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)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for channel state information feedback in a coordinated multi-point communication system","description":"A method of operating a wireless communication system (FIG. 4) is disclosed.
