Method and apparatus for managing pscell mobility history information in next-generation mobile communication system

Abstract

The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) in a wireless communication system is provided. The method includes entering a radio resource control (RRC) connected mode with a first primary cell (PCell), performing secondary node addition procedure with a primary secondary cell (PSCell), and storing visited information associated with the first PCell and the PSCell in case that the first PCell is changed to a second PCell and the PSCell is released at the same time as the change of the first PCell to the second PCell.

Dependencies are inferred from the claim text.
