Title:
METHOD AND APPARATUS FOR USE IN NODE FOR WIRELESS COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2021/077961
Kind Code:
A1
Abstract:
Disclosed are a method and apparatus for use in a node for wireless communication. A first node receives first signaling and a first signal in a first time-frequency resource block, and sends a second signal in a first radio resource block. The first signaling comprises scheduling information of the first signal; the first signal carries a first bit block set; the first time-frequency resource block is used for determining the first radio resource block; the second signal carries a second bit block, and the second bit block indicates whether the first bit block set is correctly received; the second bit block comprises binary bits of which the number is a positive integer, and the number of the binary bits comprised in the second bit block is related to the size of a frequency-domain resource occupied by the first time-frequency resource block. According to the method, the utilization rate of PSFCH resources in sidelink communication is improved, and signaling overhead is not increased.
