Description

一种用于随机接入的用户设备、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RA(Random Access，随机接入)方案，特别是涉及采用了MIMO(Multiple Input Multiple Output，多输入输出)技术的无线通信系统中的RA方案。
背景技术
大尺度(Massive)MIMO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。多天线波束赋型形成的波束一般比较窄，通信双方需要获得对方的部分信道信息才能使形成的波束指向正确的方向。在UE(User Equipment，用户设备)进行RA之前，基站无法获得UE的信道信息，因此如何使RA过程受益于大尺度MIMO是一个需要研究的问题。
传统的3GPP(3rd GenerationPartner Project，第三代合作伙伴项目)LTE(Long Term Evolution，长期演进)系统中基于竞争的RA过程(Contention Based RA Procedure)包括四个步骤：UE向基站发送随机前导序列(preamble)；基站向UE发送RAR(Random Access Response，随机接入答复)；UE向基站发送层2/层3(Layer2/Layer3)信息；基站向UE发送竞争解决(contention resolution)信息。
发明内容
发明人通过研究发现，在进行RA过程之前，UE可以利用一些下行公共信号(例如同步信号，广播信号，参考信号等)获得部分信道信息，在RA的第一步中，通过发送随机前导序列将信道信息通知基站，因此在RA的第二步和第四步中，基站就能够基于UE的信道信息利用多天线波束赋型向UE发送RAR和竞争解决信息，提高RA的效率和质量。
由于不同的UE很可能需要不同的波束赋型向量，但现有系统中RAR对应的DCI(Downlink Control Information)信令的信令标识不能反应其所使用的波束赋型向量，因此UE可能需要接收多个波束赋型向量 对应的RAR，尽管实际上UE只需要接收和自己相关的波束赋型向量对应的RAR。这导致了UE处理复杂度的提高。
本申请针对上述问题公开了一种方案。需要说明的是，在不冲突的情况下，本申请的UE中的实施例和实施例中的特征可以应用到基站中，反之亦然。进一步的，在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。
