Abstract
In a microcellular cordless telephone network, radio speech channels are divided into several channel groups such that no intermodulation products occur among the channels of each group. In each microcell is located a base unit to which one of the channel groups is dynamically assigned. To achieve the channel assignment, each base unit generates priority values of the channel groups as representations of usage of the channel groups, consistently updates them through a statistical process and assigns one of the channel groups having a maximum priority value to the base unit.
