Wireless Relay Configuration via Triggered TXS Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently managing transmission opportunities and relaying data between access points and stations, particularly in scenarios where multiple stations and relay stations are involved, leading to potential delays and reduced communication reliability.
Innovation Solution
The implementation of a triggered Transmission Opportunity Sharing (TXS) procedure, where an access point allocates specific time periods for transmission opportunities to stations, allowing for efficient relaying of data through designated relay stations, and indicating the type of communication (uplink or downlink) to optimize resource allocation and communication pathways.

Engineering Contradiction Analysis
1Reliability
If relay stations are used to extend communication coverage, then communication reliability is improved, but transmission latency increases
Solution Approach 1:
The access point pre-allocates transmission opportunities and time periods for relay stations before actual data transmission occurs. This preliminary resource allocation ensures that relay stations have dedicated time slots ready, reducing waiting time and latency during actual communication while maintaining reliable relayed connections.
Solution Approach 2:
The transmission opportunity is divided into multiple time periods, with specific time periods allocated to relay stations and other time periods allocated to end stations. This segmentation allows simultaneous dedicated relay transmission and direct transmission without interference, reducing overall latency while maintaining reliability.
2Productivity
If transmission opportunities are allocated to multiple stations, then network capacity is improved, but resource management complexity increases
Solution Approach 1:
The transmission opportunity is segmented into distinct time periods, with each time period dedicated to specific stations or relay stations. This time-based segmentation simplifies resource management by providing clear, non-overlapping allocation rules, reducing the complexity of managing multiple station transmissions while maintaining high network capacity.
Solution Approach 2:
The access point dynamically allocates different time periods within each transmission opportunity to different stations based on current network conditions and requirements. This dynamic allocation optimizes network capacity for varying traffic patterns while the structured time-period framework keeps management complexity manageable.

AI summary
One or more stations may communicate with an access point via one or more relay stations. The one or more stations and relay station(s) may receive an indication indicating allocated resources and a type of communication. One or more times periods, within a particular allocated resource, may be indicated for use by one or more stations to communicate with the access point using at least one relay station. Based on the indication, the one or more stations and relay station(s) may be configured to activate a relaying procedure for communication with the access point.
