Abstract

Method and system for handling of special SCell selection in dual connectivity. The present invention relates to the field of wireless communication networks and more particularly to a User Equipment (UE) operating in dual connectivity mode in wireless communication networks. The principal object of the embodiments herein is to provide a method and system for handling of special SCell (PSCell) change by extending Event A3 or Event A5 to PSCell for relative comparison. Another object of the invention is to provide a method and system for handling of special SCell (PSCell) change with a new Event Ax.

Claims

1. A method for communication by a second base station in a wireless communication system including a first base station and the second base station, the method comprising:

receiving, from the first base station, a request message including a measurement result for one or more cells;

determining a primary second cell (PScell) among the one or more cells based on the measurement result; and

transmitting, to the first base station, a response message including configuration information of the PScell in response to the request message.
