ABSTRACT:
In the method for dynamically determining interference and carrier-to-interference ratio, interference is measured during an active TDMA time slot. In one embodiment, a base station determines the interference level in an active time slot using power level measurement taken during a DTX OFF period, when a mobile station is transmitting in discontinuous transmission mode. In another embodiment, a base station orders a mobile station to cease transmission during a SACCH portion of the time slot, and determines an interference level I measurement using power level measurements taken during the inactive SACCH field. Another embodiment provides for the determination of an interference level I using power level measurements taken during the guard and ramp fields.
