A radio frequency radio (RF) transceiver that defines scheduling logic for generating transmission schedules for orthogonal frequency-division multiple access (OFDMA) RF transmissions from the RF transceiver, wherein the scheduling logic specifies at least one of a modulation type, a code rate, a sub-channel, and a sub-carrier for a plurality of symbols to be transmitted in a communication signal sub-frame. A processor generates outgoing data bits and outgoing test data bits for transmission from the RF transceiver as OFDMA transmission signals and OFDMA test data transmission signals, respectively, according to the transmission schedules to create loading within at least a portion of a cellular service area that corresponds with a test-loading value. The amount of the additional required loading is the difference between the test-loading value and an actual loading value.
