LAYER-SPECIFIC FEEDBACK PERIODICITY - A simplified explanation of the abstract
This abstract first appeared for US patent application 18246025 titled 'LAYER-SPECIFIC FEEDBACK PERIODICITY
Simplified Explanation
The patent application describes methods, systems, and devices for wireless communications.
- The invention focuses on a user equipment (UE) receiving a channel state information (CSI) configuration from a base station.
- The CSI configuration indicates different feedback reporting periodicities for dominant and non-dominant spatial layers.
- The UE transmits CSI reports for the dominant and non-dominant spatial layers according to their respective feedback reporting periodicities.
- In some cases, the UE may be triggered by downlink control information to report CSI for the dominant spatial layer.
- The CSI configuration may also indicate different codebooks for the dominant and non-dominant spatial layers.
Original Abstract Submitted
Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a channel state information (CSI) configuration indicating a first feedback reporting periodicity for a dominant, or strong, spatial layer and a second feedback reporting periodicity for a non-dominant, or weak, spatial layer. The UE may transmit a first CSI report for at least the dominant spatial layer according to the first feedback reporting periodicity. The UE may transmit a second CSI report for the non-dominant spatial layer according to the second feedback reporting periodicity. In some cases, for aperiodic reporting, the UE may be triggered by downlink control information to report CSI for the dominant spatial layer. In some cases, the CSI configuration may indicate different codebooks for the dominant and non-dominant spatial layers.
