说明的是，第一网络设备在需要为第一UE分配下行资源的情况下可以接收第一UE发送的或者其他网络设备发送的该第一UE所在服务小区的相邻小区的下行资源的资源分配信息；第一UE在需要第一网络设备为其分配上行资源的情况下，可以搜集相邻小区的上行资源分配信息，从而上报给第一网 络设备。
202、第一网络设备根据该相邻小区的资源分配信息为第一UE分配资源。
本发明实施例中，第一网络设备在接收到第一UE所在服务小区的相邻小区的资源分配信息后，可以根据该相邻小区的资源分配信息为第一UE分配资源。
具体的，第一网络设备会结合相邻小区的资源分配信息，避免为第一UE分配资源时与附近且连接其他网络设备的UE的资源发生冲突，从而避免干扰第一网络设备接收第一UE的上行数据或避免干扰位于第一UE所在服务小区的相邻小区的其他UE接收下行数据。
可见，在图2所描述的方法中，第一网络设备可以通过PC5接口或者Uu接口接收第一UE上报的该第一UE所在服务小区的相邻小区的资源分配信息，也可以通过PC5接口接收其他网络设备发送的第一UE所在服务小区的相邻小区的资源分配信息，从而可以根据相邻小区的资源分配信息为第一UE分配资源，以避免与位于该相邻小区的UE使用相同的资源，从而减小对相邻小区的干扰，或者为第一UE分配对该UE干扰较小的资源，以减少相邻小区对第一UE的干扰。通过这种方式，可以减少网络设备之间的X2接口的信令开销，并且在系统网络较为拥堵的情况下，还可以提高为UE分配资源的效率，从而能够在一定程度上减少UE传输数据的时延。
基于图1所示的网络架构，本发明实施例公开了另一种资源分配方法。请参阅图3，图3是本发明实施例公开的另一种资源分配方法的流程示意图。如图3所示，该资源分配方法可以包括以下步骤：
301、第一UE通过接口向第一网络设备发送第一测量结果。
本发明实施例中，第一UE通过第一接口和第二接口与第一网络设备建立连接。第一UE在接收到第二网络设备发送的参考信号时，可以对该参考信号进行信号测量，得到第一测量结果，并将该第一测量结果通过接口(第一接口或者第二接口)发送给第一网络设备。
其中，该第一测量结果可以包括但不限于SINR、RSRP和RSRQ中的至少 一种。
进一步的，如果第一UE有上行数据的传输需求，可以向第一网络设备发送资源分配请求消息，该请求消息可以包括缓存状态报告(Buffer Status Report,BSR)，该请求消息可以是单独发送给第一网络设备的，也可以是和第一测量结果一起发送给第一网络设备的，本发明实施例不做限定。
302、第一网络设备通过接口接收该第一测量结果。
303、第一网络设备在该第一测量结果小于第一阈值的情况下，通过第一接口发送请求消息。
本发明实施例中，第一网络设备在接收到第一UE发送的第一测量结果后，可以检测该第一测量结果是否小于第一阈值，该第一阈值为判断第一UE是否处于第一网络设备的网络覆盖边缘的临界值。第一网络设备如果接收到第一UE发送的资源分配请求，可以在判断出第一测量结果小于第一阈值的情况下，通过第一接口广播或者向其他网络设备发送请求消息，该请求消息用于请求获取第一UE所在服务小区的相邻小区的资源分配信息。第一网络设备如果检测到存在UE1的下行数据，也可以在判断出第一测量结果小于第一阈值的情况下，通过第一接口广播或者向其他网络设备发送请求消息。
通过这种方式，第一网络设备可以确定处于第一网络设备所管理的小区边缘的UE，考虑到当为这些UE分配上行资源时，由于这些UE处于小区边缘，需要使用较大的发发射功率来发送上行数据，这样可能会干扰到相邻网络设备接收相邻小区的UE的上行数据。同时，在为这些UE分配下行资源时，由于这些UE处于小区边缘，第一网络设备需要使用较大功率发送下行数据，这样可能干扰到相邻小区的UE接收下行数据。
进一步的，该请求消息可以携带有第一网络设备的标识以及第一UE所在服务小区的标识。
304、第二网络设备接收第一请求消息，并根据该请求消息确定该第一UE所在服务小区的相邻小区。
本发明实施例中，第二网络设备可以指一个网络设备，也可以指多个网络设备，本发明实施例不做限定。第二网络设备在接收到第一请求消息后，可以根据该第一请求消息携带的第一UE所在服务小区的小区标识从第二网络设备 所管理的各小区中确定是否存在第一UE所在服务小区的相邻小区，如果存在，再进一步确定该相邻小区的资源分配信息。
需要说明的是，该相邻小区可以为一个，也可以为多个，该相邻小区的资源分配信息可以包括该相邻小区中的所有UE所占用资源的信息，也可以只包括位于该相邻小区的网络覆盖边缘，且靠近第一UE所在服务小区的UE所占用资源的信息，本发明实施例不做限定。
305、第二网络设备通过第一接口向第一网络设备发送该相邻小区的资源分配信息。
本发明实施例中，第二网络设备在确定出相邻小区的资源分配信息后，可以通过第一接口向第一网络设备发送该相邻小区的资源分配信息，该资源分配信息携带有该相邻小区的小区标识。
可选的，第二网络设备还可以通过第一接口广播或者向第一网络设备发送该第二网络设备所管理的各小区的资源分配信息，各小区的资源分配信息中也携带有各个小区的小区标识。那么第一网络设备在接收到第二网络设备发送的各小区的资源分配信息后，根据各个小区的小区标识可以从各小区的资源信息中确定出第一UE所在服务小区的相邻小区的资源分配信息。
306、第一网络设备通过第一接口接收该相邻小区的资源分配信息，并根据该相邻小区的资源分配信息为第一UE分配资源。
可见，在图3所描述的方法中，第一网络设备可以通过第一接口向第二网络设备发送请求消息以请求获取第一UE所在服务小区的相邻小区的资源分配信息，从而接收第二网络设备根据该请求消息发送的相邻小区的资源分配信息；第二网络设备也可以通过第一接口直接向第一网络设备发送其管理的各小区的资源分配信息，第一网络设备从各小区的资源分配信息中筛选出第一UE所在服务小区的相邻小区的资源分配信息。通过这种方式可以避免网络设备在为UE分配资源的时候通过X2接口向其他网络设备获取相邻小区的资源分配信息，从而可以减少网络设备之间X2接口的信令开销，并在系统网络拥堵的情况下，可以提高资源分配信息的获取效率。
基于图1所示的网络架构，本发明实施例公开了又一种资源分配方法。请 参阅图4，图4是本发明实施例公开的又一种资源分配方法的流程示意图。如图4所示，该资源分配方法可以包括以下步骤：
401、第一UE通过第一接口发送第一请求消息。
本发明实施例中，第一UE在有上行数据需要发送的时候，要向第一UE所连接的第一网络设备请求上行资源，即向第一网络设备发送BSR，该BSR中包括了第一UE上行数据的大小等相关信息。第一UE在向第一网络设备发送BSR之前，可以先通过第一接口广播或者向附近的UE发送第一请求消息，该第一请求消息可以携带有第一UE所在服务小区的小区标识和第一UE所连接的第一网络设备的标识，用于请求获取第一UE所在服务小区的相邻小区的UE的资源占用信息。
可选的，第一网络设备还可以向第一UE发送获取第一UE所在服务小区的相邻小区的资源分配信息的请求消息，第一UE在接收到该请求消息后通过第一接口发送第一请求消息。可选的，第一网络设备向第一UE发送上述请求消息的触发条件可以为上述实施例中第一网络设备向第二网络设备发送资源分配信息请求信息的触发条件。
402、第二UE通过第一接口接收该第一请求消息，并确定第二UE所在服务小区为第一UE所在服务小区的相邻小区，且第二UE所连接的网络设备与第一UE所连接的第一网络设备不同。
本发明实施例中，假设第二UE通过第一接口接收到第一UE发送的第一请求消息，那么第二UE在接收到第一请求消息后，可以根据第一请求消息携带的小区标识确定第二UE所在服务小区是否为第一UE所在服务小区的相邻小区，并根据携带的第一网络设备的标识判断第二UE所连接的网络设备与第一网络设备是否为同一网络设备。
如果第二UE确定第二UE所在服务小区为第一UE所在服务小区的相邻小区，且第二UE所连接的网络设备与第一网络设备不同，第二UE会通过第一接口向第一UE发送该第二UE的资源占用信息；如果第二UE确定第二UE所在服务小区与第一UE所在服务小区为同一小区，或者第二UE所连接的网络设备与第一网络设备为同一网络设备，那么第二UE可以忽略第一请求消息。
403、第二UE通过第一接口向第一UE发送该第二UE的资源占用信息。
可选的，第二UE在确定出第二UE所在服务小区为第一UE所在服务小区的相邻小区，且第二UE所连接的网络设备与第一网络设备不同的情况下，还可以对第二UE所连接的网络设备发送的参考信号进行信号测量，得到第二测量结果，如果判断出第二测量结果小于第二阈值，第二UE才通过第一接口向第一UE发送该第二UE的资源占用信息。
需要说明的是，第二阈值为判断第二UE是否处于第二UE所连接的网络设备的网络覆盖边缘的临界值，可以与第一阈值相同，也可以不同。第二阈值由第二UE所连接的网络设备配置并发送给第二UE。也就是说，第二UE在确定出第二UE所在服务小区为第一UE所在服务小区的相邻小区，且第二UE所连接的网络设备与第一网络设备不同的情况下，会进一步判断自己是否处于其连接的网络设备的网络覆盖边缘。
可选的，第一UE发送的第一请求消息还可以携带第一UE的第一测量结果，第二UE在接收到第一请求消息后，可以先判断第一测量结果是否小于第一阈值。该第一阈值可以是第一网络设备配置并发送给第二UE的，本发明实施例不做限定。如果第一测量结果小于第一阈值，则表明第一UE位于第一网络设备的网络覆盖边缘，那么第二UE才会将其资源占用信息通过第一接口发送给第一UE。
404、第一UE通过第一接口接收至少一个第二UE发送的资源占用信息，并根据该至少一个第二UE发送的资源占用信息所携带的小区标识从该资源占用信息中确定携带有相同小区标识的资源占用信息。
本发明实施例中，第一UE通过第一接口可以接收到多个第二UE发送的该第二UE的资源占用信息，每个资源占用信息携带各自的小区标识，那么第一UE可以根据小区标识将具有相同小区标识的资源占用信息进行归类，得到携带有相同小区标识的资源占用信息。
举例来说，假设第一UE接收到5个第二UE发送的各自的资源占用信息a、b、c、d和e，资源占用信息a、b、c、d和e各自携带的小区标识分别为A、B、B、C和A，那么第一UE在接收到这些资源占用信息后，就可以分别确定出携带有小区标识A的资源占用信息为a和e，携带有小区标识B的资源占用信息为b和c，携带有小区标识C的资源占用信息为d。
可选的，该资源占用信息还可以携带有第二测量结果，第二测量结果为第二UE对第二UE所连接的网络设备发送的参考信号进行信号测量的测量结果。那么第一UE根据该资源占用信息所携带的小区标识从该资源占用信息中确定携带有相同小区标识的第一资源占用信息的具体方式可以为：第一UE在接收到第二UE发送的资源占用信息后，可以先判断第二测量结果是否小于第二阈值，如果小于，再根据小区标识从第二测量结果小于第二阈值的资源占用信息中确定携带有相同小区标识的资源占用信息。其中，第二阈值可以是第二UE所连接的网络设备配置并发送给第一UE的。
如果第二测量结果小于第二阈值，就表明第二UE位于其连接的网络设备的网络覆盖边缘，也可以在一定程度上表明第二UE的上下行数据传输会干扰到第一UE的上下行数据传输。第一UE发送的相邻小区的资源分配信息就可以理解为由相邻小区中位于小区边缘的UE的资源占用信息组成，那么第一网络设备在为第一UE分配资源的时候，能够更加有效的避免对相邻小区的干扰或者被相邻小区干扰。
可选的，第一UE在接收到第二UE发送的资源占用信息后，还可以对第二UE发送的参考信号进行测量，得到第三测量结果，该第三测量结果可以包括但不限于测行参考信号接收功率(Sidelink RSRP，S-RSRP)和侧行发现信号的参考信号接收功率(Sidelink Discovery RSRP，SD-RSRP)。如果第三测量结果大于第三阈值，可以表明第一UE与第二UE距离较近，如果小于，则距离较远，那么第一UE就可以根据小区标识从第三测量结果大于第三阈值的该至少一个第二UE发送的资源占用信息中确定出携带有相同小区标识的资源占用信息。第一UE发送的相邻小区的资源分配信息就可以理解为由相邻小区中靠近第一UE的其他UE的资源占用信息组成，那么第一网络设备在为第一UE分配资源的时候，能够更加有效的避免对相邻小区的干扰或者被相邻小区干扰。
需要说明的是，在第一接口如PC5接口上通信的UE可以使用各自连接的网络设备分配的资源发送数据，网络设备之间需要交互PC5接口上的资源，以便配置UE接收数据。或者，第一UE使用相邻小区所连接的网络设备广播的资源，这样网络设备之间则可以不交互这些资源信息。或者，所有的网络设备为UE的PC5接口分配的资源均相同。或者，UE之间接口上的资源可以使用非授权的 频谱信息，例如蓝牙和Wi-Fi。
405、第一UE根据该携带有相同小区标识的资源占用信息确定该相同小区标识所标记的小区的资源分配信息。
本发明实施例中，第一UE可以根据步骤404所确定的携带有相同小区标识的资源占用信息确定该相同小区标识所标记的小区的资源分配信息，即携带有某一小区标识的资源占用信息组成该小区标识所标记的小区的资源分配信息。
可选的，第二UE还可以主动发送自己的资源占用信息，如在网络设备的控制下周期性的广播第二UE的资源占用信息，该资源占用信息可以携带第二UE所在服务小区的小区标识，第一UE在接收到第二UE发送的资源占用信息后，可以根据小区标识筛选出位于第一UE所在服务小区的相邻小区的第二UE的资源占用信息；该资源占用信息还可以携带第二UE对第二UE所连接的网络设备发送的参考信号进行信号测量的测量结果，这样第一UE可以根据测量结果筛选出位于相邻小区覆盖边缘的第二UE的资源占用信息。第一UE从而可以根据小区标识和第二UE的资源占用信息确定出各个相邻小区的资源分配信息。
406、第一UE对第一网络设备发送的参考信号进行信号测量，得到第一测量结果。
407、第一UE在该第一测量结果小于第一阈值的情况下，通过接口将该相邻小区的资源分配信息上报给第一网络设备。
本发明实施例中，第一UE对第一网络设备发送的参考信号进行信号测量，得到第一测量结果后，第一UE也可以判断第一测量结果是否小于第一阈值，如果小于第一阈值，则表明第一UE处于第一网络设备的网络覆盖边缘，这时，第一UE才会将搜集到的相邻小区的资源分配信息通过第一接口或者第二接口上报给第一网络设备。其中，第一阈值可以是第一网络设备配置并发送给第一UE的。
可选的，第一UE还可以在确定出自己处于第一网络设备的网络覆盖边缘的时候，再执行步骤401～405搜集相邻小区的资源分配信息，从而上报给第一网络设备，本发明实施例不做限定。
进一步的，如果第一UE需要发送上行数据，第一UE还可以将获取到的相邻小区的资源分配信息与第一UE的BSR一起上报给第一网络设备，第一网络 设备从而根据相邻小区的资源分配信息以及第一UE所需要发送数据的大小等为第一UE分配适当的资源。
可选的，上述步骤406和步骤407可以为可选步骤，即当不使用以上两个步骤时，第一UE可以在接收到若干个第二UE发送的资源占用信息后，将整合后的相邻小区的资源分配信息发送给第一网络设备，或者第一UE可以在一定时间内接收若干个第二UE发送的资源占用信息，然后将整合后的相邻小区的资源分配信息发送给第一网络设备。
408、第一网络设备通过接口接收该相邻小区的资源分配信息，并为第一UE分配资源。
可见，在图4所描述的方法中，第一UE可以通过PC5接口接收位于第一UE附近，且位于第一UE所在服务小区的相邻小区的UE的资源占用信息，从而根据第二UE的资源占用信息确定出各个相邻小区的资源分配信息，然后通过接口将其上报给第一网络设备。通过这种方式，第一网络设备可以接收第一UE搜集的相邻小区的资源分配信息，而不需要通过X2接口从其他网络设备获取，这样可以在一定程度上减少X2接口的信令开销，如果在系统网络拥堵的情况下通过这种方式获取相邻小区的资源分配信息，还可以提高为UE分配资源的效率。
基于图1所示的网络架构，本发明实施例公开了又一种资源分配方法。请参阅图5，图5是本发明实施例公开的又一种资源分配方法的流程示意图。如图5所示，该资源分配方法可以包括以下步骤：
501、第一UE通过第一接口向第二网络设备发送第二请求消息。
本发明实施例中，第二网络设备可以理解为第一UE所在服务小区的相邻小区所属的网络设备，第一UE通过第一接口可以与第二网络设备建立连接。那么第一UE在需要获取相邻小区的资源分配信息的情况下，可以通过第一接口向第二网络设备发送第二请求消息。该第二请求消息携带有第一UE所在服务小区的小区标识，用于请求获取该服务小区的相邻小区的资源分配信息。
需要说明的是，第二网络设备可以为一个，也可以为多个，第二网络设备可以是上一实施例中第二UE所连接的网络设备，本发明实施例不做限定。
502、第二网络设备通过第一接口接收该第二请求消息。
503、第二网络设备根据该第二请求消息从第二网络设备所管理的各小区中确定第一UE所在服务小区的相邻小区，并获取该相邻小区的资源分配信息。
本发明实施例中，第二网络设备在接收到第二请求消息后，可以根据第二请求消息中携带的小区标识，从第二网络设备所管理的所有小区中确定出第一UE所在服务小区的相邻小区，从而获取该相邻小区的资源分配信息。
504、第二网络设备通过第一接口向第一UE发送该相邻小区的资源分配信息。
本发明实施例中，第二网络设备在获取到相邻小区的资源分配信息后，可以通过第一接口向第一UE发送该相邻小区的资源分配信息。
可选的，第二网络设备还可以通过第一接口或者第二接口向第一UE发送第二网络设备所管理的各小区的资源分配信息，该资源分配信息携带有各小区的小区标识。第一UE在接收到各小区的资源分配信息后，可以根据小区标识确定出第一UE所在服务小区的相邻小区的资源分配信息。第二网络设备还可以通过第一接口或者第二接口周期性的广播第二网络设备所管理的各小区的资源分配信息。
505、第一UE通过第一接口接收第二网络设备发送的该相邻小区的资源分配信息。
506、第一UE对第一网络设备发送的参考信号进行信号测量，得到第一测量结果。
507、第一UE在该第一测量结果小于第一阈值的情况下，通过接口将该相邻小区的资源分配信息上报给第一网络设备。
可选的，上述步骤506和步骤507可以为可选步骤，即当不使用以上两个步骤时，第一UE可以在接收到若干个第二网络设备发送的资源分配信息后，将整合后的相邻小区的资源分配信息发送给第一网络设备，或者第一UE可以在一定时间内接收若干个第二网络设备发送的资源分配信息，然后将整合后的相邻小区的资源分配信息发送给第一网络设备。
508、第一网络设备通过接口接收该相邻小区的资源分配信息，并为第一UE分配资源。
可见，在图5所描述的方法中，第一UE还可以通过PC5接口向相邻小区所属的网络设备发送资源分配信息获取请求，网络设备从而将相邻小区的资源分配信息发送的第一UE。第一UE也可以从接收的各网络设备广播的各小区的资源分配信息中确定出相邻小区的资源分配信息，然后通过接口将其上报给第一网络设备。通过这种方式，第一网络设备可以接收第一UE搜集的相邻小区的资源分配信息，而不需要通过X2接口从其他网络设备获取，这样可以在一定程度上减少X2接口的信令开销，如果在系统网络拥堵的情况下通过这种方式获取相邻小区的资源分配信息，还可以提高为UE分配资源的效率。
基于图1所示的网络架构，本发明实施例公开了一种网络设备协作为UE提供下行数据传输服务的方法。请参阅图6，图6是本发明实施例公开的一种网络设备协作为UE提供下行数据传输服务的方法的流程示意图。如图6所示，该方法可以包括以下步骤：
601、第一网络设备向第一UE发送测量配置和上报指示信息。
本发明实施例中，第一网络设备和第二网络设备可以同时为第一UE提供下行数据传输服务，第一网络设备为第一UE的服务网络设备，第二网络设备为第一UE的辅助传输点，第一网络设备和第二网络设备在相同的资源上向第一UE发送下行数据。
因此，第一网络设备在检测到有第一UE的下行数据时，可以向第一UE发送测量配置和上报指示信息。其中，该测量配置用于指示第一UE分别测量第一网络设备和第二网络设备的RSRP、RSRQ和SINR中的至少一种，上报指示信息用于指示第一UE分别向第一网络设备和第二网络设备上报与各自相关的信息。
602、第一UE接收该测量配置和上报指示信息，并根据测量配置对第一网络设备发送的参考信号进行信号测量，得到第一测量结果，对第二网络设备发送的参考信号进行信号测量，得到第二测量结果。
本发明实施例中，第一UE接收到测量配置和上报指示信息后，可以根据测量配置对第一网络设备发送的参考信号进行信号测量，得到第一测量结果，并对第二网络设备发送的参考信号进行信号测量，得到第二测量结果。
需要说明的是，第一测量结果仅仅表示本发明实施例中第一UE对第一网络设备发送的参考信号进行信号测量的测量结果，第二测量结果仅仅表示本发明实施例中第一UE对第二网络设备发送的参考信号进行信号测量的测量结果，与资源分配方法实施例中的第二测量结果的含义有所区别，本发明实施例在此不再赘述。
603、第一UE根据上报指示信息将第一测量结果上报给第一网络设备。
本发明实施例中，第一UE可以通过第一接口或者第二接口将第一测量结果上报给第一网络设备，该第一测量结果可以包括RSRP、RSRQ、SINR中的至少一种。
可选的，第一UE还可以将CQI、PMI以及下行数据反馈信息等与第一测量结果上报给第一网络设备。
604、第一网络设备接收第一测量结果，并根据第一测量结果调整向第一UE发送数据的发射功率或者调整向第一UE发送数据的调制编码方式或者向第一UE发送数据失败时确定是否重传。
605、第一UE根据上报指示信息，将第二测量结果通过第一接口发送给第二UE。
本发明实施例中，第二测量结果可以包括RSRP、RSRQ、SINR中的至少一种。第一UE在对第二网络设备发送的参考信号进行信号测量后，会通过第一接口将第二测量结果发送给第二UE。其中，第二UE为第二网络设备下处于连接态的UE。
606、第二UE通过第一接口接收第一UE发送的第二测量结果。
可选的，第一UE还可以将CQI、PMI以及下行数据反馈信息等与第二测量结果发送给第二UE，由第二UE将上述信息与第二测量结果一起上报给第二网络设备。
607、第二UE将第二测量结果上报给第二网络设备。
本发明实施例中，第二UE可以通过第一接口或者第二接口将第二测量结果上报给第二网络设备。
608、第二网络设备接收第二测量结果，并根据第二测量结果调整向第一UE发送数据的发射功率或者调整向第一UE发送数据的调制编码方式或者向 第一UE发送数据失败时确定是否重传。
本发明实施例中，第二网络设备在接收到第二测量结果后，可以根据第二测量结果调整向第一UE发送数据的发射功率以及在向第一UE发送数据失败时确定是否重传，或者调整向第一UE发送数据的资源。
举例来说，当第二网络设备接收到第一UE反馈的下行传输的否定响应(Negative Acknowledgement，NACK)信息时，第二网络设备会决定重传上次发送的数据包。或者，当第二网络设备接收到第一UE反馈的第二测量结果中，第一UE的接收功率太大，可以减少发射功率，或者相反。或者，根据第二测量结果调整向第一UE发送数据的资源。
可选的，第一UE可以通过第一接口直接将需要上报给第二网络设备的信息上报给第二网络设备，而不需要通过第二UE进行转发，进而可以减少信息传输的时延。
可见，在图6所描述的方法中，第一网络设备和第二网络设备在协同为第一UE提供下行数据传输服务的时候，第一UE对第二网络设备发送的参考信号的测量结果可以通过第二网络设备下的第二UE转发给第二网络设备。这样可以避免第一网络设备通过X2接口向第二网络设备转发第一UE的测量结果，从而可以减少X2接口的信令开销，并在系统网络拥堵的情况下，还可以减少网络设备之间的通信时延。
基于图1所示的网络架构，本发明实施例公开了一种网络设备。请参阅图7，图7是本发明实施例公开的一种网络设备的结构示意图。其中，图7所描述的网络设备700可以应用于图2～图5所示的方法实施例，执行第一网络设备所执行的操作。如图7所示，该网络设备700可以包括收发模块701和处理模702，其中：

上述处理模块702，用于根据该相邻小区的资源分配信息为第一UE分配资源。
具体的，处理模块702会结合相邻小区的资源分配信息，避免为第一UE分配资源时与附近且连接其他网络设备的UE的资源发生冲突，从而避免干扰网络设备700接收第一UE的上行数据或避免干扰位于第一UE所在服务小区的相邻小区的其他UE接收下行数据。
可选的，上述收发模块701，还可以用于通过接口接收第一UE上报的第一测量结果，并在该第一测量结果小于第一阈值的情况下，通过接口接收第一UE所在服务小区的相邻小区的资源分配信息。其中，该第一测量结果为第一UE对网络设备700发送的参考信号进行信号测量的测量结果。
第一测量结果可以包括但不限于SINR、RSRP和RSRQ中的至少一种。
通过这种方式，网络设备700只有对位于网络边缘的UE分配资源时才会获取该UE所在服务小区的相邻小区的资源分配信息，可以提高对非网络边缘的UE分配资源的效率。
具体的，上述收发模块701通过接口接收第一UE所在服务小区的相邻小区的资源分配信息的具体方式可以为：
通过第一接口发送请求消息，其中，该请求消息用于请求获取第一UE所在服务小区的相邻小区的资源分配信息；请求消息还可以携带第一UE所在服务小区的小区标识；

请参阅图8，图8是本发明实施例公开的另一种网络设备的结构示意图。其中，图8所描述的网络设备800可以应用于图2～图5所示的方法实施例，执行第一网络设备所执行的操作。如图8所示，该网络设备可以包括收发器801和处理器802，其中：
上述收发器801，用于通过接口接收第一UE所在服务小区的相邻小区的资源分配信息，其中，该相邻小区所属的网络设备与该网络设备800不同，该接口可以包括第一接口或者第二接口，第一接口为利用UE到UE通信技术进行通信的接口，如PC5接口、蓝牙配对的设备之间的接口、Wi-Fi连接的设备之间的接口等，第二接口为利用UE到网络设备通信技术进行通信的接口，如Uu接口。
上述处理器802，用于根据该相邻小区的资源分配信息为第一UE分配资源。
具体的，处理器802会结合相邻小区的资源分配信息，避免为第一UE分配资源时与附近且连接其他网络设备的UE的资源发生冲突，从而避免干扰网络设备800接收第一UE的上行数据或避免干扰位于第一UE所在服务小区的相邻小区的其他UE接收下行数据。
可选的，上述收发器801，还可以用于通过接口接收第一UE上报的第一测量结果，并在该第一测量结果小于第一阈值的情况下，通过接口接收第一UE所在服务小区的相邻小区的资源分配信息。其中，该第一测量结果为第一UE对网络设备800发送的参考信号进行信号测量的测量结果。
第一测量结果可以包括但不限于SINR、RSRP和RSRQ中的至少一种。
通过这种方式，网络设备800只有对位于网络边缘的UE分配资源时才会获取该UE所在服务小区的相邻小区的资源分配信息，可以提高对非网络边缘的 UE分配资源的效率。
具体的，上述收发器801通过接口接收第一UE所在服务小区的相邻小区的资源分配信息的具体方式可以为：
通过第一接口发送请求消息，其中，该请求消息用于请求获取第一UE所在服务小区的相邻小区的资源分配信息；请求消息还可以携带第一UE所在服务小区的小区标识；
通过第一接口接收第二网络设备根据该请求消息反馈的该相邻小区的资源分配信息，其中，该第二网络设备为该相邻小区所属的网络设备。
可选的，上述收发器801通过接口接收第一UE所在服务小区的相邻小区的资源分配信息的具体方式还可以为：
通过第一接口接收第二网络设备发送的该第二网络设备所管理的各小区的资源分配信息，并触发处理器802从该各小区的资源分配信息中确定第一UE所在服务小区的相邻小区的资源分配信息。
可选的，上述收发器801通过接口接收第一UE所在服务小区的相邻小区的资源分配信息的具体方式还可以为：
通过第一接口或者第二接口接收第一UE上报的该第一UE所在服务小区的相邻小区的资源分配信息。
可选的，上述收发器801通过第一接口接收网络设备800提供的小区的相邻小区所服务的UE发送的相邻小区的资源分配信息，该资源分配信息中携带这些UE所在的服务小区的小区标识，上述处理器802根据上述小区标识以及第一UE所在服务小区的小区标识可以确定出第一UE服务小区的相邻小区，进而确定出第一UE服务小区的相邻小区的资源分配信息。
可见，在图7或图8所描述的网络设备中，该网络设备可以通过PC5接口或者Uu接口接收第一UE上报的该第一UE所在服务小区的相邻小区的资源分配信息，也可以通过PC5接口接收其他网络设备发送的第一UE所在服务小区的相邻小区的资源分配信息，从而可以根据相邻小区的资源分配信息为第一UE分配资源，以避免与位于该相邻小区的UE使用相同的资源，从而减小对相邻小区的干扰，或者为第一UE分配对该UE干扰较小的资源，以减少相邻小区对第一UE的干扰。通过这种方式，可以减少网络设备之间的X2接口的信令开销， 并且在系统网络较为拥堵的情况下，还可以提高为UE分配资源的效率，从而能够在一定程度上减少UE传输数据的时延。
基于图1所示的网络架构，本发明实施例公开了一种用户设备。请参阅图9，图9是本发明实施例公开的一种用户设备的结构示意图。其中，图9所描述的用户设备UE900可以应用于图2～图5所示的方法实施例，执行第一UE所执行的操作。如图9所示，该UE900可以包括收发模块901和处理模902，其中：
上述收发模块901，用于接收UE900所在服务小区的相邻小区的资源分配信息，其中，该相邻小区所属的网络设备与该UE900所连接的第一网络设备不同。
上述收发模块901，还用于通过接口将该相邻小区的资源分配信息上报给第一网络设备，其中，该相邻小区的资源分配信息用于第一网络设备为UE900分配资源，接口包括第一接口或第二接口，第一接口为利用UE到UE通信技术进行通信的接口，如PC5接口、蓝牙配对的设备之间的接口、Wi-Fi连接的设备之间的接口等，第二接口为利用UE到网络设备通信技术进行通信的接口，如Uu接口。
需要说明的是，本发明实施例中提到的第一网络设备即为网络设备700。
可选的，上述处理模块902，用于对第一网络设备发送的参考信号进行信号测量，得到第一测量结果，并判断第一测量结果是否小于第一阈值，如果第一测量结果小于第一阈值，上述处理模块902则触发上述收发模块901通过接口将该相邻小区的资源分配信息上报给第一网络设备。
通过这种方式，UE900只有在位于第一网络设备的网络边缘的情况下，才会将获取到的UE900所在服务小区的相邻小区的资源分配信息上报给第一网络设备，以请求第一网络设备为其分配资源，这样可以提高网络设备为网络边缘的UE分配资源的效率。
具体的，上述收发模块901接收UE900所在服务小区的相邻小区的资源分配信息的具体方式可以为：
通过第一接口接收至少一个第二UE发送的该第二UE的资源占用信息，其 中，该资源占用信息为该第二UE所连接的网络设备为第二UE分配的资源的信息，该资源占用信息携带第二UE所在服务小区的小区标识，第二UE所在服务小区为UE900所在服务小区的相邻小区，且第二UE所连接的网络设备与第一网络设备不为同一网络设备；
触发上述处理模块902根据该小区标识从该至少一个第二UE发送的该第二UE的资源占用信息中确定携带有相同小区标识的资源占用信息，并根据该携带有相同小区标识的资源占用信息确定该相同小区标识所标记的小区的资源分配信息。
各个UE可以广播自己的资源占用信息，UE900在接收到相邻小区中各UE广播的资源占用信息后，可以根据资源占用信息携带的小区标识确定出各个相邻小区的资源分配信息，然后再将得到的资源分配信息上报给第一网络设备，这样可以避免网络设备之间通过X2接口交互资源分配信息，从而可以减少X2接口的信令开销。
可选的，上述收发模块901，还可以用于在通过第一接口接收至少一个第二UE发送的所述第二UE的资源占用信息之前，通过第一接口发送第一请求消息，其中，该第一请求消息用于请求获取UE900所在服务小区的相邻小区的UE的资源占用信息。该第一请求消息携带UE900所在服务小区的小区标识。
UE900可以向附近的UE发送请求，以获取相邻小区中各UE的资源占用信息，从而得到相邻小区的资源分配信息，然后再将得到的资源分配信息上报给第一网络设备，这样可以避免网络设备之间通过X2接口交互资源分配信息，从而可以减少X2接口的信令开销。
可选的，第一网络设备还可以向UE900发送获取UE900服务小区的相邻小区资源分配信息的请求消息，UE900在接收到该请求消息后通过第一接口发送第一请求消息。可选的，第一网络设备向UE900发送上述请求消息的触发条件可以为第一网络设备向第二网络设备发送资源分配信息请求信息的触发条件。
可选的，上述收发模块901接收UE900所在服务小区的相邻小区的资源分配信息的具体方式还可以为：
通过第一接口向第二网络设备发送第二请求消息，其中，该第二网络设备为UE900所在服务小区的相邻小区所属的网络设备，第二请求消息用于请求获取该相邻小区的资源分配信息；
通过第一接口接收第二网络设备根据第二请求消息发送的该相邻小区的资源分配信息。
UE900可以通过PC5接口向相邻小区所属的网络设备发送请求，以获取相邻小区的资源分配信息，这样可以避免网络设备之间通过X2接口交互资源分配信息，从而可以减少X2接口的信令开销。
可选的，上述收发模块901接收UE900所在服务小区的相邻小区的资源分配信息的具体方式还可以为：
通过第一接口或者第二接口接收第二网络设备发送的第二网络设备所管理的各小区的资源分配信息，并触发上述处理模块902从该各小区的资源分配信息中确定UE900所在服务小区的相邻小区的资源分配信息，第二网络设备为该相邻小区所属的网络设备。
网络设备可以通过第一接口或者第二接口向UE广播其所管理的各小区的资源分配信息，那么UE900在接收到后，可以从中确定出其所在服务小区的相邻小区的资源分配信息，并将其上报给第一网络设备，这样可以避免网络设备之间通过X2接口交互资源分配信息，从而可以减少X2接口的信令开销。
具体的，上述处理模块902根据该小区标识从该至少一个第二UE发送的第二UE的资源占用信息中确定携带有相同小区标识的资源占用信息的具体方式可以为：
在资源占用信息还携带第二测量结果的情况下，根据小区标识从第二测量结果小于第二阈值的该至少一个第二UE发送的第二UE的资源占用信息中确定携带有相同小区标识的资源占用信息，其中，第二测量结果为第二UE对第二UE所连接的网络设备发送的参考信号进行信号测量的测量结果；
或者，
对第二UE发送的参考信号进行信号测量，得到第三测量结果，并根据该小区标识从第三测量结果大于第三阈值的该至少一个第二UE发送的第二UE的资源占用信息中确定携带有相同小区标识的资源占用信息。
UE900可以确定出处于相邻小区边缘的UE的资源占用信息，并且由于UE900能够接收到这些UE发送的资源占用信息，所以可以确定这些UE处理相邻小区的边缘，同时距离第UE900较近。一般地，处于小区覆盖边缘的UE使用较大的功率进行上行发送，对邻区干扰较大，同时基站向边缘UE发送下行时也会使用较大功率，对邻区边缘UE干扰较大。如果UE900将这些UE的资源占用信息上报给第一网络设备，第一网络设备在为UE900分配资源时，可以避免与这些UE的占用资源发生冲突，进而减少对UE900以及这些UE的干扰。
UE900通过这种方式根据距离较近的UE的资源占用信息来确定相邻小区的资源分配信息，可以提高获取相邻小区的资源分配信息的精确度，从而使得第一网络设备为UE900分配的资源能够更加有效的避免对位于相邻小区的网络覆盖边缘的UE的数据传输产生影响，或者避免受位于相邻小区的网络覆盖边缘的UE的影响。
需要说明的是，本发明实施例中提及的第一测量结果为UE900对第一网络设备发送的参考信号进行信号测量的测量结果，第二测量结果为第二UE对第二UE所连接的网络设备发送的参考信号进行信号测量的测量结果，第三测量结果为UE900对第二UE发送的参考信号进行信号测量的测量结果，上述测量结果均可以包括但不限于SINR、RSRP和RSRQ中的至少一种。第一阈值、第二阈值以及第三阈值可以相同，也可以不同，本发明实施例不做限定。
请参阅图10，图10是本发明实施例公开的另一种用户设备的结构示意图。其中，图10所描述的UE1000可以应用于图2～图5所示的方法实施例，执行第一UE所执行的操作。如图10所示，该UE100可以包括收发器1001和处理器1002，其中：
上述收发器1001，用于接收UE1000所在服务小区的相邻小区的资源分配信息，其中，该相邻小区所属的网络设备与该UE1000所连接的第一网络设备不同。
上述收发器1001，还用于通过接口将该相邻小区的资源分配信息上报给第一网络设备，其中，该相邻小区的资源分配信息用于第一网络设备为UE900分配资源，接口包括第一接口或第二接口，第一接口为利用UE到UE通信技 术进行通信的接口，如PC5接口、蓝牙配对的设备之间的接口、Wi-Fi连接的设备之间的接口等，第二接口为利用UE到网络设备通信技术进行通信的接口，如Uu接口。
需要说明的是，本发明实施例中提到的第一网络设备即为网络设备800。
可选的，上述处理器1002，用于对第一网络设备发送的参考信号进行信号测量，得到第一测量结果，并判断第一测量结果是否小于第一阈值，如果第一测量结果小于第一阈值，上述处理模块902则触发上述收发器1001通过接口将该相邻小区的资源分配信息上报给第一网络设备。
通过这种方式，UE1000只有在位于第一网络设备的网络边缘的情况下，才会将获取到的UE1000所在服务小区的相邻小区的资源分配信息上报给第一网络设备，以请求第一网络设备为其分配资源，这样可以提高网络设备对非网络边缘的UE分配资源的效率。
具体的，上述收发器1001接收UE1000所在服务小区的相邻小区的资源分配信息的具体方式可以为：
通过第一接口接收至少一个第二UE发送的该第二UE的资源占用信息，其中，该资源占用信息为该第二UE所连接的网络设备为第二UE分配的资源的信息，该资源占用信息携带第二UE所在服务小区的小区标识，第二UE所在服务小区为UE1000所在服务小区的相邻小区，且第二UE所连接的网络设备与第一网络设备不为同一网络设备；
触发上述处理器1002根据该小区标识从该至少一个第二UE发送的该第二UE的资源占用信息中确定携带有相同小区标识的资源占用信息，并根据该携带有相同小区标识的资源占用信息确定该相同小区标识所标记的小区的资源分配信息。
各个UE可以广播自己的资源占用信息，UE1000在接收到相邻小区中各UE广播的资源占用信息后，可以根据资源占用信息携带的小区标识确定出各个相邻小区的资源分配信息，然后再将得到的资源分配信息上报给第一网络设备，这样可以避免网络设备之间通过X2接口交互资源分配信息，从而可以减少X2接口的信令开销。
可选的，上述收发器1001，还可以用于在通过第一接口接收至少一个第 二UE发送的所述第二UE的资源占用信息之前，通过第一接口发送第一请求消息，其中，该第一请求消息用于请求获取UE1000所在服务小区的相邻小区的UE的资源占用信息。该第一请求消息携带UE1000所在服务小区的小区标识。
UE1000可以向附近的UE发送请求，以获取相邻小区中各UE的资源占用信息，从而得到相邻小区的资源分配信息，然后再将得到的资源分配信息上报给第一网络设备，这样可以避免网络设备之间通过X2接口交互资源分配信息，从而可以减少X2接口的信令开销。
可选的，第一网络设备还可以向UE900发送获取UE900服务小区的相邻小区资源分配信息的请求消息，UE900在接收到该请求消息后通过第一接口发送第一请求消息。可选的，第一网络设备向UE900发送上述请求消息的触发条件可以为第一网络设备向第二网络设备发送资源分配信息请求信息的触发条件。
可选的，上述收发器1001接收UE1000所在服务小区的相邻小区的资源分配信息的具体方式还可以为：
通过第一接口向第二网络设备发送第二请求消息，其中，该第二网络设备为UE900所在服务小区的相邻小区所属的网络设备，第二请求消息用于请求获取该相邻小区的资源分配信息；
通过第一接口接收第二网络设备根据第二请求消息发送的该相邻小区的资源分配信息。
UE1000可以通过PC5接口向相邻小区所属的网络设备发送请求，以获取相邻小区的资源分配信息，这样可以避免网络设备之间通过X2接口交互资源分配信息，从而可以减少X2接口的信令开销。
可选的，上述收发器1001接收UE1000所在服务小区的相邻小区的资源分配信息的具体方式还可以为：
通过第一接口或者第二接口接收第二网络设备发送的第二网络设备所管理的各小区的资源分配信息，并触发上述处理器1002从该各小区的资源分配信息中确定UE1000所在服务小区的相邻小区的资源分配信息，第二网络设备为该相邻小区所属的网络设备。
网络设备可以通过第一接口或者第二接口向UE广播其所管理的各小区的 资源分配信息，那么UE1000在接收到后，可以从中确定出其所在服务小区的相邻小区的资源分配信息，并将其上报给第一网络设备，这样可以避免网络设备之间通过X2接口交互资源分配信息，从而可以减少X2接口的信令开销。
具体的，上述处理器1002根据该小区标识从该至少一个第二UE发送的第二UE的资源占用信息中确定携带有相同小区标识的资源占用信息的具体方式可以为：
在资源占用信息还携带第二测量结果的情况下，根据小区标识从第二测量结果小于第二阈值的该至少一个第二UE发送的第二UE的资源占用信息中确定携带有相同小区标识的资源占用信息，其中，第二测量结果为第二UE对第二UE所连接的网络设备发送的参考信号进行信号测量的测量结果；
或者，
对第二UE发送的参考信号进行信号测量，得到第三测量结果，并根据该小区标识从第三测量结果大于第三阈值的该至少一个第二UE发送的第二UE的资源占用信息中确定携带有相同小区标识的资源占用信息。
UE1000可以确定出处于相邻小区边缘的UE的资源占用信息，并且由于UE1000能够接收到这些UE发送的资源占用信息，所以可以确定这些UE处理相邻小区的边缘，同时距离UE1000较近。一般地，处于小区覆盖边缘的UE使用较大的功率进行上行发送，对邻区干扰较大，同时基站向边缘UE发送下行时也会使用较大功率，对邻区边缘UE干扰较大。如果UE1000将这些UE的资源占用信息上报给第一网络设备，第一网络设备在为UE1000分配资源时，可以避免与这些UE的占用资源发生冲突，进而减少对UE1000以及这些UE的干扰。
UE1000根据距离较近的UE的资源占用信息来确定相邻小区的资源分配信息，可以提高获取相邻小区的资源分配信息的精确度，从而使得第一网络设备为UE1000分配的资源能够更加有效的避免对位于相邻小区的网络覆盖边缘的UE的数据传输产生影响，或者避免受位于相邻小区的网络覆盖边缘的UE的影响。
需要说明的是，本发明实施例中提及的第一测量结果为UE1000对第一网络设备发送的参考信号进行信号测量的测量结果，第二测量结果为第二UE对 第二UE所连接的网络设备发送的参考信号进行信号测量的测量结果，第三测量结果为UE1000对第二UE发送的参考信号进行信号测量的测量结果，上述测量结果均可以包括但不限于SINR、RSRP和RSRQ中的至少一种。第一阈值、第二阈值以及第三阈值以相同，也可以不同，本发明实施例不做限定。
可见，在图9或者图10所描述的用户设备中，用户设备可以通过PC5接口接收位于相邻小区的UE的资源占用信息，从而确定出相邻小区的资源分配信息，也可以通过PC5接口或者Uu接口从其他网络设备获取相邻小区的资源分配信息，并上报给第一网络设备，这样可以避免网络设备之间通过X2接口交互资源分配信息，从而可以减少X2接口的信令开销，并在系统网络拥堵的情况下，可以提高资源分配信息的获取效率。
基于图1所示的网络架构，本发明实施例公开了又一种用户设备。请参阅图11，图11是本发明实施例公开的又一种用户设备的结构示意图。其中，图11所描述的UE1100可以应用于图2～图5所示的方法实施例，执行第二UE所执行的操作。如图11所示，该UE1100可以包括收发模块1101和处理模块1102，其中：
上述收发模块1101，用于通过第一接口接收第一UE发送的第一请求消息，其中，该第一请求消息用于请求获取第一UE所在服务小区的相邻小区的UE的资源占用信息，该第一接口为利用UE到UE通信技术进行通信的接口，如PC5接口、蓝牙配对的设备之间的接口、Wi-Fi连接的设备之间的接口等，该第一请求消息可以包括第一UE所在服务小区的小区标识，以及第一UE所连接的第一网络设备的标识。
上述处理模块1102，用于根据该小区标识确定UE1100所在服务小区为第一UE所在服务小区的相邻小区，且根据第一网络设备的标识确定UE1100所连接的网络设备与第一网络设备不同。
上述收发模块1101，用于通过第一接口将UE1100的资源占用信息发送给第一UE。
可选的，上述处理模块1102，还可以用于对UE1100所连接的网络设备发送的参考信号进行信号测量，得到第二测量结果，并在第二测量结果小于第二 阈值的情况下，触发上述收发模块1101通过第一接口将UE1100的资源占用信息发送给第一UE。
通过这种方式，UE1100在接收到第一UE发送的第一请求消息后，只有在确定出自己处于网络覆盖边缘的时候才会将其资源占用信息发送给第一UE，从而可以提高第一UE获取相邻小区对第一UE存在干扰隐患的资源分配信息的精确度，使得第一网络设备为第一UE分配的资源能够更加有效的避免对位于相邻小区覆盖边缘的UE的数据传输产生影响，或者避免受位于相邻小区覆盖边缘的UE的影响。
可选的，上述收发模块1101通过第一接口将UE1100的资源占用信息发送给第一UE的具体方式可以为：
在第一请求消息还包括第一UE对第一网络设备发送的参考信号进行信号测量的第一测量结果，且第一测量结果小于第一阈值的情况下，通过第一接口将UE1100的资源占用信息发送给第一UE。
UE1100在接收到第一请求消息时，可以判断第一UE是否处于第一网络设备的网络覆盖边缘，如果处于第一网络设备的网络覆盖边缘，才会将其资源占用信息发送给第一UE，从而可以避免将其资源占用信息发送给第一网络设备的非网络覆盖边缘的UE，从而可以避免不必要信息的发送，减少第一接口上的信令开销。
请参阅图12，图12是本发明实施例公开的又一种用户设备的结构示意图。其中，图12所描述的UE1200可以应用于图2～图5所示的方法实施例，执行第二UE所执行的操作。如图12所示，该UE1200可以包括收发器1201和处理器1202，其中：
上述收发器1201，用于通过第一接口接收第一UE发送的第一请求消息，其中，该第一请求消息用于请求获取第一UE所在服务小区的相邻小区的UE的资源占用信息，该第一接口为利用UE到UE通信技术进行通信的接口，如PC5接口、蓝牙配对的设备之间的接口、Wi-Fi连接的设备之间的接口等，该第一请求消息可以包括第一UE所在服务小区的小区标识，以及第一UE所连接的第一网络设备的标识。
上述处理器1202，用于根据该小区标识确定UE1200所在服务小区为第一 UE所在服务小区的相邻小区，且根据第一网络设备的标识确定UE1200所连接的网络设备与第一网络设备不同。
上述收发器1201，用于通过第一接口将UE1200的资源占用信息发送给第一UE。
可选的，上述处理器1202，还可以用于对UE1200所连接的网络设备发送的参考信号进行信号测量，得到第二测量结果，并在第二测量结果小于第二阈值的情况下，触发上述收发模块1101通过第一接口将UE1200的资源占用信息发送给第一UE。
通过这种方式，UE1200在接收到第一UE发送的第一请求消息后，只有在确定出自己处于网络覆盖边缘的时候才会将其资源占用信息发送给第一UE，从而可以提高第一UE获取相邻小区对第一UE存在干扰隐患的资源分配信息的精确度，使得第一网络设备为第一UE分配的资源能够更加有效的避免对位于相邻小区覆盖边缘的UE的数据传输产生影响，或者避免受位于相邻小区覆盖边缘的UE的影响。
可选的，上述收发器1201通过第一接口将UE1200的资源占用信息发送给第一UE的具体方式可以为：
在第二请求消息还包括第一UE对第一网络设备发送的参考信号进行信号测量的第一测量结果，且第一测量结果小于第一阈值的情况下，通过第一接口将UE1200的资源占用信息发送给第一UE。
UE1200在接收到第一请求消息时，可以判断第一UE是否处于第一网络设备的网络覆盖边缘，如果处于第一网络设备的网络覆盖边缘，才会将其资源占用信息发送给第一UE，从而可以避免将其资源占用信息发送给第一网络设备的非网络覆盖边缘的UE，从而可以避免不必要信息的发送，减少第一接口上的信令开销。
可见，在图11或图12所描述的用户设备中，位于相邻小区的网络覆盖边缘UE在接收到第一UE发送的获取相邻小区的UE的资源占用信息的请求消息后，相邻小区的UE通过PC5接口将其资源占用信息发送给第一UE，第一UE从而根据资源占用信息确定相邻小区的资源分配信息，以便于第一UE所连接的网络设备可以根据相邻小区的资源分配信息为第一UE分配的资源能够 更加有效的避免对该相邻小区的UE的数据传输产生影响，或者避免受该相邻小区的UE的影响。
基于图1所示的网络架构，本发明实施例公开了又一种用户设备。请参阅图13，图13是本发明实施例公开的又一种用户设备的结构示意图。其中，图13所描述的UE1300可以应用于图6所示的方法实施例，执行第一UE所执行的操作。如图13所示，该UE1300可以包括收发模块1301和处理模块1302，其中：
上述收发模块1301，用于接收第一网络设备发送的测量配置和上报指示信息。
上述处理模块1302，用于根据测量配置对第一网络设备发送的参考信号进行信号测量，得到第一测量结果，对第二网络设备发送的参考信号进行信号测量，得到第二测量结果。
上述收发模块1301，还用于根据上报指示信息将第一测量结果上报给第一网络设备，以便于第一网络设备根据第一测量结果调整向UE1300发送数据的发射功率或者调整向UE1300发送数据的调制编码方式或者向UE1300发送数据失败时确定是否重传。
上述收发模块1302，还用于根据上报指示信息将第二测量结果通过第一接口发送给第二UE。其中，第二UE为第二网络设备下处于连接态的UE。
因此，第二UE在接收到第二测量结果后，可以将其上报给第二网络设备，以便于第二网络设备可以根据第二测量结果调整向UE1300发送数据的发射功率或者在向UE1300发送数据失败时确定是否重传，或者调整向UE1300发送数据的资源，或者调整向UE1300发送数据的调制编码方式。
请参阅图14，图14是本发明实施例公开的又一种用户设备的结构示意图。其中，图14所描述的UE1400可以应用于图6所示的方法实施例，执行第一UE所执行的操作。如图14所示，该UE1400可以包括收发器1401和处理器1402，其中：
上述收发器1401，用于接收第一网络设备发送的测量配置和上报指示信息。
上述处理器1402，用于根据测量配置对第一网络设备发送的参考信号进行信号测量，得到第一测量结果，对第二网络设备发送的参考信号进行信号测量，得到第二测量结果。
上述收发器1401，还用于根据上报指示信息将第一测量结果上报给第一网络设备，以便于第一网络设备根据第一测量结果调整向UE1400发送数据的发射功率或者调整向UE1400发送数据的调制编码方式或者向UE1400发送数据失败时确定是否重传。
上述收发器1402，还用于根据上报指示信息将第二测量结果通过第一接口发送给第二UE。其中，第二UE为第二网络设备下处于连接态的UE。
因此，第二UE在接收到第二测量结果后，可以将其上报给第二网络设备，以便于第二网络设备可以根据第二测量结果调整向UE1400发送数据的发射功率或者在向UE1400发送数据失败时确定是否重传，或者调整向UE1400发送数据的资源，或者调整向UE1300发送数据的调制编码方式。
可见，在图13或图14所描述的用户设备中，第一网络设备和第二网络设备在协同为UE提供下行数据传输服务的时候，UE对第二网络设备发送的参考信号的测量结果可以通过第二网络设备下的第二UE转发给第二网络设备。这样可以避免第一网络设备通过X2接口向第二网络设备转发UE的测量结果，从而可以减少X2接口的信令开销，并在系统网络拥堵的情况下，还可以减少网络设备之间的通信时延。
基于图1所示的网络架构，本发明实施例公开了一种资源分配系统。请参阅图15，图15是本发明实施例公开的一种资源分配系统的结构示意图。如图15所示，该资源分配系统可以包括第一UE1501、第二UE1502、第一网络设备1503以及第二网络设备1504，第一UE1501位于第一网络设备1503的网络覆盖边缘，第一UE1501所在服务小区与第二UE1502所在服务小区为相邻小区，第二UE1502可以也位于其连接的网络设备的覆盖边缘，该网络设备与第一网络设备1503不同，可以为第二网络设备1504，也可以不为第二网络设备1504，本发明实施例不做限定，第二网络设备1504为第一UE1501所在服务小区的相邻小区所属的网络设备，其中：
第一UE1501通过接口向第一网络设备1503发送第一UE1501所在服务小区的相邻小区的资源分配信息，其中，该相邻小区所属的网络设备与第一网络设备1503不同。
第一网络设备1503通过接口接收第一UE1501发送的该相邻小区的资源分配信息，并根据该资源分配信息为第一UE1501分配资源。
具体的，第一网络设备1503会结合相邻小区的资源分配信息，避免为第一UE1501分配资源时与附近且连接其他网络设备的UE的资源发生冲突，从而避免干扰第一网络设备1503接收第一UE1501的上行数据或避免干扰位于第一UE1501所在服务小区的相邻小区的其他UE接收下行数据。
可选的，第一网络设备1503还可以通过第一接口发送请求消息，该请求消息用于请求获取第一UE1501所在服务小区的资源分配信息。
第二网络设备1504接收该请求消息，并将第二网络设备1504所管理的各小区中第一UE1501所在服务小区的相邻小区的资源分配信息发送给第一网络设备1503。
可选的，第二网络设备1504可以通过第一接口广播其管理的各小区的资源分配信息。那么第一网络设备1503在通过第一接口接收到第二网络设备1054管理的各小区的资源分配信息后，可以从中确定出第一UE1501所在服务小区的相邻小区的资源分配信息。
进一步的，第一UE1501获取其所在服务小区的相邻小区的资源分配信息的方式具体可以为：
方式一、
第一UE1501通过第一接口发送第一请求消息，该第一请求消息用于请求获取其所在服务小区的相邻小区的UE的资源占用信息。第二UE1502在接收到第一请求消息后，会将其资源占用信息通过第一接口发送给第一UE1501。第一UE1501对接收到的资源占用信息按照不同的小区进行归类，从而得到相邻小区的资源分配信息。
方式二、
第二UE1502会通过第一接口广播自己的资源占用信息，第一UE从而可以通过第一接口接收其资源占用信息，然后按照不同的小区进行归类，得到相 邻小区的资源分配信息。
方式三、
第一UE1501通过第一接口向第二网络设备1504发送第二请求消息，该第二请求消息用于请求获取第一UE1501所在服务小区的相邻小区的资源分配信息。第二网络设备1504在接收到第二请求消息后，会将其所管理的各小区中第一UE1501所在服务小区的相邻小区的资源分配信息通过第一接口发送给第一UE1501。
方式四、
第二网络设备1504可以通过第一接口或者第二接口广播自己管理的各小区的资源分配信息，第一UE1501在接收到其广播的各小区的资源分配信息后，可以从中确定出第一UE1501所在服务小区的相邻小区的资源分配信息。
进一步的，该系统中第一网络设备1503和第二网络设备1504可以协同为第一UE1501的下行数据提供服务。假设第二UE1502所连接的网络设备为第二网络设备1504，那么第一UE1501在对第二网络设备1504发送的参考信号进行信号测量的测量结果可以通过第一接口发送给第二UE1502，由第二UE1502转发给第二网络设备1504，第二网络设备1504从而可以根据车辆结果调整向第一UE1501发送数据的发射功率，或者调整向第一UE1501发送数据所使用的资源，或者在向第一UE1501发送数据失败时确定是否重传等。
通过该系统可以减少第一网络设备1503与第二网络设备1504之间为第一UE1501提供下行数据服务时X2接口的信令开销，并在系统网络拥堵的情况下，还可以减少网络设备之间的通信时延。
可见，在图15所描述的系统中，第一网络设备可以通过PC5接口或者Uu接口接收第一UE上报的该第一UE所在服务小区的相邻小区的资源分配信息，也可以通过PC5接口接收其他网络设备发送的第一UE所在服务小区的相邻小区的资源分配信息，从而可以根据相邻小区的资源分配信息为第一UE分配资源，以避免与位于该相邻小区的UE使用相同的资源，从而减小对相邻小区的干扰，或者为第一UE分配对该UE干扰较小的资源，以减少相邻小区对第一UE的干扰。通过这种方式，可以减少网络设备之间的X2接口的信令开销，并且在系统网络较为拥堵的情况下，还可以提高为UE分配资源的效率， 从而能够在一定程度上减少UE传输数据的时延。
目前，设备到设备(Device-to-Device，D2D)通信主要应用于公共安全(Public Safety，PS)类业务，PS类业务被分配有专用的资源以进行D2D数据的传输，即D2D数据具体为PS类业务的通信数据。随着车联网技术的发展，D2D数据有了更广泛的意义，即D2D数据不仅包括PS类业务的通信数据，还可以包括车到一切(Vehicle to everything，V2X)类业务的通信数据。目前的D2D数据的处理过程中，在数据发送之前，并不能将不同业务类型的通信数据区别开来，这样就会导致所有的数据会被承载到同一资源上进行传输，在这种情况下，可能就会出现只需要V2X类业务的通信数据的终端设备在该资源上会接收到非V2X类业务的通信数据，并且终端设备需要对接收到的数据进行解析才能得到需要的数据。可见，这种方式在一定程度上会增加接收端的功耗。
为了解决上述问题，本发明实施例公开了又一种资源分配方法，该方法可以应用于图1所示的网络架构中—具体为两个设备(UE与网络设备或两个UE)之间基于第一接口(如PC5接口)进行通信的场景，具体可以是D2D通信场景。
请参阅图16，图16是本发明实施例公开的又一种资源分配方法的流程示意图。如图16所示，该方法可以包括以下步骤：
1601、UE根据待传输D2D数据的第一业务类型建立与该第一业务类型对应的逻辑信道。
本发明实施例中，待传输D2D数据，即UE生成的D2D通信数据，用于与另一UE或者另一终端设备之间通过PC5接口进行通信的数据。D2D数据可以为PS类业务的通信数据，也可以为车联网类业务的通信数据，还可以为非PS非车联网类业务的通信数据。也就是说，D2D数据的业务类型可以包括PS类业务和车联网类业务，甚至还可以包括非PS非车联网类业务。第一业务类型包括车联网类业务。
其中，车联网类业务可以指V2X类业务，具体可以包括车到网络设施(Vehicle to Infrastructure，V2I)、车到车(Vehicle to Vehicle，V2V)、车到行人(Vehicle to Pedestrian，V2P)以及车到网络(Vehicle to Network，V2N)等。那么UE在生成待传输D2D数据，且确定其业务类型(待传输D2D数据的业务类型称为第一业务类型)后，可以根据该第一业务类型建立与该第一业务类型 对应的逻辑信道。
需要说明的是，与第一业务类型对应的逻辑信道可以理解为：为V2X类业务的D2D数据建立专用的逻辑信道；或者建立D2D的逻辑信道，即沿用为PS类业务的D2D数据建立逻辑信道的过程来建立逻辑信道，但需要标记上哪些逻辑信道用于承载V2X类业务的D2D数据，哪些逻辑信道用于承载PS类业务的D2D数据。具体可以是，UE在为待传输D2D数据建立逻辑信道时，可以在该逻辑信道上标记该第一业务类型的标识。
举例来说，当待传输D2D数据的第一业务类型为PS类业务时，UE会将建立的与第一业务类型对应的逻辑信道标记为PS类业务的逻辑信道；当待传输D2D数据的第一业务类型为V2X类业务时，UE会将建立的与第一业务类型对应的逻辑信道标记为V2X类业务的逻辑信道。
具体的，在UE侧，应用层或高层指示数据链路层(也称层二，Layer 2,L2)生成D2D数据的业务类型，具体可以是指示分组数据汇聚协议子层(Packet Data Convergence Protocol，PDCP)或无线链路控制子层(Radio Link Control，RLC)或媒体接入控制(Media Access Control，MAC)层其生成D2D数据的业务类型。例如，高层生成的D2D数据为PS类业务的数据，则高层指示MAC层该D2D数据的业务类型为PS类业务；如果高层生成的D2D数据为V2X类业务的数据，则高层指示MAC层该D2D数据的业务类型为V2X类业务。
1602、该UE从资源分配信息所分配的资源中确定用于承载该逻辑信道上的该待传输D2D数据的资源。
本发明实施例中，UE在建立用于承载待传输D2D数据的逻辑信道之后，可以从资源分配信息所分配的资源中确定用于该逻辑信道上的该待传输D2D数据的资源。其中，该资源分配信息所分配的资源可以是用于承载D2D数据的资源，该资源分配信息可以包括载波信息，如载波频率、载波频率上可进行的业务、用于承载D2D数据的物理资源块(Physical Resource Block，PRB)信息等，本发明实施例不做限定。
具体的，UE的资源分配信息中可以包括对应资源所承载数据的业务类型，那么UE就可以根据业务类型从承载D2D数据的资源中选取用于承载第一业务类型的D2D数据的资源，这样UE就可以在该资源上发送待传输D2D数据。
可选的，该UE从资源分配信息所分配的资源中确定用于承载该逻辑信道 上的该待传输D2D数据的资源之前，可以先获取用于承载D2D数据的资源的资源分配信息。其中，该资源分配信息可以包括该用于承载D2D数据的资源的数据承载方式。
该UE从资源分配信息所分配的资源中确定用于承载该逻辑信道上的该待传输D2D数据的资源的具体方式就可以为：
该UE根据该数据承载方式，从该用于承载D2D数据的资源中确定用于承载该逻辑信道上的待传输D2D数据的资源。
需要说明的是，用于承载D2D数据的资源的数据承载方式(可以称为资源分配信息所分配资源的用途)有两种，一种是独享资源方式，另一种是共享资源方式。其中，独享资源方式，即不同业务类型的D2D数据使用不同的资源发送；共享资源方式，即不同业务类型的D2D数据使用相同的资源发送。那么UE在确定出用于承载D2D数据的资源的数据承载方式之后，就可以根据具体的数据承载方式从资源分配信息所分配的资源中确定用于承载该逻辑信道上的该待传输D2D数据的资源。
具体可以是，当该数据承载方式为独享资源方式时，该资源分配信息还可以包括用于承载D2D数据的资源所承载的D2D数据的第二业务类型。那么UE可以将用于承载D2D数据的资源中所承载的D2D数据的第二业务类型与第一业务类型一致的资源确定为用于承载该逻辑信道上的待传输D2D数据的资源。
又举例来说，假设某一资源的资源分配信息具体包括：用于承载D2D数据的载波为F1，F1可以用于承载PS类业务的D2D数据和V2X类业务的D2D数据(即共享资源方式)。那么UE就会将PS类业务的D2D数据和V2X类业务的D2D数据映射到F1上进行复用并发送；如果用于承载D2D数据的载波为F1和F2，F1用于承载PS类业务的D2D数据，F2用于承载V2X类业务的D2D数据，那么UE就会将PS类业务的D2D数据映射到F1上进行复用并发送，而将V2X类业务的D2D数据映射到F2上进行复用并发送。
可选的，UE获取用于承载D2D数据的资源的资源分配信息的具体方式可以为：
该UE从预配置的资源中获取用于承载D2D数据的资源的资源分配信息；
或者，
该UE接收网络设备发送的用于承载D2D数据的资源的资源分配信息。
具体的，预配置的资源可以理解为：网络设备通过专用信令或广播消息为该UE分配的资源，或者UE存储于自身的存储器或者客户识别模块(Subscriber Identity Module，SIM)中的资源。
具体的，该UE接收网络设备发送的用于承载D2D数据的资源的资源分配信息的具体方式可以包括：该UE直接接收网络设备通过广播消息或者专用信令指示UE用于D2D通信的资源分配信息；或者，该UE先向网络设备上报业务类型指示信息，网络设备在接收到该指示信息后再向该UE发送用于承载D2D数据的资源的资源分配信息。
其中，该指示信息用于指示承载数据的业务类型，也就是说，网络设备在向UE发送用于承载D2D数据的资源的资源分配信息时，该资源分配信息可以包括用于承载D2D数据的资源的数据承载方式以及用于承载D2D数据的业务类型。该指示信息可以携带于资源请求消息中，该资源请求消息包括侧行UE信息(Sidelink UE Information)、BSR等。
可见，在图16所描述的方法中，UE可以根据其生成的D2D数据的业务类型标记逻辑信道，然后通过区分来自网络设备或自身预配置的资源分配信息所分配资源的数据承载方式，在发送D2D数据过程中可以独享资源，从而能够提高资源使用的灵活性，并能够减少接收端接收数据的功耗。
请参阅图17，图17是本发明实施例公开的又一种用户设备的结构示意图。其中图17所描述的UE1700可以应用于图16所示的方法实施例。如图17所示，该UE1700可以包括处理模块1701和收发模块1702，其中：
上述处理模块1701，用于根据待传输D2D数据的第一业务类型建立与该第一业务类型对应的逻辑信道，并从资源分配信息所分配的资源中确定用于承载该逻辑信道上的该待传输D2D数据的资源。
其中，第一业务类型包括车联网类业务，车联网类业务可以指V2X类业务。与第一业务类型对应的逻辑信道可以理解为：为V2X类业务的D2D数据建立专用的逻辑信道；或者建立D2D的逻辑信道，即沿用为PS类业务的D2D数据建立逻辑信道的过程来建立逻辑信道，但需要标记上哪些逻辑信道用于承载V2X类业务的D2D数据，哪些逻辑信道用于承载PS类业务的D2D数据。 具体可以是，处理模块1701在为待传输D2D数据建立逻辑信道时，可以在该逻辑信道上标记该第一业务类型的标识。
具体的，该资源分配信息所分配的资源可以是用于承载D2D数据的资源，该资源分配信息可以包括载波信息，如载波频率、载波频率上可进行的业务、用于承载D2D数据的PRB信息等，本发明实施例不做限定。UE1700的资源分配信息中还可以包括对应资源所承载数据的业务类型，那么处理模块1701就可以根据业务类型从承载D2D数据的资源中选取用于承载第一业务类型的D2D数据的资源，这样UE1700就可以在该资源上发送待传输D2D数据。

可选的，处理器1801从资源分配信息所分配的资源中确定用于承载该逻辑信道上的该待传输D2D数据的资源之前，收发器1802可以先获取用于承载D2D数据的资源的资源分配信息。其中，该资源分配信息可以包括该用于承载D2D数据的资源的数据承载方式。
处理器1801从资源分配信息所分配的资源中确定用于承载该逻辑信道上的该待传输D2D数据的资源的具体方式就可以为：
根据该数据承载方式，从该用于承载D2D数据的资源中确定用于承载该逻辑信道上的待传输D2D数据的资源。
需要说明的是，用于承载D2D数据的资源的数据承载方式(可以称为资源分配信息所分配资源的用途)有两种，一种是独享资源方式，另一种是共享资源方式。其中，独享资源方式，即不同业务类型的D2D数据使用不同的资源发送；共享资源方式，即不同业务类型的D2D数据使用相同的资源发送。那么处理器1801在确定出用于承载D2D数据的资源的数据承载方式之后，就可以根据具体的数据承载方式从资源分配信息所分配的资源中确定用于承载该逻辑信道上的该待传输D2D数据的资源。
可选的，当该数据承载方式为独享资源方式时，该资源分配信息还可以包括用于承载D2D数据的资源所承载的D2D数据的第二业务类型。那么处理器1801可以将用于承载D2D数据的资源中所承载的D2D数据的第二业务类型与第一业务类型一致的资源确定为用于承载该逻辑信道上的待传输D2D数据的资源。
