Solution Overview

Problem

Current Long Term Evolution (LTE) wireless communication networks face limitations in baseband processor performance due to computational speed and task complexity, leading to incomplete task execution and unfair service distribution among user equipment, with existing solutions being costly or insufficiently effective.

Innovation Solution

A method and system for scheduling tasks in a baseband processor that assigns priority to tasks based on parameters affecting processing time, using a prioritizer and scheduler to evaluate and compare parameters such as distance, HARQ status, and CoMP access, to optimize task execution order.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If processor computational power is increased to improve task completion speed, then processing performance is improved, but system cost increases

Engineering Contradiction:
Improvetask completion speedVSAvoidprocessor computational power
Core Design Contradiction:
ProductivityVSQuantity of substance

Solution Approach 1:

The patent applies preliminary action by evaluating multiple parameters (distance, HARQ status, CoMP access, channel conditions) before scheduling tasks. The baseband processor assesses these parameters in advance to determine optimal task execution order, ensuring that critical tasks are prioritized before time expires, thereby improving completion speed without requiring additional computational power.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent changes scheduling parameters dynamically based on real-time conditions. Instead of fixed scheduling, the system adjusts task priorities based on varying parameters such as user equipment distance, HARQ retransmission status, and channel quality. This dynamic parameter adjustment optimizes task completion within available time frames without increasing hardware capabilities.

Inventive Principle:
Principle #35Parameter changes

2Adaptability or versatility

If more tasks are scheduled to improve service coverage, then service fairness is improved, but task completion reliability deteriorates due to time constraints

Engineering Contradiction:
Improveservice coverageVSAvoidtask completion reliability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system dynamically changes scheduling parameters based on real-time assessments of distance, HARQ status, and channel conditions. This allows the baseband processor to adapt task scheduling to current system state, ensuring that service coverage is maintained while prioritizing tasks that can be completed reliably within time constraints.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent implements feedback mechanisms by continuously monitoring task completion status and scheduling outcomes. The system uses this feedback to adjust future scheduling decisions, learning from past performance to improve both service coverage and completion reliability. The scheduler adapts based on observed patterns in task execution success rates.

Inventive Principle:
Principle #23Feedback

3Loss of time

If processing time is reduced to meet time frame requirements, then task completion speed is improved, but processing quality deteriorates

Engineering Contradiction:
Improveprocessing timeVSAvoidprocessing quality
Core Design Contradiction:
Loss of timeVSManufacturing precision

Solution Approach 1:

The system performs preliminary evaluation of processing requirements and complexity before actual task execution. By assessing parameters such as task type, user equipment conditions, and available time in advance, the scheduler can prioritize tasks that require longer processing and allocate sufficient time to maintain quality, while quickly handling simpler tasks that meet time frame requirements.

Inventive Principle:
Principle #10Preliminary action
