Solution Overview

Problem

Existing wireless communication technologies, such as Listen-Before-Talk (LBT) and Detect and Avoid (DAA), increase current consumption and power requirements, and decrease battery life by requiring channel sensing operations before transmissions, which can be inefficient and time-consuming.

Innovation Solution

A method that determines aggregate transmission parameters within a communication channel, allowing transmissions to proceed without channel sensing if they do not exceed a predetermined threshold level, and adjusts parameters or delays transmissions if they do, thereby avoiding channel sensing while complying with regulatory limits.

1Reliability

If channel sensing operations (LBT/DAA) are performed before transmissions, then regulatory compliance and fair coexistence are ensured, but current consumption and power requirements increase

Engineering Contradiction:

Improveregulatory complianceVSAvoidcurrent consumption

Core Design Contradiction:

ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary aggregation of transmission parameters across multiple channels and protocols before determining whether channel sensing is required. By pre-calculating the aggregate parameter and comparing it to the threshold, the system avoids performing actual channel sensing operations when not necessary, thus reducing energy consumption while ensuring regulatory compliance when needed.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

Instead of performing full channel sensing operations for every transmission, the system applies a threshold-based filter that allows transmissions to proceed without sensing when the aggregate parameter is below the threshold. This partial action approach performs channel sensing only when absolutely necessary (when threshold is exceeded), significantly reducing energy consumption while maintaining regulatory compliance for high-usage scenarios.

AI summary

In an embodiment, a method includes determining a first upcoming transmission from a device in a first communication channel during a first time window and determining a first aggregate parameter associated with transmissions of the device in the first communication channel during the first time window. In response to determining that the first aggregate parameter does not exceed the threshold parameter level, the method includes transmitting the first upcoming transmission in the first communication channel during the first time window without listening to the first communication channel.
