Description

通信方法、设备和存储介质 技术领域
本申请涉及通信，例如涉及一种通信方法、设备和存储介质。
背景技术
在相关技术中的蜂窝通信中，支持非连续接收(Discontinuous Reception，DRX)机制，对于无线资源控制-连接(Radio Resource Control-CONNECTED，RRC_CONNECTED)用户设备(User Equipment，UE)，如果配置了DRX机制，允许UE基于DRX配置间断性地监听物理下行控制信道(Physical Downlink Control Channel，PDCCH)，否则UE需要连续监听PDCCH。在DRX机制中，在不监听PDCCH的时间内，UE可以进入睡眠状态(sleep mode)；在需要监听PDCCH的时候，UE可以从睡眠状态中唤醒(wake up)，以使UE达到省电的目的。
在长期演进(Long Term Evolution，LTE)V2X技术中，在有Pedestrian User(P-UE)参与的边链路(SideLink)通信中(比如P2V传输)，为了节省P-UE功耗，P-UE在选择发送P2V业务的无线资源时，支持部分感知选择(Partial Sensing)的方式，对于资源选择窗[n+T1,n+T2]ms内包含的资源，在资源选择窗之前的时间范围[n+T1-1000,n+T2-100]ms内，距离n+T1时刻为P＝100ms的正整数倍的位置的资源为候选sensing资源，实际进行sensing的资源为候选sensing资源的部分或全部，具体根据高层配置参数确定。
目前，在SideLink通信中不支持DRX机制，如果在SideLink通信中引入DRX机制，可以进一步帮助P-UE节省功耗。同时，SideLink通信与蜂窝通信在资源选择、信道结构以及重传机制等方面都存在不同，即相关技术中的蜂窝通信中的DRX机制不能完全重用于SideLink通信，否则会影响SideLink通信的可靠性。

在一个边链路SideLink发送资源池中选择资源；

在一实施例中，第四激活时间可以是计数器计数对应的时间范围，从计数器开始计数到计数终止所对应的时间范围，计数单位为时间单位，比如秒或毫秒。对于SideLink通信，基于该时间范围内的有效资源上进行通信处理，比如在该时间范围内属于SideLink接收资源池的资源上进行SideLink信号和/或信道的接收处理。例如，在20ms内包含了8个属于SideLink接收资源池的slot，则UE在激活的20ms内属于SideLink接收资源池的8个slot上监听PSCCH和/或PSSCH。作为另一个实施例，还可以是基于SideLink有效slot或子帧计数所对应的时间范围，比如基于SideLink有效slot或子帧计数K次所对应的时间，比如K＝100；或者是基于SideLink资源池中的slot或子帧计数所对应的时间范围，比如，基于SideLink接收资源池中的slot或子帧计数L次所对应的时间，比如L＝32。
在一个实施例中，第四激活时间也可以是一组资源集合的方式，比如，一组可能用于SideLink传输的资源集合，或一组可能属于SideLink资源池的资源，或一组属于SideLink资源池的资源集合。例如，一组属于SideLink接收资源池的32个slot集合，这些slot在物理上可以是连续或不连续的，比如slot索引号不连续。
