Wireless Signal Pre-Indication for Low-Power Multi-Mode Reception
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems face challenges in efficiently receiving signals due to limited signal generation modes and resource positioning, particularly in scenarios requiring low power consumption, small size, and low cost, such as harsh environments and wearable devices.
Innovation Solution
A wireless communication method where a transmitting device sends a first signal indicating the signal generation mode and resource position information, allowing the receiving device to adapt its reception accordingly, utilizing zero-power communication technologies like back scattering and power harvesting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a transmitting device selects from multiple signal generation modes to generate signals, then signal transmission flexibility and adaptability are improved, but receiving device complexity increases due to the need to handle multiple modes
Solution Approach 1:
The transmitting device performs preliminary action by sending indication information about the signal generation mode and resource position before the actual target signal transmission. This allows the receiving device to prepare appropriate reception parameters in advance, simplifying its design as it doesn't need to continuously monitor and decode multiple possible signal formats, but only needs to configure itself based on the pre-provided indication information.
2Productivity
If indication information includes both signal generation mode and resource position information, then communication efficiency is improved, but signal transmission overhead increases
Solution Approach 1:
The patent merges signal generation mode indication and resource position information into a single indication information package transmitted from the transmitting device. This combining approach improves communication efficiency by providing both critical pieces of information together in one transmission event, rather than requiring separate signaling for each parameter, thereby reducing the total number of signaling operations needed.
3Adaptability or versatility
If receiving devices must support multiple signal generation modes, then system versatility is improved, but power consumption increases
Solution Approach 1:
By receiving indication information in advance that specifies the exact signal generation mode and resource position to be used, the receiving device can configure its reception parameters specifically for that mode rather than maintaining continuous readiness for multiple modes. This preliminary configuration approach reduces power consumption by allowing the device to enter lower-power states for unsupported modes while maintaining full functionality only for the indicated mode.

AI summary
A wireless communication method includes: transmitting, by a transmitting device, a first signal to a receiving device, where the first signal is used to indicate a signal generation mode and/or resource position information of a target signal, and the target signal is a signal transmitted from the transmitting device to the receiving device.
