背景技术
在第五代移动通信技术(5th-Generation mobile communication technology，5G)新空口(New Radio，NR)通信系统中，每个服务小区(severing cell)上可以配置1个或多个带宽部分(bandwidth part，BWP)。辅小区(Secondary Cell，SCell)具有激活态和去激活态两种状态。在自调度的情况下，一旦SCells被激活，则同时按照该SCell上的相关配置在子载波上进行物理下行控制信道的监听(Physical downlink control channel monitoring，PDCCH monitoring)。当没有业务传输或业务量稀疏时，SCell上持续密集的PDCCH监听而没有数据调度会产生不必要的功耗。协议中，一般通过媒体接入控制(Media Access Control，MAC)的控制单元(Control Element，CE)指示SCell的激活/去激活，在去激活的SCell上，终端不进行PDCCH monitoring以及信道测量、数据接收等操作。但通过MAC CE指示SCell的激活/去激活会带来较大的时延问题，而且频繁的激活/去激活同样会带来不必要的功耗。

可选地，PDCCH最小监听周期表中各个监听周期选项可以选用目前协议中“monitoringSlotPeriodicityAndOffset”的部分选项，例如，选择其中的7个监听周期选项，该7个监听周期选项可以为包含1slot的非连续的选项。
可选地，上述第二信令所指示的最小监听周期，即第二信令中比特指示域指示的索引号对应的最小监听周期，可以仅用于主小区；可选地，第二信令指示的最小监听周期可以用于所有激活的辅小区；可选地，第二信令指示的最小监听周期可以用于主小区和所有激活的辅小区；可选地，第二信令指示的最小监听周期可以用于RRC配置的指定服务小区。

可选地，当第二信令中的比特指示域指示为全0时，可以用于指示最小PDCCH监听周期为1slot的索引号；可选地，当第二信令中的比特指示域指示为全0时，可以用于指示终端当前监听周期的索引号，即不更改当前采用的监听周期。
在上述第二信令指示的情况下，可选地，步骤S202中终端根据第二信令调整控制信道监听周期，可以示例性地执行以下几种方式。
方式一：在当前搜索空间中配置的PDCCH监听周期大于或者大于等于第二信令指示的最小PDCCH监听周期时，终端继续保持当前的监听周期不变。
方式二：在当前搜索空间中配置的PDCCH监听周期小于第二信令指示的最小PDCCH监听周期时，终端确定当前的搜索空间不使能。
方式三：在当前搜索空间中配置的PDCCH监听周期小于第二信令指示的最小PDCCH监听周期时，终端将当前搜索空间配置的PDCCH监听周期调整为第二信令指示的最小PDCCH监听周期，并基于该更新后的监听周期进行监听。
以上方式也即终端实际采用的PDCCH监听周期为第二信令指示的索引号对应的监听周期和当前采用的PDCCH监听周期中较大的监听周期。
方式四：在当前搜索空间中配置的PDCCH监听周期等于第二信令指示的最小PDCCH监听周期时，终端不调整当前的监听周期。
在一种示例中，步骤S201中接收到的第二信令中的比特指示域可以用于指示终端在搜索空间监听周期表中采用的监听周期的索引号。
例如，基站为终端配置一个或多个载波，并为终端的每一个搜索空间配置一个PDCCH监听周期表和offset列表。可选地，该表中可以包含M个PDCCH监听周期，M的取值范围为0～15。
可选地，上述第二信令中的比特指示域可包含X(0≤X≤4)比特。例如，第二信令中比特指示域为“0011”，则表示第二信令中的比特指示域指示搜索空间监听周期表中索引号为3的监听周期。
可选地，上述第二信令所指示的最小监听周期，即第二信令中比特指示域指示的索引号对应的最小监听周期，可以仅用于主小区；可选地，第二信令指示的最小监听周期可以用于所有激活的辅小区；可选地，第二信令指示的最小监听周期可以用于主小区和所有激活的辅小区；可选地，第二信令指示的最小监听周期可以用于RRC配置的指定载波。
可选地，当第二信令中的比特指示域指示为全0(例如，“0000”)时，可以用于指示终端当前监听周期的索引号，即不调整当前的监听周期。可选地，当第二信令中比特指示域指示的索引号超出当前搜索空间中PDCCH监听周期配置时，终端可以不调整搜索空间当前的PDCCH监听周期；可选地，当第二信令中比特指示域指示的索引号超出当前搜索空间中PDCCH监听周期配置时，终端可以采用基站配置的最大的PDCCH监听周期。
基于上述第二信令的指示含义，终端执行上述步骤S202，以调整控制信道监听周期。
在一种示例中，步骤S201中接收到的第二信令中的比特指示域可以用于指示终端的搜索空间的索引号。
例如，基站为终端配置一个或多个载波，并基于配置的载波下发第二信令。

基于第二信令中比特指示域的指示，步骤S202中，终端根据第二信令指示调整控制信道监听周期的方式可以有以下几种。
第一种可选地方式，终端采用搜索空间索引号与第二信令指示的搜索空间索引号相同的搜索空间上采用的PDCCH监听周期作为最小的监听周期。
第二种可选地方式，若其他搜索空间中PDCCH监听周期大于第二信令指示的最小PDCCH监听周期，则终端保持原PDCCH监听周期不变。
第三种可选地方式，若其他搜索空间中PDCCH监听周期小于第二信令指示的最小PDCCH监听周期，则对应的其他搜索空间不使能。
第四种可选地方式，若其他搜索空间中PDCCH监听周期小于第二信令指示的最小PDCCH监听周期，则终端将当前监听周期调整为第二信令指示的最小PDCCH监听周期。例如，当第二信令指示的搜索空间索引号为3，则终端将索引号为3的搜索空间中配置的PDCCH监听周期确定为调整后的PDCCH监听周期。
在上述方式中，也即终端实际采用的PDCCH监听周期为每个搜索空间当前PDCCH监听周期与第二信令指示的搜索空间的采用的监听周期中较大的监听周期。
