Embodiments of the present invention relate to the technical field of communications. Provided are a channel measurement and feedback method, a network device, and a system. The method comprises: a first network device receives pilot port configuration information sent by a second network device, the pilot port configuration information being used for describing at least two pilot ports; measure, through the at least two pilot ports, a pilot signal sent by the second network device, and determine first information, the first information comprising at least one of second information of the first network device and third information of a third network device when it is assumed that the first network device and the third network device conduct spatial multiplexing on same time-frequency resources and communicate with the second network device, and the second information and the third information separately comprising at least one of used pilot port information, a used RI, a used PMI or a CQI of the first network device and the third network device; and feed back the first information to the second network device. The present invention improves the accuracy of channel measurement. |
