Solution Overview

Problem

The use of higher frequencies in wireless communication systems, such as millimeter waves, poses challenges related to physical properties and timing, particularly with beamforming and new waveforms, which need to be addressed to facilitate efficient data signaling.

Innovation Solution

Implementing a method and radio node for transmitting and receiving data blocks using multiple transmission sources with different parts of the data block transmitted using different transmission resources, and utilizing interlinked modulation symbols or the same transmission resource to achieve transmission diversity and low Peak-to-Average Power Ratio (PAPR) through DFT-s-OFDM waveforms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If multiple transmission sources are used for data block transmission, then transmission diversity is improved, but device complexity increases

Engineering Contradiction:
Improvetransmission diversityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The data block is segmented into multiple parts, with each part transmitted through different transmission sources. This segmentation enables transmission diversity by distributing data across multiple channels while maintaining manageable complexity at each individual transmission source.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an additional dimension of transmission by utilizing multiple transmission sources simultaneously. This multi-dimensional approach to data transmission enhances reliability through diversity without requiring each individual source to handle the entire data block, thus controlling complexity.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Use of energy by moving object

If interlinked modulation symbols are transmitted using the same transmission resource, then PAPR is reduced, but manufacturing precision requirements increase

Engineering Contradiction:
ImprovePAPRVSAvoidmapping precision
Core Design Contradiction:
Use of energy by moving objectVSManufacturing precision

Solution Approach 1:

Interlinked modulation symbols are merged and transmitted using the same transmission resource. This combining approach reduces the peak power requirements by distributing the modulation symbols across a shared resource, thereby lowering PAPR while maintaining signal integrity through proper interlinking.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent modifies the modulation parameters by creating interlinked modulation symbols with specific mathematical relationships. This parameter transformation allows the symbols to be transmitted on the same resource with reduced PAPR, as the interlinking creates a more uniform power distribution across the transmission.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If different parts of data block are transmitted using different transmission resources, then transmission reliability is improved, but loss of time increases

Engineering Contradiction:
Improvetransmission reliabilityVSAvoidtransmission time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The data block is divided into multiple parts that can be transmitted simultaneously through different transmission resources. This segmentation enables parallel transmission, improving reliability through diversity while minimizing time loss by utilizing multiple channels concurrently rather than sequentially.

Inventive Principle:
Principle #1Segmentation
