Title:
METHOD AND DEVICE IN NODE USED FOR WIRELESS COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2020/233405
Kind Code:
A1
Abstract:
Disclosed in the present application are a method and device in a node for wireless communication. A first node monitors first information in a first time-frequency resource pool; executes channel sensing in a first time-frequency resource group and obtains a first measured value; if the first measured value is greater than a target threshold, determines that a second time-frequency resource block does not belong to a first candidate resource block set, or otherwise, determines that the second time-frequency resource block belongs to the first candidate resource block set. The first information indicates that a third time-frequency resource block is reserved for first control information; the first control information is used for indicating whether a first transmission block is correctly received; the second time-frequency resource block comprises the third time-frequency resource block. The target threshold is related to whether the first information is detected in the first time-frequency resource pool. The first time-frequency resource group is associated with the second time-frequency resource block. The above-mentioned method ensures the transmission reliability of PSFCH, and improves resource utilization.
