Wireless Device Uplink Coordination for Overlapping Media
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high demand for radio resources in wireless networks due to simultaneous transmission of large amounts of media content from multiple devices, such as cameras, exceeds the available uplink capacity, leading to inefficient use of spectral resources and interference.
Innovation Solution
A method for coordinating uplink transmissions among multiple wireless communications devices, such as cameras, by determining overlapping content and sending coordination messages to refrain from transmitting unnecessary data, thereby optimizing spectral resource utilization and reducing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple wireless communication devices transmit large amounts of media content simultaneously, then the media production capability is improved, but the uplink capacity and spectral resource efficiency deteriorate
Solution Approach 1:
The patent merges the functionality of multiple wireless communication devices into a single coordinated transmission system. A coordinating device receives media content from multiple devices, determines overlapping content, and manages unified transmission, thereby reducing total uplink traffic while maintaining media production capability.
Solution Approach 2:
The patent extracts and removes redundant overlapping media content from transmissions. The coordinating device identifies duplicate content across multiple devices and eliminates it before transmission, reducing the quantity of data requiring uplink capacity while preserving essential media information.
2Adaptability or versatility
If multiple wireless communication devices transmit overlapping media content, then the media coverage is improved, but the spectral resource utilization deteriorates
Solution Approach 1:
The patent combines media content from multiple devices at a coordinating device, merging duplicate overlapping content into a single transmission stream. This maintains comprehensive media coverage while eliminating redundant spectral resource consumption from duplicate transmissions.
Solution Approach 2:
The patent discards redundant overlapping media content that would be transmitted multiple times by different devices. The coordinating device identifies and removes these duplicates, recovering spectral resources that would otherwise be wasted on redundant transmissions while preserving unique media content.
3Loss of information
If all wireless communication devices transmit their media data, then the data completeness is improved, but the interference and energy consumption deteriorate
Solution Approach 1:
The patent introduces a coordinating device as an intermediary between multiple media-capturing devices and the network. This intermediary consolidates transmissions, determining which devices should transmit based on content uniqueness, thereby reducing interference while maintaining data completeness through coordinated full coverage.
