Abstract
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 from a determination of channel estimation. The SIR is compared against a threshold, the threshold being selected to bias the decision toward a NACK as opposed to an ACK 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.
Claims22
A method for biasing criteria for binary decisions requiring unequal protection in a wireless communication system, comprising:
- receiving a communication in a given channel;
- obtaining a signal to interference ratio (SIR) of the communication channel;
- and
- comparing the SIR against a given threshold, said threshold being selected to bias the criteria toward a transmission of a (NACK) condition to indicate that a received communication should be retransmitted.
Apparatus for biasing criteria for binary decisions requiring unequal protection in a wireless communication system, comprising:
- means for receiving a communication in a given channel;
- means for obtaining a signal to interference ratio (SIR) of the communication channel;
- and
- means for comparing the SIR against a given threshold, said threshold being selected to bias the criteria toward a transmission of a (NACK) condition to indicate that a received communication should be retransmitted.
