Title:
METHOD OF DETERMINING PHYSICAL SIDELINK FEEDBACK CHANNEL RESOURCE FOR HYBRID AUTOMATIC REPEAT REQUEST FEEDBACK AND RELATED DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/013180
Kind Code:
A1
Abstract:
A method of determining one or more PSFCH resources for HARQ feedback in sidelink communication for a first UE is disclosed. The method comprises receiving a first SCI for scheduling a first PSSCH transmission, from a second UE, receiving a second SCI for scheduling a second PSSCH transmission, from the second UE, determining priorities of a first HARQ feedback corresponding to the first PSSCH transmission and a second HARQ feedback corresponding to the second PSSCH transmission according to the first SCI and the second SCI, and transmitting a PSFCH for at least one of the first HARQ feedback and the second HARQ feedback with a higher priority according to the determined priorities, to the second UE when a first PSFCH resource for the first HARQ feedback and a second PSFCH resource for the second HARQ feedback are at least overlapped in the time domain.
