交叉引用
本发明要求在2020年08月31日提交中国专利局、申请号为202010901152.4、发明名称为“物理下行控制信道的监听方法、装置和设备”的中国专利申请的优先权，该申请的全部内容通过引用结合在本发明中。
技术领域
本申请涉及通信领域，尤其涉及一种物理下行控制信道的监听方法、装置和设备。
背景技术
在移动通信系统中，比如长期演进(Long Term Evolution，LTE)系统或新空口(New Radio，NR)系统，引入了非连续接收(Discontinuous Reception，DRX)机制，以通过配置DRX开启(on)和DRX关闭(off)时间来达到用户设备(User Equipment，UE，也可称为终端设备，用户终端，移动终端等)省电的目的。
在配置DRX时，会配置连接态下的DRX持续时间定时器(onDurationTimer)、DRX去激活定时器(drx-InactivityTimer)、DRX重复传输定时器(drx-Retransmission Timer)和长DRX周期起始偏移(longDRX-Cycle Start Offset)等参数。进一步地，在ondurationtimer运行期间，或者在DRX-inactivitytimer启动且未超时之前，UE会监听网络侧设备配置的物理下行控制信道(Physical Downlink Control Channel，PDCCH)。
因此，如何避免不必要的PDCCH盲检测，从而节省UE的功耗，成为亟待解决的技术问题。
