Title:
TERMINAL DEVICE AND BASE STATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/181861
Kind Code:
A1
Abstract:
There has been a problem in that when the transmission modes of terminal devices that are multiplexed by a base station device by means of Superposition Coding (SC) are different, a data signal and reference signal are multiplexed, channel estimation accuracy deteriorates, and throughput is reduced. Provided is a base station device that transmits data to a plurality of terminal devices, said base station device having a signal multiplexing unit that multiplexes data signals of a first and second terminal device on the same resource, a transmission power control unit that configures the transmission power allocated to a data signal addressed to the second terminal device to be higher than the transmission power allocated to a data signal addressed to the first terminal device, and a control information generation unit that generates control information for reporting information relating to different downlink transmission modes to the first and second terminal devices which transmit data signals at different transmission powers. Control information including the transmission mode of the other terminal device is generated by the control information generation unit in the first and/or second terminal device.
