Channel state information reporting method and apparatus
摘要
說明書
when M≥2 and the target CSI-IM resource is the second-type CSI-IM resource, the terminal device measures interference information on the target CSI-IM resource, determines the channel state information based on the obtained interference information, and reports the channel state information.
In one embodiment, the first channel state information configuration is further associated with K channel state information reference signal CSI-RS resources, and at least one of the K CSI-RS resources is associated with N1 of the N1 CSI-IM resources, where K is a positive integer, and 1<N1′≤N1.
Specifically, the first CSI configuration is further associated with the K CSI-RS resources, and the K CSI-RS resources are used by the terminal device to measure channel information. One CSI-RS resource is associated with at least two CSI-IM resources.
It should be understood that, that one CSI-RS resource is associated with at least two CSI-IM resources means that when the CSI-RS resource is used to measure channel information, the terminal device measures at least one target CSI-IM resource in the CSI-IM resources associated with the CSI-RS resource, to obtain corresponding interference information. The channel information and the interference information are used to determine reported CSI, and may be specifically used to determine a CQI in the CSI. The target CSI-IM resource may be determined based on M.
