摘要： A radio transmission device and a radio communication method employ sequence length decision units which hold a correspondence in which one basic sequence length is set for a plurality of transmission bandwidths. The sequence length decision units acquire transmission bandwidth information and decide a sequence length corresponding to the acquired transmission bandwidth information. A decision is made as to which of the cyclic extension process or the truncation process is to be executed on a Zadoff-Chu sequence according to the sizes of the acquired transmission bandwidth information and the basic sequence length. Then, a difference between the transmission bandwidth and the basic sequence length, i.e., the number of possible cyclic extension/truncation symbols, is obtained.

摘要： It is possible to provide a radio communication terminal device and a radio transmission method which can improve reception performance of a CQI and a reference signal. A phase table storage unit (112) stores a phase table which correlates the amount of cyclic shift to complex coefficients {w1, W2} to be multiplied on the reference signal. A complex coefficient multiplication unit (113) reads out a complex coefficient corresponding to the amount of cyclic shift indicated by resource allocation information, from the phase table storage unit (112) and multiplies the read-out complex coefficient on the reference signal so as to change the phase relationship between the reference signals in a slot.

摘要： It is possible to provide a radio transmission device and a radio communication method which can reduce inter-sequence interference and reduce the circuit size and the calculation amount even when RS is transmitted with different transmission bandwidths. Sequence length decision units (105) and (164) hold a correspondence in which one basic sequence length is set for a plurality of transmission bandwidths. The sequence length decision units (105) and (164) acquire transmission bandwidth information and decide a sequence length corresponding to the acquired transmission bandwidth information. Here, it is decided which of the cyclic extension process or the transaction process is to be executed on a ZC sequence according to the sizes of the acquired transmission bandwidth information and the basic sequence length. Then, a difference between the transmission bandwidth and the basic sequence length, i.e., the number of possible cyclic extension/truncation symbols is obtained.

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.

摘要： Disclosed are a radio communication terminal device, a radio communication base station device, and a radio communication method which can prevent input of an interference wave peak into a detection window of a cyclic shift sequence allocated to a local cell and improve the channel estimation accuracy in a base station. A frequency serving as a reference is set for a transmission band width of all the cells and respective terminals in which frame synchronization is established. By using the frequency as a reference point, a phase rotation addition unit (110) of a reference signal generation unit (108) adds a phase rotation corresponding to a frequency difference δ; between the transmission band of the reference point and that of the reference signal to a ZC sequence as a reference signal in the frequency region. The ZC sequence to which the phase rotation is added is multiplexed with transmission data in a multiplexing unit (114) and a multiplexed signal is transmitted from a transmission RF unit (115).
