wherein the wake-up signal configuration comprises a transmission configuration for indicating one or more transmission parameters based on which the first UE transmits the SL wake-up signal;

determining, by the first UE, a priority of the SL wake-up signal transmitted to the second UE;

determining, by the first UE and based on the transmission configuration and the priority of the SL wake-up signal, to transmit the SL wake-up signal to the second UE or not to transmit the SL wake-up signal to the second UE; and

transmitting, by the first UE, the SL wake-up signal to the second UE, which comprises: transmitting, in response to determining that there are a plurality of to-be-transmitted SL wake-up signals, the plurality of to-be-transmitted SL wake-up signals sequentially in accordance with their priorities.

2 . The method according to claim 1 , wherein the wake-up signal configuration further comprises:

a processing configuration for determining whether to start an on-duration timer when the second UE does not receive the SL wake-up signal transmitted by the first UE.

3 . The method according to claim 1 , wherein the one or more transmission parameters comprise at least one of:

transmission time information for indicating transmission starting time of the SL wake-up signal, wherein the transmission starting time is before starting time of a discontinuous reception (DRX) cycle;

or

a type configuration for indicating a type of the SL wake-up signal, wherein the types of the SL wake-up signal comprise at least one of: a first type of SL wake-up signal that triggers an on-duration timer to be started or a second type of SL wake-up signal that does not trigger the on-duration timer to be started.

4 . The method according to claim 3 , wherein the transmission time information comprises: a transmission time offset for indicating a time offset of the transmission starting time of the SL wake-up signal with respect to the starting time of the DRX cycle.

5 . The method according to claim 3 , further comprising:

transmitting, by the first UE, in response to predicting that no to-be-transmitted SL data occurs for the second UE in a next DRX cycle, the second type of SL wake-up signal to the second UE at the transmission starting time.

6 . The method according to claim 1 , wherein determining, by the first UE, the priority of the SL wake-up signal transmitted to the second UE comprises at least one of:

determining, based on a highest priority of logical channels that are associated with the second UE and have a data transmission, the priority of the SL wake-up signal;

determining, based on a lowest priority of all logical channels that are associated with the second UE, the priority of the SL wake-up signal;

configuring a corresponding priority of the SL wake-up signal for each second UE;

obtaining the priority of the SL wake-up signal configured by a network for each second UE; or

determining, based on a communication protocol, the priority of the SL wake-up signal.

7 . The method according to claim 1 , wherein determining to transmit the SL wake-up signal to the second UE or not to transmit the SL wake-up signal to the second UE is further based on a priority of a Uu signal that has a resource conflict with the SL wake-up signal.

8 . The method according to claim 7 , wherein determining to transmit the SL wake-up signal to the second UE comprises:

transmitting, in response to determining that the priority of the SL wake-up signal is higher than a priority threshold of the SL wake-up signal and the priority of the Uu signal is lower than a priority threshold of the Uu signal, the SL wake-up signal to the second UE; and

wherein determining not to transmit the SL wake-up signal to the second UE comprises:

transmitting, in response to determining that the priority of the SL wake-up signal is lower than or equal to a priority threshold of the SL wake-up signal, the Uu signal rather than the SL wake-up signal to the second UE;

transmitting, in response to determining that the priority of the Uu signal is higher than or equal to a priority threshold of the Uu signal, the Uu signal rather than the SL wake-up signal to the second UE; and

transmitting, in response to determining that the priority of the SL wake-up signal is lower than or equal to the priority threshold of the SL wake-up signal and the priority of the Uu signal is higher than or equal to the priority threshold of the Uu signal, the Uu signal rather than the SL wake-up signal to the second UE.

9 . The method according to claim 1 , wherein the priority of the first type of SL wake-up signal and the priority of the second type of SL wake-up signal are determined in different ways.

10 . The method according to claim 1 , comprising:

receiving, by the second UE, the SL control signaling that carries the wake-up signal configuration from the first UE; and

monitoring, by the second UE and based on the wake-up signal configuration, the SL wake-up signal from the first UE.

11 . The method according to claim 10 , wherein the wake-up signal configuration further comprises:

a processing configuration for determining whether to start an on-duration timer when the second UE does not receive the SL wake-up signal transmitted by the first UE.
