FIELD: radio engineering, communication.
SUBSTANCE: invention relates to a mobile communication system. A terminal (200), which uses a plurality of different layers to transmit two code words in which control information is placed, comprises: a resource amount determining unit (204) which determines, based on a lower one of the encoding rates of the two code words or based on the average value of the inverses of the encoding rates of the two code words, resource amounts of control information in the respective ones of the plurality of layers; and a transport signal generating unit (205) which places, in the two code words, the control information modulated using the resource amounts, thereby generating a transport signal.
EFFECT: invention enables a terminal device to prevent degradation of reception quality of control information even when employing SU-MIMO transmission system.
