Solution Overview

Problem

The increasing demand for high data throughput and diverse communication services in wireless communication systems, particularly in 5G networks, necessitates a method to efficiently utilize limited radio resources and manage latency and reliability, especially for high-density nodes and user equipment (UEs).

Innovation Solution

A semantic-based approach is introduced, where data is decomposed into semantic element values, allowing for selective first transmission and retransmission based on reception requests, utilizing a semantic decomposition and composition layer to optimize communication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If data is transmitted using traditional methods in high-density wireless communication systems, then the volume of data throughput increases, but radio resource efficiency deteriorates and latency increases

Engineering Contradiction:

Improvedata throughputVSAvoidradio resource efficiency

Core Design Contradiction:

ProductivityVSLoss of energy

Solution Approach 1:

The transmitting device decomposes data into multiple semantic elements before transmission. Each semantic element represents a meaningful component of the original data, allowing selective transmission based on importance and receiver needs. This segmentation enables efficient use of radio resources by transmitting only necessary semantic elements rather than entire data sets.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention extracts essential semantic elements from the original data and transmits only those elements that are most valuable or requested by the receiver. This extraction process removes redundant information, improving radio resource efficiency while maintaining the core meaning and utility of the transmitted data.

Inventive Principle:

Principle #2Taking out (Extraction)

2Reliability

If all semantic element values are transmitted in the first transmission, then data completeness is improved, but transmission time and latency increase

Engineering Contradiction:

Improvedata completenessVSAvoidtransmission latency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The transmitting device performs partial transmission by sending only some semantic element values in the first transmission, rather than all elements. The receiver requests specific elements that are most needed, and the transmitter sends only those requested elements in subsequent transmissions. This partial action approach reduces initial transmission latency while ensuring data completeness through on-demand retrieval.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The transmitting device performs preliminary decomposition of data into semantic elements before transmission. This preliminary action organizes the data structure in advance, enabling selective and efficient transmission of specific elements based on receiver requests, thereby reducing overall transmission time while maintaining completeness.

Inventive Principle:

Principle #10Preliminary action

3Loss of energy

If selective retransmission of semantic element values is performed, then radio resource efficiency is improved, but system complexity increases

Engineering Contradiction:

Improveradio resource efficiencyVSAvoidcommunication system complexity

Core Design Contradiction:

Loss of energyVSDevice complexity

Solution Approach 1:

The receiving device sends requests to the transmitting device indicating which semantic element values are needed. This feedback mechanism enables selective retransmission, where only the specific requested elements are sent in subsequent transmissions. The feedback loop optimizes radio resource usage by avoiding transmission of already-received or non-essential elements, while the added complexity is managed through standardized request-response protocols.

Inventive Principle:

Principle #23Feedback

4Reliability

If traditional retransmission methods are used, then data reliability is maintained, but latency and resource consumption increase

Engineering Contradiction:

Improvedata transmission reliabilityVSAvoidretransmission latency

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Instead of retransmitting entire data sets or fixed blocks, the invention extracts and transmits only the specific semantic element values that are missing or requested by the receiver. This targeted extraction approach maintains data reliability by ensuring all necessary elements are eventually received, while significantly reducing retransmission latency compared to traditional methods.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

A sender may: decompose, on the basis of a plurality of semantic elements, data into semantic element values respectively corresponding to the plurality of semantic elements; perform a first transmission including some semantic element values from among the semantic element values; and on the basis of receiving a retransmission request for the first transmission from a receiver, perform a retransmission including at least one semantic element value other than the semantic element values included in the first transmission, from among the plurality of semantic element values.
