A method and system for the adaptive allocation of channels within a radio communication system, specifically a cellular network, is presented. The allocation method takes advantage of measurements made by the mobile radiotelephone and allocates channels based on the carrier to interference ratio. Using adaptive power control, consideration is given to maintaining an acceptable carrier to interference ratio while at the same time minimizing transmit power. Exemplary embodiments consider independent allocation of the uplink and downlink as well as independent determination of the uplink and downlink power levels. Other exemplary embodiments also give consideration to an efficient method for slot allocation in a TDMA communication system.
A method for assigning uplink radio channels in a radio communication system comprising the steps of: (a) measuring, in a mobile station, received signal strength indications (RSSIs) of control signals broadcast from at least one base station; (b) determining a path loss between the mobile station a
A method for assigning uplink radio channels in a radio communication system comprising the steps of: (a) measuring, in a mobile station, received signal strength indications (RSSIs) of control signals broadcast from at least one base station; (b) determining a path loss between the mobile station and the at least one base station using the RSSI measurements; (c) measuring, in the at least one base station, an RSSI of interference signals on a plurality of available traffic channels; (d) determining transmit powers required for the mobile station to produce a signal on each of the plurality of available traffic channels at the at least one base station, wherein a strength of said signal is a predetermined level above a corresponding RSSI interference level measured on a traffic channel taking into consideration the path loss; and (e) assigning one of said plurality of available traffic channels as an uplink channel based on said determined transmit powers.
