Method for reporting channel quality

A method of receiving a channel quality report from a user equipment (UE), the method comprising:

• transmitting, to the UE, a channel state information-interference measurement (CSI-IM) configuration for first and second transmission points (TPs),
• wherein the CSI-IM configuration includes configurations for at least three CSI-IMs, and
• wherein the configurations for the at least three CSI-IMs includes a configuration for first CSI-IM for measuring interference caused by the second TP toward the first TP, a configuration for second CSI-IM for measuring interference caused by the first TP toward the second TP, and a configuration for third CSI-IM for measuring interference from another interference source;
• and
• receiving, from the UE, a channel quality indicator (CQI) measured using the first CSI-IM and a CQI measured using the third CSI-IM.

A user equipment (UE) reporting channel quality, the UE comprising:

• a receiver to receive a channel state information-interference measurement (CSI-IM) configuration for first and second transmission points (TPs),
• wherein the CSI-IM configuration includes configurations for at least three CSI-IMs, and
• wherein the configurations for the at least three CSI-IMs includes a configuration for first CSI-IM for measuring interference caused by the second TP toward the first TP, a configuration for second CSI-IM for measuring interference caused by the first TP toward the second TP, and a configuration for third CSI-IM for measuring interference from another interference source;
• and
• a transmitter to transmit a channel quality indicator (CQI) measured using the first CSI-IM and a CQI measured using the third CSI-IM.

A base station receiving a channel quality report from a user equipment (UE), the base station comprising:

• a transmitter to transmit, to the UE, a channel state information-interference measurement (CSI-IM) configuration for first and second transmission points (TPs),
• wherein the CSI-IM configuration includes configurations for at least three CSI-IMs, and
• wherein the configurations for the at least three CSI-IMs includes a configuration for first CSI-IM for measuring interference caused by the second TP toward the first TP, a configuration for second CSI-IM for measuring interference caused by the first TP toward the second TP, and a configuration for third CSI-IM for measuring interference from another interference source;
• and
• a receiver to receive, from the UE, a channel quality indicator (CQI) measured using the first CSI-IM and a CQI measured using the third CSI-IM.
