    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: A wireless communication terminal apparatus wherein the occurrences of inter-sequence interferences between a reference signal preceding a sequence hopping and a reference signal following the sequence hopping can be reduced so as to improve the randomizing effect achieved by the sequence hopping. In this apparatus, a sequence number deciding part (105) has a table in which the sequence lengths of Zadoff-Chu sequences used for reference signals are associated with the sequence numbers of Zadoff-Chu sequences used for reference signals of a slot #1 and with the sequence numbers of Zadoff-Chu sequences used for reference signals of a slot #2. In accordance with a sequence length according to a transmission bandwidth 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 hopping amounts are provided to a plurality of slot-#2-specific Zadoff-Chu sequences having 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.
