COMMUNICATION SYSTEM, COMMUNICATION METHOD, BASE STATION DEVICE, AND MOBILE STATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/154083
Kind Code:
A1
Abstract:
In the present invention, a weighting factor control unit (105) notifies an upper layer (101) of a transmission weighting factor (Vj) of a slave base station device and a reception weighting factor (Uk) of a mobile station device connected to the slave base station device. Also, the weighting factor control unit (105) outputs a transmission weighting factor (V1) multiplied with a transmission signal of a master base station device (100-1) to a precoding unit (104) and a reference signal generation unit (106). Also, the weighting factor control unit (105) outputs a reception weighting factor (U1) of a mobile station device connected to the master base station device (100-1) to a control signal generation unit (107). The precoding unit (104) multiplies the transmission weighting factor (V1) to a modulation symbol output by a modulation unit (103). A connection destination selection unit (113) selects a handover destination for the mobile station device of a base station device and mobile station device that cooperate with each other to suppress interference using the reception weighting factor and/or the transmission weighting factor output by the weighting factor control unit (105).
