Description

一种被用于无线通信的用户设备、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方法和装置，尤其是涉及支持多天线的无线通信系统中的方法和装置。
背景技术
在LTE系统中，小区间切换(Handover)是基站基于UE的(User Equipment，用户设备)测量来控制的。3GPP(3rd Generation Partner Project，第三代合作伙伴项目)R(Release，版本)15中的小区间切换基本沿用了LTE中的机制。在NR(New Radio，新无线电)系统中，更多应用场景需要被支持。一些典型的应用场景，比如URLLC(Ultra-Reliable and Low Latency Communications，超高可靠性和低延迟通信)，对时延提出了很高的要求，同时也对小区间切换提出了新的挑战。
在NR系统中，大尺度(Massive)MIMO(Multiple Input Multiple Output，多输入多输出)是一个重要的技术特征。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。多天线波束赋型形成的波束一般比较窄，通信双方的波束需要对准才能进行有效的通信。
发明内容
发明人通过研究发现，基于波束的通信会给小区间切换带来负面的影响，比如额外的延时和乒乓效应。如何降低这些负面影响，并且利用波束赋型技术来进一步提高小区边界用户的性能从而满足各类应用场景的需求，是需要解决的问题。
