Title:
METHOD AND APPARATUS FOR CONFIGURING CANDIDATE PSCELL DURING CONDITIONAL HANDOVER IN NEXT-GENERATION MOBILE COMMUNICATION
Document Type and Number:
WIPO Patent Application WO/2024/034882
Kind Code:
A1
Abstract:
The present invention relates to a method of a first base station, comprising the steps of: determining whether or not to perform conditional handover (CHO) and conditional PSCell addition and change (CPAC) for a terminal; transmitting, to a candidate target base station of the CHO, a handover request message including an indicator for the CHO and an indicator regarding performance of the CPAC; receiving, from the candidate target base station, a handover response message including configuration information for performing the CPAC; and transmitting, to the terminal, on the basis of the configuration information, a radio resource control (RRC) reconfiguration message including conditional reconfiguration information for performing the CHO and the CPAC, wherein the conditional reconfiguration information includes a configuration for the candidate target base station and a configuration for each of at least one candidate secondary cell group related to the CPAC.
