    摘要: Provided is a radio communication base station device capable of obtaining a large multi-user diversity effect while suppressing increase of overhead of a communication signal. The radio communication base station device includes a scheduler (101) which performs scheduling for allocating RB (Resource Block) to terminals belonging to a first group by FSA (Frequency Scheduled Allocation) in accordance with line quality of each terminal and each RB and allocating remaining RB other than the RB allocated to the terminals belonging to the first group, to terminals belonging to a second group according to a predetermined allocation rule. That is, the scheduler (101) performs RB allocation to the terminals belonging to the first group with a higher priority than RB allocation to the terminals belonging to the second group. Each time the scheduler (101) performs FSA, it outputs the result of the FSA to the terminals belonging to the first group to an encoding unit (102) and an extraction unit (111) and does not output any scheduling result to the terminals belonging to the second group.

    摘要: A wireless communication terminal apparatus wherein the occurrences of inter-sequence interferences between cells can be reduced. In this apparatus, a sequence number deciding part (105) has a table in which the sequence numbers of a plurality of Zadoff-Chu sequences having different sequence lengths are associated with the sequence group numbers of a plurality of sequence groups into which the Zadoff-Chu sequences are grouped and with the transmission bandwidths of reference signals. In accordance with a sequence group number and a transmission bandwidth both received from a decoding part (104), the sequence number deciding part (105) refers to the table to decide the sequence number of a Zadoff-Chu sequence. In the table of the sequence number deciding part (105), different sequence-number start-positions are established for the Zadoff-Chu sequences having the different sequence lengths.

    摘要: Disclosed are a radio transmission device and a radio transmission method which can reduce a processing amount or a memory amount while maintaining the randomizing effect of other cell interference. When using as a reference signal, a ZC sequence of the sequence length uniquely correlated to a transmission bandwidth of a reference signal, as the transmission bandwidth becomes smaller and the sequence length of the ZC sequence becomes shorter, the sequence is switched at a shorter time interval and as the transmission bandwidth becomes greater and the sequence length of the ZC sequence becomes longer, the switching is performed at a longer time interval. Thus, a reference signal is generated by using the ZC sequence in accordance with the timing into which the reference signal transmission bandwidth and the sequence are switched.
