METHOD AND APPARATUS FOR SELECTION OF LINEAR COMBINATION COEFFICIENTS FOR PRECODING IN FREQUENCY-SELECTIVE CHANNELS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17729457 titled 'METHOD AND APPARATUS FOR SELECTION OF LINEAR COMBINATION COEFFICIENTS FOR PRECODING IN FREQUENCY-SELECTIVE CHANNELS
Simplified Explanation
The patent application describes a method for providing implicit channel state information (CSI) feedback from a user equipment (UE) to a base station. The method involves determining a precoding matrix indicator (PMI) selection decision metric and selecting a method for selecting PMI indices based on sub-bands configured by the base station. The selected method can be a sub-band linear combination coefficient (LCC) selection method, a wideband (WB) LCC selection method, or a sub-band group (SBG) LCC selection method. The determined PMI indices are then transmitted to the base station.
- The method determines a metric for selecting a precoding matrix indicator (PMI).
- The method selects a method for selecting PMI indices based on sub-bands configured by the base station.
- The selected method can be a sub-band linear combination coefficient (LCC) selection method, a wideband (WB) LCC selection method, or a sub-band group (SBG) LCC selection method.
- PMI indices are determined using the selected method.
- The determined PMI indices are transmitted to the base station.
Potential Applications
- Wireless communication systems
- 5G networks
- Mobile devices
Problems Solved
- Efficient feedback of channel state information (CSI) from user equipment (UE) to base station
- Selection of precoding matrix indicator (PMI) indices based on sub-bands configured by the base station
Benefits
- Improved wireless communication performance
- Enhanced system capacity and throughput
- Reduced interference and improved signal quality
Original Abstract Submitted
The disclosure provides a method of providing implicit channel state information (CSI) feedback from a user equipment (UE). The method includes determining a precoding matrix indicator (PMI) selection decision metric, selecting one of a sub-band (SB) linear combination coefficient (LCC) selection method, a wideband (WB) LCC selection method, or a sub-band group (SBG) LCC selection method, based on the determined PMI selection decision metric, determining, using the selected LCC selection method, PMI indices based on sub-bands configured by a base station, and transmitting the determined PMI indices to the base station.
