CSI Reporting for Multi-Panel Beam Grouping

The patent segments the beam reporting process into multiple independent components: beam measurement, beam grouping based on spatial relationships, beam selection criteria, and hierarchical reporting structures. This segmentation allows the system to handle complex multi-panel and multi-TRP scenarios by breaking down the overall beam management into manageable, independent tasks that can be processed separately and combined, thereby improving spectral efficiency without proportionally increasing reporting complexity.

The patent introduces spatial dimensionality into beam reporting by organizing beams into groups based on their spatial relationships (e.g., beams from different panels, beams associated with different TRPs). This spatial grouping adds a new dimension to the reporting structure, allowing the system to efficiently represent and manage beams in multi-panel and multi-TRP scenarios without linearly increasing reporting overhead, thus improving spectral efficiency while controlling complexity.

The patent extracts and reports only the most relevant beam information by implementing selection criteria that identify beams meeting specific thresholds (e.g., RSRP thresholds, spatial relationship criteria). Instead of reporting all measured beams, the system extracts only those beams that contribute meaningfully to RANK transmission, thereby reducing reporting overhead while maintaining or improving transmission performance. This extraction principle allows the system to focus resources on reporting high-value beam information.

The patent implements partial reporting by allowing the system to report a subset of beams based on configured criteria rather than requiring complete beam information. The reporting configuration can specify partial sets of beams (e.g., top N beams, beams above threshold) to be reported, enabling the system to achieve sufficient RANK transmission capability with reduced reporting overhead. This partial action principle balances transmission performance requirements with overhead constraints.

The patent implements dynamic beam grouping where grouping criteria and parameters can be adjusted based on channel conditions, device capabilities, and network requirements. The system can dynamically modify grouping thresholds, selection criteria, and reporting configurations to optimize the balance between operational simplicity and alignment precision. This dynamic approach allows the system to adapt to varying conditions, maintaining ease of operation while preserving beam alignment precision when needed.

The patent employs parameter changes in beam grouping by allowing configuration of multiple grouping parameters (e.g., RSRP thresholds, spatial relationship parameters, beam selection criteria) that can be adjusted to achieve desired performance. By changing these parameters based on system state and requirements, the system can optimize the trade-off between reporting configuration simplicity and beam alignment precision. Different parameter sets can be applied for different scenarios, enabling flexible optimization without compromising fundamental performance.
