RADIO TRANSMISSION DEVICE AND RADIO TRANSMISSION METHOD Russian patent published in 2013 - IPC H04L27/00 

FIELD: radio engineering, communication.

SUBSTANCE: disclosed is a communication device which improves the throughput of a communication system by reducing the difference of transmission power between an SCCH and an SDCH so as to satisfy the required quality of a 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, based on the CQI information. Based on 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.
