Title:
WIRELESS BASE STATION
Document Type and Number:
WIPO Patent Application WO/2024/043154
Kind Code:
A1
Abstract:
Provided is a wireless base station to which selective activation is applied and which can surely execute CPAC even in a case where CPAC is operated partially. The wireless base station comprises: a control unit that controls execution of a secondary cell addition/change procedure; and a transmission unit that, when executing the addition/change procedure, transmits a message including information which is held by a terminal and which is related to a candidate secondary cell of a transition destination, to a transition destination secondary node of the terminal.
