    摘要： In a multiuser MIMO system, entire system throughput achieved during retransmission is significantly enhanced. When an interference signal addressed to another user equipment (UE2) 200b has been demodulated successfully, a user equipment (UE1) 200a holds the demodulated data pertaining to the interference signal, and feeds back ACK information about the UE2 and CQI information achieved after elimination of the interference signal to a radio base station (BS) 100. When the UE2 performs retransmission after ended in a receiving failure and when the UE1 has demodulated the interference signal addressed to the UE2 successfully, the BS changes the distribution of communication resources in such a way that communication resources for the UE2 become larger than those for the UE1. At the time of retransmission, the UE1 eliminates the interference signal from a newly-received signal by use of previously-held demodulated data pertaining to the interference signal, and the UE2 combines data pertaining to the desired signal held during previous receiving failure with data pertaining to the retransmitted signal by means of soft combining.

    摘要： To improve throughput by reducing the resource used for transmitting a parameter relating to retransmission control and decreasing the overhead of retransmission control signaling. In a case where a retransmission control method is employed in consideration of adaptive MCS control in which the encoding rate can be changed, the scheduling section sets the MCS in accordance with CQI notified from the communication counterpart apparatus. When transmission data is encoded, the RV parameter bit-number setting section sets the number of bits used for signaling the RV parameter to decrease as the encoding rate of the first transmission is decreased and sets the RV parameter based on the number of bits. For example, in a case where the encoding rate R is R>2/3, two bits are set. In a case where the encoding rate 1/3

    摘要： The signaling amount in selecting a plurality of beams is reduced in pre-coding to thereby enhance the throughput. To select a plurality of beams when the pre-coding is applied, when notification of a beam number is provided in a feedback signal from a user equipment 102 as a reception station to a radio base station 101 as a transmission station, a superior beam number having a high quality rank with small time variation is bound up and fixed for a predetermined time period and notification of only a inferior beam number is provided within the time period. For example, to select three beams from six beams, first, notification of the superior two beam numbers (beam numbers ‘b’ and ‘c’) is provided and the superior beam numbers are fixed for a predetermined time period and then notification of only the inferior one beam number (beam number ‘e’) is provided within the predetermined time period for reducing the signaling amount for providing beam number notification.
