Title:
METHOD AND APPARATUS USED FOR COMMUNICATION NODE IN WIRELESS COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2023/160415
Kind Code:
A1
Abstract:
Disclosed in the present application are a method and apparatus used for a communication node in wireless communication. A communication node receives a first information block which is used for determining a first resource block; a first signaling is sent in the first resource block, and the first signaling is used for indicating a first index; the first index is one of a plurality of candidate indexes, any one of the plurality of candidate indexes is a non-negative integer; and any one of the plurality of candidate indexes is corresponding to at least one reference signal resource, and uplink transmission out-of-synchronization associated with the reference signal resource corresponding to the first index. To solve the problem that a user equipment cannot recover uplink timing in time, the present application provides a new reporting-based uplink timing recovery solution, in which uplink timing recovery is triggered in time by enabling the user equipment to report uplink timing out-of-synchronization.
