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： 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).

摘要： Provided is a cyclic shift sequence generation method which can prevent coming of an interference wave into a desired wave detection window even if a cyclic shift sequence has a high mutual correlation in different bandwidths, thereby improving a channel estimation accuracy in a base station. In this method, a cyclic shift sequence number to be allocated to a cell is decided in advance. Moreover, when the cyclic shift amount between cyclic shift sequences allocated in cells is Δ1 and the cyclic shift amount of the cyclic shift sequences allocated between the cells is Δ2, Δ1 and Δ2 are made different when generating a cyclic shift sequence.
