Abstract
A method and apparatus for determining the data rate of a reverse link communication. An embodiment includes transmitting at a null rate on the communication channel only when the station is not transmitting voice, signaling, or data. An embodiment includes determining a maximum requested rate based on the normalized average pilot transmit power and the pilot reference value, and determining the timing of the rate request. An embodiment involves determining a maximum transmission rate. An embodiment involves determining sufficient power and a power-control set point.
Claims12
A method of determining a maximum rate, comprising:
- determining a normalized average pilot transmit power;
- determining a transmit power for a mobile station based on the normalized average pilot transmit power, a pilot reference value, and a ratio of traffic power to pilot power for a rate;
- determining a ratio of a maximum transmit power of the mobile station to a headroom for channel variation;
- and
- determining a maximum value for the rate for which the transmit power of the mobile station is less than or equal to the ratio of the maximum transmit power of the mobile station to the headroom for channel variation.
A mobile station, comprising:
- an antenna for receiving and transmitting a plurality of signals;
- a receiver coupled to the antenna, the receiver receives the plurality of receive signals;
- a controller coupled to the receiver, wherein the controller is configured to
- determine a normalized average pilot transmit power from the plurality of receive signals,
- determine a transmit power for the mobile station based on the normalized average pilot transmit power, a pilot reference value, and a ratio of traffic power to pilot power for a rate,
- determine a ratio of a maximum transmit power of the mobile station to a headroom for channel variation, and
- determine a maximum value of the rate for which the transmit power of the mobile station is less than or equal to the ratio of the maximum transmit power of the mobile station to the headroom for channel variation;
- and
- a transmitter coupled to the controller, the transmitter conditions the maximum rate for transmission.
A non-transitory computer-readable medium embodying a program of instructions executable by a processor to perform a method of determining a maximum rate, the method comprising:
- determining a normalized average pilot transmit power;
- determining a transmit power for a mobile station based on the normalized average pilot transmit power, a pilot reference value, and a ratio of traffic power to pilot power for a rate;
- determining a ratio of a maximum transmit power of the mobile station to a headroom for channel variation;
- and
- determining a maximum value for the rate for which the transmit power of the mobile station is less than or equal to the ratio of the maximum transmit power of the mobile station to the headroom for channel variation.
