In a radio communication apparatus for transmitting data using multiple code words, as response time taken by a transmitting station to receive a response signal (Ack/Nack signal) after the data is transmitted from the transmitting station (BS) to a receiving station (UE), a cycle of second response time (RTT2) corresponding to a low-order code word is longer than a cycle of first response time (RTT1) corresponding to a high-order code word. In the receiving station, received data of the low-order code word is decoded using at least one of retransmission data and the first received data of the high-order code word and response signals are respectively generated according to a decoding result of each of the code words and notification of the response signal is provided.

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.

摘要： It is possible to prevent lowering of a throughput of a radio communication system even when propagation path environments of an uplink line and downlink line are asymmetric. A maximum proper value calculation unit (115) calculates a maximum proper value from a channel matrix. A maximum proper value comparison unit (116) compares the maximum proper value with a maximum proper value of the downlink line reported separately from a base station. According to the comparison result obtained by the maximum proper value comparison unit (116), a proper mode initiative instruction unit (117) decides to pass the proper mode initiative to a communication partner or to the local device. When the initiative is to be passed to the local device, this fact is reported to a proper bam correction unit (118). When the proper beam correction unit (118) gets the proper mode initiative, the proper beam correction unit (118) corrects the correlation matrix by using the proper values of both of the downlink line and the uplink line and instructs a directivity forming unit (103) to form a proper beam according to the correlation matrix after the correction.

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： Disclosed are a wireless communication base station device and a division number determination method that improves the frequency diversity effect while maintaining channel estimation accuracy regardless of the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. A determination unit (117) determines the number of divisions in the frequency domain of a transmission signal from a wireless communication terminal device. Here, the determination unit (117) increases the number of divisions in the frequency domain of the transmission signal from the wireless communication terminal device as the number of pilot blocks included in the transmission signal increases. In addition, a scheduling unit (118) schedules allocation to the frequency resources of the divided transmission signal according to the number of divisions determined by the determination unit (117).

摘要： Reliability of beam selection by pre-coding is improved. A user terminal 52 selects an optimum beam (beam number ‘b’) in the next frame (t+1) based on the channel estimation value of a received pilot signal and transmits a difference value D (=b−a) between a beam number ‘a’ at the current transmission notified by a radio base station 51 and the selected beam number ‘b’ selected to be transmitted at the next transmission to the radio base station 51 as a feedback signal. The radio base station 51 previously stores the beam number ‘a’ notified at the previous transmission and combines the beam number based on the difference value D received as the received feedback signal and the previously notified beam number ‘a’ to restore the beam number ‘b’ desired by the user terminal 52. Pre-coding processing adapted to the beam number ‘b’ is performed and transmission to the user terminal 52 is executed in a state in which a beam of the appropriate beam number ‘b’ is formed.
