Document Type and Number:
WIPO Patent Application WO/2023/224132
Kind Code:
A1
Abstract:
Provided are a method for beam tracking performed by a mobile node in a wireless communication system, and a device using the method. The mobile node performs one of SSB/CSI-RS-based beam tracking and beam index-based beam tracking according to a configured mode. In the beam index-based beam tracking, the mobile node and a fixed node exchange beam tables with each other, and the mobile node provides a beam index of a first time point to the fixed node. Thereafter, when a movement event occurs in the mobile node, the mobile node determines a beam index of a second time point in consideration of the beam table of the fixed node and a predicted location of the mobile node due to the movement event, and then provides the determined beam index to the fixed node.
