本申请涉及无线通信领域,尤其涉及一种功率控制方法及相关设备。
基于蜂窝网络的设备对设备(Device-to-Device,D2D)的通信。在3GPP中又称为邻近服务(Proximity Service,ProSe),是一种在***的控制下,允许终端之间通过复用小区资源直接进行通信的新型技术,该技术能够增加蜂窝通信***频谱效率,降低终端发射功率。3GPP协议中,用户设备(user equipment,UE)使用侧行链路sidelink实现邻近服务功能。
在D2D通信中,远端用户设备remote UE通过中继用户设备relay UE连接到网络中。remote UE可以是一个低能力的设备,例如可穿戴设备,其特点为体积小,电池容量小,射频能力较低。relay UE可以是一个高能力的设备,例如高能力的智能手机,其可以作为一个中继节点辅助低能力的设备连接网络,此种情况下,需要对remote UE的传输功率进行控制,以降低remote UE,同时避免对其他UE的干扰。
