Abstract

Provided is an apparatus and method for performing activation / deactivation of a serving cell in a wireless communication system supporting dual connectivity. The method for performing activation / deactivation of serving cell by a user equipment in a wireless communication system includes configuring a dual connectivity with at least two different base stations based on dual connectivity configuration information received through RRC (Radio Resource Control) message from a base station, receiving activation / deactivation information about secondary serving cell configured for the UE from each of two different base stations, and selectively applying the activation / deactivation information about the secondary serving cell configured for the UE based on information including the secondary serving cell provided by the base station or information about the base station providing the secondary serving cell configured for the UE.

Description

technical field [0001] The present invention relates to a method and a device for performing activation / deactivation of a secondary serving cell when a user equipment is connected to two different base stations supporting dual connectivity within a wireless communication system. Background technique [0002] In a wireless communication system, a user equipment (UE) can perform wireless communication through two or more base stations in a plurality of base stations (each base station configures at least one serving cell). This feature may be referred to as dual connectivity. In other words, the dual connectivity may be an operation in which a UE configured to be in a radio resource control (RRC) connected state connected to at least two different network points uses radio resources provided by the at least two different network points. Here, the at least two network points may be a plurality of base stations that are physically or logically different from each other, and one...
