ABSTRACT:
An adaptive method for channel assignment in a cellular multiple access wireless communication system that has a cell station (CS) and a number of subscriber stations augments existing channel assignment protocol and thus is downward compatible with existing time division multiple access (TDMA), frequency division multiple access (FDMA), code division multiple access (CDMA), and spatial division multiple access (SDMA) system protocols. The method adaptively determines the power required for establishing an acceptable quality connection between a subscriber station and the cell station and provides an early warning trial signal for advising existing connections that a new connection is about to be established. The early warning, followed by a pause, provides a basis and a time interval for taking corrective interference action if the trial signal indicates that an unacceptable level of interference will result if the trial connection is established. The early warning signal and associated pause are useful for intracellular and intercellular interference management.
