Solution Overview

Problem

Current wireless communication networks face challenges in achieving low latency and optimal bandwidth utilization, particularly in legacy systems like IEEE802.11 and GSM, where the existing signaling methodologies are not efficient in utilizing degrees of freedom for improved performance.

Innovation Solution

The introduction of a method where a transmitting node uses a shift in signal characteristics to indicate additional information bits, allowing for enhanced latency and bandwidth utilization by mapping these bits to code matrices and transmitting them alongside the payload, enabling robust transmission even in stationary or slowly varying channels.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional signaling methodologies are used in legacy wireless systems, then system compatibility is maintained, but bandwidth utilization and latency performance deteriorate

Engineering Contradiction:
Improvebandwidth utilizationVSAvoidsignaling complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges payload data transmission with signaling information transmission by embedding additional information bits within the payload burst itself. This combining approach allows the system to maintain legacy compatibility while improving bandwidth utilization, as the same transmission medium carries both data and control information simultaneously rather than requiring separate signaling channels

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent makes the payload burst serve multiple functions: it carries both the primary payload data and additional signaling information bits. This multi-functionality allows legacy systems to benefit from improved performance without requiring separate dedicated signaling resources, effectively making the payload transmission universal for both data and control purposes

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Loss of information

If additional signaling channels are introduced to improve performance, then information transmission capability is enhanced, but system complexity and overhead increase

Engineering Contradiction:
Improveinformation transmission capabilityVSAvoidsystem overhead
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The patent combines multiple information streams (payload data and additional signaling bits) into a single transmission burst. This merging eliminates the need for separate signaling channels and their associated overhead, while still providing enhanced information transmission capability through the unified burst structure

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The payload burst is designed to serve dual purposes: transmitting both data payload and control signaling information. This multi-functionality reduces system overhead by eliminating dedicated signaling resources while maintaining enhanced information transmission capabilities through the versatile burst format

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Productivity

If legacy signaling methods are used, then system compatibility is maintained, but latency and performance deteriorate

Engineering Contradiction:
Improvelatency performanceVSAvoidsystem compatibility
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality by making the additional information bits optional and targeted specifically at first receiving nodes that can utilize them. Legacy receiving nodes continue to process only the standard payload without being affected by the additional bits, thus maintaining compatibility while improving performance for capable nodes

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

Instead of adding separate signaling channels that would increase overhead, the patent inverts the approach by embedding signaling information within the existing payload structure. This inversion allows legacy systems to ignore the additional bits and maintain compatibility, while advanced systems can extract and utilize them for improved latency performance

Inventive Principle:
Principle #13The other way round (Inversion)

AI summary

Embodiments herein relate to a method performed in a transmitting node (12) for transmitting at least one burst of energy to one or more receiving nodes (10,13) in a wireless communication network (1). The transmitting node (12) comprises a number of transmit antennas being more than one and wherein the at least one burst of energy carries a payload for one or more receiving nodes (10,13). The transmitting node (12) determines a shift, for one or more transmit antennas, in one or more signal characteristics of a burst of energy of the at least one burst of energy. The shift indicates one or more additional information bits, in addition to the payload, for a first receiving node (10). The transmitting node further transmits, over the one or more transmit antennas, the burst of energy of the at least one burst of energy with the shift in the signal characteristic carrying the payload to one or more receiving nodes (10,13) in the wireless communication network (1).
