Abstract:
1. A mobile terminal apparatus transmitting ACK/NACK control information and reference signals using a physical uplink control channel format comprised of a plurality of time blocks, the mobile terminal apparatus comprising: a cyclic shift section configured to add cyclic shifts to a plurality of reference signal blocks out of the plurality of time blocks; and a block spreading section configured to multiply the plurality of reference signal blocks by a first orthogonal code in a first group of orthogonal codes and to multiply a plurality of ACK/NACK control information blocks out of the plurality of time blocks by a second orthogonal code in a second group of orthogonal codes, wherein the cyclic shift section determines the cyclic shifts, which are added to the plurality of reference signal blocks, based on the second orthogonal code in the second group of orthogonal codes by which the plurality of ACK/NACK control information blocks are multiplied.
