Abstract:
1. In a code division multiple access communication system, a method comprising: determining, at a controller of a receiver, a rate of change of a carrier to interference ratio (C/I) of a communication channel carrying data received at the receiver; and determining a gain level of said communication channel based on said rate of change of said C/I for transmission of data over said communication channel to said receiver, wherein the gain level is based on a data rate of encoded information and a power level; determining a mobility level of said communication channel; determining whether said determined mobility level meets a low mobility threshold, wherein said determining said gain level of said communication channel based on said rate of change of C/I depends on whether said determined mobility level meets said low mobility threshold; determining a mean C/I; and determining a value proportional to the determined mobility level based upon the mean C/I value and an instantaneous C/I value.
