Description

一种UE、基站中非周期SRS的方法和设备 技术领域
本发明涉及无线通信系统中利用非授权频谱通信的方案，特别是涉及基于LTE(Long Term Evolution，长期演进)的针对非授权频谱(Unlicensed Spectrum)的通信方法和装置。
背景技术
LTE系统中，基站能够发送DCI(Downlink Control Indicator，下行控制指示)触发A-SRS(Aperiodic Sounding Reference Signal，非周期侦听参考信号)。其中DCI格式{0，1A，2B，2C，2D，4}支持触发A-SRS。对于UE，如果接收到触发A-SRS的第一DCI，在第一DCI调度的服务小区的上行物理资源上发送SRS。
上述服务小区包括下行载波(或子帧)和上行载波(或子帧)。所述服务小区的小区索引以及所述下行载波的频带(或子帧)和所述上行载波的频带(或子帧)是由高层信令半静态配置的。
传统的第三代合作伙伴项目(3GPP–3rd Generation Partner Project)LTE系统中，数据传输只能发生在授权频谱上，然而随着业务量的急剧增大，尤其在一些城市地区，授权频谱可能难以满足业务量的需求。3GPP RAN的62次全会讨论了一个新的研究课题，即非授权频谱综合的研究(RP-132085)，主要目的是研究利用在非授权频谱上的LTE的非独立(Non-standalone)部署，所谓非独立是指在非授权频谱上的通信要和授权频谱上的服务小区相关联。一个直观的方法是尽可能重用现有系统中的载波聚合(CA-Carrier Aggregation)的概念，即部署在授权频谱上的服务小区作为主载波(PCC-Primary Component Carrier)，部署在非授权频谱上的服务小区作为辅载波(SCC-Secondary Component Carrier)。对于非授权频谱，考虑到其干扰水平的不可控制/预测，UE可能被配置更多的载波同时采用DFS(Dynamical Frequency Selection，动态频谱选择)的方式(在给定子帧)从可选的载波中选择出部分载波用于传输数据。
传统的A-SRS的触发机制在非授权频谱的通信中会遇到如下问题：
-基站无法动态触发在非调度服务小区上发送SRS(A-SRS在其调度DCI所调度的服务小区上发送)
针对上述问题，本发明公开了一种在非授权频谱上的SRS调度方法和装置。
