The present invention implements a method and system for dynamically adapting the modulation and coding scheme for radio links in a wireless communications network based on a retransmission environment model in order to maximize throughput and most efficiently allocate bandwidth resources. The present invention encompasses a refined calculus and methodology for deriving the link adaptation thresholds in a retransmission environment using a complex model and analysis of the retransmission environment. The present invention holds particular application for wireless data communications as opposed to real time data services because it is based on a retransmission model applicable primarily for data services. A critical component of this new link adaptation system is a "no transmission" cutoff mode that is selected for SIR below a base threshold value. This new mode prevents system instability and misallocation of bandwidth in a wireless communication system.       Recently Added Patents Breathing mask with an autonomous inflatable harness Navigation system with alternative route determination mechanism and method of operation thereof Closed loop communication Gaming tables with multiple player positions and common display Recording medium, playback device, and integrated circuit Controller and method employed in optical storage apparatus for generating control signals each having minimum transmission pulse length corresponding to more than one power symbol period Ion chromatography systems with flow-delay eluent recycle   Randomly Featured Patents Use of sodium 2-mercaptoethanesulfonate in surgery Method of preparing a multilayered solid wood panel Process and device for alignment of sheet material during transport Redundant steer-by-wire system Data transmission with non-uniform distribution of data rates for a multiple-input multiple-output (MIMO) system Female buckle portion Correlated electron memory Tendon extraction system Process for producing stainless steels Method for controlling peripheral device, program for executing same method, storage device storing same program, and computer, peripheral device and system for executing same method © 2006-2008 PatentGenius.
