Abstract
Systems and methods for downlink scheduling in wireless communications systems are described. In some embodiments, a method includes: applying channel prediction at a transmitter for transmitting information to one or more mobile devices; predicting channel state information for a channel over which the information is transmitted, the channel state information being based, at least, on the channel prediction; determining a precoding matrix to apply to the information, the determining the precoding matrix being based, at least, on predicted channel state information; and scheduling transmission of the information to the one or more mobile devices based, at least, on an asymptotic ergodic rate for the one or more mobile devices. The asymptotic ergodic rate can be based on large-scale channel behavior and a maximum Doppler shift between the mobile devices.
