One or more non-transitory computer-readable media having instructions that, when executed by one or more processors, cause a user equipment (UE):
- identify, based on one or more messages received from a base station, a configuration of channel state information (CSI) measurement resources and a multiple-input, multiple-output (MIMO) codebook configuration having a frequency component configuration with parameters to select a subset of frequency domain (FD) components or a time domain (TD) component configuration with parameters to select a subset of TD components;
- perform measurements of the CSI measurement resources;
- select a plurality of components based on the MIMO codebook configuration and the measurements;
- and
- generate a CSI report corresponding to the plurality of components for transmission to the base station.
A user equipment (UE), comprising:
- radio frequency (RF) interface circuitry to detect channel state information (CSI) measurement resources from a base station;
- and
- one or more processors coupled to the RF interface circuitry to:
- identify a multiple-input, multiple-output (MIMO) codebook configuration having a frequency component configuration with parameters to select a subset of frequency domain (FD) components or a time domain (TD) component configuration with parameters to select a subset of TD components;
- perform measurements of the CSI measurement resources;
- determine linear combination (LC) coefficients for components based on the measurements;
- select one or more components from the components based on the LC coefficients and the MIMO codebook configuration;
- and
- generate a CSI report that includes information for the one or more components.
A method of configuring a channel state information (CSI) report, comprising:
- configuring, by a base station, CSI measurement resources for CSI measurement by a user equipment (UE);
- providing, by the base station, a multiple-input, multiple-output (MIMO) codebook configuration to the UE, the MIMO codebook configuration having a frequency component configuration with parameters to select a subset of frequency domain (FD) components or a time domain (TD) component configuration with parameters to select a subset of TD components;
- and
- triggering, by the base station, the UE to generate the CSI report.
