Solution Overview

Problem

In wireless communication systems, particularly in 5G networks, there is a challenge in accurately reporting buffer status to base stations, which affects data transmission efficiency and resource allocation, and existing methods do not adequately protect data integrity while efficiently using resources.

Innovation Solution

The solution involves an apparatus and method that allow terminals to transmit an exact buffer status report by including the sizes of PDCP, RLC, and MAC headers, determining the appropriate format for the report (short or long BSR), and applying integrity protection patterns to ensure data integrity, thereby reducing resource usage and enhancing transmission efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the buffer status report includes header sizes (PDCP, RLC, MAC), then the measurement precision of buffer status is improved, but the device complexity increases

Engineering Contradiction:
Improvebuffer status reporting accuracyVSAvoidreport format complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The buffer status report is segmented into multiple formats (short BSR, long BSR, short truncated BSR, long truncated BSR) based on the required precision and available resources. Each format includes different levels of header size information, allowing the system to select the appropriate segmentation level for different scenarios.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system dynamically determines which BSR format to use based on real-time conditions such as resource availability and precision requirements. The terminal selects between different report formats dynamically, adjusting the level of detail in header size information according to current system state.

Inventive Principle:
Principle #15Dynamics

2Reliability

If integrity protection is applied to all packets, then the reliability of data transmission is improved, but the use of energy and processing resources increases

Engineering Contradiction:
Improvedata integrity protectionVSAvoidprocessing resource consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

Integrity protection is applied selectively to specific packets or packet sets rather than uniformly to all packets. The system determines local quality requirements for different data flows and applies protection only where necessary, optimizing the balance between security and resource consumption.

Inventive Principle:
Principle #3Local quality
