Uplink Resource Prioritization for SR and Message A Overlap

The patent segments uplink radio resources into different sets based on priority levels. High-priority resources are allocated for critical random access procedures (Message A transmissions), while low-priority resources are allocated for other uplink data transmissions. This segmentation prevents resource conflicts and ensures reliable connection establishment without time loss.

The patent implements preliminary action by pre-configuring priority levels and resource allocation rules before random access procedures begin. The terminal device determines priority levels of logical channels in advance, and the network side pre-allocates resources based on these priorities, preventing resource overlaps and connection failures before they occur.

The patent applies local quality by assigning different priority levels to different logical channels based on their specific characteristics and requirements. Critical channels (e.g., for random access procedures) receive high priority, while non-critical channels receive low priority. This localized differentiation ensures fast transmission of critical data without requiring complex centralized control.

The patent changes the parameter of resource allocation from uniform to differentiated priority-based allocation. By introducing priority levels as a new parameter, the system can allocate resources dynamically based on data importance, achieving fast critical data transmission while maintaining manageable complexity through standardized priority classification.
