Abstract

The instant invention provides a method and apparatus for efficiently selecting an optimal channel coding scheme from a plurality of successively higher order channel coding schemens (500) that are utilized over a packetized radio link in a wireless communication system. In a wireless system that utilizes packet switching, a more efficient and robust link can be maintained by dynamically selecting an optimal channel coding scheme best suited for the instantaneous conditions that exist on the radio link. The minimum data rate (500b-1) corresponding to a specified maximum data rate (500a-1) for a given channel coding scheme is determined. A normalized minimum throughput (500c-1) and its corresponding normalized maximum throughput (500d-1) for each channel coding scheme are determined based on the maximum data rate for the specified coding scheme. The optimal channel coding then determined based on whether an instantaneous measured throughput falls within the range of permitted throughput specified by the normalized minimum and maximum throughout for the current channel coding scheme used on the channel.
