Abstract:
A method for reducing feedback overhead in a wireless communications system is described. Channel quality indicator (CQI) values corresponding to a measured channel quality are received from one or more mobile communications devices. The mobile communications devices to be scheduled at a future time are estimated. CQI values are requested from the mobile communications devices that are estimated to be scheduled at a future time.
