whether disabling a DRX function of the second DRX group is supported; or

suggestion information on whether the second DRX group needs to enter the wake-up state.

5 . The method according to claim 1 , wherein transmitting the wake-up notification to the first DRX group in the wake-up state in the UE comprises:

transmitting the wake-up notification to the first DRX group in the wake-up state in the UE, in response to determining that cache data volume for the UE is greater than a cache threshold.

6 . The method according to claim 1 , wherein the wake-up notification further comprises

a group identifier of a DRX group that receives the wake-up notification.

7 . The method according to claim 1 , wherein

a start time of the wake-up time corresponding to the wake-up notification comprises a reception time when the UE receives the wake-up notification, and

an end time of the wake-up time corresponding to the wake-up notification comprises:

a reception time when the UE receives a transmission instruction for data transmission; or

a time when the UE completes the reception of service data, wherein the transmission instruction or the service data is transmitted from the base station after the wake-up notification.

8 . The method according to claim 1 , wherein disabling the DRX function of the DRX group indicates that the DRX group continues or starts to perform PDCCH monitoring for a timer duration.

9 . The method according to claim 1 , wherein the wake-up notification is further configured to indicate a duration of disabling the DRX function of the second DRX group, and the DRX function of the second DRX group is re-enabled in response to determining that an actual duration of disabling the second DRX group reaches the duration.

10 . The method according to claim 1 , wherein the first DRX group is a DRX group of a primary cell, and the second DRX group is a DRX group of a secondary cell; or

the second DRX group is the DRX group of the primary cell, and the first DRX group is the DRX group of the secondary cell.

11 . A method for wake-up for discontinuous reception (DRX), performed by a user equipment (UE), the method comprising:

receiving, using a first DRX group in a wake-up state, a wake-up notification for a second DRX group; and

waking up the second DRX group in advance according to the wake-up notification;

wherein waking up the second DRX group in advance according to the wake-up notification comprises at least one of:

waking up the second DRX group in advance by starting or restarting an IAT of the second DRX group;

waking up the second DRX group in advance by exiting a long DRX cycle of a DRX group and entering a short DRX cycle;

disabling a DRX function of the second DRX group according to the wake-up notification; or

enabling the second DRX group to enter a wake-up time corresponding to the wake-up notification according to the wake-up notification;

wherein the wake-up notification is transmitted from a base station on a time-frequency resource scheduled for the first DRX group and is configured to carry a group identifier of the second DRX group; and the wake-up notification is multicast to the first DRX group, and the multicast of the wake-up notification is for a UE group.

12 . The method according to claim 11 , wherein the wake-up notification is carried in radio resource control (RRC) signaling, a medium access control control element (MAC CE), or downlink control information (DCI).

13 . The method according to claim 11 , further comprising:

reporting auxiliary information, wherein the wake-up notification is determined according to the auxiliary information.

14 . The method according to claim 13 , wherein the auxiliary information comprises at least one of:

timer information of an inactivity timer of the second DRX group;

cycle information of a short DRX cycle of the second DRX group;

whether disabling a DRX function of the second DRX group is supported; and

suggestion information on whether the second DRX group needs to enter the wake-up state.

15 . A communication device, comprising:

a transceiver,

a memory that stores an executable program,

one or more processors that are communicatively coupled to the transceiver and the memory,

wherein the one or more processors are collectively configured to:

transmit a wake-up notification to a first discontinuous reception (DRX) group in a wake-up state in a user equipment (UE), wherein the wake-up notification is at least configured to wake up a second DRX group in a dormant state in the UE in advance and carry a group identifier of the second DRX group, and the wake-up notification is transmitted from the base station on a time-frequency resource scheduled for the first DRX group;

wherein the wake-up notification is configured to at least one of:
