Abstract
In each cell of a plurality of cells of a mobile communication network assigned with a predetermined number of radio channels, a base station allocates to a call one of the radio channels according to autonomous channel reuse partitioning as a communication channel on transmitting messages to and from a mobile unit which is currently present alive in the cell under consideration. For use as the communication channel, the radio channel should preferably have a base and a mobile carrier to interference ratio which is equal to or greater than a first allocation threshold level determined by a sum of a power control margin for base and mobile transmission powers and a second allocation threshold level determined to be sufficient for transmission of the messages. If such a radio channel is not available, another of the radio channels is used as the communication channel that has the base and the mobile carrier to interference ratios both equal to or greater than the second allocation threshold level. It is thereby rendered possible to control the mobile transmission power after allocation of the communication channel and furthermore the base transmission power.
