CSI Resource Pair Grouping for Multi-TRP Hypothesis Evaluation

The patent segments the hypothesis evaluation process by introducing a hypothesis group ID that divides multiple hypotheses into distinct groups. Each hypothesis group is associated with a specific TRP or TRP combination, allowing the UE to evaluate hypotheses in an organized manner. This segmentation reduces the complexity of managing multiple CSI RS resources for multi-TRP deployment by structuring the hypothesis evaluation into manageable groups rather than treating all hypotheses as a single complex set.

The patent merges the hypothesis evaluation results by selecting a single best hypothesis group ID from multiple evaluated groups. Instead of reporting separate CSI for each hypothesis independently, the UE evaluates multiple hypothesis groups and reports only the best one along with its associated CSI. This merging approach maintains CSI reporting accuracy by considering multiple hypotheses while reducing signaling overhead by consolidating the report to a single best selection rather than transmitting all hypothesis evaluations.

The patent applies preliminary action by having the UE pre-configure multiple hypothesis groups with their associated CSI RS resources and TCI states before actual CSI reporting. The hypothesis groups are established in advance based on configured TCI states and CSI RS resource sets. This preliminary setup allows the UE to quickly evaluate and select the best hypothesis group during reporting without extensive real-time processing, thereby improving throughput while minimizing additional processing time.
