Cell Selection Thresholds for RACH Resource Allocation in 5G NR

The patent applies parameter changes by introducing a cell selection threshold parameter that filters SS blocks based on their quality. The UE measures RSRP of detected SS blocks and compares against this threshold, selecting only those SS blocks that meet both the threshold requirement and the target received power requirement. This parameter-based filtering resolves the contradiction by maintaining quality standards while preserving flexibility within those standards.

The patent applies segmentation by dividing the cell quality assessment into distinct stages: first detecting and measuring individual SS blocks, then filtering based on threshold criteria, and finally averaging only the qualifying SS block measurements. This segmented approach improves measurement precision by ensuring only high-quality SS blocks contribute to the average, while managing complexity through a structured, stepwise process with clear decision points.

The patent applies parameter changes by introducing a quality threshold parameter that filters the pool of available SS blocks and their associated RACH resources. The UE measures RSRP of detected SS blocks, compares against the cell selection threshold, and selects only those SS blocks meeting both the threshold and target received power requirements. This parameter-based filtering improves downlink transmission beam quality while managing the quantity of available resources through intelligent selection criteria.
