Claim 0:
1. A channel state information transmission method, comprising:
receiving N reference signal groups and configuration information, wherein N is an integer greater than or equal to 2, wherein the configuration information indicates that the N reference signal groups comprise M channel measurement reference signal groups and N-M interference measurement reference signal groups, and wherein M is a positive integer less than N;
determining a first reference signal in the M reference signal groups; and
determining a second reference signal in the N-M reference signal groups based on the first reference signal, wherein the first reference signal and the second reference signal are reference signals in different groups in the N reference signal groups; and
sending channel state information, wherein the channel state information comprises a first resource index, a second resource index, and first channel quality information, the first resource index is a resource index of the first reference signal, the second resource index is a resource index of the second reference signal, and the first channel quality information is obtained by using the first reference signal as a signal and the second reference signal as interference.
