Description

波束恢复方法及装置 技术领域
本申请涉及通信技术领域，尤其涉及波束恢复方法及装置。
背景技术
波束(beam)是一种通信资源，不同的波束可以认为是不同的通信资源。在移动通信系统中使用波束进行信息传输，即通过在空间上朝向特定的方向发送信号，可以实现更高的天线阵列增益。发射波束可以是指信号经天线发射出去后在空间不同方向上形成的信号强度的分布，接收波束可以是指从天线上接收到的无线信号在空间不同方向上的信号强度分布。一个波束对通常包括一个发送端的发射波束和一个接收端的接收波束。当下行控制信道关联的波束的性能下降到某个门限值时，该波束失效，即无法使用该波束进行信息传输，一旦波束失效，将触发波束恢复机制。
在长期演进(Long Term Evolution，LTE)系统中，在建立无线链路过程中的初始接入、在无线链路建立失败之后的链路重建或者采用基于上行测量的定位方法以进行定位等过程中可以采用随机接入方案，具体可以为：终端设备向网络设备发送调度请求(Scheduling Request，SR)，以通知网络设备有终端设备试图接入；终端设备在预先配置的时间窗内监测控制信道，以接收网络设备下发的随机接入响应(Random Access Response，RAR)。上述随机接入方案仅针对网络设备接收到同一终端设备发送的一个SR的场景。
当下行链路(Down Link，DL)的波束对(Beam Pair Link，BPL)失效时，为了充分利用现有的资源，以及波束失效的持续时间远小于无线链路失效(Radio Link Failure，RLF)的时间窗长度，终端设备可以利用随机接入信道(Random Access Channel，RACH)资源在不同方向的多个波束上发射SR，则网络设备在时间窗内可以接收到来自同一终端设备的多个SR。而传统LTE中随机接入的处理流程仅针对网络设备收到同一终端设备发送的一个SR的场景，在网络设备收到同一终端设备发送的多个SR时如何进行随机接入处理，是目前亟需解决的问题。

本发明实施例中，终端设备在第一时间窗所包含的至少一个符号上，使用多个相同的第一波束向网络设备发送调度请求，可加大子载波间隔。
本发明实施例中，网络设备可以对终端设备配置第一时间窗。其中，第一时间窗的起 始时刻可以是配置有RACH资源的第一个符号，以图4所示的信息传输的示意图为例，配置有RACH资源的第一个符号为符号3，则终端设备可以确定第一时间窗的起始时刻为符号3。
其中，第一时间窗的长度可以是固定长度，例如7个符号，可选的，第一时间窗的长度也可以是网络设备配置的，例如3个符号或者5个符号等。
其中，网络设备可以向终端设备发送长度指示信息，以指示第一时间窗的长度。可选的，可以通过直接法指示第一时间窗的长度，例如长度指示信息为5，则终端设备可以确定第一时间窗的长度为5个符号。可选的，可以通过映射方式描述第一时间窗的长度，例如长度指示信息和第一时间窗的映射关系如表一所示：

以图4所示的信息传输的示意图为例，网络设备可以在第二时间窗所包含的符号0上，使用第一波束所属波束对所包含的另一波束向终端设备发送调度请求响应。
