Title:
RESOURCE SELECTION METHOD AND APPARATUS FOR SIDELINK TRANSMISSION
Document Type and Number:
WIPO Patent Application WO/2021/002713
Kind Code:
A1
Abstract:
A method performed by a user equipment includes identifying sidelink (SL) resource pool information; determining whether a hybrid automatic repeat request (HARQ) retransmission is configured based on the SL resource pool information; and selecting at least one resource for transmission of a physical sidelink shared channel (PSSCH) based on the determining that the hybrid automatic repeat request (HARQ) retransmission is configured; wherein the at least one resource is determined for ensuring a time gap, based on at least one of a period of resources configured for a physical sidelink feedback channel (PSFCH), an offset between a slot of a PSSCH transmission and a slot of a PSFCH reception, or a time required for reception and processing of the PSFCH plus a time required for SL retransmission preparation.
