下行通道监听方法、终端、基站及存储介质 技术领域
本公开是关于通信技术领域，具体来说是关于一种下行通道监听方法、终端、基站及存储介质。
背景技术
通信系统中，基站通常通过下行通道向终端发送指令，由终端对下行通道进行监听，以接收下行通道传输的指令。考虑到持续监听下行通道会消耗过多的电量，目前提出了一种监听方法，能够根据控制信号对下行通道进行监听。
终端配置有监控时间段和非监控时间段，在监控时间段监听下行通道，在非监控时间段进入休眠状态，停止监听下行通道。并且，基站可以通过下行通道向终端发送控制信号，包括唤醒信号或者休眠信号，通过控制信号来控制终端对下行通道的监听。当终端监听到唤醒信号时，确定会在下一个监控时间段监听下行通道，而当终端未监听到唤醒信号，则在下一个监控时间段不再监听下行通道。而当终端监听到休眠信号时进入休眠状态，停止监听下行通道，当休眠状态的持续时长达到预设时长时，停止休眠。
在载波聚合场景下，终端配置有多个下行通道，通过每个下行通道接收控制信号，根据接收到的控制信号对相应的下行通道进行监听，这会消耗过多的通信资源和过多的电量。

具体实施方式
为使本公开的目的、技术方案和优点更加清楚明白，下面结合实施方式和附图，对本公开做进一步详细说明。在此，本公开的示意性实施方式及其说明 用于解释本公开，但并不作为对本公开的限定。
本公开实施例提供一种下行通道监听方法、终端、基站及存储介质，以下结合附图对本公开进行详细说明。
图1是根据一示例性实施例示出的一种通信系统的结构示意图，如图1所示，该通信系统包括基站101和终端102，基站101与终端102之间通过通信网络连接。
在通信过程中，基站101与终端102之间配置有下行通道和上行通道，基站101可以通过下行通道向终端102发送信号或指令，终端102可以通过上行通道向基站101发送信号或指令，从而实现基站101和终端102的交互。
为了满足单用户峰值速率和系统容量提升的要求，目前提出了载波聚合场景。载波聚合场景下，基站101配置有多个小区，包括Pcell(Primary Cell，主小区)和Scell(Secondary Cell，辅小区)，每个小区包括至少一个上行通道和至少一个下行通道，则基站101可以通过多个下行通道向终端102发送信号或指令，终端102可以通过多个上行通道向基站101发送信号或指令，从而实现基站101和终端102的交互。
为了及时监听到基站101发送的指令，终端102可以监听一个或多个下行通道，从而监听通过下行通道发送的指令。其中，该下行通道可以为小区的PDCCH(Physical Downlink Control Channel，物理下行控制信道)信道或者其他类型的信道。该指令可以为PDCCH授权指令、调度指令或者控制指令，或者也可以为其他指令。且，为了节省电量，终端102不实时监听下行通道，而是根据基站101发送的控制信号对下行通道进行监听，减少功率消耗，相比于频繁监听，该方式更加省电。

图4是根据一示例性实施例示出的一种下行通道监听方法的流程图，本实施例的交互主体为基站和终端，对根据目标小区范围确定控制信号生效的目标小区的方式进行说明，如图4所示，包括以下步骤：
在步骤401中，基站向终端发送控制信号，控制信号中携带目标小区范围。
本公开实施例中，基站设置有多个小区，每个小区包括至少一个下行通道，从而使基站与终端之间可以通过多个下行通道进行通信。
对于每个下行通道，基站通过该下行通道向终端发送指令，而终端监听该下行通道，检测基站通过下行通道发送的指令。并且，基站可以向终端发送控制信号，终端接收该控制信号，根据该控制信号，对该下行通道进行监听。
在一种可能实现方式中，该控制信号为唤醒信号，终端配置有监听唤醒信号的监听规则，该监听规则包括监听周期、监控时间段在监听周期内的起始时间点和持续时长，以及非监控时间段在监听周期内的起始时间点和持续时长。
其中，监控时间段在监听周期内的起始时间点可以采用该起始时间点相对于监控时间点的起始时间点的偏移量表示。
则基站向终端发送唤醒信号，终端仅在监听到唤醒信号的情况下，才会在下一个监控时间段监听下行通道，而在未监听到唤醒信号的情况下，将不会在下一个监控时间段监听下行通道。另外，在非监控时间段，终端会进入休眠状态，不再监听下行通道。
在另一种可能实现方式中，该控制信号为休眠信号，终端配置有监听休眠信号的监听规则，该监听规则包括进入休眠状态的起始时间点及休眠状态的持续时长。其中，进入休眠状态的起始时间点可以为终端监听到休眠信号的时刻，也可以为在监听到休眠信号后发生某种预设事件的时刻，或者，也可以为其他时刻。
则基站向终端发送休眠信号，终端监听到休眠信号时，按照进入休眠状态的起始时间点及休眠状态的的持续时长进行休眠。
需要说明的是，基站和终端可以协商确定上述两种监听规则，如基站可以通过高层信令、MAC CE(Media Access Control Control Element，媒体访问控制控制元素)信令、物理层信令或者其他信令，将上述两种监听规则发送给终端，或，基站可以不通过信令发送给终端，而是在传输协议中设置上述两种监听规则。
本公开实施例中，考虑到若分别发送针对每个下行通道的控制信号，会消耗终端过多的通信资源和电量，因此，通过设置目标小区范围，确定控制信号生效的目标小区，从而确定控制信号生效的下行通道和无效的下行通道。
首先，基站通过下行通道向终端发送控制信号，由终端通过该下行通道接收该控制信号。
在一种可能实现方式中，基站为终端配置有一个主下行通道和至少一个辅下行通道，则基站可以通过主下行通道发送控制信号，由终端接收通过主下行通道发送的控制信号。或者，基站可以通过辅下行通道发送控制信号，由终端接收通过辅下行通道发送的控制信号。
在步骤402中，终端接收控制信号，获取控制信号携带的目标小区范围，确定目标小区的目标下行通道。
基站向终端发送控制信号时，在控制信号中添加目标小区范围，目标小区范围用于确定控制信号生效的至少一个目标小区，则终端接收控制信号，即可从控制信号中获取控制信号的目标小区范围，确定控制信号生效的至少一个目标小区，将控制信号生效的目标小区与其他小区加以区分，进而将目标小区的下行通道确定为控制信号生效的目标下行通道，而将其他小区的下行通道确定为控制信号无效的下行通道。
终端获取控制信号携带的目标小区范围的方式包括但不限于以下两种：
第一种，基站在控制信号中添加目标小区范围，则发送的控制信号中携带目标小区范围，终端即可从控制信号中直接获取控制信号的目标小区范围。
在一种可能实现方式中，目标小区范围采用目标小区字段的形式表示，基站在控制信号中添加目标小区字段，目标小区字段包括每个小区的指示标识，指示标识用于指示控制信号是否生效。终端接收到控制信号时，获取控制信号的目标小区字段，根据目标小区字段中每个小区的指示标识确定控制信号生效的目标小区。
目标小区字段中可以包括多个比特位，分别表示多个小区的指示标识，指 示标识为第一标识时，表示对应的小区为控制信号生效的目标小区，而指示标识为第二标识时，表示对应的小区为控制信号无效的小区。
例如，目标小区字段中第一个比特位为Pcell的指示标识，第二个比特位为Scell 1的指示标识，第三个比特位为Scell 2的指示标识。指示标识为1，表示对应的小区为控制信号生效的目标小区，指示标识为0，表示对应的小区为控制信号无效的小区。
第二种，基站在控制信号中添加第一索引标识，终端接收到控制信号时，获取控制信号携带的第一索引标识，根据第一索引标识查询第一索引表，获取与第一索引标识对应的目标小区范围。
基站可以根据一个或多个可能的目标小区范围创建第一索引表，发送给终端，由终端存储该第一索引表。或者终端可以根据与基站之间的协议确定第一索引表。其中，第一索引表中包括每个第一索引标识对应的目标小区范围，不同的第一索引标识对应不同的目标小区范围，每个目标小区范围内可以包括至少一个目标小区。则基站只需向终端发送第一索引标识即可确定对应的目标小区范围，从而根据目标小区范围确定控制信号生效的目标小区。此种方式中，无需基站向终端发送目标小区范围本身，节省了通信资源，加快了通信速度。
其中，目标小区范围包括控制信号生效的目标小区的小区标识，小区标识用于确定唯一的小区，可以为小区序号、小区名称等。目标小区范围可以包括终端所属的所有小区的小区标识，或者部分小区的小区标识。且，目标小区范围内可以包括Pcell和至少一个Scell的小区标识，表示控制信号适用于包含Pcell在内的多个目标小区。或者，目标小区范围内还可以不包括Pcell的小区标识，表示控制信号适用于全部或部分的Scell，而不适用于Pcell。
例如，该第一索引表可以如下表1所示，如果第一索引标识为1，则对应的目标小区范围包括Pcell。
表1
第一索引标识 目标小区范围
1 Pcell
2 Pcell，Scell 1
3 Pcell，Scell 1，Scell 2
在一种可能实现方式中，基站可以通过高层信令或者物理层信令等多种方式，向终端发送该第一索引表。
并且，基站可以为所有的终端创建第一索引表，发送给每个终端，后续每个终端可以根据存储的第一索引表进行监听。或者，基站也可以根据每个终端所属的小区，单独为每个终端创建第一索引表，将每个终端的第一索引表分别发送给相应的终端，后续每个终端可以根据各自存储的第一索引表进行监听。且不同终端的第一索引表中，目标小区范围可以相同或者不同。
需要说明的是，本公开实施例仅是以控制信号携带目标小区范围为例进行说明，而在另一实施例中，基站为终端配置目标小区范围时，也可以采用其他方式进行配置。
如基站获取控制信号的目标小区范围，向终端发送目标小区范围，终端存储该目标小区范围。其中基站发送目标小区范围时，可以通过广播消息或者专用信令进行发送。或者，终端根据与基站之间的协议确定目标小区范围，无需基站发送。
或者，基站可以在为终端创建新的下行通道时，向终端发送更新的目标小区范围，创建不同下行通道时基站发送的目标小区范围可以相同，也可以不同。
或者，基站为终端配置多种类型的控制信号，不同类型的控制信号可以包括不同的类型标识，或者采用的加扰方式不同。每次基站在为终端创建新的下行通道时，通过该下行通道发送控制信号的类型，指示终端根据相应类型的控制信号对该下行通道进行监听。则终端将该下行通道的小区标识添加至与该控制信号的类型对应的目标小区范围内，接收到控制信号时，确定控制信号的类型对应的目标小区范围，从而确定控制信号生效的目标小区。
在步骤403中，终端根据控制信号，对目标下行通道进行监听。
在一种可能实现方式中，该控制信号为唤醒信号，终端监听任一个或多个下行通道的唤醒信号，当监听到唤醒信号时，对于目标下行通道，该唤醒信号生效，则在下一个监控时间段监听目标下行通道。而对于除目标下行通道以外的其他下行通道，唤醒信号无效，则终端在下一个监控时间段不会监听该其他下行通道。
另外，当终端未监听到唤醒信号时，在下一个监控时间段不会监听下行通道。在非监控时间段，终端会进入休眠状态，不再监听下行通道。
本公开实施例通过设置目标小区范围的方式，采用一个唤醒信号即可控制终端在下一个监控时间段对全部小区或者部分小区进行监听，操作简便，简化了基站与终端之间的交互，节省了通信资源。
在另一种可能实现方式中，该控制信号为休眠信号，终端监听任一个或多个下行通道的休眠信号，当监听到休眠信号时，对于目标下行通道，该休眠信号生效，则按照进入休眠状态的起始时间点及休眠状态的的持续时长进行休眠。而对于除目标下行通道以外的其他下行通道，休眠信号无效，则终端不会按照进入休眠状态的起始时间点及休眠状态的的持续时长进行休眠。另外，在非监控时间段，终端会进入休眠状态，不再监听下行通道。
本公开实施例通过设置目标小区范围的方式，采用一个休眠信号即可控制全部小区或者部分小区进行休眠，操作简便，简化了基站与终端之间的交互，节省了通信资源。
需要说明的是，不同的下行通道可以设置相同的监听规则，则监听周期、监控时间段在监听周期内的起始时间点和持续时长，以及非监控时间段在监听周期内的起始时间点和持续时长均相同。终端可以按照设置的监听规则进行监听。或者，不同的下行通道可以设置不同的监听规则，则终端可以按照目标下行通道的监听规则，对目标下行通道进行监听。或者，当终端通过某一下行通道发送控制信号时，终端可以按照发送控制信号的下行通道的监听规则，对目标下行通道进行监听。或者，终端还可以按照主下行通道的监听规则，对目标下行通道进行监听，或者还可以采用其他方式确定监听目标下行通道时的监听规则。
本公开实施例提供的方法，通过接收控制信号，获取控制信号的目标小区范围，根据目标小区范围确定控制信号生效的目标小区的目标下行通道，根据控制信号，对目标下行通道进行监听。本公开实施例提供了对控制信号生效的目标下行通道进行监听的方式，无需针对每个目标下行通道单独向终端发送控制信号，即可确定控制信号生效的目标下行通道，节省了通信资源和电量。
并且，终端先获取第一索引表，每次基站发送控制信号时，在控制信号中携带第一索引标识，而无需携带目标小区范围本身，终端根据第一索引标识查询第一索引表确定对应的目标小区范围即可，由于第一索引标识的数据量小于目标小区范围的数据量，因此携带第一索引标识的方式减小了数据量，节省通信资源，加快了通信速度。
本公开实施例还可以应用于双连接的场景下，控制信号可以适用于双连接场景的每个小区组，此时的Pcell可以为主小区组的Pcell，也可以是从小区组的Pscell(从小区组的主小区)，除Pcell或者Pscell以外，其他的小区为Scell。 或者，控制信号可以适用于双连接场景的全部小区组，此时的Pcell可以为主小区组的Pcell，除Pcell以外，其他的小区为Scell。
在上述图4所示实施例的基础上，还提供了一种下行通道监听方法。图5是根据一示例性实施例示出的一种下行通道监听方法的流程图，本实施例的交互主体为基站和终端，对根据目标小区范围和目标通道范围确定控制信号生效的目标小区的方式进行说明，如图5所示，包括以下步骤：
在步骤501中，基站向终端发送控制信号，控制信号中携带目标小区范围和目标通道范围。
本公开实施例中，考虑到若分别发送针对每个下行通道的控制信号，会消耗过多的通信资源和电量，因此，通过设置目标小区范围，确定控制信号生效的目标小区。并且，考虑到一个小区中可能包括多个下行通道，为了实现更细粒度的划分，通过设置目标通道范围，确定控制信号生效的目标小区的目标下行通道。
首先，基站通过下行通道向终端发送控制信号，由终端通过该下行通道接收该控制信号。
在一种可能实现方式中，基站为终端配置多个下行通道，可以通过任一个下行通道发送控制信号，该下行通道可以为后续确定的控制信号生效的目标下行通道，也可以是控制信号无效的下行通道。例如，基站可以通过默认BWP(BandWidth Part，带宽部分)、初始BWP、缺省BWP或其他某个BWP，发送控制信号。
在步骤502中，终端接收控制信号，获取控制信号携带的目标小区范围和目标通道范围，根据目标小区范围和目标通道范围，确定目标小区的目标下行通道。
基站向终端发送控制信号时，在控制信号中添加目标小区范围和目标通道范围，目标小区范围用于确定控制信号生效的目标小区，目标通道范围用于确定目标小区的目标下行通道，则终端接收控制信号，即可从控制信号中获取控制信号的目标小区范围和目标通道范围，确定控制信号生效的目标小区以及该目标小区的目标下行通道，将控制信号生效的目标下行通道与其他下行通道加以区分。
终端获取控制信号携带的目标小区范围的方式与上述图4所示实施例类 似，在此不再赘述。
终端获取控制信号携带的目标通道范围的方式包括但不限于以下两种：
第一种，基站在控制信号中添加目标通道范围，则发送的控制信号中携带目标通道范围，终端即可从控制信号中直接获取控制信号的目标通道范围。
在一种可能实现方式中，目标通道范围采用目标通道字段的形式表示，基站在控制信号中添加目标通道字段，目标通道字段包括每个下行通道的指示标识，指示标识用于指示控制信号是否生效。终端接收到控制信号时，获取控制信号的目标通道字段，根据目标通道字段中每个下行通道的指示标识确定控制信号生效的目标下行通道。
目标通道字段中可以包括多个比特位，分别表示多个下行通道的指示标识，指示标识为第一标识时，表示对应的下行通道为控制信号生效的目标下行通道，而指示标识为第二标识时，表示对应的下行通道为控制信号无效的下行通道。
例如，目标下行通道字段中第一个比特位为初始BWP的指示标识，第二个比特位为默认BWP的指示标识，第三个比特位为其他某个BWP的指示标识。指示标识为1，表示对应的下行通道为控制信号生效的目标下行通道，指示标识为0，表示对应的下行通道为控制信号无效的下行通道。
第二种，基站在控制信号中添加第二索引标识，终端接收到控制信号时，获取控制信号携带的第二索引标识，根据第二索引标识查询第二索引表，获取与第二索引标识对应的目标通道范围。
基站可以根据一个或多个可能的目标通道范围创建第二索引表，发送给终端，由终端存储该第二索引表。或者终端可以根据与基站之间的协议确定第二索引表。其中，第二索引表中包括每个第二索引标识对应的目标通道范围，不同的第二索引标识对应不同的目标通道范围，每个目标通道范围内可以包括至少一个目标下行通道。则基站只需向终端发送第二索引标识即可确定对应的目标通道范围，从而根据目标通道范围确定控制信号生效的目标下行通道。此种方式中，无需基站向终端发送目标通道范围本身，节省了通信资源，加快了通信速度。
其中，目标通道范围可以包括控制信号生效的目标下行通道的通道标识，通道标识用于确定对应的下行通道，可以为下行通道所属的BWP、下行通道所在的频段等。目标通道范围可以包括终端所有下行通道的通道标识，或者部 分下行通道的通道标识，可以包括目标小区的所有下行通道，也可以包括目标小区的部分下行通道。且，目标通道范围内可以包括Pcell和至少一个Scell的下行通道的通道标识，表示控制信号适用于包含Pcell的下行通道在内的多个目标下行通道。或者，目标通道范围内还可以不包括Pcell的下行通道的通道标识，表示控制信号适用于全部或部分的Scell的下行通道，而不适用于Pcell的下行通道。
例如，该第二索引表可以如下表2所示，如果第二索引标识为1，则对应的目标通道范围包括BWP1。
表2
第二索引标识 目标通道范围
1 BWP1
2 BWP1，BWP2
3 BWP1，BWP2，BWP3
在一种可能实现方式中，基站可以通过高层信令或者物理层信令等多种方式，向终端发送该第二索引表。
并且，基站可以为所有的终端创建第二索引表，发送给每个终端，后续每个终端可以根据存储的第二索引表进行监听。或者，基站也可以根据每个终端配置的下行通道，单独为每个终端创建第二索引表，将每个终端的第二索引表分别发送给相应的终端，后续每个终端可以根据各自存储的第二索引表进行监听。且不同终端的第二索引表中，目标通道范围可以相同或者不同。
需要说明的是，本公开实施例仅是以控制信号携带目标通道范围为例进行说明，而在另一实施例中，基站为终端配置目标通道范围时，也可以采用其他方式进行配置。
如基站获取目标通道范围，向终端发送目标通道范围，终端存储该目标通道范围。其中基站发送目标通道范围时，可以通过广播消息或者专用信令进行发送。或者，终端根据与基站之间的协议确定目标通道范围，无需基站发送。
或者，基站可以在为终端创建新的下行通道时，向终端发送更新的目标通道范围。创建不同下行通道时基站发送的目标通道范围可以相同，也可以不同。
或者，基站为终端配置多种类型的控制信号，不同类型的控制信号可以包括不同的类型标识，或者采用的加扰方式不同。每次基站在为终端创建新的下行通道时，通过该下行通道发送控制信号的类型，指示终端根据相应类型的控 制信号对该下行通道进行监听。则终端将该下行通道添加至与该控制信号的类型对应的目标通道范围内，接收到控制信号时，确定控制信号的类型对应的目标通道范围，从而确定控制信号生效的目标下行通道。
在步骤503中，终端根据控制信号，对目标下行通道进行监听。
步骤503与上述步骤403类似，在此不再赘述。
本公开实施例通过设置目标通道范围的方式，采用一个唤醒信号即可控制终端在下一个监控时间段对目标小区的全部下行通道或者部分下行通道进行监听，操作简便，简化了基站与终端之间的交互，节省了通信资源。或者，采用一个休眠信号即可控制目标小区的全部下行通道或者部分下行通道进行休眠或者去激活，操作简便，简化了基站与终端之间的交互，节省了通信资源。
例如，基站通过发送一个休眠信号，即可使目标小区从激活的BWP回退到默认BWP或初始BWP，控制终端不再监听激活的BWP，而是监听默认BWP或初始BWP。由于默认BWP或初始BWP的带宽小于其他BWP，因此更为省电。
本公开实施例提供的方法，通过获取控制信号的目标小区范围和目标通道范围，根据目标小区范围和目标通道范围，确定控制信号生效的目标小区及目标小区的目标下行通道，根据控制信号对目标下行通道进行监听。本公开实施例提供了对控制信号生效的目标下行通道进行监听的方式，无需针对每个目标下行通道单独向终端发送控制信号，即可对控制信号生效的目标小区和无效的小区进行区分，对小区中控制信号生效的目标下行通道和无效的下行通道进行区分，进而确定控制信号生效的目标下行通道，不仅节省了通信资源和终端的电量，而且实现了更细粒度的配置，更能够满足通信配置需求。
并且，终端先获取第二索引表，每次基站发送控制信号时，在控制信号中携带第二索引标识，而无需携带目标通道范围本身，终端根据第二索引标识查询第二索引表确定对应的目标通道范围即可，由于第二索引标识的数据量小于目标通道范围的数据量，因此携带第二索引标识的方式减小了数据量，节省通信资源，加快了通信速度。
