METHOD AND DEVICE FOR PERFORMING SL DRX OPERATION IN NR V2X ON BASIS OF HARQ FEEDBACK - A simplified explanation of the abstract
This abstract first appeared for US patent application 18269397 titled 'METHOD AND DEVICE FOR PERFORMING SL DRX OPERATION IN NR V2X ON BASIS OF HARQ FEEDBACK
Simplified Explanation
The abstract describes a method for a first device to perform wireless communication, specifically related to sidelink communication.
- Acquiring an SL DRX configuration including information about a sidelink discontinuous reception cycle and active time.
- Transmitting sidelink control information (SCI) to a second device through a physical sidelink control channel (PSCCH) for scheduling a physical sidelink control channel (PSSCH).
- Transmitting second SCI and a medium access control protocol data unit (PDU) to the second device through the PSSCH.
- Determining a physical sidelink feedback channel (PSFCH) resource based on the index of a slot related to the PSSCH and a subchannel index.
- Receiving a hybrid automatic repeat request (HARQ) feedback for the MAC PDU from the second device on the basis of the PSFCH resource.

Original Abstract Submitted
Proposed is a method for a first device to perform wireless communication according to an embodiment. The method may comprise the steps of: acquiring an SL DRX configuration including information related to a sidelink discontinuous reception (SL DRX) cycle and information related to an active time; transmitting first sidelink control information (SCI) to a second device through a first physical sidelink control channel (PSCCH), wherein the first sidelink control information (SCI) is for scheduling a first physical sidelink control channel (PSSCH); transmitting second SCI and a first medium access control (MAC) protocol data unit (PDU) to the second device through the first PSSCH; determining a first physical sidelink feedback channel (PSFCH) resource in the first PSFCH slot on the basis of an index of a slot related to the first PSSCH and an index of a subchannel; and receiving a first hybrid automatic repeat request (HARQ) feedback for the first MAC PDU, the first HARQ feedback being received from the second device on the basis of the first PSFCH resource. For example, the first PSFCH slot may be included in an inactive time at the time of transmission of the first MAC PDU. For example, the first PSFCH slot may be included in an active time at the time of reception of the first HARQ feedback.
