Abstract:
1. A method for use by a wireless unit and employing criteria for biasing a binary decision by adjustment of a threshold used for the binary decision to provide unequal protection of a received communication, comprising the steps of: receiving the communication in a given channel; obtaining a signal to interference ratio (SIR) of the communication channel; comparing the SIR against the threshold, said threshold being adjusted based on criteria including at least a noise component and being selected to bias the binary decision toward a determination that a received data communication is interpreted as having an error; and generating one of a non-acknowledgement (NACK) or an acknowledgement (ACK) based only on the result of the comparison of the SIR with the threshold; wherein the determination of the received communication as having no error being responsive to said SIR being greater than said threshold and independent of and eliminating a need for an error detection operation on the received communication which is accepted by the wireless unit.
