Channel state information reporting method and apparatus
摘要
說明書
The terminal device receives third indication information, where the third indication information is used to indicate that the jth CSI-IM resource in the N1 CSI-IM resources is the first-type CSI-IM resource or the second-type CSI-IM resource, where j∈{1, . . . ,N1}.
Specifically, the first-type CSI-IM resource and the second-type CSI-IM resource in the N1 CSI-IM resources may be predefined, or may be determined according to a predefined rule. For example, a CSI-IM resource whose resource index is an odd number is a first-type CSI-IM resource, and a CSI-IM resource whose resource index is an even number is a second-type CSI-IM resource. For another example, the first p CSI-IM resources are first-type CSI-IM resources and the last q CSI-IM resources are second-type CSI-IM resources in ascending order of resource indexes. For another example, the first p CSI-IM resources are second-type CSI-IM resources and the last q CSI-IM resources are first-type CSI-IM resources in ascending order of resource indexes, where both p and q are positive integers less than N1.
