摘要: A base station is used in a mobile communication system which uses the orthogonal frequency division multiplex (OFDM) method for downlink. The includes: means preparing control signal; reference multiplexing signal and to generate transmission symbol; performing inverse Fourier transform on symbol radio transmission. multiplied by first sequence formed random code second belonging certain group. Among plurality of sectors same cell, sequences different from one another are used. Between two or more cells, used, respectively.
