Abstract
Disclosed is a method for operating a first device (100) in a wireless communication system. The method may comprise the steps in which: resource selection for a resource included in an active time of a sidelink (SL) discontinuous reception (DRX) configuration is performed on the basis of a second device (200) performing SL communication on the basis of the SL DRX configuration; and information related to the resource selected on the basis of the resource selection is transmitted to the second device (200).
Claims9
A method for performing, by a first device, wireless communication, the method comprising:
- receiving, from a base station, information related to a physical uplink control channel (PUCCH) transmission occasion for sidelink (SL);
- receiving, from the base station, an SL grant related to the PUCCH transmission occasion, including a retransmission resource for a transmission to a second device;
- generating a medium access control (MAC) protocol data unit (PDU) to be retransmitted based on the SL grant;
- obtaining SL discontinuous reception (DRX) configuration of the second device;
- determining that the retransmission resource is not in an active time of the SL DRX configuration;
- and
- transmitting, to the base station, negative acknowledge (NACK) through the PUCCH transmission occasion.
A first device for performing wireless communication, the first device comprising:
- one or more memories storing instructions;
- one or more transceivers;
- and
- one or more processors connected to the one or more memories and the one or more transceivers, wherein the one or more processors execute the instructions to:
- receive, from a base station, information related to a physical uplink control channel (PUCCH) transmission occasion for sidelink (SL);
- receive, from the base station, an SL grant related to the PUCCH transmission occasion, including a retransmission resource for a transmission to a second device;
- generate a medium access control (MAC) protocol data unit (PDU) to be retransmitted based on the SL grant;
- obtain SL discontinuous reception (DRX) configuration of the second device;
- determine that the retransmission resource is not in an active time of the SL DRX configuration;
- and
- transmit, to the base station, negative acknowledge (NACK) through the PUCCH transmission occasion.
A device adapted to control a first user equipment (UE), the device comprising:
- one or more processors;
- and
- one or more memories operably connectable to the one or more processors and storing instructions, wherein the one or more processors execute the instructions to:
- receive, from a base station, information related to a physical uplink control channel (PUCCH) transmission occasion for sidelink (SL);
- receive, from the base station, an SL grant related to the PUCCH transmission occasion, including a retransmission resource for a transmission to a second UE;
- generate a medium access control (MAC) protocol data unit (PDU) to be retransmitted based on the SL grant;
- obtain SL discontinuous reception (DRX) configuration of the second UE;
- determine that the retransmission resource is not in an active time of the SL DRX configuration;
- and
- transmit, to the base station, negative acknowledge (NACK) through the PUCCH transmission occasion.
