Description

节能指示及节能的方法及基站、设备和存储介质
本申请要求申请日为2020/2/14的中国专利申请2020100933644的优先权。本申请引用上述中国专利申请的全文。
技术领域
本发明属于通信领域，尤其涉及一种节能指示及节能的方法及基站、设备和存储介质。
背景技术
近期智能手机的兴起，手机功能越来越强大，终端的耗电直接影响用户体验，所以用户对终端节能的需求越来越强烈。
DRX(Discontinuous Reception，不连续接收)的基本机制是为处于RRC_CONNECTED态(RRC_连接态，Radio Resource Control，无线资源控制层)的UE(用户设备)配置一个DRX cycle(DRX周期)。DRX cycle由“On Duration(持续时间)”和“Opportunity for DRX(有可能进入DRX)”组成。在“On Duration”的时间内，UE监听并接收PDCCH(Physical Downlink Control Channel，物理下行控制信道)；在“Opportunity for DRX”时间内，UE不接收下行信道的数据以节省功耗。
随着5G时代的到来，人们对5G终端的省电要求越来越高，为了减少PDCCH所用功耗、提高用户的体验，现有技术针对连接态UE进行了节能信号的设置，即基站采用DCI–based(Downlink Control Information，下行控制信息)节能信号(Power saving signal,PSS)指示配置了DRX的UE是否需要在DRX on duration期间醒来监听PDCCH。
基站根据UE的业务特性能够预估UE在DRX cycle期间是否有数据到达，从而指示UE是否需要醒来，并且，基站可同时指示多个UE监听相同的DCI-based PSS。但考虑不同UE实际数据到达时间的不确定性，即使在相同组内的UE在某一DRX cycle期间都有数据调度，有时基站也不能保证在DRX on duration开始的第一个PDCCH监听时机都能调度指示要醒来的UE，如某些UE在DRX on duration期间的某时刻数据才到达，那么在DRX on duration开始的第一个PDCCH监听时机，基站是无法发送PDCCH指示调度数据的；如果缓存到下一个DRX cycle调度，数据传输时延会受到影响。
发明内容
本发明要解决的技术问题是为了克服现有技术中基站只能通过PSS指示UE在下一个DRX cycle是否要醒来监听PDCCH且监听只能从第一个PDCCH监听时机开始，由此导致对DRX cycle期间数据到达的用户，基站只能推迟到下一个DRX cycle调度该用户，从而增大用户数据调度的时延的缺陷，提供一种节能指示及节能的方法及基站、设备和存储介质。

具体实施方式
下面通过实施例的方式进一步说明本发明，但并不因此将本发明限制在所述的实施 例范围之中。
实施例1
本实施例提供一种节能指示方法，其适用于基站向用户设备进行指示，以使得用户设备达到节省功耗的目的。所述方法包括发出指示信息的步骤。其中，所述指示信息包含需要在将来第一个DRX周期醒来的至少一用户设备的对应监听信息，所述监听信息用于指示对应的用户设备在DRX on duration定时器开始后的一个指定PDCCH监听时机起监听PDCCH。
其中，一个基站对应多个用户设备，基站可根据不同用户设备的业务特性，预估每个用户设备在DRX周期期间是否有数据到达，从而确定该用户设备是否需要在将来第一个DRX周期醒来。至于上述预估的具体原理和过程可参考现有技术，在此不作具体说明。一个用户设备对应一个监听信息，所述指示信息可以同时对一个或多个用户设备进行指示，以降低信令开销。
所述指定PDCCH监听时机可以是DRX on duration定时器开始后的第一个PDCCH监听时机，也可以时DRX on duration定时器开始后的非第一个PDCCH监听时机。在DRX on duration定时器开始后的一个指定PDCCH监听时机起监听PDCCH，可理解为在DRX on duration定时器开始后，跳过(skip)指定个数的PDCCH监听时机，而从被跳过的最后一个PDCCH监听时机的后一个PDCCH监听时机开始监听PDCCH，其中，被跳过的最后一个PDCCH监听时机的后一个PDCCH监听时机即为所述指定PDCCH监听时机。例如，指示用户设备在DRX on duration定时器开始后跳过2个PDCCH监听时机，则用户设备就从第3个PDCCH监听时机开始监听。所述方法中，一个用户设备对应的监听信息具体以DRX on duration定时器开始后的哪一个PDCCH监听时机为所述指定PDCCH监听时机，可以根据所述用户设备在DRX on duration期间数据到达的时刻确定。
本实施例中，优选通过节能信号(PSS)携带所述指示信息。即在PPS中增加所述指示信息，至于PSS中原本包含的信息，如醒来指示和对于已配置载波聚合(CA，Carrier Aggregation)的用户设备的辅小区休眠指示(SCell dormancy indication)，仍可保留，本实施例对此不作修改。当然也不排除通过基站发往用户设备的其他信号携带所述指示信息的可能。
若通过所述节能信号携带所述指示信息，则每个所述用户设备对应的监听信息可以分别占用所述节能信号中的若干比特位。
优选地，对于已配置载波聚合的用户设备，其所对应的监听信息占用所述节能信号中该用户设备的辅小区休眠指示后面的若干比特位。其中，所述辅小区休眠指示后面的 若干比特位，可以是紧跟在所述辅小区休眠指示后面的若干比特位，也可以是不紧跟在所述辅小区休眠指示后面的若干比特位，即所述辅小区休眠指示与所述监听信息之间可插入其他信息，也可不插入其他信息。
本实施例中，每个所述用户设备对应的监听信息占用的所述节能信号的比特位数量可能相同或不同，所述监听信息所占用的比特位数量具体可为
Figure PCTCN2021075593-appb-000003
位，X1为所述监听信息对应的用户设备可跳过PDCCH监听时机个数的种数。
其中，所述监听信息对应的用户设备可跳过PDCCH监听时机个数是在所述用户设备进入RCC连接态后由基站给所述用户设备配置的。相应地，所述方法还包括在所述用户设备进入RRC连接态后，配置至少一种所述用户设备可跳过PDCCH监听时机个数，以及通过所配置的所述用户设备可跳过PDCCH监听时机个数的种数确定对应的X1值的步骤。
例如，一个用户设备，通过配置，可跳过PDCCH监听时机个数只为2个，则X1取1，对应的监听信息占用1bit；
另一个用户设备，通过配置，可跳过PDCCH监听时机个数为2个、4个和6个，则X1取3，对应的监听信息占用2bits。
由于一个用户设备最多配置成整个DRX on duration中每个PDCCH监听时机均可跳过，因此，X1不超过DRX on duration监听时机的总数量。例如，DRX on duration一共包含8个PDCCH监听时机长度，用户设备可跳过的PDCCH监听时机个数最多可配置8种情况，分别为1个、2个、3个、……、8个，因此X1不能超过8。
在配置所述用户设备对应的可跳过PDCCH监听时机个数时，所有可跳过的个数可看作一张列表(list)，所有可跳过的个数在列表中的位置顺序是已知的，通过指定列表中的一个位置，就可以确定对应的可跳过的个数。出于上述考虑，本实施例还将所述用户设备可跳过PDCCH监听时机个数的所配位置顺序映射为所述节能信号中对应比特位指示的码点值。
在所述指定监听时机为DRX on duration定时器开始后的非第一个PDCCH监听时机时，所述监听信息所占用的比特位设置为跳过所述指定PDCCH监听时机的前一个PDCCH监听时机时所需跳过PDCCH监听时机的个数对应的码点值。所述用户设备可通过该码点值确定对应的需跳过的PDCCH监听时机个数，从而跳过相应个数的PDCCH监听时机，从其后一个PDCCH监听时机开始监听。
在所述指定监听时机为DRX on duration定时器开始后的第一个PDCCH监听时机时，所述监听信息所占用的比特位设置为一个特定的码点值。所述特定的码点值可以为 全0或全1，或预配置的其他值。所述用户设备可通过所述特定的码点值确定需要在DRX on duration定时器开始后的第一个PDCCH监听时机起开始PDCCH监听。
下面给出所述方法的一种优化流程，具体可以包括以下步骤，如图1所示：
步骤S11：在用户设备进入RRC连接态后，给所述用户设备配置至少一种可跳过PDCCH监听时机个数；
步骤S12：通过所配置的可跳过PDCCH监听时机个数的种数确定对应的X1值；
步骤S13：根据所述用户设备在DRX on duration期间数据到达的时刻，确定所述用户设备是否需要在将来第一个DRX周期醒来以及醒来后需要跳过PDCCH监听时机的个数，其中，若要求所述用户设备从DRX on duration定时器开始后的非第一个PDCCH监听时机起开始监听，则需跳过一个以上的PDCCH监听时机，若要求所述用户设备从DRX on duration定时器开始后的第一个PDCCH监听时机，则需跳过0个PDCCH监听时机；
步骤S14：发出节能信号，所述节能信号在所述用户设备的辅小区休眠指示后面的若干比特位设置为需要跳过PDCCH监听时机的个数对应的码点值，其中，若干比特位的数量为
Figure PCTCN2021075593-appb-000004
位。
通过本实施例的方法，基站可通过所述指示信息(或包含所述指示信息的节能信号)指定不同的用户设备在DRX on duration定时器开始后从哪个PDCCH监听时机开始监听。
下面结合两个举例对携带所述指示信号后的节能信号的组成做具体说明：
例1、每个UE均只有一种可跳过PDCCH监听时机个数的配置，PSS通过
Figure PCTCN2021075593-appb-000005
指示对应的UE在DRX on duration定时器开始后是跳过所配置的PDCCH监听时机个数后开始监听，还是从第一个PDCCH监听时机开始监听：
基站配置连接态多个UE节能配置信息如下：
UE0：配置PS-RNTI(RNTI Radio Network Tempory Identity，无线网络临时标识)值，UE0信息指示在PSS DCI的起始bit位置为0，配置CA的SCell group数量为3；
UE1：配置相同的PS-RNTI值，UE1信息指示在PSS DCI的起始bit位置为6，配置CA的SCell group数量为5；
UE2：配置相同的PS-RNTI值，UE2信息指示在PSS DCI的起始bit位置为14，配置CA的SCell group数量为3；
UE3：配置相同的PS-RNTI值，UE3信息指示在PSS DCI的起始bit位置为20；
如图2所示，UE0-UE3可以看成是使用同一节能信号的一组UE，UE的业务特性相同或相近，基站配置DRX周期，slot offset(偏移时隙)等参数相同；PSS参数包括PSS  DCI的bit长度为23bits，PSS监听的搜索空间，CORESET等参数相同，UE0-UE3在每个DRX cycle开始前根据PSS参数配置指示监听PSS。
基站根据各UE的实际业务特性与DRX配置，通过节能信号PSS指示各UE一种可跳过PDCCH监听时机的数量N如下：
UE0：N＝4；
UE1：N＝2；
UE2：N＝4；
UE3：N＝6；
PSS中各UE对应的监听信息分别采用1bit指示在DRX on duration定时器开始后是跳过所配置的PDCCH监听时机个数后开始监听(对应设置该bit的码点值为1)，还是从第一个PDCCH监听时机开始监听(对应设置该bit的码点值为0)，该bit位置紧跟在SCell dormancy indication的后面。
假设当前各UE数据到达情况如下：
UE0在DRX on duration开始就有数据调度，SCell group0内激活的SCell处于非dormancy(休眠)状态，UE0需要在SCell group0内激活的SCell上监听PDCCH，接收数据调度，SCell group1和SCell group2处于dormancy状态；
UE1在DRX on duration开始没有数据调度，但在DRX on duration期间会有数据到达，基站通过PSS指示UE1的各个SCell group都处于dormancy状态；
UE2在下一个DRX周期没有数据调度，UE2不需要醒来，同时，基站通过PSS指示UE2的各个SCell group都处于dormancy状态；
UE3在DRX on duration开始就有数据调度，UE3需要醒来监听PDCCH。
则：如图3所示，基站发送的PSS DCI应为110000 10000010 000000 100，对应bit含义如下，UE0和UE3不需要跳过PDCCH监听时机，在DRX on duration开始后的第一个PDCCH监听时机起就在指示的cell上监听PDCCH，所以对应的比特位设置为0；UE2没有数据不需要醒来；UE1在DRX on duration期间才会有数据调度，UE1需要醒来，但不需要在DRX on duration开始后的第一个PDCCH监听时机起开始监听，而需要在DRX on duration开始后跳过2个PDCCH监听时机才开始监听，所以对应的比特位设置为1。UE1接收PSS后的监听状态如图4所示，图中，DRX on duration期间共6个PDCCH监听时机，其中，虚线绘制的2个监听时机为需要跳过的监听时机，实线绘制的4个监听时机为需要监听的监听时机。
例2、每个UE分别有多种可跳过PDCCH监听时机个数的配置，PSS通过Xbit指示 对应UE在DRX on duration定时器开始后是跳过所配置的某一种PDCCH监听时机个数后开始监听，还是从第一PDCCH监听时机开始监听：
基站配置连接态多个UE节能配置信息如下，与例1相同：
UE0：配置PS-RNTI值，UE0信息指示在PSS DCI的起始bit位置为0，配置CA的SCell group数量为3；
UE1：配置相同的PS-RNTI值，UE1信息指示在PSS DCI的起始bit位置为6，配置CA的SCell group数量为5；
UE2：配置相同的PS-RNTI值，UE2信息指示在PSS DCI的起始bit位置为14，配置CA的SCell group数量为3；
UE3：配置相同的PS-RNTI值，UE3信息指示在PSS DCI的起始bit位置为20；
如图5所示，UE0-UE3可以看成是使用同一节能信号的一组UE，UE的业务特性相同或相近，基站配置DRX周期，slot offset等参数相同；PSS参数包括PSS DCI的bit长度为23bits，PSS监听的搜索空间，CORESET等参数相同，UE0-UE3在每个DRX cycle开始前根据PSS参数配置指示监听PSS。
基站根据各UE的实际业务特性与DRX配置，可配置各UE PDCCH跳过PDCCH监听时机的数量如下，PSS中各UE采用X＝2bits指示在DRX on duration定时器开始后是跳过一定个数的PDCCH监听时机后开始监听，还是从第一个PDCCH监听时机开始监听，如果配置CA，则对应2bit位置紧跟在SCell dormancy indication的后面：
UE0 X1＝3：
第1种跳过PDCCH监听时机的个数N1＝2，对应2bits的码点值应为01；
第2种跳过PDCCH监听时机的个数N2＝4，对应2bits的码点值应为10；
第3种跳过PDCCH监听时机的个数N3＝6，对应2bits的码点值应为11；
UE1 X1＝3：
第1种跳过PDCCH监听时机的个数N1＝1，对应2bits的码点值应为01；
第2种跳过PDCCH监听时机的个数N2＝2，对应2bits的码点值应为10；
第3种跳过PDCCH监听时机的个数N3＝4，对应2bits的码点值应为11；
UE2 X1＝3：
第1种跳过PDCCH监听时机的个数N1＝2，对应2bits的码点值应为01；
第2种跳过PDCCH监听时机的个数N2＝3，对应2bits的码点值应为10；
第3种跳过PDCCH监听时机的个数N3＝5，对应2bits的码点值应为11；
UE3 X1＝2：
第1种跳过PDCCH监听时机的个数N1＝2，对应2bits的码点值应为01；
第2种跳过PDCCH监听时机的个数N2＝4，对应2bits的码点值应为10；
UE0-UE3，若不跳过任何个数的监听时机而从第一个PDCCH监听时机开始监听，则对应2bits的码点值设置为00。
假设当前各UE数据到达情况如下，
UE0，UE2和UE3的数据到达情况与例1相同，UE1在DRX on duration开始没有数据调度，但在DRX on duration期间会有数据到达，UE1需要跳过4个PDCCH监听时机开始监听PDCCH，基站通过PSS指示UE1的各个SCell group都处于dormancy状态。
则：如图6所示，基站发送的PSS DCI应为110000 10000011 000000 100，UE0，UE2，UE3的指示含义与例1相同。UE1对应bit含义如下，UE1在DRX on duration期间才会有数据调度，UE1需要醒来，但不需要在DRX on duration开始后的第一个PDCCH监听时机起开始监听，而需跳过PSS DCI中bit位11指示的第3种配置的跳过PDCCH监听时机，即UE1需要跳过4个PDCCH监听时机才开始监听。
UE1接收PSS后的监听状态如图7所示，图中，DRX on duration期间共6个PDCCH监听时机，其中，虚线绘制的4个监听时机为需要跳过的监听时机，实线绘制的2个监听时机为需要监听的监听时机。
实施例2
本实施例提供一种用户设备的节能方法，其适用于用户设备，以达到节省功耗的目的。所述方法包括接收指示信息的步骤。其中，所述指示信息包含需要在将来第一个DRX周期醒来的至少一用户设备的对应监听信息，所述监听信息用于指示对应的用户设备是在DRX on duration定时器开始后的一个指定PDCCH监听时机起监听PDCCH。
若所述用户设备需要在将来第一个DRX周期醒来，则按照对应的监听信息，在DRX on duration定时器开始后的所述指定PDCCH监听时机起监听PDCCH。
所述指示信息与实施例1的方法中发出的指示信息相同，关于所述指示信息的具体说明，可参考实施例1。
本实施例中，若所述指示信息携带于节能信号中，则：所述方法包括接收所述节能信号的步骤。
本实施例中，所述方法还可以包括在所述用户设备进入RRC连接态后，接收X1种跳过不同PDCCH监听时机个数的配置的步骤。
本实施例中，若所述用户设备可跳过PDCCH监听时机个数的所配位置顺序映射为所述节能信号中对应比特位指示的码点值，在所述指定监听时机为DRX on duration定时 器开始后的非第一个PDCCH监听时机时，所述监听信息所占用的比特位设置为跳过所述指定PDCCH监听时机的前一个PDCCH监听时机时所需跳过PDCCH监听时机的个数对应的码点值，则：
所述方法还包括通过所述监听信息所占用的比特位上设置的码点值，确定所述用户设备在DRX on duration定时器开始后需跳过的PDCCH监听时机个数的步骤。
本实施例中，若所述监听信息所占用的比特位设置为一个特定的码点值，则：
所述方法还包括在DRX on duration定时器开始后的第一个PDCCH监听时机起监听PDCCH的步骤。
通过本实施例的方法，用户设备可通过所述指示信息(或包含所述指示信息的节能信号)确定在DRX on duration定时器开始后从哪个PDCCH监听时机开始监听。
实施例3
本实施例提供一种基站，如图8所示，其包括：指示发出模块101。
所述指示发出模块101用于发出指示信息，所述指示信息包含需要在将来第一个DRX周期醒来的至少一用户设备的对应监听信息，所述监听信息用于指示对应的用户设备在DRX on duration定时器开始后的一个指定PDCCH监听时机起监听PDCCH。
其中，一个基站对应多个用户设备，基站可根据不同用户设备的业务特性，预估每个用户设备在DRX周期期间是否有数据到达，从而确定该用户设备是否需要在将来第一个DRX周期醒来。至于上述预估的具体原理和过程可参考现有技术，在此不作具体说明。一个用户设备对应一个监听信息，所述指示信息可以同时对一个或多个用户设备进行指示，以降低信令开销。
所述指定PDCCH监听时机可以是DRX on duration定时器开始后的第一个PDCCH监听时机，也可以时DRX on duration定时器开始后的非第一个PDCCH监听时机。在DRX on duration定时器开始后的一个指定PDCCH监听时机起监听PDCCH，可理解为在DRX on duration定时器开始后，跳过(skip)指定个数的PDCCH监听时机，而从被跳过的最后一个PDCCH监听时机的后一个PDCCH监听时机开始监听PDCCH，其中，被跳过的最后一个PDCCH监听时机的后一个PDCCH监听时机即为所述指定PDCCH监听时机。所述指示发出模块101还可以进一步用于根据所述用户设备在DRX on duration期间数据到达的时刻，确定所述用户设备对应的监听信息以DRX on duration定时器开始后的哪一个PDCCH监听时机为所述指定PDCCH监听时机。
本实施例中，优选通过节能信号(PSS)携带所述指示信息。即在PPS中增加所述指示信息，至于PSS中原本包含的信息，如醒来指示和对于已配置载波聚合(CA，Carrier  Aggregation)的用户设备的辅小区休眠指示(SCell dormancy indication)，仍可保留，本实施例对此不作修改。当然也不排除通过基站发往用户设备的其他信号携带所述指示信息的可能。
若通过所述节能信号携带所述指示信息，则每个所述用户设备对应的监听信息可以分别占用所述节能信号中的若干比特位。
优选地，对于已配置载波聚合的用户设备，其所对应的监听信息占用所述节能信号中该用户设备的辅小区休眠指示后面的若干比特位。其中，所述辅小区休眠指示后面的若干比特位，可以是紧跟在所述辅小区休眠指示后面的若干比特位，也可以是不紧跟在所述辅小区休眠指示后面的若干比特位，即所述辅小区休眠指示与所述监听信息之间可插入其他信息，也可不插入其他信息。
本实施例中，每个所述用户设备对应的监听信息占用的所述节能信号的比特位数量可能相同或不同，所述监听信息所占用的比特位数量具体可为
Figure PCTCN2021075593-appb-000006
位，X1为所述监听信息对应的用户设备可跳过PDCCH监听时机个数的种数。
所述基站还可以进一步包括：监听配置模块102。所述监听配置模块102用于在所述用户设备进入RRC连接态后，配置至少一种所述用户设备可跳过PDCCH监听时机个数，以及通过所配置的所述用户设备可跳过PDCCH监听时机个数的种数确定对应的X1值。其中，X1不超过DRX on duration监听时机的总数量。
在配置所述用户设备对应的可跳过PDCCH监听时机个数时，所有可跳过的个数可看作一张列表(list)，所有可跳过的个数在列表中的位置顺序是已知的，通过指定列表中的一个位置，就可以确定对应的可跳过的个数。出于上述考虑，本实施例还将所述用户设备可跳过PDCCH监听时机个数的所配位置顺序映射为所述节能信号中对应比特位指示的码点值。
在所述指定监听时机为DRX on duration定时器开始后的非第一个PDCCH监听时机时，所述监听信息所占用的比特位设置为跳过所述指定PDCCH监听时机的前一个PDCCH监听时机时所需跳过PDCCH监听时机的个数对应的码点值。所述用户设备可通过该码点值确定对应的需跳过的PDCCH监听时机个数，从而跳过相应个数的PDCCH监听时机，从其后一个PDCCH监听时机开始监听。
在所述指定监听时机为DRX on duration定时器开始后的第一个PDCCH监听时机时，所述监听信息所占用的比特位设置为一个特定的码点值。所述特定的码点值可以为全0或全1，或预配置的其他值。所述用户设备可通过所述特定的码点值确定需要在DRX on duration定时器开始后的第一个PDCCH监听时机起开始PDCCH监听。
本实施例的基站可通过所述指示信息(或包含所述指示信息的节能信号)指定不同的用户设备在DRX on duration定时器开始后从哪个PDCCH监听时机开始监听。
