Description

一种用于多天线系统的用户设备、基站中的方法和装置 技术领域
本申请涉及无线通信系统中的传输方法和装置，尤其涉及基站侧部署了大量天线的无线通信系统中的传输方案和装置。
背景技术
下行多天线传输中，UE(User Equipment，用户设备)通常要通过测量基站发送的下行参考信号进行下行信道估计，然后反馈CSI(Channel State Information，信道状态信息)以辅助基站执行预编码。传统的第三代合作伙伴项目(3GPP–3rd GenerationPartner Project)蜂窝网系统中，周期性(periodic)的下行参考信号被支持，包括小区公用和UE专用的下行参考信号。
下一代无线通信系统中，基站侧装备的天线数量将会大大增加，传统的周期性下行参考信号所需要的开销也将随之增加。为了降低下行参考信号的开销，3GPP R(Release，版本)13和R14中讨论了非周期性(aperiodic)的下行参考信号和使用了波束赋型的下行参考信号。
发明内容
发明人通过研究发现，非周期性的下行参考信号和周期性的下行参考信号有时会对应(部分)相同的天线端口，比如(部分)非周期性的下行参考信号和(部分)周期性的下行参考信号使用相同的波束赋型向量从相同的天线组上发送。在这种情况下，和周期性下行参考信号对应相同天线端口的非周期性下行参考信号不需要被发送，基于非周期性下行参考信号的信道估计可以联合利用(部分)周期性的下行参考信号和非周期性的参考信号来进行，从而降低非周期性的下行参考信号的开销。

在UL(Uplink，上行)中，gNB910处的功能类似于在DL中所描述的UE950处的接收功能。每一接收器918通过其相应天线920接收射频信号，把接收到的射频信号转化成基带信号，并把基带信号提供到多天线接收处理器972和接收处理器970。接收处理器970和多天线接收处理器972共同实施L1层的功能。控制器/处理器975实施L2层功能。控制器/处理器975可与存储程序代码和数据的存储器976相关联。存储器976可称为计算机可读媒体。在UL中，控制器/处理器975提供输送与逻辑信道之间的多路分用、包重组装、解密、标头解压缩、控制信号处理以恢复来自UE950的上层数据包。来自控制器/处理器975的上层数据包可被提供到核心网络。控制器/处理器975还负责使用ACK和/或NACK协议进行错误检测以支持HARQ操作。
