Multi-Protocol Wireless Signal Embedding for Spectrum Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face challenges in efficiently sharing spectrum space among different standards, such as Vehicle-to-Everything (V2X), Cellular-V2X (C-V2X), and Wi-Fi, due to limited bandwidth allocation and coexistence of receivers operating on disparate protocols.
Innovation Solution
The solution involves generating and communicating signals that include data configured according to multiple protocols, specifically by inserting a data set of one protocol into a signal of another protocol, allowing receivers to decode and respond appropriately, such as vacating the channel for higher-priority communications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bandwidth is allocated in chunks to particular standards, then each standard can operate reliably, but spectrum utilization efficiency deteriorates due to limited use by other standards
Solution Approach 1:
The patent applies universality by enabling a single communication signal to serve multiple protocol standards simultaneously. The transmitting device embeds both Wi-Fi protocol data and C-V2X protocol data within the same signal structure, allowing the signal to be universally decoded by receivers of either standard, thereby improving spectrum utilization while maintaining reliable operation for both protocols
Solution Approach 2:
The patent merges data from different protocol standards (Wi-Fi and C-V2X) into a unified signal transmission framework. By combining the data sets of different protocols into a single transmitted signal, the system achieves efficient spectrum sharing while ensuring that receivers operating on different protocols can all access and process their respective protocol data
2Productivity
If multiple protocols share a common channel, then spectrum efficiency improves, but signal complexity increases making detection and decoding more difficult
Solution Approach 1:
The patent applies segmentation by dividing the common channel signal into distinct protocol-specific data segments. The transmitting device structures the signal to contain separately identifiable Wi-Fi protocol data and C-V2X protocol data portions, allowing receivers to segment and process only their protocol of interest, thereby reducing decoding complexity while maintaining efficient spectrum sharing
Solution Approach 2:
The patent uses an intermediary signal structure that mediates between different protocol requirements. The transmitted signal acts as an intermediary containing embedded data sets that can be interpreted by multiple protocol standards, facilitating smooth interaction between Wi-Fi and C-V2X receivers without requiring complex cross-protocol decoding
3Quantity of substance
If different standards attempt to utilize common channels, then available bandwidth increases, but coexistence challenges increase due to protocol disparities
Solution Approach 1:
The patent enhances protocol coexistence capability by creating a universal signal format that can be successfully received and processed by both Wi-Fi and C-V2X standards. This multi-functional signal structure allows different protocol standards to coexist harmoniously on the same channel, effectively increasing the usable bandwidth for both standards simultaneously
