Multi-PDSCH Transmission With Quasi-Co-Located Antenna Ports

The patent merges the determination of large-scale properties across multiple antenna ports by establishing quasi-co-location relationships. Instead of independently measuring each antenna port's large-scale properties (delay spread, Doppler shift, average gain), the system groups antenna ports that share similar propagation characteristics and applies a single set of parameters to the group, thereby reducing processing time while maintaining measurement accuracy.

The patent creates universal large-scale property parameters that can be applied across multiple antenna ports simultaneously. By defining quasi-co-location relationships, a single set of large-scale properties serves multiple antenna ports, making the measurement process more efficient without sacrificing the precision needed for accurate signal processing.

The patent reduces device complexity by merging the processing of large-scale properties for multiple antenna ports into a unified determination process. The UE identifies quasi-co-location relationships and applies shared parameters, eliminating the need for separate processing chains for each antenna port while preserving measurement precision through proper parameter selection.

The patent segments antenna ports into quasi-co-location groups based on their propagation characteristics. This segmentation allows the system to apply different levels of processing detail appropriately - full independent analysis only where necessary, and grouped analysis where propagation conditions are similar, thereby reducing overall device complexity while maintaining precision where required.
