A communications platform ( 100 ) assigns communication channels ( 58, 78 ) to users based on a power level associated with the individual users. An available bandwidth for use by the communications platform ( 100 ) in segmented into a number of sub-bands using a bank of filters ( 54, 78 ). A number of independent communication channels ( 58, 78 ) are then provided within each of the sub-bands using an appropriate multiple access scheme (e.g., code division multiple access). A power range is then specified for each of the sub-bands. When a communication connection is to be established, a power level associated with the connection is determined. One or more sub-bands are then identified that have power ranges encompassing the determined power level. A channel is then assigned to the communication connection from one of the identified sub-bands.
