Description

传输发现信号的方法、 用户设备和基站 技术领域
本发明涉及通信领域, 并且更具体地, 涉及传输发现信号的方法、 用户 设备和基站。 背景技术
用户设备之间 (Device-to-Device, 筒称为 "D2D" )通信是指用户设备 之间直接进行通信。 用户设备之间的临近服务(Device to Device Proximity Service, 筒称为 "D2D ProSe" ) 已经成为第三代合作计划 (3rd Generation Partnership Project, 筒称为 "3GPP" ) 中长期演进( Long Term Evolution, 筒 称为 "LTE" )系统中的 Rd.12系统的研究课题, 并从 Rd.12系统开始支持 D2D通信。
在 D2D ProSe的研究过程中,发现信号的发送和发现信号的检测都是在 系统预留资源上周期进行,例如,用户设备 A在系统预留资源上周期发送发 现信号, 用户设备 B在系统预留资源上周期检测发现信号。 为了保证发现信 号的覆盖范围, 用户设备 A发送发现信号时一般采用最大功率发送。 为了保 证用户设备 B能够迅速的发现用户设备 A, 用户设备 A必须短周期的发送 发现信号, 例如发送发现信号的周期为 2.56秒时, 用户设备 B在最长 2.56 秒的时间内发现用户设备 A。但是用户设备 A短周期地发送发现信号,会大 大增加用户设备 A的能耗。 为了在用户设备 A向用户设备 B发送发现信号 的同时降低用户设备 A的能耗, 用户设备 A可以长周期地发送发现信号, 例如发送发现信号的周期是 600秒,但是会导致用户设备 B可能需要很长时 间才能发现用户设备 A。
