Title:
METHOD AND DEVICE FOR ALLOCATING SL HARQ FEEDBACK REPORT RESOURCE IN NR V2X
Document Type and Number:
WIPO Patent Application WO/2021/029722
Kind Code:
A1
Abstract:
A method by which a first device performs wireless communication and a device for supporting same are provided. The method comprises the steps of: receiving, from a base station, downlink control information (DCI) for scheduling a sidelink (SL) resource, through a physical downlink control channel (PDCCH), the DCI including information related to the time between a physical sidelink feedback channel (PSFCH) resource and a physical uplink control channel (PUCCH) resource and information related to the PUCCH resource; transmitting, to a second device, a plurality of physical sidelink control channels (PSCCHs) and a plurality of physical sidelink shared channels (PSSCHs) on the basis of the DCI; determining a plurality of PSFCH resources on the basis of the index of a slot related to the plurality of PSSCHs, the index of a sub channel related to the plurality of PSSCHs, and a source ID of the first device; receiving, from the second device, a plurality of pieces of SL HARQ feedback related to the plurality of PSSCHs, on the plurality of PSFCH resources; and transmitting, to the base station, one piece of SL hybrid automatic repeat request (HARQ) feedback on one PUCCH resource, on the basis of the information related to the PUCCH resource and the information related to the time, wherein the one PUCCH resource can be allocated after the last PSFCH resource from among the plurality of PSFCH resources.
