description The present invention relates to the field of communications technologies, and in particular, to a CSI reporting method, a CSI receiving method, and an apparatus, to resolve a technical problem that PUCCH resource overheads are relatively large during CSI reporting. In embodiments of the present invention, at least two PUCCH resources are configured for each downlink carrier group. CSI that needs to be reported in one uplink subframe may be obtained, and a format of a corresponding PUCCH resource is determined according to the to-be-reported CSI. For example, the determined format is referred to as a first format. Then, all of the to-be-reported CSI is reported after being added to a first first-format PUCCH resource.
