Abstract

A method and apparatus for transmitting digital data in a cellular environment. Adjacent cells of the cellular system (1 and 2A-2F) are prevented from simultaneously transmitting data. Because the noise from transmission of adjacent cells is a primary source of interference, the transmission rate of power limited base stations (1-3) can be dramatically increased when the noise from adjacent cells is eliminated. The transmissions to each subscriber station (6) are made at a fixed transmission power level. However, the data rate of transmitted signals differs from one subscriber station (6) to another depending the path loss differences. In a first exemplary embodiment, the data rate of transmissions to a subscriber station (6) is determined by selecting an encoding rate for the transmitted signal while holding the symbol rate constant. In a second exemplary embodiment, the data rate of transmission to a subscriber station (6) is determined by selecting a modulation format for the transmitted signal which directly changes the symbol rate of transmission to a subscriber station (6).
