Method and apparatus for assigning data to split bearers in dual connectivity
First Claim
1. A method of a first base station, the method comprising:
- receiving, via an X2 interface between the first base station and a second base station from the second based station, first information on a buffer for an evolved universal terrestrial radio access network (E-UTRAN) radio access bearer (E-RAB), second information on a buffer for a terminal which is associated with the first base station and the second base station, and third information on packets lost in X2 transmission between the first base station and the second base station; and
adjusting an amount of data to be assigned to the second base station based on the first information, the second information and the third information.

Abstract
A method and an apparatus for adjusting an amount of data to be assigned to a secondary base station in dual connectivity are provided. The method includes receiving, via an X2 interface between the first base station and a second base station from the second based station, first information on a buffer for an evolved universal terrestrial radio access network (E-UTRAN) radio access bearer (E-RAB), second information on a buffer for a terminal which is associated with the first base station and the second base station, and third information on packets lost in X2 transmission between the first base station and the second base station, and adjusting an amount of data to be assigned to the second base station based on the first information, the second information and the third information.

11. A first base station in a wireless communication system, the first base station comprising:
-
a transceiver configured to transmit and receive signals to and from a second base station and a terminal which is associated with the first base station and the second base station; and a processor configured to; control the transceiver to receive, via an X2 interface between the first base station and the second base station from the second based station, first information on a buffer for an evolved universal terrestrial radio access network (E-UTRAN) radio access bearer (E-RAB), second information on a buffer for a terminal which is associated with the first base station and the second base station, and third information on packets lost in X2 transmission between the first base station and the second base station, and adjust an amount of data to be assigned to the second base station based on the first information, the second information and the third information. - View Dependent Claims (12, 13, 14, 15, 16)
