Description

一种用于功率调整的用户设备、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支持功率调整的传输方法和装置，尤其涉及基站侧部署了大量天线的无线通信系统中的支持功率调整的传输方案和装置。
背景技术
大尺度(Massive)MIMO(Multiple Input Multiple Output，多输入多输出)成为下一代移动通信的一个研究热点。大尺度MIMO中，多个天线通过波束赋型，形成较窄的波束指向一个特定方向来提高通信质量。由于波束的宽度很窄，指向不同方向的波束经过的传输路径是不同的，这造成使用不同波束赋型向量的信号经历的长时信道衰落之间的明显差异。这种长时信道衰落之间的差异给上行功率调整带来了新的问题。
发明内容
发明人通过研究发现，在基站采用基于大尺度MIMO的多天线波束赋型的情况下，上行功率的调整和基站的接收波束赋型向量是相关的，不同的接收波束赋型向量需要对应不同的上行功率调整过程，针对某一个接收波束赋型向量的上行功率偏移量不能被基于另一个接收波束赋型向量的上行发送所使用，否则会造成基于另一个接收波束赋型向量的上行功率调整的不准确和性能损失。
