Uplink Buffer Status Reporting Grouping for Wireless Scheduling

The patent segments the buffer status report by dividing service streams into different priority groups (first priority, second priority, etc.). Instead of reporting all service streams uniformly, the UE selectively reports buffer status information for specific priority groups based on triggering conditions. This segmentation allows the system to provide sufficient scheduling information for high-priority services while reducing overall signaling overhead by omitting low-priority services when resources are constrained.

The patent implements partial reporting by introducing triggering mechanisms that determine whether buffer status information should be reported. The UE monitors buffer status and only triggers reports when specific conditions are met (e.g., buffer threshold exceeded, latency requirement violated). This partial action approach ensures that scheduling information is provided when necessary while avoiding excessive signaling when buffer status is already satisfactory or resources are limited.

The patent segments service streams into distinct priority groups (first priority service streams, second priority service streams, etc.) and assigns different reporting treatments to each segment. The buffer status report structure is segmented to include separate buffer size indications for different priority groups. This segmentation enables QoS-aware scheduling by allowing the base station to differentiate resource allocation based on service priority while maintaining a relatively simple reporting structure that follows existing protocol formats.

The patent enhances the existing buffer status report mechanism to serve multiple functions: it simultaneously provides buffer size information, service priority differentiation, and triggering condition indicators within a unified reporting framework. The same reporting structure can accommodate different priority levels and triggering scenarios without requiring separate reporting mechanisms for each case, thereby reducing overall system complexity while maintaining QoS differentiation capability.
