Method and device for informing about whether SL DRX operation is supported in NR V2X

1 . A method, comprising:

obtaining, by a first user equipment (UE), an inter-UE discontinuous reception (DRX) configuration including information related to a timer related to an active time;

determining, by the first UE, deactivation of inter-UE DRX operation related to the inter-UE DRX configuration, based on that at least one UE transmitting a service of interest to the first UE does not support the inter-UE DRX operation; and

based on the determination, transmitting, by the first UE to a second UE, information representing that the first UE keeps an active state,

wherein the information related to the timer related to the active time is information related to an inter-UE DRX onduration timer, information related to an inter-UE DRX inactivity timer, or information related to an inter-UE DRX retransmission timer.

2 . The method of claim 1 , further comprising:

establishing, by the first UE, a radio resource control (RRC) connection between the first UE and the second UE.

3 . The method of claim 2 , wherein, based on that the RRC connection is established between the first UE and the second UE, the inter-UE DRX configuration including the information related to the timer related to the active time is received from the second UE.

4 . The method of claim 1 , wherein, based on that data of interest to the first UE does not support the inter-UE DRX operation, the deactivation of the inter-UE DRX operation is determined by the first UE.

5 . The method of claim 1 , wherein, based on that data of interest to the first UE is related to the deactivation of the inter-UE DRX operation, the deactivation of the inter-UE DRX operation is determined by the first UE.

6 . The method of claim 1 , wherein, based on that a destination identifier (ID) of interest to the first UE does not support the inter-UE DRX operation, the deactivation of the inter-UE DRX operation is determined by the first UE.

7 . The method of claim 1 , wherein, based on that a destination identifier (ID) of interest to the first UE is related to the deactivation of the inter-UE DRX operation, the deactivation of the inter-UE DRX operation is determined by the first UE.

8 . The method of claim 1 , wherein, based on that a source identifier (ID) of interest to the first UE does not support the inter-UE DRX operation, the deactivation of the inter-UE DRX operation is determined by the first UE.

9 . The method of claim 1 , wherein, based on that a source identifier (ID) of interest to the first UE is related to the deactivation of the inter-UE DRX operation, the deactivation of the inter-UE DRX operation is determined by the first device UE.

10 . The method of claim 1 , wherein, based on that a bearer related to data intended to be received by the first UE does not support the inter-UE DRX operation, the deactivation of the inter-UE DRX operation is determined by the first UE.

11 . The method of claim 1 , wherein, based on that a bearer related to data intended to be received by the first UE is related to the deactivation of the inter-UE DRX operation, the deactivation of the inter-UE DRX operation is determined by the first UE.

12 . A first UE, comprising:

at least one transceiver;

at least one processor; and

at least one memory connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, cause the first UE to perform operations comprising:

obtaining an inter-UE discontinuous reception (DRX) configuration including information related to a timer related to an active time;

determining deactivation of inter-UE DRX operation related to the inter-UE DRX configuration, based on that at least one UE transmitting a service of interest to the first UE does not support the inter-UE DRX operation; and

based on the determination, transmitting, to a second UE, information representing that the first UE keeps an active state,

wherein the information related to the timer related to the active time is information related to an inter-UE DRX onduration timer, information related to an inter-UE DRX inactivity timer, or information related to an inter-UE DRX retransmission timer.

13 . The first UE of claim 12 , wherein, based on that data of interest to the first UE does not support the inter-UE DRX operation, the deactivation of the inter-UE DRX operation is determined by the first UE.

14 . The first UE of claim 12 , wherein, based on that data of interest to the first UE is related to the deactivation of the inter-UE DRX operation, the deactivation of the inter-UE DRX operation is determined by the first UE.

15 . A processing device, comprising:

at least one processor; and

at least one memory connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, cause a first UE to perform operations comprising:

obtaining an inter-UE discontinuous reception (DRX) configuration including information related to a timer related to an active time;

determining deactivation of inter-UE DRX operation related to the inter-UE DRX configuration, based on that at least one UE transmitting a service of interest to the first UE does not support the inter-UE DRX operation; and

based on the determination, transmitting, to a second UE, information representing that the first UE keeps an active state,

wherein the information related to the timer related to the active time is information related to an inter-UE DRX onduration timer, information related to an inter-UE DRX inactivity timer, or information related to an inter-UE DRX retransmission timer.

16 . The processing device of claim 15 , wherein, based on that data of interest to the first UE does not support the inter-UE DRX operation, the deactivation of the inter-UE DRX operation is determined by the first UE.
