A transmitter transmits the desired signal using a continuous duty cycle at transmission rates of less than full rate (FIG. 6 ). The energy used in each power control group is related to the transmission rate. By repeating the power control groups, time division diversity (FIG. 6 ) is provided. In the receiver, the received power control groups are analyzed and compared to several levels of energy thresholds (73, 75, 77, 79). The results of the comparisons are converted into a power control signal (74, 76, 78, 80, 81) and returned to the mobile. The mobiles are capable of selecting the appropriate bit (93) and adjusting their power (94). Alternatively, an indicator of the transmission rate can be forwarded (155) in advance of the frame. The receiver compares a power estimate with the threshold for the transmission rate indicated (166).

A method of controlling power in a CDMA communication system, said method comprising the step of: processing, at a first transmission rate, a first frame of a continuous signal to be transmitted from a mobile station to a base station; storing said first frame of said continuous signal in a mobile station; processing, at a second transmission rate, a second frame of a continuous signal to be transmitted from said mobile station to said base station; inserting, in said first frame of said continuous signal, an indicator of said second transmission rate of said second frame, to be used to control power in said CDMA communication system; and transmitting said first frame of said continuous signal.
