    • The embodiments disclose a method in a base station for extracting a resource block at a frequency band from a signal received from a terminal device in a radio communication system employing OFDM. The method comprising: removing a CP portion corresponding to the resource block from the signal; for each of a predetermined number of successive symbols in the signal after the CP portion corresponding to the resource block has been removed, performing a FFT of the symbol, extracting a frequency domain signal corresponding to the frequency band from the FFT of the symbol, performing an IFFT on the extracted frequency domain signal to yield a time domain signal, and storing the time domain signal to form a time sequence by concatenation; performing a FFT of the stored time sequence; and extracting subcarriers corresponding to the resource block from the FFT of the stored time sequence.
    • 实施方式公开了一种基站中的方法,用于从采用OFDM的无线通信系统中从终端装置接收的信号中提取频带的资源块。 该方法包括:从信号中去除对应于资源块的CP部分; 对于与资源块对应的CP部分之后的信号中的预定数量的连续符号中的每一个已经被去除,执行符号的FFT,从符号的FFT中提取与频带相对应的频域信号,执行 对所提取的频域信号进行IFFT以产生时域信号,并且通过级联来存储时域信号以形成时间序列; 执行所存储的时间序列的FFT; 以及从所存储的时间序列的FFT中提取与资源块相对应的子载波。
