US 11,888,563 B2 · Channel state information reporting method and apparatus

Abstract

This application provides a channel state information reporting method and apparatus. The method includes: A terminal device receives M pieces of downlink control information, where first downlink control information in the M pieces of downlink control information indicates a first channel state information configuration, the first channel state information configuration is associated with a first channel state information interference measurement CSI-IM resource group, and the first CSI-IM resource group includes N1 CSI-IM resources, where M and N1 are positive integers, and N1 is greater than 1; and the terminal device measures a target CSI-IM resource, and reports channel state information, where the target CSI-IM resource is determined by the terminal device from the N1 CSI-IM resources based on M, and a quantity of target CSI-IM resources is less than N1.

Dependent claims

A channel state information reporting method, comprising:

receiving, by a terminal device, M pieces of downlink control information, wherein first downlink control information in the M pieces of downlink control information indicates a first channel state information configuration associated with a first channel state information interference measurement (CSI-IM) resource group, and wherein the first CSI-IM resource group comprises N1 CSI-IM resources, wherein M and N1 are positive integers, and wherein N1 is greater than 1;
and
measuring, by the terminal device, at least one target CSI-IM resource, and reporting channel state information, wherein the at least one target CSI-IM resource is determined by the terminal device from the N1 CSI-IM resources based on a value of M, and wherein a quantity of the at least one target CSI-IM resources is less than N1.

A channel state information reporting method, comprising:

determining, by a network device, a first channel state information configuration associated with K channel state information reference signal (CSI-RS) resources and N1 channel state information interference measurement resources, and wherein at least one of the K CSI-RS resources is associated with 1 of the N1′ CSI-IM resources, wherein K and N1 are positive integers, and 1≤N1′≤N1;
and
sending, by the network device, the first channel state information configuration to a terminal device.

A channel state information reporting apparatus, comprising:

a transceiver, configured to receive M pieces of downlink control information, wherein first downlink control information in the M pieces of downlink control information indicates a first channel state information configuration associated with a first channel state information interference measurement (CSI-IM) resource group, and wherein the first CSI-IM resource group comprises N1 CSI-IM resources, wherein M and N1 are positive integers, and N1 is greater than 1;
and
a processor, configured to:
measure at least one target CSI-IM resource, and report channel state information by using the transceiver, wherein the at least one target CSI-IM resource is determined by a terminal device from the N1 CSI-IM resources based on a value of M, and a quantity of the at least one target CSI-IM resources is less than N1.
