Method for operating serving cell in wireless communication system to which carrier aggregation scheme is applied and device for same

摘要

A method for operating a serving cell by a user equipment (UE) in a wireless communication system is disclosed. Specifically, the method comprises the steps of: forming a plurality of secondary cells (SCells), as one group, corresponding to a same frequency band through an upper layer; setting an enabled first SCell among the plurality of SCells as the serving cell and transmitting and receiving signals with a network; receiving a serving cell configuration message from the network to disable the first Scell and enable a second SCell; and setting the enabled second SCell as the serving cell and transmitting and receiving signals with the network.

1. A method for operating a serving cell at a user equipment (UE) in a wireless communication system, the method comprising:
receiving group information indicating at least one secondary cell (SCell) group via a higher layer signaling, wherein each of the at least one SCell group includes a plurality of SCells corresponding to a same frequency band; configuring an activated first SCell of a first SCell group among the at least one SCell group as the serving cell of the UE; receiving a serving cell configuration message from a network to deactivate the first SCell and activate a second SCell of the first SCell group, wherein the serving cell configuration message is included in a medium access control (MAC) control element (CE); and configuring the activated second SCell as the serving cell of the UE, wherein two or more SCells in a same SCell group of the at east one SCell group are not allowed to be activated simultaneously.
