Solution Overview

Problem

Zero power terminals struggle to determine the appropriate channel for signal reception and transmission after obtaining power, leading to inefficiencies in power consumption and complexity when multiple channels are deployed by the network.

Innovation Solution

The terminal device determines a first channel for signal reception and a second channel for signal transmission, using predefined rules and shifting amounts to align with network device channels, reducing the need to monitor or transmit on all channels, thereby saving power and simplifying operations.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the terminal device monitors all channels to ensure signal reception, then communication reliability is improved, but power consumption increases

Engineering Contradiction:
Improvesignal reception reliabilityVSAvoidterminal device power consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent divides the communication channels into multiple segments and assigns specific channels for downlink signal reception and uplink signal transmission. Instead of monitoring all channels, the terminal device only needs to monitor the specific downlink channel assigned to it, thereby reducing power consumption while maintaining reliable signal reception.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the terminal device transmits signals on all channels to ensure communication coverage, then communication reliability is improved, but device complexity increases

Engineering Contradiction:
Improvecommunication coverageVSAvoidterminal device working complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent segments the communication channels and assigns specific roles to each channel. The terminal device only needs to transmit signals on the specific uplink channel assigned to it, rather than managing all channels, which significantly reduces the device's working complexity while ensuring reliable communication coverage.

Inventive Principle:
Principle #1Segmentation

3Adaptability or versatility

If the terminal device monitors multiple channels to determine the appropriate channel, then adaptability is improved, but power consumption increases

Engineering Contradiction:
Improvechannel selection capabilityVSAvoidterminal device power consumption
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent implements preliminary channel assignment where the network device pre-configures specific downlink and uplink channels for the terminal device. This preliminary action eliminates the need for the terminal device to monitor and determine channels dynamically, reducing power consumption while maintaining adaptability through pre-optimized channel selection.

Inventive Principle:
Principle #10Preliminary action

4Reliability

If the terminal device transmits on multiple channels to ensure network coverage, then communication reliability is improved, but power consumption increases

Engineering Contradiction:
Improvenetwork communication reliabilityVSAvoidterminal device power consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The patent segments communication functions into specific channels, with dedicated downlink channels for signal reception and uplink channels for signal transmission. The terminal device only transmits on its assigned uplink channel, reducing power consumption while maintaining network communication reliability through proper channel segmentation and assignment.

Inventive Principle:
Principle #1Segmentation
