METHOD AND APPARATUS FOR PERFORMING ACTIVATION/DEACTIVATION OF SERVING CELL IN WIRELESS COMMUNICATION SYSTEM SUPPORTING DUAL CONNECTIVITY

摘要

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.

主权项

1. A User Equipment (UE) supporting a dual connectivity, the UE communicating with a first node and a second node for the dual connectivity, the UE comprising:
a receiver to receive, from the first node, information including activation/deactivation indicators of secondary serving cells (SCells) in a first SCell group configured for the UE, and to receive, from the second node, information including activation/deactivation indicators of SCells in a second SCell group configured for the UE; and a processor operationally coupled to the receiver and configured to:
control activation/deactivation states of the SCells in the first SCell group according to the activation/deactivation indicators of the SCells in the first SCell group identified from the information received from the first node; andcontrol activation/deactivation states of the SCells in the second SCell group according to the activation/deactivation indicators of the SCells in the second SCell group identified from the information received from the second node.
