Abstract
A wireless communication network improves reverse link communication performance by changing one or more Automatic Repeat Request (ARQ) control settings as a function of measured or estimated reverse link loading. Control settings can be changed on a per-sector basis, allowing consideration of different loading conditions in different radio sectors of the network. Further, control settings can be changed for individual mobile stations, or selected groups of mobile stations, allowing different ARQ controls to be used for different mobile stations. By way of non-limiting example, a control circuit in a base station controller can be configured to take advantage of light reverse link loading conditions in a given radio sector by changing the ARQ control parameter(s) used for one or more mobile stations operating in that sector so that fewer ARQ retransmissions are required for those mobile stations to transmit reverse link data to the network.
