Solution Overview

Problem

Existing wireless communication systems use suboptimal energy detection thresholds (EDT) for narrowband (NB) devices operating in 5 and 6 GHz frequencies, leading to reduced transmission opportunities and increased interference.

Innovation Solution

Dynamically determine the EDT as a function of instantaneous transmission power and a defined value, allowing NB devices to adjust their transmission power based on environmental conditions and network usage, thereby optimizing transmission opportunities and reducing interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If fixed energy detection thresholds are used for NB devices, then device complexity is reduced, but transmission opportunities are reduced and interference increases

Engineering Contradiction:

Improvetransmission opportunitiesVSAvoidEDT determination complexity

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The patent implements dynamic EDT adjustment by making the energy detection threshold a function of instantaneous transmission power. Instead of using a fixed EDT value, the system continuously adapts the EDT based on current transmission conditions, allowing NB devices to seize more transmission opportunities while maintaining appropriate interference levels through power-dependent threshold adjustment.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent changes the parameter of EDT from a fixed value to a variable determined by instantaneous transmission power. By establishing EDT as a function of transmission power parameters, the system optimizes channel access decisions dynamically, improving transmission productivity without requiring complex multi-factor analysis.

2Reliability

If higher transmission power is used by NB devices, then transmission reliability is improved, but interference to other devices increases

Engineering Contradiction:

Core Design Contradiction:

ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent implements a feedback mechanism where the EDT is determined based on instantaneous transmission power, creating a closed-loop system. The device monitors its own transmission power and adjusts the EDT accordingly, allowing it to maintain reliable transmissions at appropriate power levels while automatically reducing interference potential through power-dependent threshold adaptation.

AI summary

Systems and methods for optimized energy detection thresholds may include a first device which determines an instantaneous transmission power for a packet to be transmitted by the first device to a second device via a narrowband (NB) communication link. The first device may determine an energy detection threshold (EDT), as a function of the instantaneous transmission power for the packet and a defined value. The first device may transmit, to the second device, the packet according to the EDT via the NB communication link.
