ABSTRACT:
A method and system for generating a channel quality indication (CQI) for a communication channel established between a transmitter and a receiver. A signal-to-interference ratio (SIR) estimate of the communication channel is calculated and a correction term is generated based on a data packet transmitted by the transmitter. A corrected SIR is generated by combining the SIR estimate and the first correction term. The corrected SIR is mapped to a CQI value. The CQI value is sent to the transmitter in order to adjust the configuration of the next data packet transmitted by the transmitter. The first correction term may be generated by subtracting a target packet error rate (PER) from a filtered binary signal derived from negative-acknowledgement (NACK) signals and acknowledgement (ACK) signals which respectfully indicate whether or not errors exist in data packets transmitted by the transmitter.
