Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in ensuring signal reception performance, particularly in scenarios involving zero power devices and harsh environments, where traditional power sources are inadequate, and there is a need to optimize signal generation and reception modes for efficient communication.
Innovation Solution
A wireless communication method where a transmitting device sends a first signal to indicate the signal generation mode and/or resource position information, enabling the receiving device to adjust its reception accordingly, utilizing techniques such as power harvesting, back scattering communication, and low-power consumption technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the transmitting device uses multiple signal generation modes to adapt to different communication scenarios, then the adaptability and communication performance are improved, but the receiving device faces difficulty in correctly receiving and demodulating the signal
Solution Approach 1:
The transmitting device performs preliminary action by indicating the signal generation mode and resource position information before actually transmitting the target signal. This allows the receiving device to prepare appropriate reception parameters in advance, resolving the contradiction by enabling adaptability without increasing reception complexity during signal processing
Solution Approach 2:
The first signal acts as an intermediary between the transmitting device and receiving device. It carries indication information about signal generation modes and resource positions, mediating the communication between transmitter and receiver without requiring the receiving device to handle multiple signal generation complexities directly
2Area of stationary object
If the transmitting device transmits signals in harsh environments or to zero power devices, then the communication coverage is extended, but the signal reception performance deteriorates
Solution Approach 1:
The transmitting device sends indication information in advance about the signal generation mode and resource position. This preliminary action enables the receiving device to configure optimal reception parameters before the actual signal arrives, maintaining reliability even when extending coverage to harsh environments or zero power devices
Solution Approach 2:
The system changes reception parameters dynamically based on the indicated signal generation mode. By adjusting reception parameters according to the transmitted indication information, the system maintains signal reception performance across varying environmental conditions and extended coverage areas
