METHOD AND APPARATUS FOR PROVIDING BIASING CRITERIA FOR BINARY DECISIONS FOR USE IN WIRELESS COMMUNICATIONS TO ENHANCE PROTECTION

摘要

A CRITERION FOR BIASING A BINARY DECISION REQUIRING AN UNEQUAL PROTECTION WHICH UTILIZES A MEASURED SIGNAL TO INTERFERENCE RATIO (SIR). THE SIR MAY BE DERIVED (S3) FROM A DETERMINATION OF CHANNEL ESTIMATION (S2). THE SIR IS COMPARED AGAINST A THRESHOLD (S4), THE THRESHOLD BEING SELECTED TO BIAS THE DECISION TOWARD A NACK (S5) AS OPPOSED TO AN ACK (S9) DETERMINATION. THE TECHNIQUE IS ADVANTAGEOUS FOR PROVIDING BIASED BINARY DECISIONS FOR HIGH SPEED DOWNLINK PACKETS (HSDP) BUT MAY BE UTILIZED FOR BOTH UPLINK AND DOWNLINK APPLICATIONS.
