相关申请的交叉引用
本申请要求享有于2019年04月02日提交的名称为“无线链路监控方法、终端、基站和存储介质”的中国专利申请201910263195.1的优先权，该申请的全部内容通过引用并入本文中。
技术领域
本申请涉及通信领域，尤其涉及无线链路监控方法、终端、基站和存储介质。
背景技术
长期演进(Long Term Evolution，LTE)系统支持旁链路(sidelink，也称副链路、侧链路或边链路)传输，即不同终端(User Equipment，UE)之间不通过网络设备进行数据传输，而是直接在物理层上进行数据传输。LTE sidelink基于广播进行通信，其设计适用于特定公共安全事务(如火灾、地震等灾难场所)中的紧急通讯，以及车联网(vehicle to everything，V2X)通信等。V2X通信包括多种业务，例如基本安全类通信、高级(自动)驾驶通信、编队通信、传感器扩展通信，等等。
在LTE sidelink中，UE通过物理旁链路控制信道(Physical Sidelink Control Channel,PSCCH)发送旁链路控制信息(Sidelink Control Information，SCI)，调度物理旁链路共享信道(Physical Sidelink Shared Channel,PSSCH)的传输以发送数据，其中该传输以广播形式进行，接收端不向发送端应答数据接收是否成功。
由于LTE sidelink通信中接收端并不向发送端应答数据接收是否成功，因此，虽然其可用于V2X的基本安全类通信，但并不适用于其他更高级的V2X业务。可见，当前LTE sidelink技术已不能满足日益增长的实际应用需求。
