Radio Bearer Status Reporting for Uplink Resource Allocation

The patent segments the buffer status reporting by dividing radio bearers into different groups (first group and second group) with different priorities. Different status information is reported for different groups, allowing precise reporting of high-priority bearers while simplifying reporting for low-priority bearers. This resolves the contradiction by providing detailed status only where necessary.

The patent applies different reporting qualities to different radio bearers based on their priority. High-priority bearers receive detailed status reporting (token count, buffer size), while low-priority bearers receive simplified reporting. This local differentiation achieves precise reporting for critical services without the overhead of detailed reporting for all bearers.

The patent implements feedback by reporting token count information from the token bucket mechanism to the base station. The UE monitors its buffer status and token availability, then feeds back this information through status reports. The base station uses this feedback to adjust uplink resource allocation dynamically, ensuring resources are allocated according to actual buffer needs and service priorities, thus improving resource utilization efficiency.

The UE autonomously monitors its own buffer status and determines when to trigger status reports based on changes in buffer size or token count. This self-service approach allows the UE to provide accurate status information without continuous base station polling, reducing signaling overhead while maintaining information accuracy for efficient resource allocation.

The patent segments radio bearers into priority groups and applies different reporting strategies to each group. Only high-priority bearers trigger detailed status reports with token count information, while low-priority bearers use simplified reporting. This segmentation reduces the quantity of status reports transmitted while maintaining precision for critical services.

The patent applies partial action by reporting detailed status information only for high-priority radio bearers that require guaranteed bit rates, rather than for all bearers. This selective detailed reporting provides sufficient precision for resource allocation decisions while minimizing signaling overhead by omitting detailed reports for low-priority bearers.
