ABSTRACT:
A communication channel is dynamically assigned to a mobile station in autonomous decentralized channel assignment in TDMA/TDD communications system. An interference detection criterion is determined depending on a signal strength of a call request signal. It is determined whether interference occurs in a transmitting time slot relative to the interference detection criterion in a selected channel, and further determined whether interference occurs in a receiving time slot relative to a predetermined interference detection criterion in the selected channel. When it is determined that no interference occurs in the selected transmitting and receiving time slots, the selected channel is assigned to the mobile station.
