Title:
DOWNLINK TRANSMISSION TIMING ADJUSTMENT METHOD, AND COMMUNICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/192653
Kind Code:
A1
Abstract:
The present application provides a downlink transmission timing adjustment method. The method comprises: a first node maintains a timer, the timer being used for controlling a time interval between two adjustments of downlink transmission timing, and the downlink transmission timing being a moment that the first node transmits a downlink signal to a second node; if the timer times out, the first node adjusts the downlink transmission timing and restarts the timer; wherein the first node is a relay node in a wireless relay system, and the second node is a sub-node of the first node in the wireless relay system. According to the downlink transmission timing adjustment method provided in the present application, an IAB node is prevented from frequently adjusting the downlink transmission timing, and the accuracy and precision of adjusting the downlink transmission timing by the IAB node are improved.
