Channel state information reporting method and apparatus
摘要
說明書
In one embodiment, when M≥2, second downlink control information in the M pieces of downlink control information indicates a second channel state information configuration, the second channel state information configuration is associated with a second CSI-IM resource group, the second CSI-IM resource group includes N2 CSI-IM resources, and there is an association relationship between the first channel state information configuration and the second channel state information configuration, where N2 is a positive integer.
In one embodiment, the first channel state information configuration is the same as the second channel state information configuration; or
the first channel state information configuration and the second channel state information configuration are used for a same transmission mechanism set, and the transmission mechanism set includes a multi-station joint transmission mechanism and a single-station transmission mechanism; or
the first channel state information configuration carries first indication information, or the first downlink control information carries the first indication information, and the first indication information is used to indicate that the first channel state information configuration is associated with the second channel state information configuration.
In one embodiment, the N1 CSI-IM resources include a first-type CSI-IM resource and a second-type CSI-IM resource, the first-type CSI-IM resource is used to measure interference information in a multi-station joint transmission mechanism, and the second-type CSI-IM resource is used to measure interference information in a single-station transmission mechanism.
