RADIO TRANSMISSION DEVICE AND RADIO TRANSMISSION METHOD Russian patent published in 2011 - IPC H04L27/00 H04B7/26 

FIELD: information technology.

SUBSTANCE: communication device increases throughput of a communication system by reducing the difference of transmission power between a scheduled control channel (SCCH) and a scheduled data channel (SDCH) so as to satisfy the required quality of peak-to-average power ratio (PAPR). In this device, an MCS selection unit (111) of a transmission unit (110) decides, with reference to a CQI lookup table, an MCS pattern (MCS 1) of the SDCH, an MCS pattern (MCS 2) of the SCCH and information (multiplex information) on multiplex positions on the time axes of those two channels, on the basis of the CQI information. On the basis of the MCS 2 and the MCS 1, encoding modulation units (112 and 113) perform encoding and modulating operations. According to the multiplex information, a channel multiplexing unit (114) time-division multiplexes the SCCH and SDCH so as to generate a transmission signal.

EFFECT: fewer level fluctuation errors due to fading and guaranteeing the required SCCH quality.
