Title:
METHOD AND DEVICE USED IN NODE FOR WIRELESS COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2021/093512
Kind Code:
A1
Abstract:
Disclosed in the present application are a method and device used in a node for wireless communication. A first node receives a first signaling and a first signal in a first time-frequency resource block, and transmits a second information block in a first air interface resource block. The first signaling comprises scheduling information of the first signal; the first signal carries a first bit block set; the second information block indicates whether the first bit block set is correctly received; the first air interface resource block belongs to a first air interface resource block group; the first time-frequency resource block is used to determine a first time-frequency unit; a first time-frequency unit group comprises the first time-frequency unit and at least one other time-frequency unit, and any two time-frequency units in the first time-frequency unit group are orthogonal in the time domain; and the first time-frequency unit group is used to determine the first air interface resource block group. The described method achieves HARQ-ACK multiplexing in a sidelink, improves the resource utilization of a feedback channel, and simplifies the design of a feedback channel.
