The method is applicable to a base station. The base station configures a corresponding designated DRX parameter for a designated BWP. The base station configures at least one bandwidth part (BWP) for a terminal. The base station generates a DRX configuration information for indicating that the designated DRX parameter is to be used on the designated BWP. The base station sends the DRX configuration information to the terminal for the terminal to use the designated DRX parameter on the designated BWP based on the DRX configuration information. ## Claims ### Claim 1 A method for discontinuous reception (DRX) configuration applied to a base station and comprising: configuring a corresponding designated DRX parameter for a designated bandwidth part (BWP), wherein the base station configures at least one BWP for a terminal;

adding the binding relationship to the DRX configuration information; and sending the DRX configuration information carrying the binding relationship to the terminal. ### Claim 3 (depends on 2) The method of claim 2, wherein the binding relationship comprises at least one of: a one-to-one correspondence between BWP and DRX parameter, or a many-to-one correspondence between BWP and DRX parameter. ### Claim 4 (depends on 2) The method of claim 2, wherein sending the DRX configuration information carrying the binding relationship to the terminal comprises: adding the DRX configuration information 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 DRX configuration information from the first system message or the first dedicated signaling. ### Claim 5 (depends on 1) The method of claim 1, wherein sending the DRX configuration information to the terminal comprises: generating a BWP switching command for carrying the DRX configuration information, wherein the DRX configuration information comprises a target DRX parameter corresponding to a target BWP or indication information for characterizing the target DRX parameter corresponding to the target BWP, wherein the designated BWP is the target BWP to which the base station instructs the terminal to switch a BWP; and sending the BWP switching command to the terminal. ### Claim 6 (depends on 5) The method of claim 5, further comprising: configuring a candidate parameter set for the terminal; adding the DRX candidate parameter set to a second system message or second dedicated signaling; and sending the second system message or the second dedicated signaling to the terminal for the terminal to obtain the DRX candidate parameter set from the second system message or the second dedicated signaling, and determine the target DRX parameter corresponding to the target BWP based on the DRX candidate parameter set and the indication information in the DRX configuration information. ### Claim 7 (depends on 1) The method of claim 1, wherein sending the DRX configuration information to the terminal comprises: generating a third system message or third dedicated signaling for carrying the DRX configuration information, wherein the DRX configuration information comprises at least one of a first default DRX parameter corresponding to a default BWP, or a second default DRX parameter corresponding to an initial BWP, and wherein the designated BWP comprises at least one of the default BWP for implementing an automatic BWP fall back function or the initial BWP for implementing the automatic BWP fall back function; and sending the third system message or the third dedicated signaling to the terminal. ### Claim 8 A method for discontinuous reception (DRX) configuration applied to a terminal and comprising: receiving DRX configuration information sent by a base station, wherein the DRX configuration information indicates that a designated DRX parameter is to be used on a designated bandwidth part (BWP), wherein the base station configures at least one BWP for the terminal;
