PRACH Repetition Resource Separation for NR Coverage Access

The patent segments PRACH resources into two distinct types: first PRACH resources for transmissions without repetition and second PRACH resources for transmissions with repetition. This segmentation allows the system to differentiate between single-shot and repeated transmissions, enabling optimized handling for each type and improving overall transmission success probability while maintaining manageable resource configuration complexity.

The patent introduces dynamic repetition mechanisms where the network can configure different repetition numbers for PRACH transmissions. The UE can adaptively select repetition counts based on coverage conditions, and the network can dynamically adjust resource allocations. This dynamic approach enhances transmission reliability in varying channel conditions without requiring overly complex static resource configurations.

By segmenting PRACH resources into first resources (without repetition) and second resources (with repetition), the patent prevents resource conflicts between different transmission types. Each resource type has dedicated time-frequency slots, eliminating the possibility of collisions between repeated and non-repeated transmissions. This segmentation maintains high resource utilization efficiency while enabling improved coverage performance through repetition when needed.

The patent applies different resource characteristics to different transmission scenarios: first PRACH resources are configured for scenarios where quick access is needed without repetition, while second PRACH resources are configured with repetition capabilities for coverage-enhanced scenarios. This local differentiation optimizes resource utilization for each specific use case, preventing waste while maintaining high coverage performance where required.

The patent segments PRACH configuration into two distinct resource sets with clear differentiation. First PRACH resources are configured with specific parameters for non-repeated transmissions, while second PRACH resources are configured with additional repetition-related parameters. This segmentation reduces resource conflicts by eliminating overlap scenarios, and the structured approach to configuration manages complexity through systematic organization rather than ad-hoc arrangements.

The patent creates a universal PRACH resource configuration framework that can handle both repeated and non-repeated transmissions through a unified configuration structure. The network can selectively activate appropriate resource types based on deployment requirements, and the UE can adapt to different resource types using standardized procedures. This multi-functionality approach reduces configuration complexity by providing a single versatile framework rather than requiring separate independent configurations for each transmission type.
