Abstract
A method for downlink link adaptation includes receiving, from a satellite and at a user terminal, a first data packet data unit according to a first downlink modulation and coding scheme (MCS), computing error vector magnitude data associated with the first data packet data unit, generating, based on one or more of the error vector magnitude data, user terminal signal-to-noise-ratio feedback based on a constant times a previous user terminal signal-to-noise-ratio and a current user terminal signal-to-noise-ratio, and transmitting an uplink packet data unit having a downlink block error rate and the user terminal signal-to-noise-ratio feedback. A satellite runs a link adaptation algorithm based on the user terminal signal-to-noise-ratio feedback and block error rate to generate a second downlink MCS. The method includes receiving at the user terminal a second data packet data unit according to the second downlink MCS for the satellite-to-user-terminal downlink. Uplink link adaptation is also disclosed.
