    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.

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.

    摘要: Provided is a radio communication device which can reduce the affect of inter-cell interference using a small reception process amount. The radio communication device includes a sequence number setting unit (101) which sets a sequence number for a ZAC sequence used for spreading a response signal and another sequence number for a ZAC sequence used for a reference signal in a ZAC sequence generation unit (102) and a ZAC sequence generation unit (109), respectively. The ZAC sequence generation unit (102) generates a ZAC sequence of the set sequence number from the sequence number setting unit (101). A spread unit (104) spreads the response signal. The ZAC sequence generation unit (109) generates a set ZAC sequence from the sequence number setting unit (101) and outputs the ZAC sequence as a reference signal to an IF FT unit (110). A sequence number setting unit (101) changes the sequence number at a transmission switching timing between the response signal and the reference signal.
