    • The present invention relates to an apparatus and method for variable fast Fourier transform. According to an embodiment of the present invention, two n-point fast Fourier transform (FFT) processors are used to generate two n-point FFT output data or one 2n-point FFT output data. The one 2n-point input data is alternately input to the two n-point FFT processors. Each of the two n-point FFT processors selects a twiddle factor for the n-point input data or the 2n-point input data and performs fast Fourier transform. A butterfly operation is performed on signals obtained by performing fast Fourier transform on the 2n-point input data signal, and the processed signals are aligned in an output order. According to this structure, it is possible to realize a fast Fourier transform hardware engine that selectively performs multi-frequency allocation in a base station system that supports the multi-frequency allocation.

    • A communication method according to the present invention includes receiving MAP in formation, acquiring an initial scheduled frame number and a current frame number from the MAP information, calculating the difference between the initial scheduled frame number and the current frame number, comparing the difference between the initial scheduled frame number and the current frame number with a reference value and setting a scheduled frame number, and performing transmission or reception in the scheduled frame. Therefore, even though a MAP loss occurs, the mobile station can receive only downlink data effective in downlink, thereby reducing power consumption for unnecessary reception, and can exactly perform transmission in a frame in which it should transmit in uplink.
    • 根据本发明的通信方法包括:接收MAP,从MAP信息中获取初始调度帧号和当前帧号,计算初始调度帧号与当前帧号之间的差值, 初始调度帧号和具有参考值的当前帧号,并设置调度帧号,并在调度帧中执行发送或接收。 因此,即使发生MAP丢失,移动台也可以只接收下行链路中有效的下行链路数据,从而减少不必要的接收的功耗,能够在上行链路中发送的帧中正确地进行发送。
