Title:
OPERATION METHOD OF DU OF PARENT NODE COMMUNICATING WITH MT OF IAB NODE IN WIRELESS COMMUNICATION SYSTEM, AND DEVICE USING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/177767
Kind Code:
A1
Abstract:
Provided are an operation method performed by a first distributed unit (DU) of a first parent node communicating with a mobile terminal (MT) of an IAB node in a wireless communication system, and a device using the method. The first parent node acquires first configuration information about the first DU, acquires second configuration information about a second DU of a second parent node communicating with the MT, and restricts, on the basis of the first configuration information and the second configuration information, downlink transmission or uplink reception operations of the first DU if predetermined conditions are satisfied.
