摘要： In a radio communication system using OCC for DMRS, a base station apparatus correctly receives PUSCH. If a first mode is set in which a demodulation reference signal of a physical uplink shared channel is multiplied by an orthogonal code determined in advance or if a temporary C-RNTI was used for a transmission of downlink control information, the demodulation reference signal of the physical uplink shared channel is multiplied by the orthogonal code determined in advance, and if a second mode is set in which the demodulation reference signal of the physical uplink shared channel is multiplied by an orthogonal code determined on the basis of cyclic shift information in the downlink control information and moreover, if an RNTI other than the temporary C-RNTI was used for the transmission of the downlink control information, the demodulation reference signal of the physical uplink shared channel is multiplied by the orthogonal code determined on the basis of the cyclic shift information in the downlink control information.

摘要： Mobile station apparatuses are provided that receive downlink allocation information from a base station apparatus in a downlink control channel. Each mobile station apparatus performs demodulation, decoding, and cyclic redundancy check on the downlink shared channel in accordance with the downlink allocation information received. Each mobile station apparatus generates an acknowledgement or a non-acknowledgement in accordance with the result of the cyclic redundancy check. Each mobile station apparatus then selects the lowest number and the second lowest number of the numbers of the control channel elements in which the downlink allocation information is received. Based on the selected numbers, each mobile station apparatus 2 obtains a physical resource block (PRB), as well as a cyclic shift and an orthogonal code sequence in the time domain for each transmission antenna, and spreads the acknowledgement or the non-acknowledgement and the uplink pilot channel.
