Description

唤醒信号的发送方法及装置、寻呼解调方法及装置 技术领域
本公开涉及通信技术领域，尤其涉及一种唤醒信号的发送方法及装置、寻呼解调方法及装置、基站、用户设备和计算机可读存储介质。
背景技术
随着无线通信技术的飞速发展，出现了第五代移动通信技术(5th Generation，简称5G)。第三代合作伙伴计划(3rd Generation Partnership Project，简称3GPP)近期对5G新空口非授权频谱(New Radio Unlicensed Spectrum，简称NR-U)进行了立项研究，大部分观点认为NR-U可以支持独立组网，并且认为5G新空口(New Radio，简称NR)中的设计应该尽量被继承到NR-U中。在非授权频谱的设计上，首先需要考虑的是全球各地区有相关的法规，例如，先听后发(Listen before Talk，简称LBT)和占用信道带宽(occupied channel bandwidth，简称OCB)。LBT的含义是发射信号之前必须要先探测信道能量，如果有别的设备在这个信道上发送信号则必须按照一定的策略等待再发。
在5G NR中，需要研究非授权频谱小区独立组网的场景，对于这种新的场景，可能由于基站检测到信道被占用而错过发送同步广播块(SSB)或寻呼消息。
此外，出于对终端省电的考虑，传统的寻呼发送和接收技术带来的功耗相对较大，因此有必要引入唤醒信号。在寻呼时机(PO)之前唤醒信号通常采用序列的形式发送，有利于用户设备(UE)检测信号，从而减少功耗。同时，由于唤醒信号采用序列的形式发送，可以带来和同步信号类似的效果，有利于解决NR-U中SSB受阻的问题。
但是，如果NR-U引入唤醒信号，需要满足LBT或OCB等要求，如果单独发送唤醒信号，则会占用较多资源，尤其是在波束(Beam)较多的情况下，会占用更多的资源。
在窄带物联网(Narrow Band Internet of Things，简称NB-IoT)系统中引入唤醒信号，主要考虑它和寻呼时机之间的关系以及分组问题，不需要进行LBT。但是，对于多beam的NR-U系统，需要进行LBT，而进行LBT会引起寻呼丢失等问题。同时，也需要考虑OCB，单独发送唤醒信号，比较浪费资源。
发明内容
有鉴于此，本申请公开了一种唤醒信号的发送方法及装置、寻呼解调方法及装置、基站、用户设备和计算机可读存储介质，以解决因进行LBT引起的寻呼丢失问题，也可以减少因频繁地在PDCCH上解调寻呼消息而消耗UE的电能。

其中，由于唤醒信号的时域位置位于当前SSB的时域符号范围内，因此，唤醒信号的时域符号数小于或等于当前SSB的时域符号数。另外，可选地，有的SSB也可以不复用唤醒信 号。
在步骤S102中，向UE发送唤醒信号的时频位置。
在步骤S103中，在该时频位置发送唤醒信号。

在步骤S405中，若UE检测到唤醒信号，则在PDCCH上解调属于该UE的寻呼消息。
上述实施例，通过基站和UE之间的交互，使得基站可以在为唤醒信号配置的时频位置发送唤醒信号，增强了唤醒信号的发送效率，有效解决了因进行LBT引起的寻呼丢失问题，同时使得UE在唤醒信号的时频位置检测唤醒信号，当检测到唤醒信号时，在PDCCH上解调属于该UE的寻呼消息，从而减少因频繁地在PDCCH上解调寻呼消息而消耗的电能。
