Title:
METHOD AND DEVICE USED IN COMMUNICATION NODE FOR WIRELESS COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2022/156724
Kind Code:
A1
Abstract:
The present application discloses a method and device used in a communication node for wireless communication. The method comprises: a communication node receiving first signaling, the first signaling being used for determining K1 preamble resource groups; determining a first load; determining a first preamble resource group subset among the K1 preamble resource groups according to the size of the first load; selecting a first preamble resource from the first preamble resource group subset, and sending a first message; receiving a second message; and sending a third message on a first resource pool; the first message being associated with the first preamble resource; a first condition set being used for determining whether the first load comprises a first sub-load, the first sub-load being not excluded by the first resource pool, and the K1 being a positive integer not less than 1; the first condition set being related to a logical channel; the third message carrying all or part of the first load; and the size of the first resource pool being related to the first preamble resource group subset.
