Patent ID: 8688054

Claim:
A base station comprising: a transmitter configured to transmit data packets; an adaptive correction term generator configured to receive positive acknowledgement (ACK)/negative acknowledgement (NACK) messages associated with the data packets, and to produce an adaptive bias term based upon the ACK/NACK messages in order to achieve a target block error rate (BLER) of the data packets; a bias determination unit configured to receive the adaptive bias term from the adaptive correction term generator and provide a CQI bias signal; a summer configured to receive channel quality indicators (CQIs), and further configured to bias the CQIs based on the CQI bias signal; a CQI to transport format (TF) map unit configured to map the biased CQIs to TFs, wherein the transmitter transmits the data packets according to the TFs; and a loop controller, coupled to the bias determination unit and the adaptive correction term generator, for controlling an operation of the adaptive correction term generator by issuing a hold signal to suspend the operation of the adaptive correction term generator such that a predetermined default correction term is used instead of the adaptive bias term while the hold signal is asserted based upon at least one of a generated transport format (GTF) determined by the base station, a CQI expected (CQIE) value used for a given packet, an equivalent CQI (ECQI) corresponding to channel quality associated with the GTF, a new data indicator (NDI) determined by the transmitter, or a cyclic redundancy check (CRC) indication of whether or not a transport block was received in error.
