需要说明的是，在本说明书中，用“和”、“或”、“和/或”连接的两者可能表示在不同应用场景下对同一意旨的不同表述方法，二者之间可能存在包含与被包含的关系，未必是指完全不同的内容。
以下，对本发明的相关技术给出说明。
UAV的移动
UAV UE的移动可以是多种多样的：可以是在垂直方向上固定在某个高度，在水平方向上移动；也可能是在水平方向上固定在某个地点，在垂直方向上移动；还可能是在垂直方向和水平方向上同时移动。在移动的过程中，UAV UE还可能朝向相同或者不同的角度。
UAV标识广播
UAV标识可以是UAV远端标识Remote ID(标识：identification或者identifier等)，该标识可以用来标识UAV设备。Remote ID可以通过广播等方式被其他UAV UE、控制端(设备或者人员)、以及第三方设备等获知，从而实现跟踪UAV UE，控制UAV UE，以及对UAV UE的飞行轨迹、飞行安全、飞行的法律法规约束等进行控制。UAV Remote ID可能包含UAV UE的会话标识，序列号，地面基站的位置信息，紧急状态指示，合规信息等 多种信息。
UAV Remote ID的广播方式可以包含通过PC5接口广播和MBS方式广播。
PC5接口是UE和UE之间进行控制面和用户面侧行通信的接口。当UAV Remote ID通过PC5接口广播，一般是由UAV UE通过PC5接口的广播方式将UAV Remote ID进行发送。
当UAV Remote ID通过MBS方式广播，一种可能的实现方式是UAV UE在注册过程中将自己的UAV Remote ID发送给网络，网络通过MBS广播服务(例如建立MBS会话)广播UAV Remote ID。需要获取UAV Remote ID的UAV UE或者其他设备通过接收MBS广播服务来获取UAV Remote ID。MBS广播服务需要基站通过空口进行MBS广播，因此只有UE处于基站的覆盖范围内才能接收到MBS广播。
当UAV UE处在网络覆盖范围内，可以通过MBS方式广播UAV Remote ID。当UAV UE处在网络覆盖范围外，可以通过PC5接口方式广播UAV Remote ID。
PC5接口传输
PC5接口的传输方式分为单播、组播和广播。PC5接口的传输一般为侧行通信(sidelink)传输。
单播方式，指两个UE之间进行通信传输。对于单播方式，上层Upper layer(s)为单播通信建立PC5单播链路(unicast link)，一个PC5单播链路建立就会对应有一个PC5-RRC连接建立。PC5-RRC连接是一对源层二ID和目标层二ID之间的AS层逻辑连接。不同的UE可能对应不同的源层二ID和目标层二ID。
组播方式，指在一组UE之间进行通信传输。组播方式可以对于一组UE采用一个目标层二ID，属于这一组的UE都可以通过该目标层二ID来接收该服务的组播信息。
广播方式，指在多个UE之间进行通信传输。广播方式可以对于一种服务采用一个目标层二ID，多个UE都可以通过该目标层二ID来接收该种服务的广播信息。
UE基于PC5接口传输可能处于如下三种场景中的一种：
1)覆盖范围内：UE处于覆盖范围内；
2)覆盖范围外：UE处于覆盖范围外；
3)部分覆盖：UE和与之通信的另一个或者另一些UE，至少有一个UE在覆盖范围内，并且至少有一个UE在覆盖范围外。
这里所述的覆盖范围指的是UE是否处在基站的覆盖范围内还是覆盖范围外。
UE通过PC5接口进行通信传输需要使用PC5接口的无线资源。一般存在两种资源分配模式，一种模式为网络提供资源分配，另一种模式为UE在资源池中选择资源。UE可以通过网络发送的系统消息或者RRC专有信令获取资源池的配置，也可以通过预配置获取资源池的配置。在NR中，sidelink资源分配模式1对应网络提供资源分配，sidelink资源分配模式2对应UE在资源池中选择资源。
Sidelink通信发送
在NR中，如果用于sidelink通信的频率包含在RRC专有信令(例如RRCReconfiguration消息)中(或如果UE处于RRC连接态)，配置底层执行资源分配模式1，即，使用RRC专有信令中配置的发送资源；如果用于sidelink通信的频率在系统消息(例如SIB12消息)中(或如果UE处于RRC空闲态或者RRC非激活态)，配置底层执行sidelink资源分配模式2，使用系统消息中配置的发送资源池，即在系统消息中配置的发送资源池中选择发送资源；如果用于sidelink通信的频率既没有包含在RRC专有信令中也没有包含在系统消息中(即UE处于覆盖范围外)，UE配置底层执行sidelink资源分配模式2，使用预配置中配置的发送资源池，即在预配置所配置的发送资源池中选择发送资源。
在LTE中，如果UE在覆盖范围内，若UE处于RRC连接态，配置底层使用RRC专有信令中配置的发送资源，若UE处于RRC空闲态或者RRC非激活态，配置底层使用系统消息中配置的发送资源池，即在系统消息配置的发送资源池中选择发送资源；如果UE在覆盖范围外，配置底层使用预配置中配置的发送资源池，即在预配置所配置的发送资源池中选择发送资源。
在发送资源池配置中(资源池配置可以包括多种物理资源的发送配置，例如PSSCH的发送配置)可以包含水平速度门限值，以及高于该水平速度门限的参数配置，和/或低于该水平速度门限的参数配置。当UE的绝对水 平速度低于水平速度门限值，则UE采用低于该水平速度门限的参数配置。当UE的绝对水平速度等于或者高于水平速度门限值，则UE采用高于该水平速度门限的参数配置。
Sidelink通信接收
在NR中，如果用于sidelink通信的频率包含在RRC专有信令(例如带有同步重配的RRCReconfiguration消息)中(或如果UE处于RRC连接态)，配置底层使用RRC专有信令中所配置的接收资源池监听sidelink控制信息和对应的数据，即在RRC专有信令配置的接收资源池中选择接收资源；如果用于sidelink通信的频率在系统消息(例如SIB12消息)中(或如果UE处于RRC空闲态或者RRC非激活态)，配置底层使用系统消息中所配置的接收资源池监听sidelink控制信息和对应的数据，即在系统消息配置的接收资源池中选择接收资源；如果用于sidelink通信的频率既没有包含在RRC专有信令中也没有包含在系统消息中(即UE处于覆盖范围外)，配置底层使用预配置中所配置的接收资源池监听sidelink控制信息和对应的数据，即在预配置所配置的接收资源池中选择接收资源。
在LTE中，如果UE在覆盖范围内，配置底层使用系统消息中所配置的接收资源池监听sidelink控制信息和对应的数据，即在系统消息配置的接收资源池中选择接收资源；如果UE在覆盖范围外，配置底层使用预配置中所配置的接收资源池监听sidelink控制信息和对应的数据，即在预配置所配置的接收资源池中选择接收资源。
对于UAV Remote ID广播，在部分覆盖的场景下，处于覆盖范围内的UAV UE(s)如果只能通过MBS方式广播UAV Remote ID，则处于覆盖范围外的邻近的UE(s)是无法接收到UAV Remote ID。同样的，处于覆盖范围外的UAV UE(s)通过PC5接口广播UAV Remote ID，如果处于覆盖范围内的邻近的UE(s)只能接收MBS广播则无法接收到UAV Remote ID。特别是在基站(小区)覆盖边缘时，上述场景变得更为普遍。
为了解决上述问题，本发明讨论UAV UE在何种条件下采用PC5接口广播UAV Remote ID。同时，考虑到UAV UE的移动特点，本发明还讨论通过PC5接口广播UAV Remote ID时如何选择无线资源。通过本发明，可以使UAV UE在合适的条件下通过PC5接口广播UAV Remote ID，使其他 UE能够获取到所述UAV UE的UAV Remote ID，以便及时正确地控制所述UAV UE和所述其他UE通信，从而更好地保障服务。同时，通过本发明，还可以使UAV UE在通过PC5接口广播UAV Remote ID时，能够选择到更合适的无线资源来保证业务质量。
