Abstract: Systems and techniques for changing between secondary cells in dual connectivity communication. A user device (110A) operating in dual connectivity with a master base station (102) and a source base station (106A) transmits a change request to a target secondary base station (106B), seeking a connection change to a target base station that is to be used as the secondary base station. The target base station (106B) notifies the master base station (102) of the change request, and the master base station performs changeover operations—for example, notifying the source base station (106A) that it is no longer to be used in dual connectivity with the user device (110A) making the request, and notifying the user device (110A) that the change request has been accepted, with the user device (110A) then proceeding to establish connection with the target secondary base station (106B).

Abstract: A base station determines first quality information indicative for a quality of a first part of subframes of a communication channel and a second quality information indicative for a quality of a second part of the subframes of the communication channel. Feedback information is received from a UE being indicative for the quality of the communication channel. A first compensation value is determined based on the first quality information and the feedback information, wherein the compensation value compensates a difference between the first quality information and the feedback information. A second compensation value is determined based on the second quality information and the feedback information, wherein the compensation value compensates a difference between the second quality information and the feedback information. The feedback information is adjusted based on the determined first and second compensation values. The communication channel is configured based on the adjusted feedback information.
