METHODS, APPARATUSES, AND COMPUTER PROGRAMS FOR LINK ADAPTATION

Abstract:

Apparatus and methods for link adaptation for downlink transmissions in which the quality of the downlink radio channel is predicted with improved accuracy. For example, predicted channel gains are determined based on uplink transmissions on a per frequency sub-band basis and these predicated channel gains are then used in a link adaptation process for a downlink transmission.
