FIELD: information technologies. ^ SUBSTANCE: communication device is proposed, which ensures enhancement of throughput capacity of a communication system by reduction of difference in transfer capacity between a scheduled control channel (SCCH) and a scheduled data channel (SDCH), so that by virtue of this the required quality of peak to average power ratio (PAPR) is met. In this device a unit (111) to select a transfer MCS unit (PO) makes a choice, referring to a reference table CQI, of a template (MCS 1) MCS at SDCH, a template (MCS 2) MCS at SCCH and information (information of multiplexing) on multiplexing positions on a time axis of such two channels based on CQI information. On the basis of MCS 2 and MCS 1, units (112 and 113) of coding and modulation perform operations of coding and modulation. According to information of multiplexing, a unit (114) of channel multiplexing multiplexes SCCH and SDCH with time division in order to thus generate a transfer signal. ^ EFFECT: reduction of level fluctuation errors specified by fading and guaranteeing the required quality of SCCH. ^ 4 cl, 15 dwg |
