Abstract  Abstract

A transmission control method in a base station for transmitting data through a plurality of antennas using regions defined by frequency and time axes. The data to be transmitted is provided with a delay different from each other according to cyclic delay for each of outputs of the antennas. The data to be transmitted is also provided with one of a plurality of initial phases for each of the regions the one of the initial phases being switched in frequency domain and/or time domain wherein the one of the initial phases for the each of the regions is different from other of the initial phases for at least one of neighboring regions the neighboring regions being adjacent to the each of the regions. The transmit section is adapted to give as said delay a phase rotation of 2?fm • nT (T stands for a prefixed time) to said signal to be transmitted through the n-th one of said antennas by a subcarrier of a frequency differing from the 0-th subcarrier by fm.
