1. A method for calculating a CQI, comprising:
receiving, by a network device, a channel quality indicator (CQI) and a rank from a terminal device;
wherein the CQI is cauculated based on K ports, and the K is equal to a value of the rank, the value of the rank belongs to 1 to N, N is a number of ports in a channel state information-reference signal (CSI-RS) resource, and K and N are positive integers.
