Title:
ENHANCEMENT SCHEME OF PSFCH TRANSMISSION FOR NR SIDELINK COMMUNICATION IN UNLICENSED SPECTRUM
Document Type and Number:
WIPO Patent Application WO/2023/184556
Kind Code:
A1
Abstract:
Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of an enhancement scheme of PSFCH transmission for NR SL communication in unlicensed spectrum. The method comprises receiving, from a second device, a plurality of physical sidelink channels on multiple time instances, wherein the plurality of physical sidelink channels comprise Physical Sidelink Shared Channels (PSSCHs) and/or Physical Sidelink Control Channels (PSCCHs); determining a plurality of Physical Sidelink Feedback Channels (PSFCHs) in a plurality of Physical Resource Blocks (PRBs) within a first slot, wherein the plurality of PSFCHs convey Hybrid Automatic Repeat Request (HARQ) feedbacks corresponding to the plurality of physical sidelink channels; and transmitting, to the second device, the HARQ feedbacks on the plurality of PSFCHs in the plurality of PRBs.
