  • Method of performing feedback load reduction and related communication device
    Patent number: 8583161
    Abstract: A method of performing feedback load reduction for a mobile device in a wireless communication system is disclosed. The method comprises measuring a signal from the network to get Channel State Information (CSI); comparing the measured CSI with at least one threshold and determining one region where the CSI falls in from a plurality of regions divided by the at least one threshold and ranked in order; and sending a rank for the determined region to the network.
    Type: Grant
