摘要
The invention relates to a method of increasing interference diversity in an FDMA/TDMA-based cellular system, in which system a transmission channel of the system between a mobile station (12) and a base station (11) is realized as a burst in a time slot of a TDMA frame (30) of a carrier of the base station. According to the invention, frequency hopping is used in a first part of the base stations (11) of the system, and interference diversity is increased further in such a way that additionally, in a second part of the base stations (11) of the system, at least one transmission channel uses at least two different time slots of a TDMA frame in sequential TDMA frames (30) in accordance with a predetermined repeated sequence, and that the sequences used by the separate base stations (11) are mutually coordinated in such a manner that at least the sequences used by the cells situated within the range of influence of each other are mutually sufficiently uncorrelated. The invention relates further to a cellular system according to the method.
