摘要： The circuit scale of a wireless communication apparatus at the data receiving end in a wireless communication performing an adaptive control for each of subcarriers or subchannels can be reduced. In the present apparatus, frame forming parts (103-1 to 103-m) each multiplex a pilot, control information and transport data to form a frame for a respective one of subchannels (1 to m). A subcarrier assigning part (104) assigns subcarriers designated from an adaptive control part (114) to the respective frames formed by the frame forming parts (103-1 to 103-m). A timing control part (105) establishes mutually different frame timing offsets to the respective frames received from the subcarrier assigning part (104).

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： Provided is a radio communication mobile station device which can accurately judge a CDD mode of an interference signal from other cell when using a CDD. In this device, a mode judging unit (110) specifies some data signals among data signals inputted from a demodulation unit (106) to be CDD channel estimation signals and measures SINR for each of the CDD channel estimation signals. The mode judging unit (110) judges a CDD mode of the interference signal from other cell according to a difference between average SINR of each pair of the CDD channel estimation signals formed by two CDD channel estimation signals. Moreover, when the mode judging unit (110) has judged that the CDD mode is SD-CDD, the mode judging unit (110) generates CQI corresponding to average SINR of all the CDD channel estimation signals.
