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.
