Abstract

A method for link adaptation is provided. Data associated with a user device is stored. A first number of scheduling blocks, SBs, required to transmit the stored data is estimated based at least in part on a first modulation and coding scheme (MCS). The first MCS corresponds to a first channel performance level. A second MCS is determined based at least in part on a link quality. The second MCS corresponds to a second channel performance level. A determination is made whether second channel performance level is less than the first channel performance level. An operating MCS is selected based at least in part on whether second channel performance level is less than the first channel performance level. The data is scheduled for transmission based at least in part on the selected operating MCS.
