Induced incoherency for joint transmission

A user equipment configured for operation in a wireless network, the user equipment comprising

• a radio circuit configured to receive reference signals, or groups of reference signals, and to transmit channel state information to the wireless network, and a baseband processor configured to:
• measure a separate channel response for each of two or more reference signals or groups of reference signals, and report at least one aggregated channel quality indicator (CQI) using the radio circuit, wherein the at least one aggregated CQI is based on the measured channel responses and is based on an assumption that jointly transmitted signals corresponding to the measured channel responses will, on a per-channel response basis, combine in a non-coherent fashion at the user equipment (UE);
• wherein, the UE is configured to base the CQI reporting on a predetermined shared understanding between the UE and an evolved Node B (eNB) that a particular pattern of frequency selective relative phase shifts are applied to transmissions from two or more transmission points for which the UE is performing CSI reporting, wherein the two or more transmission points perform joint transmission and wherein the frequency selective relative phase shifts force the signals from two or more transmission points to combine in a non-coherent fashion at the UE.
