Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

The existing EDGE communication system suffers from high transmission latency due to data being transmitted over multiple TDMA frames, which limits effective data throughput rates and communication performance.

Innovation Solution

The method allocates communication resources across multiple carriers within a single time frame, allowing data of a radio block to be communicated and acknowledged within a reduced time period, thereby reducing latency and improving throughput.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If data is transmitted over multiple TDMA frames in the existing EDGE communication scheme, then data throughput rate is improved, but transmission latency increases

Engineering Contradiction:

Improvedata throughput rateVSAvoidtransmission latency

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent transitions from a single-carrier, multi-frame transmission approach to a multi-carrier, single-frame transmission approach. By utilizing multiple carriers (frequency dimension) simultaneously within a single TDMA frame, the system achieves both high throughput and low latency. This dimensional shift from time-based sequential transmission to frequency-based parallel transmission resolves the contradiction between throughput and latency.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

Solution Approach 2:

The patent segments the data transmission across multiple carriers within a single TDMA frame. Instead of transmitting all data sequentially over one carrier across four frames, the data is divided and transmitted in parallel across multiple carriers simultaneously within one frame, reducing overall transmission time while maintaining high throughput.

Inventive Principle:

Principle #1Segmentation

2Reliability

If data is transmitted over four TDMA frames, then complete data block transmission is achieved, but communication response time increases

Engineering Contradiction:

Improvecomplete data block transmissionVSAvoidcommunication response time

Core Design Contradiction:

ReliabilityVSDuration of action of moving object

Solution Approach 1:

The patent enables continuous data transmission across multiple carriers within a single TDMA frame, eliminating the gaps and delays associated with sequential multi-frame transmission. This continuous parallel transmission maintains reliable complete data block delivery while significantly reducing the overall communication response time.

Inventive Principle:

Principle #20Continuity of useful action

3Reliability

If acknowledgment is sent after receiving data over multiple frames, then data communication reliability is improved, but total communication time increases

Engineering Contradiction:

Improvedata communication reliabilityVSAvoidtotal communication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent performs the data transmission and acknowledgment exchange within a single TDMA frame structure. By completing both the data block transmission and the acknowledgment process within one frame rather than spanning multiple frames, the system maintains reliable communication while reducing the total communication time and minimizing latency.
