FIELD: radio engineering, communication.
SUBSTANCE: invention relates to communication engineering and can be used in wireless communication systems. Disclosed is a terminal and a communication method whereby, even in a case of employing an asymmetric carrier aggregation system and further employing a MIMO transmission method for uplink channels, degradation of the error characteristic of control information can be prevented. In the terminal (200), a transport signal forming unit (212) generates transport signals by arranging, based on an arrangement rule, ACK/NACK and CQI in a plurality of layers. According to the arrangement rule, an error detection result is arranged, on a priority basis, in a layer different from the layer in which the channel quality information is arranged.
EFFECT: minimising puncturing of CQI using ACK/NACK, which prevents degradation of the error characteristic of control information.
