Relay Device Wireless Communication Identity Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless networks with ad-hoc configurations, devices that are out of transmission range cannot communicate directly, leading to inefficient relay operations where all transmissions are forwarded, even when not necessary, due to the complexity of determining which transmissions require relaying.
Innovation Solution
A system comprising a first transmit device and a relay device that records and appends source and destination identities to data transmissions, allowing the relay device to identify pairs of devices that cannot communicate directly and forward transmissions only when necessary, based on reports from other devices.

1Area of stationary object
If a relay device forwards all transmissions it receives, then communication coverage is improved, but redundant transmissions occur and network efficiency deteriorates
Solution Approach 1:
The relay device monitors transmissions and uses feedback information (detected transmissions and their destinations) to intelligently decide whether to forward each transmission. This feedback mechanism allows the relay to avoid forwarding redundant transmissions while maintaining extended communication coverage for devices out of direct range.
Solution Approach 2:
The relay device autonomously determines which transmissions require forwarding by analyzing the feedback information itself, without requiring complex external configuration or analysis of radio channels and device capabilities. The system self-adapts to changing network conditions dynamically.
2Productivity
If the relay device determines which transmissions require relaying through analysis of radio channels and device capabilities, then forwarding efficiency is improved, but device complexity and configuration requirements increase
Solution Approach 1:
The relay device uses simple feedback information (source and destination identities of detected transmissions) to autonomously determine which transmissions need forwarding. This approach avoids complex analysis of radio channels and device capabilities, eliminating the need for complicated configuration while maintaining high forwarding efficiency.
Solution Approach 2:
Instead of analyzing complex radio channel parameters and device capabilities, the system changes to using simple identity-based feedback parameters (source and destination identities). This parameter simplification dramatically reduces device complexity and configuration requirements while preserving forwarding efficiency.
3Ease of operation
If the relay device forwards transmissions without selective filtering, then implementation simplicity is improved, but network traffic overhead increases
Solution Approach 1:
The relay device uses feedback information containing source and destination identities to selectively filter transmissions. This maintains implementation simplicity by avoiding complex analysis while reducing network traffic overhead by not forwarding transmissions that don't require relaying.

AI summary
A first transmit device (200), a relay device (202) and methods therein, for supporting wireless communication between transmit devices over a shared radio resource in a wireless network. The first transmit device (200) records (2:1B) source identities and destination identities of detected transmissions of data made by other transmit devices (204). When an own transmission of data is performed, the first transmit device (200) appends (2:2A) a report indicating the source identity and the destination identity of each detected transmission of data. By receiving (2:2B) transmissions of data with such appended reports from various transmit devices (200, 204), the relay device (202) is able to identify (2:3) two transmit devices (204A, 204B) that are not able to communicate directly with each other, and to forward (2:5) any transmission(s) (2:4) of data between the two identified transmit devices.
