Abstract:
A method of operating a wireless communication system (FIG. 4) is disclosed. The method includes receiving a plurality of reference signals from a respective plurality of transceivers (402). Each, of the plurality of reference signals is measured to produce a respective plurality of channel state information (CSI) measurements (404). An aggregated channel quality indicator (CQI) is calculated from measuring the plurality of reference signals (406). The aggregated CQI is transmitted to at least one transceiver of the respective plurality of transceivers (408).
