Abstract  Abstract

PROBLEM TO BE SOLVED: To provide a transmission control method capable of obtaining frequency diversity effects or multiuser diversity effects without being affected by a state of a propagation path.

SOLUTION: The present invention relates to a transmission control method in a transmission system for performing slot assignment for each of chunks divided in a frequency direction and a time direction including: delaying output signals of a plurality of transmission antennas respectively when sending output signals to the plurality of transmission antennas; performing control in such a way that a maximum delay time between the plurality of transmission antennas is changed either to a predetermined first value smaller than 1/Fc or to a predetermined second value greater than 1/Fc when a frequency bandwidth of the chunks is defined as Fc; and selecting whether to apply control of the delay in accordance with a kind of a physical channel.
