Abstract

Apparatuses, methods, and systems are disclosed for sidelink discontinuous reception configuration. One method ( 800 ) includes initiating ( 802 ), by a first user equipment, a sidelink unicast establishment procedure with a second user equipment. The method ( 800 ) includes performing ( 804 ) sidelink communication using a predetermined sidelink discontinuous reception configuration during the sidelink unicast establishment procedure. The method ( 800 ) includes, in response to receiving a direct communication accept message, performing ( 806 ) sidelink communication based on a set of sidelink discontinuous reception configurations.

First claim

The invention claimed is:

1 . A method comprising: A processor for wireless communication, comprising:
at least one controller coupled with at least one memory and configured to cause the processor to:
initiate, by a first user equipment (UE), a sidelink unicast establishment procedure with a second UE;
perform sidelink communication using a predetermined sidelink discontinuous reception (DRX) configuration during the sidelink unicast establishment procedure; and
in response to receiving a direct communication accept message, perform sidelink communication based on a set of sidelink DRX configurations.

2 . The processor of claim 1 , wherein the predetermined sidelink DRX configuration is based on a destination identifier (ID).

3 . The processor of claim 1 , wherein the set of sidelink DRX configurations are associated with a service identifier (ID), PC5 quality of service (QOS) parameters, a PC5 5G QoS ID, QoS flow information, or a combination thereof.

4 . The processor of claim 1 , wherein the set of sidelink DRX configurations correspond to:
a quality of service (QOS) class; an attribute of the QoS class; a range of the attribute of the QoS class; or a combination thereof.

5 . The processor of claim 4 , wherein the quality of service (QOS) class is indicated by a QoS class identifier (ID), PC5 QoS parameters, and a PC5 5G QoS ID, or a combination thereof.

6 . A first user equipment (UE), comprising:
at least one memory; and at least one processor coupled with the at least one memory and configured to cause the first UE to:
initiate a sidelink unicast establishment procedure with a second UE;
perform sidelink communication using a predetermined sidelink discontinuous reception (DRX) configuration during the sidelink unicast establishment procedure; and
in response to receiving a direct communication accept message, perform sidelink communication based on a set of sidelink DRX configurations.

7 . The first UE of claim 6 , wherein the predetermined sidelink DRX configuration is based on a destination identifier (ID).

8 . The first UE of claim 6 , wherein the set of sidelink DRX configurations are associated with a service identifier (ID), PC5 quality of service (QOS) parameters, a PC5 5G QoS ID, QoS flow information, or a combination thereof.

9 . The first UE of claim 6 , wherein the set of sidelink DRX configurations correspond to:
a quality of service (QOS) class; an attribute of the QoS class; a range of the attribute of the QoS class; or a combination thereof.

10 . The first UE of claim 9 , wherein the quality of service (QoS) class is indicated by a QoS class identifier (ID), PC5 QoS parameters, and a PC5 5G QoS ID, or a combination thereof.

11 . A processor for wireless communication, comprising:
at least one controller coupled with at least one memory and configured to cause the processor to:
receive information, at a second user equipment (UE), indicating initiation of a sidelink unicast establishment procedure with a first UE;
perform sidelink communication using a predetermined sidelink discontinuous reception (DRX) configuration during the sidelink unicast establishment procedure; and
in response to transmitting a direct communication accept message, perform sidelink communication based on a set of sidelink DRX configurations.

12 . The processor of claim 11 , wherein the predetermined sidelink DRX configuration is based on a destination identifier (ID).

13 . The processor of claim 11 , wherein the set of sidelink DRX configurations are associated with a service identifier (ID), PC5 quality of service (QOS) parameters, a PC5 5G QoS ID, QoS flow information, or a combination thereof.

14 . The processor of claim 11 , wherein the set of sidelink DRX configurations correspond to:
a quality of service (QOS) class; an attribute of the QoS class; a range of the attribute of the QoS class; or a combination thereof.

15 . The processor of claim 14 , wherein the quality of service (QOS) class is indicated by a QoS class identifier (ID), PC5 QoS parameters, and a PC5 5G QoS ID, or a combination thereof.

16 . A second user equipment (UE), comprising:
at least one memory; and at least one processor coupled with the at least one memory and configured to cause the second UE to:
receive information indicating initiation of a sidelink unicast establishment procedure with a first UE;
perform sidelink communication using a predetermined sidelink discontinuous reception (DRX) configuration during the sidelink unicast establishment procedure; and
in response to transmitting a direct communication accept message, perform sidelink communication based on a set of sidelink DRX configurations.

17 . The second UE of claim 16 , wherein the predetermined sidelink DRX configuration is based on a destination identifier (ID).

18 . The second UE of claim 16 , wherein the set of sidelink DRX configurations are associated with a service identifier (ID), PC5 quality of service (QOS) parameters, a PC5 5G QoS ID, QoS flow information, or a combination thereof.

19 . The second UE of claim 16 , wherein the set of sidelink DRX configurations correspond to:
a quality of service (QOS) class; an attribute of the QoS class; a range of the attribute of the QoS class; or a combination thereof.

20 . The second UE of claim 19 , wherein the quality of service (QOS) class is indicated by a QoS class identifier (ID), PC5 QoS parameters, and a PC5 5G QoS ID, or a combination thereof.
