Description

一种用户设备、基站中的随机接入的方法和装置 技术领域
本申请涉及无线通信系统中的传输方案，特别是涉及随机接入的方法和装置。
背景技术
未来无线通信系统的应用场景越来越多元化，不同的应用场景对系统提出了不同的性能要求。为了满足多种应用场景的不同的性能需求，在3GPP(3rd Generation Partner Project，第三代合作伙伴项目)RAN(Radio Access Network，无线接入网)#72次全会上决定对新空口技术(NR，New Radio)进行研究。
大规模(Massive)MIMO成为下一代移动通信系统NR的一个研究热点。大规模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。在通信双方获得对方的部分信道信息之前，或者之前获得的部分信道信息已经失效的情况下，发送端和接收端需要使用更大的冗余度来确保发送信号的正确接收，比如波束扫荡(Beam Sweeping)方案，即发送端通过TDM(Timing Division Multiplexing，时分复用)的方式多次发送同样的信号，每次发送针对不同方向的波束，同时接收端使用不用的接收波束在重复的信号中选择合适的信号。在用户设备发起初始随机接入的过程中(比如基于碰撞的随机接入)，当上下行的波束间不具有互益性(Reciprocity)，即无法通过接收波束来判断发送波束，或者通过发送波束来判断接收波束时，用户设备和基站设备都需要采用波束扫荡保证随机接入信道的正确接收。
发明内容
在初始随机接入的过程中，两个(或多个)不同的用户设备(UE)采用竞争的方式向基站发起随机接入请求，如果存在至少两个用户设备选择了相同的前导序列(Preamble)并且在对Preamble的发送采用波 束扫荡的过程中，基站有可能接收到来自两个或多个不同时刻的相同的Preamble，这就会造成基站无法判断这些相同的Preamble是来自同一个用户设备还是不同的用户设备，从而造成在随机接入的后续步骤中包括随机接入响应(Msg2)，Msg3和冲突解决(Msg4)携带的信息出现偏差或者模糊。尤其当基站是在不同的Beam上收到的多个相同的Preamble时，发送这些Preamble的用户设备由于空间复用不会发生碰撞，从而都可以成功接入，但是基于现有的随机接入方式，比如LTE(Long Term Evolution，产期演进)中的随机接入方式，在相同的时频资源中发送相同的Preamble的用户设备中只有一个可以最终成功接入。如果沿用现有(比如LTE)的随机接入方式，由于上述的模糊导致基站做出错误的碰撞解决决定，或者导致资源的浪费和随机接入延时的增大。
针对由于随机接入过程采用波束扫荡造成的碰撞模糊与资源浪费的问题，本申请提供了解决方案。采用本申请的解决方案，通过支持随机接入过程中的Msg2，Msg3或者Msg4的多波束发送，同时将各个步骤的波束信息相关联解决了由于波束扫荡造成的模糊，并且支持空间的随机接入复用，提高随机接入的性能。需要说明的是，在不冲突的情况下，本申请的UE(User Equipment，用户设备)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。
