    Abstract: Techniques to reduce transmit power required for transmission of messages from an access terminal to reduce interference to transmissions from other access terminals. In one aspect, messages to be transmitted are defined and/or coded such that they may be detected at different received signal qualities. The codewords may be defined having different distances to their nearest codewords. In another aspect, messages to be transmitted are assigned to different points in a signal constellation, with the points being located such that they may be received at different signal qualities. Codewords that may be received at a lower signal quality may be assigned to messages more likely to be transmitted at higher transmit power levels (e.g., when the access terminal is located further away) or to more frequently transmitted messages.

    Abstract: A system and method for adjusting quality of service in a communication system improves an allocation of resources in a communications environment with shared resources among multiple communicating stations by adjusting quality of service levels based on characteristics of the communicating stations. In a disclosed embodiment, a base station (130) communicates with one or more remote stations (110a, 110b). Quality of service levels for communications between the base station and a remote station 110 are adjusted based on a characteristic of the remote station. In this way, a lower quality remote station can be allocated a lower quality of service level than that allocated to a higher quality remote station, thereby preventing an inefficient allocation of shared resources and improving overall system performance.
