PORT SELECTION FOR CHANNEL STATE FEEDBACK WITH ANALOG FEEDFORWARD - A simplified explanation of the abstract
This abstract first appeared for US patent application 17754719 titled 'PORT SELECTION FOR CHANNEL STATE FEEDBACK WITH ANALOG FEEDFORWARD
Simplified Explanation
The patent application describes techniques for selecting ports for channel state feedback with analog feedforward.
- The user equipment (UE) selects one or more channel state information reference signals (CSI-RS) ports for reporting CSI.
- The port selection is based on a grouping of the CSI-RS ports.
- The UE determines a precoding matrix indicator (PMI) formed by a linear combination of the selected CSI-RS ports.
- The UE computes wideband linear combination coefficients for the selected CSI-RS ports.
- The UE provides the selected CSI-RS ports and computed coefficients to a base station (BS) in a CSI report.
Potential applications of this technology:
- Wireless communication systems
- 5G networks
- Mobile devices
Problems solved by this technology:
- Efficient selection of ports for channel state feedback
- Improved precoding matrix indicator determination
- Enhanced communication performance
Benefits of this technology:
- Improved channel state feedback accuracy
- Enhanced system performance and capacity
- Better utilization of available resources
Original Abstract Submitted
Certain aspects of the present disclosure provide techniques for port selection for channel state feedback with analog feedforward. A method that may be performed by a user equipment (UE) includes selecting one or more channel state information reference signals (CSI-RS) ports, of a plurality of CSI-RS ports, for the UE to report CSI. The port selection includes selecting any of the plurality of CSI-RS ports for selecting CSI-RS based on a grouping of the plurality of CSI-RS ports. The UE determines a precoding matrix indicator (PMI) formed by a linear combination of the one or more selected CSI-RS ports. The UE computes at least wideband linear combination coefficients for the selected CSI-RS ports. The UE provides the selected one or more CSI-RS ports and the computed wideband linear combination coefficients to a base station (BS) in a CSI report.
