背景技术
当前，业界对在蜂窝网络中使用无人驾驶飞行器(Unmanned Aerial Vehicle，UAV，也称为无人机)越来越感兴趣。无人机的商业运用场景也在快速增长，比如搜寻和救助、关键基础设施监控、野生动植物保护、飞行摄像机、监控等，这些应用场景在未来几年都会快速增加。无人机不同于普通的地面上的用户设备(User Equipment,UE)，比如无人机的飞行高度和速度要远大于地面上的普通UE。当无人机的飞行高度较低(相对于基站)时，无人机可以看作普通的UE。
然而，当无人机的飞行高度较高(例如高于基站)时，由于高空电磁信号衰减较小，因此来自无人机的上行信号会被更多的小区收到，无人机也会收到来自更多的小区的下行信号，从而有可能引起干扰。

1.问题的描述；

3.上行干扰场景基站侧的配置示例；
4.方法实施例；
5.应用示例。
<1.问题的描述>
图1是示出根据本公开的实施例的下行干扰场景的示意图。如图1所示，在无线通信系统中，蜂窝小区A的一跳邻小区包括：a1、a2、a3、a4、a5和a6。这里，蜂窝小区A的一跳邻小区也称为蜂窝小区A的邻小区。在本公开中，蜂窝小区A的邻小区指的是蜂窝小区A的一跳邻小区，即地理位置与蜂窝小区A相邻的小区。在图1中，蜂窝小区A的两跳邻小区包括：b1、b2、…、b12。在本公开中，蜂窝小区A的两跳或者更多跳邻小区称为除蜂窝小区A的邻小区以外的其它小区。此外，该无线通信系统还包括无人机设备UAV。这里，假定无人机设备UAV的当前服务小区是蜂窝小区A，而当无人机设备UAV高度达到一定阈值时由于距离蜂窝小区b6的基站较近或者与蜂窝小区b6的基站的链路质量较好从而能够接收到来自蜂窝小区b6的下行信息。在这种情况下，无人机设备UAV能够同时接收到蜂窝小区A的基站和蜂窝小区b6的基站的下行信息，如果蜂窝小区A的基站和蜂窝小区b6的基站采用相同的资源来发送下行信息，那么来自蜂窝小区A的基站的信息和来自蜂窝小区b6的基站的信息相对于彼此都可以看作是干扰信息，从而导致无人机设备UAV不能正确解调来自任何一方的信息。由此可见，在图1所示的场景中，无人机设备能够接收到来自多个基站设备的下行信息，并且多个基站设备采用相同的资源来发送下行信息，因此这样的场景在本文中被称为下行干扰场景。
值得注意的是，在图1所示的无线通信系统中仅示出了一个无人机设备，但是本公开并不限于此，无线通信系统中可能包括多个无人机设备。进一步，在图1所示的无线通信系统中仅示出了蜂窝小区A的一跳邻小区和两跳邻小区，蜂窝小区A还可以有多于两跳的邻小区。此外，对无人机设备造成干扰的基站可以是两个，也可以是更多个，并且这些基站所在的小区可以互为一跳邻小区、两跳邻小区或者更多跳邻小区。也就是说， 本公开并不限于图1所示的下行干扰场景，本公开适用于在无人机设备处受到来自多个基站设备的下行信息干扰的所有无线通信系统。
图2是示出根据本公开的实施例的上行干扰场景的示意图。图2所示的蜂窝小区的设置与图1相同，在此不再赘述。此外，该无线通信系统还包括无人机设备UAV1和UAV2。这里，假定无人机设备UAV1的当前服务小区是蜂窝小区b7，无人机设备UAV2的当前服务小区是蜂窝小区b9。而当无人机设备UAV1和UAV2高度达到一定阈值时，由于距离蜂窝小区A的基站较近或者与蜂窝小区A的基站的链路质量较好，从而使得蜂窝小区A的基站能够接收到来自无人机设备UAV1和UAV2的信息。在这种情况下，蜂窝小区A的基站能够同时接收到无人机设备UAV1和UAV2的上行信息，如果无人机设备UAV1和UAV2采用相同的资源来发送上行信息，那么来自无人机设备UAV1的信息和来自无人机设备UAV2的信息相对于彼此都可以看作是干扰信息，从而导致蜂窝小区A的基站不能正确解调来自任何一方的信息。由此可见，在图2所示的场景中，基站能够接收到来自多个无人机设备的上行信息，并且多个无人机设备采用相同的资源来发送上行信息，因此这样的场景在本文中被称为上行干扰场景。
值得注意的是，在图2所示的无线通信系统中仅示出了两个无人机设备，但是本公开并不限于此，无线通信系统中可能包括更多个无人机设备。进一步，在图2所示的无线通信系统中仅示出了蜂窝小区A的一跳邻小区和两跳邻小区，蜂窝小区A还可以有多于两跳的邻小区。此外，对基站造成干扰的无人机设备可以是两个，也可以是更多个，并且无人机设备可以来自基站所在的小区的一跳邻小区、两跳邻小区或者更多跳邻小区。也就是说，本公开并不限于图2所示的上行干扰场景，本公开适用于在基站设备处受到来自多个无人机设备的上行信息干扰的所有无线通信系统。
此外，在本公开中，造成干扰的信息可以包括数据信息和控制信息。控制信息可以包括参考信号(Reference Signal,RS)。这里的参考信号包括但不限于SRS(Sounding reference signals，探测参考信号)、CRS(Cell-specific reference signals，小区参考信号)和CSI-RS(Channel State Information Reference Signal，信道状态信息参考信号)等。
图3是示出根据本公开的实施例的用于发送参考信号的资源的示意图。这里，图3仅仅以CRS为例说明了发送信息的资源的配置。这里， 图3示出了发送CRS的六种资源配置，分别为“偏移＝0”的配置、“偏移＝1”的配置、“偏移＝2”的配置、“偏移＝3”的配置、“偏移＝4”的配置和“偏移＝5”的配置。其中，横轴代表时域，纵轴代表频域，每个小方块代表一个RE(Resource Element，资源元素)，在每种配置中示出了时域上一个子帧(14个OFDM符号)，频域上12个子载波(即1个RB(Resource Block，资源块)占用的频谱资源)的资源配置情况。以“偏移＝0”的配置为例，每个子帧包括两个时隙，在每个时隙中的第1和4个OFDM符号上的两个子载波上发送CRS(黑色方块示出了发送CRS的RE)。对于其它偏移的配置是类似的。如图3所示，对于不同的配置，在频域上采用不同的子载波上发送CRS，而在时域上每个子帧的每个时隙都要发送CRS。因此，如果多个基站采用相同的配置方式(例如都采用“偏移＝0”的配置)发送CRS，那么如果无人机设备能够同时接收到这多个基站的信号，则在无人机设备处会产生下行干扰。
如上所述，图3以CRS为例对发送控制信息产生下行干扰的资源配置方式进行了说明。当然，对于由其它控制信息产生下行干扰以及由控制信息产生上行干扰的原理是类似的。进一步，由数据信息产生下行干扰和上行干扰的原理也是类似的。即，在无人机设备处收到来自多个基站设备采用相同的资源发送的下行信息会造成下行干扰，或者在基站处收到来自多个无人机设备采用相同的资源发送的上行信息会造成上行干扰。这里的资源可以包括频谱资源。
图4示出了根据本公开的实施例的造成上行和下行干扰的信息发送的示意图。图4上半部分示出了造成下行干扰的信息发送的示意图，图4的下半部分示出了造成上行干扰的信息发送的示意图。如图4所示，当蜂窝小区A的基站和蜂窝小区b6的基站采用相同的资源，例如相同的频率资源来发送下行信息时，由于蜂窝小区A的基站和蜂窝小区b6的基站在时间上会持续发送下行信息(例如在每个子帧的每个时隙都要发送CRS)，从而导致图1中所述的UAV能够同时接收到来自这两个基站的下行信息，不能正确解调来自任何一方的信息。类似地，如图4所示，当UAV1和UAV2采用相同的资源，例如相同的频率资源来发送上行信息时，由于UAV1和UAV2在时间上会持续发送上行信息，从而导致图2中所述的蜂窝小区A的基站能够同时接收到来自UAV1和UAV2的上行信息，不能正确解调来自任何一方的信息。
本公开针对以上场景提出了一种无线通信系统中的电子设备、由无 线通信系统中的电子设备执行的无线通信方法以及计算机可读存储介质，以解决包括无人机设备的无线通信系统中产生的干扰问题。
<2.下行干扰场景基站侧的配置示例>
图5是示出根据本公开的实施例的电子设备400的结构的框图。这里的电子设备400可以是无线通信系统中的基站设备，该无线通信系统可以包括多个基站设备以及一个或多个无人机设备。如图5所示，电子设备400可以包括生成单元410和收发单元420。
这里，电子设备400的各个单元都可以包括在处理电路中。需要说明的是，电子设备400既可以包括一个处理电路，也可以包括多个处理电路。进一步，处理电路可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是，这些功能单元可以是物理实体或逻辑实体，并且不同称谓的单元可能由同一个物理实体实现。
根据本公开的实施例，生成单元410可以根据用户设备受到的干扰情况生成资源配置信息，用户设备的当前高度高于高度阈值。
根据本公开的实施例，电子设备400可以为用户设备的当前服务小区的基站设备，而用户设备可以是无人机设备。前文中提到，当无人机的飞行高度较低(相对于基站)时，无人机设备可以看作一般的UE；而当无人机的飞行高度较高(例如高于基站)时，由于高空电磁信号衰减较小，无人机设备不可以看作一般的UE。因此，在本公开中，高度阈值可以是确定能否将无人机设备看作一般的UE的阈值。也就是说，当用户设备的当前高度高于高度阈值时，该用户设备不能被看作是一般的UE。
根据本公开的实施例，收发单元420可以向除了用户设备的当前服务小区的邻小区以外的其它小区的基站设备发送资源配置信息，以用于其它小区的基站设备配置用于发送信息的资源。
根据本公开的实施例，用户设备的当前服务小区可以是电子设备400作为基站设备的小区。进一步，当前服务小区的邻小区指的是当前服务小区的一跳邻小区，即地理位置与当前服务小区相邻的小区。也就是说，除当前服务小区的邻小区以外的其它小区是当前服务小区的两跳邻小区或更多跳邻小区。根据本公开的实施例，收发单元420可以向这些其它小区发送用于其它小区的基站设备配置用于发送信息的资源的资源配置信息。
由此可见，根据本公开的实施例，电子设备可以向除邻小区以外的 其它小区的基站设备发送资源配置信息。对于一般的UE来说，当其位于小区边缘时，可能会接收到来自两个基站设备的下行信号。也就是说，对UE造成干扰的基站设备来自邻小区。因此，在传统的干扰协调方案中，基站设备只能向邻小区的基站设备发送用于协调资源的信息。而在本公开的实施例中，基站设备可以向除邻小区之外的小区的基站设备发送用于协调资源的资源配置信息，从而可以解决在包括无人机的无线通信系统中的下行干扰问题。
根据本公开的实施例，电子设备400还可以包括干扰确定单元430。干扰确定单元430可以根据电子设备400、邻小区的基站设备和其它小区的基站设备用于发送信息的资源确定用户设备受到的干扰情况。
根据本公开的实施例，电子设备400发送的信息、邻小区的基站设备发送的信息以及其它小区的基站设备发送的信息都可以包括数据信息和控制信息。控制信息还可以包括参考信号。也就是说，当电子设备400希望确定用户设备针对数据信息受到的干扰情况时，可以根据电子设备400、邻小区的基站设备和其它小区的基站设备用于发送数据信息的资源来确定；当电子设备400希望确定用户设备针对控制信息受到的干扰情况时，可以根据电子设备400、邻小区的基站设备和其它小区的基站设备用于发送控制信息的资源来确定。
根据本公开的实施例，当电子设备400、邻小区的基站设备以及其它小区的基站设备中的多个基站设备用于发送信息的资源有交叠时，干扰确定单元430可以确定用户设备受到干扰。这里，用于发送信息的资源可以包括用于发送信息的频谱资源。如前文中所述，当多个基站设备用于发送信息的频谱资源相同时，干扰确定单元430可以确定用户设备受到干扰。例如，在图3所示的示例中，当多个基站设备都采用“偏移＝0”的配置来发送CRS时，这些基站设备用于发送CRS的频谱资源相同，干扰确定单元430此时可以确定用户设备针对控制信息CRS受到了干扰。
根据本公开的实施例，电子设备400可以知晓电子设备400用于发送信息的资源。也就是说，电子设备400的干扰确定单元430还需要获取邻小区的基站设备以及其它小区的基站设备用于发送信息的资源。下面将介绍几种电子设备400获取邻小区的基站设备以及其它小区的基站设备用于发送信息的资源的方式。
根据本公开的实施例，电子设备400可以通过X2接口获取邻小区的基站设备和其它小区的基站设备用于发送信息的资源。这里，电子设备 400、邻小区的基站设备以及其它小区的基站设备中的每个设备可以通过X2接口向所述设备所在的小区的邻小区发送信息，以告知所述设备所知晓的所有基站设备用于发送信息的资源。也就是说，针对以上每个设备，每次获知了新的设备用于发送信息的资源时，就通过X2接口向所在小区的邻小区发送信息，以告知邻小区其获知的新的设备用于发送信息的资源。
图6是示出根据本公开的实施例的通过X2接口获取所有基站设备用于发送信息的资源的信令流程图。如图6所示，基站1、基站2和基站3都是无线通信系统中的基站设备，其中基站1所在的小区与基站2所在的小区属于邻小区，基站2所在的小区与基站3所在的小区属于邻小区，而基站1所在的小区和基站3所在的小区不是邻小区。在步骤S501中，基站1、基站2和基站3中的每个基站都通过X2接口向所在小区的邻小区发送该基站用于发送信息的资源。即，基站2向基站1和基站3发送基站2用于发送信息的资源，基站1向基站2发送基站1用于发送信息的资源，并且基站3向基站2发送基站3用于发送信息的资源。接下来，在步骤S502中，由于基站1、基站2和基站3都收到来自其它基站用于发送信息的资源，从而使得每个基站都通过X2接口向所在小区的邻小区发送自己获知的所有基站用于发送信息的资源。即，基站1向基站2发送基站1和基站2用于发送信息的资源，基站2向基站1发送基站2和基站3用于发送信息的资源，基站2向基站3发送基站1和基站2用于发送信息的资源，并且基站3向基站2发送基站2和基站3用于发送信息的资源。如图6所示，以这种方式，基站1可以获知基站2和基站3用于发送信息的资源，基站2可以获知基站1和基站3用于发送信息的资源，基站3可以获知基站1和基站2用于发送信息的资源。
由此可见，根据本公开的实施例，由于X2接口只能在邻小区的基站之间传递信息，因此通过多次传递的方式可以使得无线通信系统中的任意一个基站能够获知无线通信系统中的所有基站用于发送信息的资源。
根据本公开的实施例，电子设备400还可以通过S1接口获取邻小区的基站设备和其它小区的基站设备用于发送信息的资源。这里，电子设备400可以通过S1接口从核心网中的MME(Mobility Management Entity，移动管理实体)获取邻小区的基站设备和其它小区的基站设备用于发送信息的资源。根据本公开的实施例，电子设备400可以通过S1接口向MME上报电子设备400用于发送信息的资源。这种上报可以是周期性的也可以 是事件性触发的。这样一来，无线通信系统中的所有基站设备都通过S1接口向MME上报其用于发送信息的资源，当电子设备400需要获取所有基站设备用于发送信息的资源时，通过S1接口从MME获取即可。
由此可见，根据本公开的实施例，基站可以通过S1接口直接从MME获取信息，使得获取的步骤简单易行，节约时间和信令开销。
根据本公开的实施例，电子设备400通过X2接口或S1接口获取邻小区的基站设备和其它小区的基站设备用于发送信息的资源的过程可以是周期性触发的。也就是说，以一定的时间间隔，电子设备400周期性通过X2接口或S1接口获取邻小区的基站设备和其它小区的基站设备用于发送信息的资源。电子设备400在确定用户设备受到的干扰情况时使用最新获取的结果即可。
此外，对于控制信息，基站用于发送控制信息的资源可能与基站的一个或多个参数呈对应关系。例如，基站用于发送CRS的资源与基站的PCI(Physical Cell Identifier，物理小区标识)呈对应关系。在这种情况下，电子设备400可以通过邻小区的基站设备和其它小区的基站设备的参数来获取邻小区的基站设备和其它小区的基站设备用于发送信息的资源。邻小区的基站设备和其它小区的基站设备的参数可以预先存储在电子设备400中，也可以由电子设备400通过S1接口从MME一次性获取，无需更新。
根据本公开的实施例，可以用各种形式来表示用于发送信息的资源，例如用于发送信息的频谱资源的编号(编号与频谱资源有一一对应的关系)等。在表示用于发送控制信息的资源时，一般来说发送控制信息的资源只有几种固定的配置，在这种情况下还可以用配置的编号来表示用于发送控制信息的资源。在图3所示的示例中，可以用编号0-5来表示用于发送CRS的资源。例如，当其它基站设备用编号0来表示用于发送CRS的资源时，电子设备400可以确定该其它基站设备采用偏移＝0的配置来发送CRS，从而可以确定该其它基站设备用于发送CRS的资源。此外，在基站设备用于发送控制信息的资源与基站设备的一个或多个参数呈对应关系的情况下，还可以用基站设备的参数来表示用于发送控制信息的资源。例如，电子设备400获知了某个基站设备的PCI，则可以根据PCI来确定该基站设备用于发送控制信息的资源。
由此可见，根据本公开的实施例，干扰确定单元430可以根据电子设备、邻小区的基站设备和其它小区的基站设备的PCI确定电子设备、 邻小区的基站设备和其它小区的基站设备发送控制信息的资源。
如上所述，根据本公开的实施例，电子设备400可以通过各种实施方式确定电子设备400、邻小区的基站设备和其它小区的基站设备用于发送信息的资源，从而确定电子设备400覆盖范围内的用户设备是否受到了干扰。
根据本公开的实施例，干扰确定单元430还可以根据用户设备的位置信息确定用户设备受到的干扰情况。
根据本公开的实施例，电子设备400覆盖范围内的用户设备都可以周期性上报自己的位置，从而使得电子设备400可以获取其覆盖范围内所有用户设备的位置信息。
根据本公开的实施例，由于用户设备仅仅能够收到无线通信系统中的部分基站设备的信号，例如用户设备能够收到距离自己较近的基站设备的信号，用户设备能够收到与自己之间的链路状况较好的基站设备的信号等等，因此，电子设备400在确定用户设备是否受到了干扰时还可以考虑用户设备的位置信息。
根据本公开的实施例，干扰确定单元430可以根据电子设备400、邻小区的基站设备和其它小区的基站设备中距离用户设备小于距离阈值的基站设备用于发送信息的资源来确定该用户设备受到的干扰情况。
根据本公开的实施例，干扰确定单元430还可以综合考虑用户设备的位置信息以及用户设备距离基站设备的链路质量等信息，从而从电子设备400、邻小区的基站设备和其它小区的基站设备中选取部分基站设备，根据部分基站设备用于发送信息的资源来确定该用户设备受到的干扰情况。这里，选取部分基站设备的原则是使得选取的基站设备发送的下行信号可能到达用户设备，也就是说，这部分基站设备是用户设备的潜在干扰源。
由此可见，根据本公开的实施例，电子设备400在确定用户设备受到的干扰情况时，可以仅考虑部分基站设备，能够简化流程，减小信令开销，避免对过多的基站设备造成影响。
根据本公开的实施例，干扰确定单元430可以根据电子设备400、邻小区的基站设备和其它小区的基站设备发送信息的资源对电子设备400、邻小区的基站设备和其它小区的基站设备进行分组。
这里，如果干扰确定单元430没有从无线通信系统的所有基站设备 中选取部分基站设备用于确定该用户设备受到的干扰情况，那么干扰确定单元430可以根据电子设备400、邻小区的基站设备和其它小区的基站设备(实际上就是无线通信系统中的所有基站设备)发送信息的资源对电子设备400、邻小区的基站设备和其它小区的基站设备进行分组。如果干扰确定单元430从无线通信系统的所有基站设备中选取部分基站设备用于确定该用户设备受到的干扰情况，那么干扰确定单元430可以根据这部分基站设备发送信息的资源对部分基站设备进行分组。
根据本公开的实施例，干扰确定单元430可以对上述设备进行分组，以使得同一组中的设备用于发送信息的资源相同。这里的资源可以包括频谱资源。
以图1所示的场景为例，假定干扰确定单元430根据无人机设备UAV的地理位置确定蜂窝小区A、a1、a2、b6和b7的基站设备是无人机设备UAV的潜在干扰基站，即这些蜂窝小区的基站设备距离无人机设备UAV较近或者这些蜂窝小区的基站设备与无人机设备UAV之间的链路质量较好，那么干扰确定单元430可以对这五个蜂窝小区进行分组。这里，假定蜂窝小区A的基站设备使用编号为1的频谱资源发送信息，蜂窝小区a1的基站设备使用编号为2的频谱资源发送信息，蜂窝小区a2的基站设备使用编号为3的频谱资源发送信息，蜂窝小区b6的基站设备使用编号为1的频谱资源发送信息，蜂窝小区b7的基站设备使用编号为3的频谱资源发送信息，从而干扰确定单元430可以对这五个蜂窝小区的基站设备进行分组如下：
第一组(使用编号为1的频谱资源)：蜂窝小区A的基站设备；蜂窝小
区b6的基站设备；
第二组(使用编号为2的频谱资源)：蜂窝小区a1的基站设备；
第三组(使用编号为3的频谱资源)：蜂窝小区a2的基站设备；蜂窝
小区b7的基站设备。
根据本公开的实施例，干扰确定单元430可以根据分组情况确定用户设备受到的干扰情况。具体地，如果任何一个分组中包括多个设备，则干扰确定单元430可以确定用户设备受到干扰。反之，如果所有分组中都只有一个设备，则干扰确定单元430可以确定用户设备没有受到干扰。
根据本公开的实施例，在确定用户设备受到干扰时，生成单元410可以生成资源配置信息，收发单元420可以向邻小区的基站设备以及除邻 小区以外的其它小区的基站设备发送资源配置信息。具体地，收发单元430可以向以下基站设备发送资源配置信息：该基站设备位于包括多个设备的分组中。在上文所述的示例中，第一组和第三组包括多个设备，则电子设备400可以向蜂窝小区b6的基站设备、蜂窝小区a2的基站设备和蜂窝小区b7的基站设备发送资源配置信息。
如上所述，根据本公开的实施例，当某组中包括多个基站设备时，说明这多个基站设备使用相同的资源发送下行信息，用户设备可能会接收到这多个基站设备的下行信息，从而造成干扰。在这种情况下，电子设备400可以针对这些基站设备生成资源配置信息并向这些基站设备发送，以协调发送下行信息的资源，从而解决干扰问题。此外，由于其它基站设备(蜂窝小区b6的基站设备)与用户设备的当前服务小区的基站设备(蜂窝小区A的基站设备)最有可能对用户设备造成干扰，而在现有的蜂窝网络中可以避免邻小区之间的干扰，因此在一般情况下，与当前服务小区的基站设备使用相同资源的基站设备是除邻小区以外的小区的基站设备。因此，根据本公开的实施例，电子设备400可以仅仅向除邻小区之外的其它小区的基站设备发送资源配置信息。当然，在一些情况下，也会存在多个非当前服务小区的基站设备对用户设备造成干扰的情况(例如蜂窝小区a2的基站设备和蜂窝小区b7的基站设备)，这多个非当前服务小区很可能是当前服务小区的邻小区，因此电子设备400也可以向邻小区的基站设备发送资源配置信息。
根据本公开的实施例，电子设备400可以通过X2接口或者S1接口发送资源配置信息。例如，电子设备400可以通过S1接口向MME发送资源配置信息，以使得其它基站设备也可以通过S1接口从MME获取自己的资源配置信息。当然，如果接收资源配置信息的基站设备是电子设备400所在小区的邻小区的基站设备，那么电子设备400也可以通过X2接口发送资源配置信息，本公开对此不做限定。
根据本公开的实施例，生成单元410在生成资源配置信息时，可以使得位于同一组的设备对发送信息的资源进行复用。
根据本公开的实施例，当某个组包括多个设备时，由于这多个设备使用相同的资源发送信息，因此需要多个设备对这相同的资源进行复用，以解决干扰问题。当某个组包括一个设备时，由于复用的主体只有一个，因此该设备可以继续按照原来的方式使用原有的资源来发送信息，即无需针对该设备生成资源配置信息。
根据本公开的实施例，复用的方式可以包括时分复用、频分复用和空分复用。下面将详细介绍这三种复用方式。
当同一组中的多个设备对发送信息的资源进行时分复用时，这多个设备可以周期性地使用上述发送信息的资源，以使得不同的设备使用资源的时间不同。生成单元410可以生成资源配置信息，例如可以包括使用资源的周期和开始的时间等参数。
图7是示出根据本公开的实施例的对同一组基站设备的发送信息的资源进行时分复用的示意图。这里，图7以CRS为例示出了两个基站设备对发送信息的资源进行时分复用的示意图。如图7所示，示出了在时域上包括四个子帧和在频域上包括24个子载波(即两个RB所占用的频谱)的资源使用情况。这里假定两个基站设备都使用偏移＝0的配置来发送CRS。在采用了时分复用之后，充满了向左倾斜的条纹的方块表示第一个基站设备发送CRS的RE，充满了向右倾斜的条纹的方块表示第二个基站设备发送CRS的RE。由此可见，两个基站设备都以两个子帧为周期来发送CRS，两个基站设备的开始时间不同，其中，第一个基站设备从第一个子帧开始以两个子帧为周期来发送CRS，第二个基站设备从第二个子帧开始以两个子帧为周期来发送CRS。在频域上，两个基站设备使用了相同的频谱资源来发送CRS。这样一来，两个基站设备发送CRS的时间不同，使得用户设备不会同时接收到来自两个基站设备的CRS，从而避免干扰。
值得注意的是，图7仅仅示出了两个基站设备发送CRS的情况，对于除CRS以外的控制信息以及数据信息的发送，以及更多个基站设备的情况也是类似的，在此不再赘述。
当同一组中的多个设备对发送信息的资源进行频分复用时，这多个设备可以通过不同的频谱资源来使用上述发送信息的资源。生成单元410可以生成资源配置信息，例如可以包括频谱资源的编号等信息。
图8是示出根据本公开的实施例的对同一组基站设备的发送信息的资源进行频分复用的示意图。这里，图8以CRS为例示出了两个基站设备对发送信息的资源进行频分复用的示意图。如图8所示，示出了在时域上包括四个子帧和在频域上包括24个子载波(即两个RB所占用的频谱)的资源使用情况。这里假定两个基站设备都使用“偏移＝0”的配置来发送CRS。在采用了频分复用之后，充满了向左倾斜的条纹的方块表示第一个基站设备发送CRS的RE，充满了向右倾斜的条纹的方块表示第二个基 站设备发送CRS的RE。由此可见，两个基站设备使用的频谱资源不同，第一个基站设备使用图8上部的频谱资源，第二个基站设备使用图8下部的频谱资源。而在时域上，两个基站设备使用的时域资源都是相同的，即在每个子帧的每个时隙都发送CRS。这样一来，两个基站设备发送CRS的频谱资源不同，使得用户设备不会在同一个频谱资源上接收到来自两个基站设备的CRS，从而避免干扰。
值得注意的是，图8仅仅示出了两个基站设备发送CRS的情况，对于除CRS以外的控制信息以及数据信息的发送，以及更多个基站设备的情况也是类似的，在此不再赘述。
当同一组中的多个设备对发送信息的资源进行空分复用时，这多个设备可以使用不同方向的波束来使用发送信息的资源，以使得不同的设备发送的波束不同。生成单元410可以生成资源配置信息，例如可以包括波束编号和方向等信息。
图9是示出根据本公开的实施例的对同一组基站设备的发送信息的资源进行空分复用的示意图。如图9所示，假定基站1和基站2都使用相同的资源向无人机设备发送下行信息。当进行空分复用后，两个基站对下行信息进行波束赋形，从而使用不同方向的波束来发送信息，而这两个基站设备在频域上还是使用相同的资源，在时域上也是全时段使用。这样一来，用户设备在接收下行信息时根据波束方向可以确定发送的基站设备，从而避免干扰。
如上详述了对同一组中的基站设备进行复用的各个实施例，当然，在本公开中，复用的方式并不限于时分复用、频分复用和空分复用，只要能对发送信息的资源进行复用以使得用户设备能够正确接收信息并避免干扰即可。
根据本公开的实施例，在针对控制信息的情况下，生成单元410还可以根据邻小区的基站设备以及除邻小区以外的其它小区的基站设备是否为其它无人机设备服务来生成资源配置信息。具体地，当某组中包括多个设备，并且这多个设备中的一个或多个设备没有为任何无人机设备提供服务时，生成单元410可以为这一个或多个设备生成资源配置信息，以使得这一个或多个设备不发送任何控制信息，例如参考信号。例如，为这一个或多个设备生成的资源配置信息可以包括用于使其不发送控制信息的信令。进一步，生成单元410可以针对该组中除这一个或多个设备以外的设备生成资源配置信息，以使得该组中除这一个或多个设备以外的设备对 发送信息的资源进行复用。
以前文中所述的示例为例，假定在第一组(使用编号为1的频谱资源)中，蜂窝小区b6的基站设备没有为任何无人机设备提供服务，那么生成单元410可以针对蜂窝小区b6的基站设备生成资源配置信息，以使得蜂窝小区b6的基站设备不发送任何控制信息，而蜂窝小区A的基站设备则可以继续使用编号为1的频谱资源。这里，如果除去蜂窝小区b6的基站设备以外第一组中还包括多个设备，那么这多个设备可以根据本公开的各个实施例对编号为1的频谱资源进行复用。
如上所述，根据本公开的实施例，当基站设备没有为无人机设备提供服务时，可以生成资源配置信息以“关闭”该基站设备，从而使得复用的基站设备的数目减少，在避免干扰的情况下提高复用的效果。
下面将以一个具体的实施例来说明前文中所述的资源复用方式。图10是示出根据本公开的实施例的对基站设备进行分组的示意图。如图10所示，蜂窝小区A、a1、a2、b6和b7的基站设备是无人机设备UAV的潜在干扰基站，并且干扰确定单元430可以对这五个蜂窝小区进行分组如下：第一组(使用编号为1的频谱资源)：蜂窝小区A的基站设备；蜂窝小区b6的基站设备；第二组(使用编号为2的频谱资源)：蜂窝小区a1的基站设备；第三组(使用编号为3的频谱资源)：蜂窝小区a2的基站设备；蜂窝小区b7的基站设备。
图11是示出根据本公开的实施例的对图10中的每组基站设备的发送信息的资源进行时分复用的示意图。如图11所示，在第一组中，假定蜂窝小区b6的基站设备没有为任何无人机设备提供服务，那么生成单元410可以针对蜂窝小区b6的基站设备生成资源配置信息，以使得蜂窝小区b6的基站设备不发送任何控制信息，而蜂窝小区A的基站设备则可以继续使用编号为1的频谱资源。也就是说，蜂窝小区A的基站设备可以一直使用编号为1的频谱资源发送信息，蜂窝小区b6的基站设备不能使用编号为1的频谱资源发送信息，即处于“关闭”状态。在第二组中，由于只有一个蜂窝小区的基站设备，因此蜂窝小区a1的基站设备可以一直使用编号为2的频谱资源发送信息。在第三组中，蜂窝小区a2的基站设备和蜂窝小区b7的基站设备对编号为3的频谱资源进行时分复用，即处于周期性“关闭”状态。如图11所示，蜂窝小区a2的基站设备和蜂窝小区b7的基站设备可以周期性使用编号为3的频谱资源发送信息并且使用的时间交错开来。如上所述，根据图11中所示的复用方式，图10中无人 机设备UAV的潜在干扰基站不会对无人机设备UAV造成下行干扰。值得注意的是，图11仅仅示出了时分复用的方式，对于其它复用方式也是类似的。
根据本公开的实施例，电子设备400还可以包括配置单元440。当生成单元410针对电子设备400也生成了资源配置信息时，生成单元410可以将针对电子设备400的资源配置信息发送到配置单元440，以使得配置单元440可以根据资源配置信息配置电子设备400用于发送信息的资源。
根据本公开的实施例，电子设备400的收发单元420还可以将生成单元410生成的所有资源配置信息发送到用户设备，以使得用户设备能够获知全部或者部分基站设备的资源配置情况，以便于信息检测和小区切换等。
图12是示出根据本公开的实施例的用于下行干扰场景的信令流程图。如图12所示，在步骤S901中，当前服务小区的基站设备获取所有基站设备用于发送信息的资源。接下来，在步骤S902中，当前服务小区的基站设备根据所有基站设备用于发送信息的资源对所有基站设备进行分组，然后针对需要资源配置的基站设备生成资源配置信息。这里假定针对除邻小区以外的其它小区的基站设备生成了资源配置信息。接下来，在步骤S903中，当前服务小区的基站设备向除邻小区以外的其它小区的基站设备发送资源配置信息。接下来，在步骤S904中，当前服务小区的基站设备向用户设备发送生成的所有资源配置信息。
由此可见，根据本公开的实施例，在下行干扰场景中，用户设备的当前服务小区的基站设备可以根据用户设备受到的干扰情况为多个基站设备生成资源配置信息，并可以向多个基站设备发送资源配置信息，以用于多个基站设备配置用于发送信息的资源。这样一来，可以避免用户设备受到下行信息的干扰。此外，这多个基站设备可以是除用户设备的当前服务小区以外的小区的基站设备，从而使得非邻小区(地理位置上相邻)的基站设备之间可以协调用于发送信息的资源，为干扰协调提供了新的思路。
<3.上行干扰场景基站侧的配置示例>
以上详细描述了根据本公开的实施例的下行干扰场景，下面将详细 描述根据本公开的实施例的上行干扰场景。
仍然以图5示出的根据本公开的实施例的电子设备400的结构的框图为例来说明上行干扰的消除。同样地，这里的电子设备400可以是无线通信系统中的基站设备，该无线通信系统可以包括多个基站设备以及多个无人机设备。电子设备400的各个单元都可以包括在处理电路中。需要说明的是，电子设备400既可以包括一个处理电路，也可以包括多个处理电路。进一步，处理电路可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是，这些功能单元可以是物理实体或逻辑实体，并且不同称谓的单元可能由同一个物理实体实现。
根据本公开的实施例，生成单元410还可以根据电子设备400受到的干扰情况生成资源配置信息。
根据本公开的实施例，收发单元420可以向除了电子设备400所在小区的邻小区以外的其它小区的基站设备发送资源配置信息，以用于其它小区的基站设备为其用户设备配置用于发送信息的资源，用户设备的当前高度高于高度阈值。
与下行干扰的场景类似，这里的用户设备可以是无人机设备，并且当用户设备的当前高度高于高度阈值时，该用户设备不能被看作是一般的UE。
如上所述，根据本公开的实施例，电子设备400可以根据其受到的干扰情况生成资源配置信息，以向除电子设备400所在小区的邻小区以外的其它小区的基站设备发送。这样一来，电子设备400可以与除电子设备400所在小区的邻小区以外的其它小区的基站设备协调用于发送信息的资源，以避免上行干扰。
根据本公开的实施例，干扰确定单元430可以确定电子设备400受到的干扰情况。具体地，干扰确定单元430可以根据与电子设备400的距离小于距离阈值的用户设备用于发送信息的资源确定电子设备400受到的干扰情况。
根据本公开的实施例，用户设备发送的信息可以包括数据信息和控制信息。控制信息还可以包括参考信号。也就是说，当电子设备400希望确定电子设备400针对数据信息受到的干扰情况时，可以根据与电子设备400的距离小于距离阈值的用户设备用于发送数据信息的资源来确定；当电子设备400希望确定电子设备400针对控制信息受到的干扰情况时，可 以根据与电子设备400的距离小于距离阈值的用户设备用于发送控制信息的资源来确定。
根据本公开的实施例，可以根据实际情况合理地设定距离阈值，以选取电子设备400可能接收到其发送的上行信息的用户设备。也就是说，根据距离阈值选取出来的用户设备是电子设备400潜在的干扰源。
根据本公开的实施例，收发单元420可以从与电子设备400的距离小于距离阈值的用户设备的当前服务小区的基站设备接收用户设备用于发送信息的资源。以图2所示的示例为例，假定UAV1的当前服务小区是蜂窝小区b7，UAV2的当前服务小区是蜂窝小区b9。根据本公开的实施例，蜂窝小区A的基站设备可以从蜂窝小区b7的基站设备接收UAV1用于发送信息的资源，并可以从蜂窝小区b9的基站设备接收UAV2用于发送信息的资源。
根据本公开的实施例，收发单元420可以通过S1接口接收与电子设备400的距离小于距离阈值的用户设备的当前服务小区的基站设备发送的用户设备用于发送信息的资源。当与电子设备400的距离小于距离阈值的用户设备的当前服务小区时电子设备400所在小区的邻小区时，收发单元420也可以通过X2接口接收用户设备用于发送信息的资源。
根据本公开的实施例，无线通信系统中的每个基站设备都可以将其服务的用户设备用于发送信息的资源发送至与该用户设备距离小于距离阈值的基站设备。这同样可以通过S1接口或X2接口来实现。
这里，用户设备可以周期性向为其提供服务的基站设备上报用户设备的位置信息，同时基站设备可以通过X2接口或S1接口获知该基站设备所在小区的邻小区的基站设备以及除该基站设备所在小区的邻小区以外的其它小区的基站设备的位置信息，从而确定与用户设备距离小于距离阈值的所有基站设备。仍然以图2所示的示例为例，假定UAV1的当前服务小区b7的基站设备确定与UAV1距离小于距离阈值的基站设备为蜂窝小区A、a1、b8和a2，则可以向这四个小区的基站设备发送UAV1用于发送信息的资源。以这种方式，蜂窝小区A的基站设备可以获取与其距离小于距离阈值的所有用户设备用于发送信息的资源。
根据本公开的实施例，当与电子设备400的距离小于距离阈值的多个用户设备用于发送信息的资源相同时，干扰确定单元430可以确定电子设备400受到干扰。这里，用于发送信息的资源可以包括用于发送信息的 频谱资源。例如，当多个用户设备用于发送信息的频谱资源相同时，干扰确定单元430可以确定电子设备400受到干扰。以图2所示的示例为例，UAV1和UAV2距离蜂窝小区A的基站设备均小于距离阈值，并且UAV1和UAV2用于发送上行信息的资源相同，从而使得蜂窝小区A的基站设备可以接收到来自UAV1和UAV2的上行信息，造成干扰。
根据本公开的实施例，当电子设备400受到干扰时，生成单元410可以针对造成干扰的多个用户设备中的部分用户设备或者全部用户设备的当前服务小区的基站设备生成资源配置信息，并且收发单元420可以向相应的基站设备发送资源配置信息，以用于相应的基站设备为其用户设备重新配置用于发送信息的资源。
根据本公开的实施例，生成单元410可以针对造成干扰的多个用户设备中的全部用户设备生成资源配置信息。这里，资源配置信息可以包括造成干扰的用户设备的标识信息等，以使得接收资源配置信息的基站设备为用户设备重新分配用于发送信息的资源，例如，为用户设备重新分配用于发送上行信息的频谱资源。在图2所示的示例中，蜂窝小区A的基站设备可以针对蜂窝小区b7的基站设备生成资源配置信息，其中包括UAV1的标识信息。当蜂窝小区b7的基站设备收到这样的资源配置信息后，得知UAV1对蜂窝小区A的基站设备造成了干扰，从而重新为UAV1分配用于发送上行信息的频谱资源。同样地，蜂窝小区A的基站设备可以针对蜂窝小区b9的基站设备生成资源配置信息，其中包括UAV2的标识信息。当蜂窝小区b9的基站设备收到这样的资源配置信息后，得知UAV2对蜂窝小区A的基站设备造成了干扰，从而重新为UAV2分配用于发送上行信息的频谱资源。
根据本公开的实施例，生成单元410可以针对造成干扰的多个用户设备中的部分用户设备生成资源配置信息。例如，造成干扰的用户设备的数目为N(其中N为大于1的整数)，那么生成单元410可以针对其中N-1个用户设备生成资源配置信息。也就是说，这多个用户设备中的一个用户设备是不需要被重新分配资源的。在图2所示的示例中，蜂窝小区A的基站设备可以针对蜂窝小区b7的基站设备生成资源配置信息，而针对蜂窝小区b9的基站设备不生成资源配置信息。可选地，蜂窝小区A的基站设备也可以针对蜂窝小区b9的基站设备生成资源配置信息，而针对蜂窝小区b7的基站设备不生成资源配置信息。这样一来，可以减少生成的资源配置信息的数目，从而减小信令开销，避免对太多的用户设备造成影 响。
如上所述，根据本公开的实施例，当距离基站设备较近的多个用户设备使用相同的资源发送上行信息时，基站设备可以接收到多个用户设备发送的上行信息，从而造成干扰。在这种情况下，电子设备400可以针对这些用户设备中的全部用户设备或部分用户设备生成资源配置信息并向相应的基站设备发送，以协调发送上行信息的资源，从而解决干扰问题。这里，造成干扰的用户设备可能来自于电子设备400所在的小区，可能来自于电子设备400所在小区的邻小区，也可能来自除电子设备400所在小区的邻小区以外的小区。因此，根据本公开的实施例，电子设备400可以向除了电子设备400所在小区的邻小区以外的其它小区的基站设备发送资源配置信息。进一步，电子设备400也可以向电子设备400所在小区的邻小区的基站设备发送资源配置信息。
根据本公开的实施例，电子设备400可以通过X2接口或者S1接口发送资源配置信息。例如，电子设备400可以通过S1接口向MME发送资源配置信息，以使得其它基站设备也可以通过S1接口从MME获取自己的资源配置信息。当然，如果接收资源配置信息的基站设备是电子设备400所在小区的邻小区的基站设备，那么电子设备400也可以通过X2接口发送资源配置信息，本公开对此不做限定。
此外，当造成干扰的用户设备来自于电子设备400所在的小区时，生成单元410还可以针对电子设备400生成资源配置信息，以用于电子设备400为其用户设备重新配置用于发送信息的资源。
图13是示出根据本公开的实施例的用于上行干扰场景的信令流程图。如图13所示，在步骤S1001中，用户设备的当前服务小区的基站设备可以获取无线通信系统中的所有基站设备的位置信息，从而确定与用户设备距离小于距离阈值的基站设备。接下来，在步骤S1002中，当前服务小区的基站设备向与用户设备距离小于距离阈值的基站设备发送用户设备用于发送信息的资源，这里假定除邻小区以外的其它小区的基站设备接收到了上述用于发送信息的资源。接下来，在步骤S1003中，除邻小区以外的其它小区的基站设备确定该基站设备是否受到了干扰，并在受到干扰时生成资源配置信息。这里假定用户设备对除邻小区以外的其它小区的基站设备造成了干扰。接下来，在步骤S1004中，向当前服务小区的基站设备发送资源配置信息。接下来，在步骤S1005中，当前服务小区的基站设备对用户设备进行资源配置，即为用户设备重新配置用于发送信息的资 源。如上所述，对除邻小区以外的其它小区的基站设备造成干扰的用户设备更换了用于发送信息的资源，从而避免了除邻小区以外的其它小区的基站设备受到的上行干扰。
由此可见，根据本公开的实施例，在上行干扰场景中，基站设备可以根据附近的用户设备用于发送信息的资源确定基站设备受到的干扰情况，并可以向为造成干扰的用户设备服务的基站设备发送资源配置信息，以用于基站设备为造成干扰的用户设备重新配置资源。这样一来，可以避免基站设备受到上行信息的干扰。此外，造成干扰的用户设备的当前服务小区可以是除受到干扰的基站设备的邻小区以外的其它小区，从而使得非邻小区的基站设备之间可以协调用于发送信息的资源，为干扰协调提供了新的思路。
