Method and device for configuring channel state information feedback, method and device for measurement and feedback

A measuring method based on Channel State Information (CSI) feedback configuring information, comprising:

• acquiring, by a terminal, multiple CSI processes configured, and performing measurement in accordance with the multiple CSI processes, wherein each of the multiple CSI processes comprises at least channel measuring information and interference measuring information;
• the channel measuring information comprises one or more sets of nonzero-power (NZP) CSI Reference Signal (CSI-RS) configuring or indicating information;
• and
• the interference measuring information comprises at least one of:
• one or more sets of interference measurement resource (IMR) configuring information or IMR indicating information;
• and
• one or more sets of interference measurement compensating NZP CSI-RS configuring information,
• wherein P CSI processes are formed with one or more sets of channel measuring information and one or more sets of interference measuring information, and the terminal is notified, via a P-bit bitmap, to feed back Q of the P CSI processes, wherein the Q is a number of bits with a value of 1 in the P-bit bitmap or a number of bits with a value of 0 in the P-bit bitmap, both the P and the Q being natural numbers.

A device for configuring Channel State Information (CSI) feedback, comprising:

• a processor;
• and
• a memory storing instructions executable by the processor,
• wherein the processor is
• configured for:
• configuring, for a terminal, multiple CSI processes each comprising at least channel measuring information and interference measuring information, wherein
• the channel measuring information comprises one or more sets of nonzero-power (NZP) CSI Reference Signal (CSI-RS) configuring or indicating information;
• and
• the interference measuring information comprises at least one of:
• one or more sets of interference measurement resource (IMR) configuring information or IMR indicating information;
• and
• one or more sets of interference measurement compensating NZP CSI-RS configuring information,
• wherein the processor is further configured for:
• forming P CSI processes with one or more sets of channel measuring information and one or more sets of interference measuring information, and notifying, via a P-bit bitmap, the terminal to feed back Q of the P CSI processes, wherein the Q is a number of bits with a value of 1 in the P-bit bitmap or a number of bits with a value of 0 in the P-bit bitmap, both the P and the Q being natural numbers.
