Channel state information processing method and apparatus, and system

An apparatus, comprising a processor, and a memory, wherein

• the memory is configured to store an instruction, the processor is configured to execute the instruction stored in the memory, to cause a terminal to perform the following:
• receiving configuration information for channel state information measurement from a radio network device, wherein the configuration information comprises information about one or more resources for channel state information measurements to be performed by the terminal and indicates information about a measurement attribute of the one or more resources, wherein
• the configuration information for the channel state information measurements includes measurements for the radio network device and at least one another network device;
• the measurement attribute comprises X number of types of interference measurement, wherein X is an integer greater than or equal to 2, and the X number of types of interference measurement includes obtaining an unprecoded interference by using a resource of a non-zero power channel state information reference signal, and obtaining a precoded interference by using a non-zero power demodulation reference signal;
• and
• the channel state information measurement to be performed by the terminal comprises at least two different types of channel state information measurements to be performed by the terminal, the at least two different types of channel state information measurements including one channel measurement and one interference measurement;
• and
• measuring channel state information based on the configuration information, and feeding back the channel state information.
