Transmission control method, base station, mobile unit and communication system with delay diversity

摘要

A transmission control method for transmitting data through a series of antennas (24 to 26) using zones (K1 to K24) defined by frequency and time axes, comprising: providing the data to transmit a different delay from each other , according to the cyclic delay for each of the antenna outputs; and further characterized by providing the data to be transmitted from one of a series of initial phases (p1, p2) for each of the zones, said one of the initial phases being switched in the frequency domain and / or in the domain of time, such that said one (p1) of the initial phases for each of the zones (K1, K9, K17) is different from the other (p2) of the initial phases for at least one of the neighboring areas (K5, K13, K21), the neighboring areas being adjacent to each of the zones.
