R-TWT Channel Occupancy Control for Reliable Wireless Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems face inefficiencies in managing latency-sensitive traffic due to inefficient resource allocation and increased latency, particularly in environments with multiple devices competing for access to wireless channels.
Innovation Solution
Implementing a restricted target wake time (R-TWT) protocol that prioritizes transmission and reception times for latency-sensitive traffic by granting membership to devices based on beacon signals, allowing efficient resource utilization and reducing inefficiencies through adaptive scheduling of sub-service periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If R-TWT operation is performed without considering channel occupancy time, then device complexity is reduced, but communication reliability deteriorates due to insufficient time for signal transmission and reception
Solution Approach 1:
The patent introduces channel occupancy time as a new parameter to the R-TWT operation control mechanism. By adjusting this time parameter based on signal transmission requirements, the system achieves reliable communication while maintaining simplified operation control. The channel occupancy time is dynamically determined based on signal characteristics without requiring complex multi-parameter coordination.
2Reliability
If channel occupancy time is extended to ensure reliable communication, then communication reliability is improved, but energy consumption increases due to prolonged transmission and reception periods
Solution Approach 1:
The patent applies partial action by determining channel occupancy time based only on the necessary signal transmission requirements rather than using excessive time. The system calculates the minimum adequate occupancy time needed for reliable communication, avoiding unnecessary energy consumption while ensuring communication reliability is achieved through optimized rather than maximized time allocation.
3Ease of operation
If R-TWT operation does not account for signal transmission time, then operation simplicity is maintained, but communication quality deteriorates due to premature termination of transmission
Solution Approach 1:
The patent implements preliminary action by pre-determining the channel occupancy time based on signal transmission characteristics before the actual communication begins. This advance calculation ensures that sufficient time is allocated for complete signal transmission and reception, preventing premature termination while maintaining simple operation control through a straightforward time-based mechanism.
