System and Method for Channel Measurement and Interference Measurement in Wireless Network

A user equipment (UE), comprising:

• one or more processors;
• and
• a non-transitory computer-readable storage medium storing programming for execution by the one or more processors, the programming including instructions to cause the UE to perform operations including:
• receiving control information of a first subset of a set of non-zero-power (NZP) channel state information (CSI) reference signal (CSI-RS) (NZP CSI-RS) resources, the control information being associated with a first CSI report;
• performing a channel measurement on the first subset of the set of NZP CSI-RS resources;
• performing an interference measurement, the interference measurement including at least measurement of other interference, the other interference being not associated with any interference transmission layer assumed by the UE for the first CSI report, and the other interference being on at least the first subset of the set of NZP CSI-RS resources;
• generating the first CSI report based on the channel measurement and the interference measurement;
• and
• transmitting the first CSI report to a base station.

A non-transitory computer-readable medium having instructions stored thereon that, when executed by a user equipment (UE), cause the UE to perform operations, the operations comprising:

• performing a channel measurement on the first subset of the set of NZP CSI-RS resources;
• performing an interference measurement, the interference measurement including at least measurement of other interference, the other interference being not associated with any interference transmission layer assumed by the UE for the first CSI report, and the other interference being on at least the first subset of the set of NZP CSI-RS resources;
• generating the first CSI report based on the channel measurement and the interference measurement;
• and
• transmitting the first CSI report to a base station.

A method, comprising:

• receiving, by a user equipment (UE), control information of a first subset of a set of non-zero-power (NZP) channel state information (CSI) reference signal (CSI-RS) (NZP CSI-RS) resources, the control information being associated with a first CSI report;
• performing, by a network element, a channel measurement on the first subset of the set of NZP CSI-RS resources;
• performing, by the network element, an interference measurement, the interference measurement including at least measurement of a first interference, the first interference being not associated with any interference transmission layer assumed by the network element for the first CSI report, and the first interference being on at least the first subset of the set of NZP CSI-RS resources;
• generating, by the network element, the first CSI report based on the channel measurement and the interference measurement;
• and
• transmitting, by the network element, the first CSI report to a network device.
