FIELD: radio engineering.
SUBSTANCE: there proposed is radio communication device having the possibility of adaptive control of modulation and speed method of coding (MCS) of data channel in compliance with the obtained channel quality information (CQI). Device includes control unit having the possibility of selecting modulation and speed method of coding of data channel in compliance with the obtained channel quality information on the basis of the first ratio of compliance between modulation and speed method of channel coding of data and information on channel quality, and besides, having the possibility of selecting transmission power of control channel in compliance with the obtained information on channel quality on the basis of the second ratio of compliance between transmission power of control channel and information on channel quality; and transmitting unit having the possibility of transmitting the data channel in compliance with the chosen modulation and speed method of coding, and with possibility of transmitting the control channel with the selected power.
EFFECT: reducing the volume of information of control channel and performing the appropriate control of control channel transmission power.
