Abstract

An apparatus, system, and method efficiently manage reverse link resources by allowing a mobile station to select between transmitting a payload at a standard power level and transmitting a smaller payload at a boosted power level. The mobile station, therefore, can autonomously select a QoS (Quality of Service) level for physical layer packets. Based on reverse link transmission information received from a base station, the mobile station derives a reverse link transmission guideline defining the power levels and associated payloads for at least a standard service and boosted service. The mobile station selects a reverse link transmission power level from a plurality of power levels including at least a standard reverse link transmission power level associated with a standard payload size and a boosted reverse link transmission power level associated with a boosted payload size where the standard payload size is greater than the boosted payload size.

Claims

1. A method for managing resources of a communication link from a mobile station to a base station in a communication system, the method comprising:

selecting a payload size of a data packet for transmission over said communication link;

receiving a boost transmission power value from a base station indicating an amount of power level difference between a boosted power level and a standard power level for transmission of said data packet over said communication link;

selecting either said boosted power level or said standard power level based on a latency requirement of transmitting said data packet;

transmitting said data packet at said payload size and at said selected power level from said mobile station to said base station over said communication link.

2. The method as recited in claim 1 further comprising:

relating said selected power level to a traffic to pilot power ratio, thereby said boosted power level being a boosted traffic to pilot power ratio and said standard power level being a standard traffic to pilot power ratio.

3. The method as recited in claim 1 wherein said latency requirement of transmitting said data packet is in accordance with a hybrid automatic response protocol.

4. The method as recited in claim 1 further comprising:

transmitting said boost transmission power value from said base station.

5. The method as recited in claim 1 further comprising:

receiving said transmitted said data packet at said payload size and at said selected power level from said mobile station at said base station over said communication link.

6. An apparatus for managing resources of a communication link from a mobile station to a base station in a communication system, the apparatus comprising:

a controller for selecting a payload size of a data packet for transmission over said communication link;

a transceiver for receiving a boost transmission power value from a base station indicating an amount of power level difference between a boosted power level and a standard power level for transmission of said data packet over said communication link;

said controller further for selecting either said boosted power level or said standard power level based on a latency requirement of transmitting said data packet;

said transceiver further for transmitting said data packet at said payload size and at said selected power level from said mobile station to said base station over said communication link.

7. The apparatus as recited in claim 6, wherein said controller further for relating said selected power level to a traffic to pilot power ratio, thereby said boosted power level being a boosted traffic to pilot power ratio and said standard power level being a standard traffic to pilot power ratio.

8. The apparatus as recited in claim 6, wherein said controller further for said latency requirement of transmitting said data packet to be in accordance with a hybrid automatic response protocol.

9. The apparatus as recited in claim 6 further comprising:

a controller and a transceiver in said base station configured for transmitting said boost transmission power value, and for receiving said transmitted said data packet at said payload size and at said selected power level from said mobile station over said communication link.
