A method for wireless communication, comprising: obtaining a first channel quality indicator, CQI, backoff value based at least in part on a first set of acknowledgment messages associated with a first subframe of a first interval, said obtaining the first CQI backoff value comprises: scaling a number of positive acknowledgments in the first set of acknowledgment messages by a rank associated with the first subframe, scaling a number of negative acknowledgments in the first set of acknowledgment messages by the rank associated with the first subframe, and determining the first CQI backoff value based at least in part on the difference between the scaled number of positive acknowledgments in the first set of acknowledgment messages multiplied with a first boundary constant and the scaled number of negative acknowledgments in the first set of acknowledgment messages multiplied with a second boundary constant; setting a modulation and coding scheme, MCS, of a first subframe of a second interval using the first CQI backoff value; obtaining a second CQI backoff value based at least in part on a second set of acknowledgment messages associated with a second subframe of the first interval, said obtaining the second CQI backoff value comprises: scaling a difference between a number of positive acknowledgments in the first set of acknowledgment messages and a number of positive acknowledgments in the second set of acknowledgment messages by a rank associated with the first subframe and second subframe associated with the first interval, and determining the second CQI backoff value based at least in part on the scaled difference between the number of positive acknowledgments in the first set of acknowledgment messages and the number of positive acknowledgments in the second set of acknowledgment messages; and setting a MCS of the second subframe of the second interval using the second CQI backoff value. obtaining a first channel quality indicator, CQI, backoff value based at least in part on a first set of acknowledgment messages associated with a first subframe of a first interval, said obtaining the first CQI backoff value comprises: scaling a number of positive acknowledgments in the first set of acknowledgment messages by a rank associated with the first subframe, scaling a number of negative acknowledgments in the first set of acknowledgment messages by the rank associated with the first subframe, and determining the first CQI backoff value based at least in part on the difference between the scaled number of positive acknowledgments in the first set of acknowledgment messages multiplied with a first boundary constant and the scaled number of negative acknowledgments in the first set of acknowledgment messages multiplied with a second boundary constant;
