Autonomous channel assignment control for flexible reuse in mobile radio systems

Two control techniques are proposed for assigning radio channels in order to increase the spectrum efficiency. One is an autonomous channel assignment control for reusing radio channels at shorter distances according to the conditions of channels. The other is a control for assigning the channel of a neighboring cell when there is no available channel in the closest cell. It is shown that these techniques are significant in mobile radio systems using sector cells and TDMA channels, and the spectrum efficiency is clarified by comparison of system capacity.<
