Title:
COMMUNICATION METHOD AND COMMUNICATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/156785
Kind Code:
A1
Abstract:
The present application provides a communication method and a communication apparatus, capable of improving service continuity of a terminal in an inter-donor-CU handover scenario. A first centralized unit (CU) of a first donor node determines first mapping, and sends the first mapping to a second CU of a second donor node; the first CU sends downlink data to a second distributed unit (DU) of the second donor node. The first mapping comprises routing mapping and/or bearer mapping; the routing mapping is a mapping relationship between the downlink data and a downlink transmission path; the bearer mapping is a mapping relationship between the downlink data and a downlink transmission bearer; the downlink transmission path comprises a transmission path between the first CU and a target node of downlink data through the second DU; the downlink transmission bearer comprises a radio link control (RLC) channel between the second DU and a first node; the first node is a next hop node of the second DU.
