User Equipment and Base Station Event-Based Random Access Prioritization

The patent applies parameter changes by introducing differentiated random access transmission parameters (such as power ramping steps, backoff values, and preamble selection) based on service types and triggering events. The network configures multiple sets of parameters corresponding to different services (e.g., URLLC, eMBB, mMTC) and events (e.g., handover, initial access, beam failure recovery), allowing the UE to select appropriate parameters dynamically. This resolves the contradiction by improving reliability through service-specific optimization while managing complexity through structured configuration tables and event-based selection rules.

The patent applies segmentation by dividing the random access configuration into multiple independent parameter sets, each associated with specific service types and triggering events. The network configures separate parameter groups for different services (URLLC, eMBB, mMTC) and events (handover, initial access, beam failure), allowing selective activation and reduced signaling overhead by only transmitting relevant configurations. This resolves the contradiction by enabling service-specific adaptability while reducing overhead through modular, event-driven configuration management.

The patent applies dynamics by implementing dynamic backoff parameter adjustment based on service priority and network conditions. High-priority services (e.g., URLLC) are assigned smaller backoff values and faster power ramping to reduce latency, while lower-priority services use larger backoff values to reduce collision probability. The network can dynamically adjust these parameters based on current load conditions, service requirements, and event types. This resolves the contradiction by making the system adaptive - reducing latency for critical services while managing overall collision probability through differentiated and dynamic parameter control.
