Solution Overview

Problem

Wireless communication systems face challenges in efficiently utilizing the available spectrum and managing power amplifiers to transmit data with low latency, particularly for applications requiring seamless connectivity and minimal delay.

Innovation Solution

A transmitter configured to split transmission periods into scheduling time slots, with each dataset divided into two sub-datasets, where the first sub-dataset is transmitted with a lower bandwidth and shorter interruptions to meet latency requirements, and the second sub-dataset is transmitted with higher bandwidth, optimizing resource allocation and ensuring efficient use of earliest scheduling time slots.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If data is transmitted using a single high-bandwidth signal, then the data transmission speed is improved, but the latency requirement cannot be met due to transmission interruptions

Engineering Contradiction:
Improvedata transmission speedVSAvoidtransmission latency
Core Design Contradiction:
SpeedVSLoss of time

Solution Approach 1:

The patent divides each dataset into two sub-datasets (first and second sub-datasets) with different bandwidth requirements. The first sub-dataset is transmitted using a low-bandwidth signal that can complete transmission within a single scheduling time slot, ensuring low latency. The second sub-dataset is transmitted using a high-bandwidth signal that can be completed in the earliest available scheduling time slot. This segmentation allows the system to meet latency requirements while efficiently utilizing available bandwidth resources.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If transmission periods are used with long duration, then resource allocation is simplified, but latency requirements cannot be met

Engineering Contradiction:
Improvetransmission scheduling complexityVSAvoidtransmission latency
Core Design Contradiction:
Device complexityVSLoss of time

Solution Approach 1:

The patent segments each transmission period into multiple scheduling time slots of equal duration. This segmentation allows the system to allocate resources efficiently while ensuring that transmissions can be completed within the required latency bounds. By dividing the transmission period into smaller slots, the system can schedule transmissions more precisely without significantly increasing overall complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs dynamic scheduling where the transmitter adapts the bandwidth and timing of transmissions based on the specific requirements of each sub-dataset. The system dynamically selects whether to use low-bandwidth or high-bandwidth transmission modes depending on the data priority and latency requirements, allowing flexible resource allocation that meets both simplicity and performance requirements.

Inventive Principle:
Principle #15Dynamics

3Productivity

If high bandwidth is used for all transmissions, then data transmission efficiency is improved, but power consumption increases

Engineering Contradiction:
Improvedata transmission efficiencyVSAvoidpower amplifier consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent applies different bandwidth qualities to different parts of the data transmission process. The first sub-dataset, which has strict latency requirements, is transmitted using low-bandwidth signals that consume less power. The second sub-dataset, which can tolerate some delay, is transmitted using high-bandwidth signals that provide higher transmission efficiency. This local differentiation of transmission quality allows the system to optimize both power consumption and transmission efficiency for different data priorities.

Inventive Principle:
Principle #3Local quality
