Channel state information reporting method and apparatus
摘要
說明書
It should be understood that a configuration method of another CSI configuration (for example, a second CSI configuration) is the same as a configuration method of the first CSI configuration. Details are not described herein again.
In an 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.
Specifically, if the terminal device receives at least two pieces of downlink control information sent by at least two network devices, and CSI configurations indicated by the at least two pieces of downlink control information are associated, it indicates that the at least two network devices need to schedule the terminal device at a same moment to perform data transmission. The first DCI indicates the first CSI configuration, the second DCI indicates the second CSI configuration, the first CSI configuration is associated with the N1 CSI-IM resources, the second CSI configuration is associated with the N2 CSI-IM resources, and there is an association relationship between the first CSI configuration and the second CSI configuration.
It should be understood that the association relationship specifically means that both the first CSI configuration and the second CSI configuration may be used for multi-TRP transmission. The association relationship may be implemented in a plurality of manners. This is not limited in this embodiment of this application.
