本公开实施例涉及通信领域，尤其涉及一种侧链路中继处理的方法和用户设备。
背景技术
长期演进(Long Term Evolution，LTE)系统支持副链路(sidelink，或译为侧链路，边链路等)，用于终端用户设备(User Equipment，UE)之间不通过网络设备进行直接数据传输。5G NR系统可用于LTE所不支持的6GHz以上工作频段，支持更大的工作带宽，NR系统也支持终端之间直接通信的Sidelink接口通信。
已有的sidelink中继(relay)分为两种情况，一种是远程用户设备(Remote UE)和中继用户设备(relay UE)都在基站覆盖内；另一种是Remote UE在基站覆盖外，relay UE在基站覆盖内。
Remote UE和relay UE通过发现程序(discovery procedure)相互发现，之后进行sidelink的通信，在此过程中，relay UE仅对外宣称是否支持中继功能，Remote UE仅能够获知其是否提供中继功能而无法获知其具体的中继能力。

中继用户设备通过单播、组播或广播向远程用户设备发送中继用户设备的中继能力参数。
在一种可能的实现方式中，可以通过传输信号的资源，标识所述中继用户设备的中继能力参数。具体地，relay UE可以通过在不同的资源上发送discovery来标识relay UE的中继能力参数，从而区分不同中继用户设备的不同中继能力。
例如，可以根据不同的时频资源来区分不同的UE能力，具体地，基站处理中继能力参数为100M速率的UE在F1上发送发现信号，中继能力参数为200M速率的UE在F2上发送发现信号。由此，通过传输信号的资源就能够识别中继用户设备的中继能力参数。除了时频视频资源还可以通过不同的发现信号来实现区分不同的中继能力参数。
S324：远程用户设备接收所述中继用户设备的中继能力参数。
S326：远程用户设备在接收所述中继用户设备的中继能力参数之后，发送第一连接请求，从而建立中继连接。

在远程用户设备决定建立中继连接的情况下，向中继用户设备发送第一连接请求。
S316：中继用户设备接收第一连接请求从而建立中继连接。
本公开实施例在此示出了前述步骤S312的一种具体实现方式。当然，应理解，步骤S312也可以采用其它的方式实现，本公开实施例对此不作限制。
在一种可能的实现方式中，步骤S312可以包括：根据所述中继用户设备测量的通用地面无线接入网UTRAN和所述中继用户设备之间的无线接口Uu口的信号条件，确定所述中继用户设备的中继能力参数。
例如，基站处理relay UE针对驻留的小区的下行参考信号接收功率(RSRP)为20dbm时，relay UE可以确定自己的中继能力参数包括支持的最大速率为10M速率。在relay UE针对驻留的小区的下行RSRP为40dbm时，relay UE可以确定自己的中继能力参数包括支持的最大速率为20M速率。
在一种可能的实现方式中，步骤S312可以包括：根据中继用户设备 连接的服务小区的特性，确定所述中继用户设备的中继能力参数。

在一种可能的实现方式中，步骤S312可以包括：根据所述中继用户设备为当前远程用户设备提供服务后的剩余资源，确定所述中继用户设备的中继能力参数。
具体来讲，可以relay UE可以确定总中继能力参数，从总中继能力参数中减去为当前远程用户设备提供服务的资源，得到为当前远程用户设备提供服务后的剩余资源，从而确定所述中继用户设备的中继能力参数。
例如，relay UE共可以提供100M relay能力，目前服务两个remote UE，为一个UE提供50M速率，为另一个remote UE提供30M速率，因此该relay UE可以确定自己的中继能力参数为20M速率。

反之，在步骤S412中确定的中继能力参数不满足远程用户设备的目标中继能力参数的情况下，中继用户设备可以不响应第二连接请求，不建立与该远程用户设备间的中继连接，同时也可以向该远程用户设备发出表示无法建立中继连接的通知。
S426：远程用户设备接收所述中继用户设备发送的连接通知，从而建立中继连接。
在一种可能的实现方式中，步骤S412可以包括：根据所述中继用户设备测量的通用地面无线接入网UTRAN和所述中继用户设备之间的无线接口Uu口的信号条件，确定所述中继用户设备的中继能力参数。
在一种可能的实现方式中，步骤S412可以包括：根据所述中继用户设备连接的服务小区的特性，确定所述中继用户设备的中继能力参数。
