The method is applied to a base station and includes: configuring a first discontinuous reception (DRX) parameter for a terminal for channel monitoring; determining a first power saving signal for indicating the first DRX parameter; sending the first power saving signal to the terminal for the terminal to determine the corresponding first DRX parameter based on the first power saving signal and perform corresponding channel monitoring based on the first DRX parameter. ## Claims ### Claim 1 A channel monitoring method, implemented by a base station, comprising: configuring a first discontinuous reception (DRX) parameter for a terminal for channel monitoring;

a DRX inactivity timer configured to delay the DRX wake-up duration; a short DRX cycle; a long DRX cycle; and a DRX short cycle timer configured to enter the long DRX cycle after the DRX short cycle timer expires. ### Claim 3 (depends on 1) The method of claim 1, wherein determining the first power saving signal for indicating the first DRX parameter comprises: obtaining a binding relationship between power saving signal and DRX parameter; and obtaining the first power saving signal bound to the first DRX parameter from the binding relationship. ### Claim 4 (depends on 3) The method of claim 3, wherein the binding relationship comprises: a one-to-one binding between power saving signal and DRX parameter and/or a many-to-one binding between power saving signal and DRX parameter. ### Claim 5 (depends on 3) The method of claim 3, further comprising: configuring the binding relationship for the terminal; adding the binding relationship to a first system message or first dedicated signaling; and sending the first system message or the first dedicated signaling to the terminal for the terminal to obtain the binding relationship from the first system message or the first dedicated signaling. ### Claim 6 (depends on 1) The method of claim 1, wherein the first power saving signal comprises the first DRX parameter or indication information for characterizing the first DRX parameter. ### Claim 7 (depends on 6) The method of claim 6, further comprising: configuring a DRX candidate parameter set for the terminal;
