Title:

COMMUNICATION SYSTEM AND BASE STATION

Document Type and Number:

WIPO Patent Application WO/2022/255133

Kind Code:

A1

Abstract:

This communication system comprises a first base station composed of a central unit (IAB-Donor CU) and a distributed unit (IAB-Donor DU) and operating as an integrated access backhaul donor, and at least one second base station operating as an integrated access backhaul node (IAB-node). The central unit performs, with respect to the distributed unit and the second base station, address configuration for multicasting data from the central unit to a communication terminal in a backhaul adaptation layer in which data transmitted and received to and from the communication terminal is routed.
