Title:
DEVICE AND METHOD FOR CHANGING PRIMARY CELL IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/072002
Kind Code:
A1
Abstract:
The present disclosure relates to a device and method for changing a primary cell (Pcell) in a wireless communication system. The operation method of a terminal may comprise the steps of: performing a random access procedure with a base station; configuring a first cell among cells of the base station as the Pcell; configuring a second cell among the cells of the base station as a secondary cell (SCell); receiving an instruction to change the Pcell to the second cell; and, when the second cell is in an inactivation state or an active bandwidth part (BWP) of the terminal is dormant in the second cell, changing the Pcell to a third cell different from the second cell or switching the active BWP and then changing the Pcell to the second cell.
