Abstract

Claims (40)

1 . A method for controlling a state, comprising:

waking up within a wake up period of a discontinuous reception (DRX) cycle corresponding to a wake up signal whose signal monitoring resource is occupied in absence of detecting the wake-up signal, in response to determining that the signal monitoring resource of the wake up signal of a sidelink is occupied;

setting a monitoring timer in a sleep period, in response to determining that a channel monitoring resource of a communication channel of the sidelink is occupied so that a user equipment (UE) is unable to receive data during the wake up period; and

waking up within a timing duration of the monitoring timer within the sleep period, and monitoring the communication channel of the sidelink to receive data retransmitted during the sleep period.

2 . The method of claim 1 , wherein the signal monitoring resource of the wake up signal of a sidelink is occupied comprises at least one of following acts:

occupying the signal monitoring resource of the wake up signal due to an uplink transmission resource of a Uu interface;

occupying the signal monitoring resource of the wake up signal due to a bandwidth part (BWP) switching interruption; or

occupying the signal monitoring resource of the wake up signal due to a measurement resource used for a wireless signal measurement.

3 . The method of claim 1 , wherein waking up within the DRX cycle corresponding to the wake up signal whose signal monitoring resource is occupied comprises:

starting a first wake up timer in the DRX cycle corresponding to the wake up signal whose signal monitoring resource is occupied; and

waking up within a timing duration of the first wake up timer.

4 . The method of claim 1 , wherein setting the monitoring timer in the sleep period, in response to determining that the channel monitoring resource of the communication channel of the sidelink is occupied comprises:

setting the monitoring timer in the sleep period, in response to determining that a channel monitoring resource of the communication channel of the sidelink is occupied within a timing duration of a second wake up timer located before and adjacent to the sleep period, or within a timing duration of an inactivity timer located before and adjacent to the sleep period.

5 . The method of claim 4 , wherein the channel monitoring resource of the communication channel of the sidelink is occupied within the timing duration of the second wake up timer located before and adjacent to the sleep period, or within the timing duration of the inactivity timer located before and adjacent to the sleep period comprises:

occupying all the channel monitoring resource or part of the channel monitoring resource within the timing duration of the second wake up timer due to an uplink transmission on a Uu interface or a wireless signal measurement;

or

occupying all the channel monitoring resource or part of the channel monitoring resource within the timing duration of the inactivity timer due to the uplink transmission or the wireless signal measurement of the Uu interface.

6 . The method of claim 5 , wherein occupying part of the channel monitoring resource within the timing duration of the second wake up timer due to the uplink transmission on the Uu interface or the wireless signal measurement comprises at least one of:

occupying the channel monitoring resource within a first duration before a timing end moment of the second wake up timer due to the uplink transmission or the wireless signal measurement of the Uu interface;

or

occupying the channel monitoring resource with a time domain width in the timing duration of the second wake up timer due to the uplink transmission or the wireless signal measurement of the Uu interface, wherein a proportion of the time domain width to the timing duration of the second wake up timer is greater than a proportional threshold;

occupying part of the channel monitoring resource within the timing duration of the inactivity timer due to the uplink transmission on the Uu interface or the wireless signal measurement comprises at least one of:

occupying the channel monitoring resource within a first duration before a timing end moment of the inactivity timer due to the uplink transmission or the wireless signal measurement of the Uu interface;

or

occupying the channel monitoring resource with a time domain width in the timing duration of the inactivity timer due to the uplink transmission on the Uu interface or the wireless signal measurement, wherein a proportion of the time domain width to the timing duration of the inactivity timer is greater than a proportional threshold.

7 . The method of claim 6 , further comprising at least one of following steps:

receiving a radio resource control (RRC) signaling of the Uu interface carrying indication information indicating the first duration;

receiving a RRC signaling of the sidelink carrying indication information indicating the first duration;

receiving the RRC signaling of the Uu interface carrying indication information indicating the proportion threshold; or

receiving the RRC signaling of the sidelink carrying indication information indicating the proportion threshold.

8 . The method of claim 1 , wherein the monitoring timer comprises an inactivity timer.

9 . The method of claim 8 , further comprising at least one of following steps:

receiving the RRC signaling of the Uu interface carrying an indication indicating a configuration for the monitoring timer; or

receiving the RRC signaling of the sidelink carrying the indication indicating the configuration for the monitoring timer.

10 . The method of claim 1 , wherein setting the monitoring timer in the sleep period comprises:

setting the monitoring timer at the start moment of the sleep period.

11 . A communication device, comprising a processor, a transceiver, a memory and an executable program stored in the memory and capable of running by the processor, when the processor executes the executable program, the processor is configured to:

wake up within a wake up period of a discontinuous reception (DRX) cycle corresponding to a wake up signal whose signal monitoring resource is occupied in absence of detecting the wake-up signal, in response to determining that the signal monitoring resource of the wake up signal of a sidelink is occupied;

set a monitoring timer in a sleep period, in response to determining that a channel monitoring resource of a communication channel of the sidelink is occupied so that a user equipment (UE) being unable to receive data during the wake-up period; and

wake up within a timing duration of the monitoring timer within the sleep period, and monitoring the communication channel of the sidelink to receive data retransmitted during the sleep period.
