What is claimed is: 1. A method for indicating quality of a radio frame transmitted over a wireless link, comprising: receiving a radio frame from a wireless link; determining for the radio frame a plurality of link parameters comprising a power indicator, the power indicator based on a power control trend of the wireless link; generating a quality indicator for the radio frame based upon the plurality of link parameters comprising the power indicator, wherein the link parameters are weighed unequally in generating the quality indicator; and sending the quality indicator to a frame selector operable to select the radio frame in accordance with the quality indicator. 2. The method of claim 1, wherein the power control trend comprises a slope of power control commands for the link. 3. The method of claim 1, wherein the power control trend comprises a slope of power control commands for the link and at least one other link participating in a soft handoff with the link. 4. A method for indicating quality of a radio frame transmitted over a wireless link, comprising: receiving a radio frame from a wireless link; determining for the radio frame a plurality of link parameters comprising a bit energy indicator, the bit energy indicator based on a bit energy to interference ratio; generating a quality indicator for the radio frame based upon the plurality of link parameters comprising the bit energy indicator, wherein the link parameters are weighed unequally in generating the quality indicator; and sending the quality indicator to a frame selector operable to select the radio frame in accordance with the quality indicator. 5. A method for indicating quality of a radio frame transmitted over a wireless link, comprising: receiving a radio frame from a wireless link; determining a quality indicator for the frame based upon a plurality of link parameters, wherein the link parameters are weighed unequally in determining the quality indicator; and sending the quality indicator to a frame selector operable to select the radio frame in accordance with the quality indicator. 6. The method of claim 5, wherein the link parameters comprise: a bit energy indicator, the bit energy indicator based on a bit energy to interference ratio; and a power indicator, the power indicator based on a power control trend of the wireless link. 7. A system for indicating quality of a radio frame transmitted over a wireless link, comprising: means for receiving a radio frame from a wireless link; means for determining for the radio frame a plurality of link parameters comprising a power indicator, the power indicator based on a power control trend of the wireless link; means for generating a quality indicator for the radio frame based upon the plurality of link parameters comprising the power indicator, wherein the link parameters are weighed unequally in generating the quality indicator; and means for sending the quality indicator to a frame selector operable to select the radio frame in accordance with the quality indicator. 8. The system of claim 7, wherein the power control trend comprises a slope of power control commands for the link. 9. The system of claim 7, wherein the power control trend comprises a slope of power control commands for the link and at least one other link participating in a soft handoff with the link. 10. A system for indicating quality of a radio frame transmitted over a wireless link, comprising: means for receiving a radio frame from a wireless link; means for determining for the radio frame a plurality of link parameters comprising a bit energy indicator, the bit energy indicator based on a bit energy to interference ratio; means for generating a quality indicator for the radio frame based upon the plurality of link parameters comprising the bit energy indicator, wherein the link parameters are weighed unequally in generating the quality indicator; and means for sending the quality indicator to a frame selector operable to select the radio frame in accordance with the quality indicator. 11. A system for indicating quality of a radio frame transmitted over a wireless link, comprising: means for receiving a radio frame from a wireless link; means for determining a quality indicator for the frame based upon a plurality of link parameters, wherein the link parameters are weighed unequally in determining the quality indicator; and means for sending the quality indicator to a frame selector operable to select the radio frame in accordance with the quality indicator. 12. The system of claim 11, wherein the link parameters comprise: a bit energy indicator, the bit energy indicator based on a bit energy to interference ratio; and a power indicator, the power indicator based on a power control trend of the wireless link. 13. A method for soft handoff, comprising: receiving over a each of a plurality of soft handoff links a radio frame; for each radio frame determining a quality indicator, the quality indicator generated based upon a plurality of link parameters comprising at least: a bit energy indicator, the bit energy indicator based on a bit energy to interference ratio; a power indicator, the power indicator based on a power control trend of the wireless link, wherein the link parameters are weighed unequally in generating the quality indicator; forwarding the frame and quality indicator to a base station controller; and selecting one of the frames based on the quality indicator. 14. A method for soft handoff, comprising: at each of a plurality of transceivers in communication with one of a plurality of soft handoff links for a connection: receiving a redundant radio frame; temporarily holding the redundant radio frame; determining a quality indicator for the redundant radio frame; transmitting to a frame selector the quality indicator; selecting at the frame selector one of the redundant frames as a selected frame, such selection based upon the quality indicator received from each transceiver; requesting the selected frame from the transceiver holding the selected frame; and forwarding the selected frame for transmitting in the connection. 15. The method of claim 14, further comprising discarding the redundant radio frames that are not the selected frame. 16. A system for indicating quality of a radio frame transmitted over a wireless link comprising logic encoded in media, the logic operable to: receive a radio frame from a wireless link; determine for the radio frame a plurality of link parameters comprising a power indicator, the power indicator based on a power control trend of the wireless link; generate a quality indicator for the radio frame based upon the plurality of link parameters comprising the power indicator, wherein the link parameters are weighed unequally in generating the quality indicator; and send the quality indicator to a frame selector operable to select the radio frame in accordance with the quality indicator. 17. A system for indicating quality of a radio frame transmitted over a wireless link comprising logic encoded in media, the logic operable to: receiving a radio frame from a wireless link; determining a quality indicator for the frame based upon a plurality of link parameters, wherein the link parameters are weighed unequally in determining the quality indicator; and sending the quality indicator to a frame selector operable to select the radio frame in accordance with the quality indicator.
