Claim Text:
1. A method for performing link adaptation, comprising: performing at a base station in a wireless network, classifying transmissions from user equipment into a first group of time-critical traffic and a second group of non-time-critical traffic; determining a first Modulation and Coding Scheme (MCS) for the transmissions in the first group; determining a second MCS for the transmissions in the second group; measuring a success rate from P initial transmissions by a user equipment in the first group; estimating a block error rate based upon the success rate of a defined number of initial transmissions; increasing a current backoff parameter if the estimated block error rate is greater than a target block error rate to create a new backoff parameter; and decreasing the current backoff parameter if the estimated block error rate is less than the target block error rate to create the new backoff parameter.
