Abstract
Methods and systems are provided for transmission power control in a multiple access communication system, providing power ramping of a noise floor power level in advance of a high data rate transmission, at a comparatively higher power level, by a mobile station. The preferred method includes receiving a request at a base transceiver station (BTS) for a data transmission by a first mobile station of a plurality of mobile stations (), the data transmission to have a predetermined data transmission power level; measuring a noise floor power level (); and comparing the measured noise floor power level to the predetermined data transmission power level (). When the measured noise floor power level is less than the predetermined data transmission power level, the BTS schedules the data transmission from the first mobile station to occur following the power ramping of the noise floor, and directs the plurality of mobile stations to incrementally increase their transmit power levels to ramp the noise floor power level. Other methodologies to ramp the noise floor power level include injecting analog or simulated noise into the receive path of BTS, or directing the mobile station to transmit meaningless data at increasing power levels prior to transmission of requested data.
