技术领域

背景技术
长期演进(Long Term Evolution，LTE)系统从第12个发布版本开始支持副链路(Sidelink，Sidelink或译为副链路，边链路等)，副链路用于用户设备(User Equipment，UE)之间不通过网络设备(比如基站)，而是进行直接数据传输。图1是用户设备之间可以通过副链路进行直接数据传输的示意图。
目前LTE支持Sidelink中继(relay)，中继是指基站或用户不直接将信号发送给彼此，而是通过中继节点，经过信号放大或再生处理进行转发。以简单的两跳中继系统为例，就是将一条基站至移动台的链路分割为基站至中继节点和中继节点至移动台的两条链路，从而能够将一条质量较差的链路替换为两条质量较好的链路，以获得更高的链路容量和更好的覆盖。
相关技术中，远端用户设备(remote UE)和中继用户设备(relay UE)可以进行直接数据传输。但是，在remote UE和relay UE进行直接数据传输之前，remote UE和relay UE需要获取用于数据传输的资源。但是，在相关技术的通信系统中，remote UE和relay UE获取用于数据传输的资源并不灵活。

具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例进行清楚、完整地描述，显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
图2示出了根据本公开的一个实施例的资源请求方法的原理示意图。
如图2所示，该资源请求方法包括：
S002：远端用户设备(remote UE)向网络设备发送第一BSR(Buffer Status Report，缓存状态报告BSR)，第一BSR用于向网络设备请求第二资源，第二资源是用于中继用户设备(relay UE)到网络设备数据传输的资源；
S004：网络设备接收第一BSR，根据第一BSR，分配第二资源；
S006：网络设备向中继用户设备发送第二资源的分配信息。
在本公开实施例中，远端用户设备发送的第一BSR可以请求中继用户设备到网络设备数据传输的第二资源，从而提高了资源获取的灵活度。
在本公开的一个实施例中，第一BSR还可用于向网络设备请求第一资 源，第一资源是远端用户设备到中继用户设备数据传输的资源。
下面结合图3说明本公开的实施例，图3示出了根据本公开另一个实施例的资源请求方法的时序图。如图3所示，资源请求方法包括：
S102：远端用户设备(remote UE)向网络设备发送第一BSR，第一BSR用于向网络设备请求第一资源和第二资源，第一资源是用于远端用户设备到中继用户设备(relay UE)数据传输的资源，第二资源是用于中继用户设备到网络设备数据传输的资源。
其中，第一BSR是Uplink BSR，第一资源是Sidelink资源，第二资源是上行(Uplink)资源。在远端用户设备有上行数据待发送时，远端用户设备发送Uplink BSR给基站，Uplink BSR向基站请求将待发送的上行数据从remote UE传输到relay UE的Sidelink资源以及请求将待发送的上行数据从relay UE传输到基站的Uplink资源。
资源请求方法还包括：
S104：网络设备接收第一BSR；根据第一BSR，分配第一资源和第二资源；
S106：网络设备将第一资源的分配信息发送给远端用户设备，使得远端用户设备在第一资源上将数据发送给中继用户设备；
S108：网络设备将第二资源的分配信息发送给中继用户设备，使得中继用户设备在第二资源上将数据发送给网络设备。
在本公开实施例中，远端用户设备发送的第一BSR可以请求远端用户设备到中继用户设备数据传输的第一资源以及中继用户设备到网络设备数据传输的第二资源，实现了远端用户设备不仅可以请求自己传输数据所需的第一资源，还可以请求中继用户设备传输数据所需的第二资源，不需要远端用户设备和中继用户设备分别请求各自所需的资源，从而提高了资源获取效率。
在本公开的一个实施例中，如图4所示，第一BSR的格式可包括以下的域的组合：
1)中继用户设备的标识(Relay UE ID)，例如小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)，目标用户设备标 识(destination UE ID)等。
2)从中继用户设备到网络设备的逻辑信道的标识(Logical Channel Identifier，LCID)，即图4中的第一逻辑信道标识(LCID 1)。或者，从中继用户设备到网络设备的逻辑信道组的标识(Logical Channel Group Identifier，LCG ID)，即图4中的第一逻辑信道组标识(LCG ID 1)。这里的LCID 1或者LCG ID 1指Uu LCID，用于标示relay UE到网络设备的逻辑信道或逻辑信道组。
3)从远端用户设备到中继用户设备的逻辑信道的标识，即图4中的第二逻辑信道标识(LCID 1)。或者，从远端用户设备到中继用户设备的逻辑信道组的标识，即图4中的第二逻辑信道组标识(LCG ID 2)。这里的LCID 2或者LCG ID 2指Sidelink LCID，主要用于标示remote UE到relay UE的Sidelink的逻辑信道或逻辑信道组。
4)从中继用户设备到网络设备的缓存大小等级，即图4中的第一缓存大小等级(Buffer Size level 1)，这里的Buffer Size 1指Uu Buffer Size。
5)从远端用户设备到中继用户设备的缓存大小等级或授权大小等级，即图4中的第二缓存大小等级(Buffer Size level 2)或授权大小等级(Grant size level)，这里的Buffer Size level 2指Sidelink Buffer Size level，Grant size level指Sidelink Grant size level。
其中，第一BSR的格式包括的域的顺序并不限于图4示出的顺序。
在本公开的一个实施例中，第一BSR的头格式中可使用第一逻辑信道标识值标示第一BSR的类型，或者可使用第二逻辑信道标识值和预留比特位值标示第一BSR的类型。
下面通过一个例子说明第一BSR的头格式。比如，第一BSR的头格式中使用不同于现有技术中的逻辑信道标识值(例如选取NR UL-SCH reserved LCID values 33-51中的某一个值40)标示第一BSR的类型，或者，第一BSR的头格式中使用现有技术的逻辑信道标识值(例如选取与NR Long BSR的LCID value 62的相同值)和预留R比特位值标示第一BSR的类型。
在本公开的一个实施例中，资源请求方法还包括：向所述网络设备发 送第二BSR，所述第二BSR用于向所述网络设备请求第一资源，所述第一资源是所述远端用户设备到所述中继用户设备数据传输的资源。
下面结合图5说明本公开实施例，图5示出了根据本公开另一个实施例的资源请求方法的时序图。如图5所示，资源请求方法包括：
S202：远端用户设备向网络设备发送第一BSR和第二BSR，第一BSR用于向网络设备请求第二资源，第二BSR用于向网络设备请求第一资源，第一资源是用于远端用户设备到中继用户设备数据传输的资源，第二资源是用于中继用户设备到网络设备数据传输的资源。
S204：网络设备接收第一BSR和第二BSR，根据第一BSR分配第一资源，根据第二BSR分配第二资源。
S206：网络设备将第一资源的分配信息发送给远端用户设备。
S208：网络设备将第二资源的分配信息发送给中继用户设备。
在本公开实施例中，若远端用户设备有上行数据待发送，可以发送第一BSR和第二BSR，第一BSR请求远端用户设备到中继用户设备数据传输的第二资源，第二BSR请求中继用户设备到网络设备数据传输的第一资源。因此，远端用户设备不仅可以请求自己传输数据所需的第一资源，还可以请求中继用户设备传输数据所需的第二资源，不需要远端用户设备和中继用户设备分别请求各自所需的资源，从而提高了资源获取效率。
在本公开的一个实施例中，如图6所示，第一BSR的格式可包括以下的域的组合：
1)中继用户设备的标识(Relay UE ID)，例如C-RNTI，destination UE ID等。
2)从中继用户设备到网络设备的逻辑信道的标识或者从中继用户设备到网络设备的逻辑信道组的标识；
3)从中继用户设备到网络设备的缓存大小等级。
其中，第一BSR的格式包括的域的顺序并不限于图6示出的顺序。
在本公开的一个实施例中，第一BSR的头格式中使用第一逻辑信道标识值标示第一BSR的类型，或者使用第二逻辑信道标识值和预留比特位值标示第一BSR的类型。
下面通过一个例子说明第一BSR的头格式。比如，第一BSR的头格式中使用不同于现有技术中的逻辑信道标识值(例如选取NR UL-SCH reserved LCID values 33-51中的某一个值40)标示第一BSR的类型，或者，第一BSR的头格式中使用现有技术的逻辑信道标识值(例如选取与NR Long BSR的LCID value 62的相同值)和预留R比特位值标示第一BSR的类型。
在本公开的一个实施例中，比如图2、图3或图5的实施例中，资源请求方法还可包括：
网络设备向远端用户设备发送通知信息，通知信息用于通知远端用户设备已分配第二资源，以使远端用户设备接收网络设备发送的通知信息。即由网络设备通知远端用户设备：网络设备为中继用户设备分配了第二资源。
在本公开的一个实施例中，中继用户设备在接收到网络设备分配的第二资源的信息之后，资源请求方法还可包括：
中继用户设备向远端用户设备发送通知信息，通知信息用于通知远端用户设备已分配第二资源，以使远端用户设备接收中继用户设备发送的通知信息。即由中继用户设备通知远端用户设备：网络设备为中继用户设备分配了第二资源。
在本公开的一个实施例中，在远端用户设备接收网络设备或中继用户设备发送的通知信息之后，资源请求方法还可包括：
若远端用户设备有已触发的第一BSR，并且已触发的第一BSR未被取消发送，则远端用户设备启动或重启重传BSR定时器。
在本公开的一个实施例中，资源请求方法还包括：
若远端用户设备有待转发的上行数据，且重传BSR定时器计时超时，说明满足重传BSR的条件，则远端用户设备触发第一BSR进行重传。
在本公开的一个实施例中，资源请求方法还可包括：
若远端用户设备满足取消BSR的条件，则执行以下至少一项：取消已触发的第一BSR的发送，停止重传BSR定时器，停止周期性BSR定时器。
其中，取消BSR的条件包括以下条件中的至少一项：中继用户设备重 选，停止中继操作，从中继通信模式切换到非中继通信模式。
其中，中继用户设备重选包括以下的至少一项：对Sidelink测量的结果低于门限值导致的中继用户设备重选，由于上层原因导致的中继用户设备重选，中继用户设备停止为远端用户设备提供服务导致的中继用户设备重选。
停止中继操作包括：终止与网络设备的通信，或者，不通过中继用户设备而直接与网络设备通信。
图7示出了根据本公开一个实施例的通信场景的示意图，图2或图3或图5的实施例可以应用到该通信场景中。如图7所示，remote UE(即远端用户设备)和relay UE(即中继用户设备)在网络设备的信号覆盖范围内。remote UE通过PC5空口(对应Sidelink)连接到relay UE，relay UE通过Uu空口(对应上行Uplink+下行Downlink)连接到网络设备。
其中：1)remote UE和relay UE均处于无线资源控制(Radio Resource Control，RRC)连接态；2)remote UE的上行数据通过relay UE转发给网络设备。
LTE Sidelink的设计适用于特定的公共安全事务(如火灾场所或地震等灾难场所进行紧急通讯)，或车联网(vehicle to everything，V2X)通信等。车联网通信包括各种业务，例如，基本安全类通信，高级(自动)驾驶，编队，传感器扩展等等。由于LTE Sidelink支持广播通信，因此主要用于基本安全类通信，其他在时延、可靠性等方面具有严格服务质量(Quality of Service，QoS)需求的高级V2X业务将通过新空口(New Radio，NR)Sidelink支持。
