Description

一种被用于无线通信的节点中的方法和装置 技术领域
本申请涉及无线通信系统中的传输方法和装置，尤其是支持蜂窝网的无线通信系统中的无线信号的传输方法和装置。
背景技术
在5G NR(New Radio，新无线)中，大规模(Massive)MIMO(Multi-Input Multi-Output)是一个重点技术。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。在5G NR中，为应对波束失败时的快速恢复，已经采纳了波束失败恢复(beam failure recovery)机制，即UE(User Equipement，用户设备)在通信过程中对服务波束进行测量，当发现服务波束质量不好时，启动波束失败恢复机制，基站继而更换服务波束。
对于多TRP(Transmission and Reception Point，发送接收点)下，基于波束的通信在发生波束失败时，如何快速恢复波束需要被进一步考虑。
发明内容
发明人通过研究发现，对于多TRP下的波束失败恢复机制是需要研究的一个关键问题。
针对上述问题，本申请公开了一种解决方案。需要说明的是，虽然上述描述采用大规模MIMO和基于波束的通信场景作为例子，本申请也适用于其他场景比如LTE多天线系统，并取得类似在大规模MIMO和基于波束的通信场景中的技术效果。此外，不同场景(包括但不限于大规模MIMO，基于波束的通信和LTE多天线系统)采用统一解决方案还有助于降低硬件复杂度和成本。在不冲突的情况下，本申请的任一节点中的实施例和实施例中的特征可以应用到其他任一节点中，反之亦然。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。
