下面先从基站侧介绍一下本公开提供的信道监听方法。
本公开实施例提供了一种信道监听方法，参照图1所示，图1是根据一实施例示出的一种信道监听方法流程图，可以用于基站，该方法可以包 括以下步骤：
在步骤101中，广播至少一个配置信息。
在本公开实施例中，配置信息用于配置非连续发送PDCCH(Physical Downlink Control Channel，物理下行控制信道)的一个周期时长。基站广播多个配置信息的情况下，每个配置信息所配置的非连续发送PDCCH的周期时长可以不同。
在一个可能的实现方式中，基站可以广播包括至少一个配置信息的系统消息。
在步骤102中，确定进入非连续发送PDCCH的节能发送模式。
在一个可能的实现方式中，基站可以在系统低负荷的情况下，确定进入该非连续发送PDCCH的节能发送模式。其中，系统低负荷的情况包括但不限于系统负载较低，和/或系统业务量较少的情况。
在步骤103中，向处于连接态的终端发送第一指示信息。
在本公开实施例中，第一指示信息用于激活至少一个所述配置信息中的第一配置信息。
在一个可能的实现方式中，第一指示信息可以为DCI(Downlink Control Information，下行控制信息)。即基站通过DCI将生效的第一配置信息告知终端。可选地，第一指示信息可以包括但不限于寻呼DCI，基于PEI(Permanent Equipment Identifier，永久设备标识符)的DCI。
例如，基站广播了3个配置信息，对应配置的非连续发送PDCCH的周期时长分别为t 1、t 2和t 3。基站在进入节能发送模式后，通过第一指示信息，即DCI指示激活上述3个配置信息中的第一配置信息，假设第一配置信息对应的周期时长为t 3，则终端会按照周期时长t 3，非连续监听PDCCH。
上述实施例中，基站可以先广播至少一个配置信息，配置信息用于配置非连续发送物理下行控制信道PDCCH的一个周期时长。进一步地，基站在进入非连续发送PDCCH的节能发送模式后，向处于连接态的终端发送第一指示信息，通过第一指示信息激活至少一个配置信息中的第一配置 信息。终端可以基于第一配置信息，非连续监听PDCCH。本公开中，基站可以非连续发送PDCCH，达到了节省基站能耗的目的。
在一些可选实施例中，参照图2所示，图2是根据一实施例示出的一种信道监听方法流程图，可以用于基站，该方法可以包括以下步骤：
在步骤201中，广播至少一个配置信息。
在本公开实施例中，配置信息用于配置非连续发送PDCCH的一个周期时长。基站广播多个配置信息的情况下，每个配置信息所配置的非连续发送PDCCH的周期时长可以不同。
在一个可能的实现方式中，基站可以广播包括至少一个配置信息的系统消息。
在步骤202中，确定进入非连续发送PDCCH的节能发送模式。
在步骤203中，向处于连接态的终端发送第一指示信息。
在本公开实施例中，第一指示信息用于激活至少一个所述配置信息中的第一配置信息。
在一个可能的实现方式中，第一指示信息可以为DCI。即基站通过DCI将生效的第一配置信息告知终端。
在步骤204中，确定激活至少一个所述配置信息中的第二配置信息。
在本公开实施例中，第二配置信息与之前已经激活的第一配置信息可以不同。
在步骤205中，向所述处于连接态的终端发送第二指示信息。在本公开实施例中，所述第二指示信息用于激活所述第二配置信息。
