Title:
CENTRAL UNIT, DISTRIBUTION UNIT, WIRELESS ACCESS NETWORK NODE, UE, AND METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2024/024460
Kind Code:
A1
Abstract:
This central unit CU (301) receives, from a first distributed unit (DU) (302), a first message pertaining to the preparation of layer 1 or layer 2 (L1/L2) base/inter-cell mobility of a UE. The L1/L2 base/inter-cell mobility is intra-DU L1/L2 base/inter-cell mobility within the first DU (302) or intra-DU L1/L2 base/inter-cell mobility from the first DU (302) to a second DU. After receiving the first message, the CU (301) transmits, to the first DU (302), a second message pertaining to the preparation of L1/L2 base/inter-cell mobility. This contributes to make it possible to perform, for example, the preparation of L1/L2 base/inter-cell mobility between the source distribution unit (DU) and the central unit (CU).
