Description

一种实现非连续接收的方法、终端及计算机存储介质 技术领域
本发明涉及非连续接收(Discontinuous Reception，DRX)技术，尤其涉及一种实现DRX的方法、终端及计算机存储介质。
背景技术
在长期演进(Long Term Evolution，LTE)系统中，通常采用DRX技术来实现终端的节电。这样，终端可以根据配置周期性的进行物理下行控制信道(Physical Downlink Control Channel，PDCCH)的监听。对于某些特定过程，如收到新传调度，下行重传，上行重传，非冲突随机接入下行数据等待，冲突解决，及调度请求(Scheduling Request，SR)等过程，终端需要在DRX周期外持续检测PDCCH一段时间，即终端在DRX的激活时间(active time)内都需要检测PDCCH，换句话说，上述过程都属于终端的DRX激活时间。这样，根据上述描述的几种特定过程和DRX的配置，形成了如图1所示的不规律的DRX激活时间。
随着数据业务的快速增长，授权频谱资源将不能承受如此巨大的数据量，所以LTE系统中有必要通过非授权载波来分担授权载波中的数据流量。非授权载波和授权载波可以通过载波聚合的方式使用，也可以通过双连接的方式使用。非授权载波一般作为数据传输的补充，即授权载波作为主服务小区(Primary Cell，Pcell)，非授权载波作为辅服务小区(Secondary Cell，Scell)。而且，非授权载波需要通过竞争才能使用，如果基站(包括WiFi接入点)没有竞争到资源，则不能使用非授权载波，即非授权载波的可用资源是不连续的。
因此，由于非授权载波的可用资源的不连续性，当在LTE系统中引入 非授权载波后，对于终端如何实现DRX的问题，目前尚无有效的解决方案。

应用示例一：
步骤A1：由于业务量增加，基站根据测量报告给终端增加小区3。由于小区3为非授权载波，需要通过竞争方式来获取资源使用权限，同时给终端进行了小区3的DRX配置，小区3的DRX配置可以跟小区1的一样(此时就不需要再给终端配置了)，也可以单独配置。
步骤B1：终端收到小区3的配置信息后增加小区3，开始应用小区3的DRX配置。
步骤C1：基站根据终端业务量的需求，发起小区3的资源竞争过程。

这里，若按照所述DRX重传定时器的时长需要在T4时刻结束。
步骤F2：终端根据指定的信令获知T3时刻后，小区3的资源无法被 使用，因此，在T3时刻，停止重传定时器，终端停止监测小区3的PDCCH。

步骤F3：终端根据指定的信令获知T3时刻后，小区3的资源无法被使用，因此，在T3时刻，结束上行重传过程，终端停止监测小区3的PDCCH，并通过修改当前已经发送的次数为最大重传次数-1，或者直接清除需要重传的缓冲区。
应用示例四：
步骤A4：业务量增加，基站根据测量报告给终端增加小区3。由于小区3为非授权载波，需要通过竞争方式来获取资源使用权限，同时给终端进行了小区3的DRX配置，小区3的DRX配置可以跟小区1的一样(此时就不需要再给终端配置了)，也可以单独配置。

步骤E5：终端在T2时刻收到小区3的新传调度，开始监测小区3的PDCCH，同时启动禁止DRX定时器，按照定时器的时长需要在T4时刻结束，小区3上竞争到的资源在T3时刻结束，此时禁止DRX定时器还在运 行，所以启动等待竞争资源定时器，经过设定的时间，在T3’时刻结束。
步骤F5：如图15所示的非授权载波竞争情况1中，T3’时刻结束，小区3上又重新竞争到资源，则不对禁止DRX定时器做处理，按照原来的配置到T4时间结束，即停止所述禁止DRX定时器的时间到T4。
步骤G5：如图15所示的非授权载波竞争情况2中，T3’时刻结束，小区3上未重新竞争到资源，则停止禁止DRX定时器，则禁止DRX时间到T3’。
以上实施例，小区3的资源竞争过程，可以是基站自行完成或者终端请求基站去完成，或者终端自行完成或者终端接受基站的请求去完成，不做限定。
