摘要

This application provides a channel state information reporting method and apparatus. The method includes: A terminal device receives M pieces of downlink control information, where first downlink control information in the M pieces of downlink control information indicates a first channel state information configuration, the first channel state information configuration is associated with a first channel state information interference measurement CSI-IM resource group, and the first CSI-IM resource group includes N1 CSI-IM resources, where M and N1 are positive integers, and N1 is greater than 1; and the terminal device measures a target CSI-IM resource, and reports channel state information, where the target CSI-IM resource is determined by the terminal device from the N1 CSI-IM resources based on M, and a quantity of target CSI-IM resources is less than N1.

說(shuō)明書(shū)

SINR ? ? 1 = ? h 1 ? 2 I 2 + I 0 ,
and calculate that an SINR of the data stream of the base station 2 is

SINR ? ? 2 = ? h 2 ? 2 I 1 + I 0 .
The terminal device reports a CQI 1 and a CQI 2 to the base station based on the SINR 1 and the SINR 2. It should be understood that the above formula is merely an example described for ease of understanding, and an SINR may be alternatively calculated by using another expression. This is not limited in the embodiments of this application.
