DUAL CODEBOOK CONFIGURATION AND CSI COMBINING FOR LARGE SCALE ACTIVE ANTENNA SYSTEMS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240014872 titled 'DUAL CODEBOOK CONFIGURATION AND CSI COMBINING FOR LARGE SCALE ACTIVE ANTENNA SYSTEMS
Simplified Explanation
The abstract of this patent application describes a method, network node, and wireless device for configuring dual codebooks and combining channel state information (CSI) in large-scale active antenna systems (AAS). The method involves triggering the wireless device to transmit a horizontal CSI report and a vertical CSI report, which respectively represent the horizontal and vertical directions of the antenna array. The horizontal CSI set is mapped to a row of the array, while the vertical CSI set is mapped to a column of the array. The network node receives these reports and combines the horizontal and vertical CSI sets into a combined CSI set for scheduling and beamforming.
- The patent application proposes a method for configuring dual codebooks and combining CSI in large-scale AAS.
- The wireless device is triggered to transmit separate horizontal and vertical CSI reports.
- The horizontal CSI set represents the horizontal direction of the antenna array and is mapped to a row of the array.
- The vertical CSI set represents the vertical direction of the array and is mapped to a column of the array.
- The network node receives the horizontal and vertical CSI reports from the wireless device.
- The network node combines the horizontal and vertical CSI sets into a combined CSI set.
- The combined CSI set is used for scheduling and beamforming in the AAS.
Potential applications of this technology:
- Large-scale active antenna systems (AAS) in wireless communication networks.
- Beamforming and scheduling in AAS for improved signal quality and coverage.
- Wireless networks requiring efficient channel state information (CSI) combining.
Problems solved by this technology:
- Efficient configuration of dual codebooks for AAS.
- Accurate representation of channel state information (CSI) in both horizontal and vertical directions.
- Effective combining of horizontal and vertical CSI sets for scheduling and beamforming.
Benefits of this technology:
- Improved signal quality and coverage in large-scale AAS.
- Enhanced capacity and throughput in wireless communication networks.
- Efficient utilization of antenna arrays for beamforming and scheduling.
Original Abstract Submitted
a method, network node and wireless device (wd) for dual codebook configuration and channel state information (csi) combining for large scale active antenna systems (aas) are disclosed. according to one aspect, a method in a network node includes triggering the wd to transmit in succession or simultaneously, a horizontal csi report reporting a horizontal csi set for a horizontal direction of the array and a vertical csi report reporting a vertical csi set for a vertical direction of the array, the horizontal csi set being mapped to a row of the array and the vertical csi set being mapped to a column of the array. the method also includes receiving the horizontal and vertical csi reports from the wd, and combining the horizontal and vertical csi sets into a combined csi set for at least one of scheduling and beamforming.
