1. A method for downlink channel monitoring, applied to a terminal, and the method comprising:
receiving a control signal sent through a secondary downlink channel from a base station, and acquiring a target cell range of the control signal, wherein the target cell range is configured to determine a target cell for which the control signal takes effect;
determining a target downlink channel of the target cell according to the target cell range; and
monitoring the target downlink channel according to the control signal,
wherein the control signal is a sleep signal, and the sleep signal is used to make the target cell fall back from an activated BandWidth Part to a default BandWidth Part or an initial BandWidth Part, where a bandwidth of the default BandWidth Part or the initial BandWidth Part is smaller than that of other BandWidth Parts,
wherein monitoring the target downlink channel according to the control signal comprises:
stopping monitoring the activated BandWidth Part of the target cell, and monitoring the default BandWidth Part or the initial BandWidth Part of the target cell,
wherein acquiring the target cell range of the control signal comprises:
acquiring a first index identifier carried by the control signal, wherein an amount of data of the first index identifier is less than an amount of data of the target cell range,
querying a first index table according to the first index identifier; and
acquiring a target cell range corresponding to the first index identifier.
