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.

The network device 102 may communicate with a plurality of terminal devices, for example, the network device 102 may communicate with a terminal device 116 and a terminal device 122. However, it may be understood that the network device 102 may communicate with any quantity of terminal devices that are similar to the terminal device 116 or the terminal device 122. The terminal device 116 and the terminal device 122 each may be, for example, a cellular phone, a smartphone, a portable computer, a handheld communications device, a handheld computing device, a satellite radio apparatus, a global positioning system, a PDA, and/or any other suitable device used for communication in the wireless communications system 100.

As shown in FIG. 1, the terminal device 116 communicates with the antenna 112 and the antenna 114. The antenna 112 and the antenna 114 each send information to the terminal device 116 over a forward link 118, and receive information from the terminal device 116 over a reverse link 120. In addition, the terminal device 122 communicates with the antenna 104 and the antenna 106. The antenna 104 and the antenna 106 each send information to the terminal device 122 over a forward link 124, and receive information from the terminal device 122 over a reverse link 126.

For example, in a frequency division duplex FDD system, for example, the forward link 118 and the reverse link 120 may use different frequency bands, and the forward link 124 and the reverse link 126 may use different frequency bands.
