Buffer Status Report Integrity Check Indicator for 5G Scheduling

Solution Overview

Problem

In 5G networks, the existing methods for reporting buffer status reports do not accurately reflect the amount of data to be sent by user equipment (UE) due to the increased air interface data load caused by integrity protection checks, which affects resource allocation by the base station.

Innovation Solution

A method is introduced where information related to the integrity-checking section is added to the buffer status report, allowing the UE to report memory data with or without the integrity-checking section counted, and the network side is informed of the UE's capability to support this reporting manner, enabling accurate data scheduling.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If integrity protection check is added to each PDCP SDU in 5G, then data security is improved, but air interface data load increases and buffer status reporting accuracy deteriorates

Engineering Contradiction:

Improvedata securityVSAvoidbuffer status reporting accuracy

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The patent introduces a dynamic reporting mechanism where the UE can switch between two reporting modes: first mode reports buffer status including integrity-checking section data, second mode reports buffer status excluding integrity-checking section data. The network can dynamically indicate which mode to use, allowing the system to adapt between security-focused reporting and efficiency-focused reporting based on current network conditions and requirements.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter being reported in the buffer status report by introducing an indicator field that specifies whether the reported buffer size includes or excludes the integrity-checking section data. This parameter change allows the same reporting mechanism to convey different types of buffer status information, resolving the contradiction between reporting accuracy and data load.

Inventive Principle:

Principle #35Parameter changes

2Measurement precision

If integrity-checking section data is included in buffer status report, then data scheduling accuracy is improved, but reporting overhead increases

Engineering Contradiction:

Improvedata scheduling accuracyVSAvoidreporting overhead

Core Design Contradiction:

Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent implements a dynamic reporting mechanism where the UE can switch between two reporting modes: first mode reports buffer status including integrity-checking section data, second mode reports buffer status excluding integrity-checking section data. The network can dynamically indicate which mode to use, allowing the system to adapt between security-focused reporting and efficiency-focused reporting based on current network conditions and requirements.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The buffer status report mechanism is designed to serve multiple functions: it can report both the total buffer size including integrity checks and the user data buffer size excluding integrity checks, depending on the indicator field value. This multi-functionality allows a single reporting mechanism to address both scheduling accuracy requirements and overhead reduction goals.

Inventive Principle:

Principle #6Universality (Multi-functionality)
