Solution Overview
Problem
Existing peer-to-peer (P2P) communication systems face challenges in reducing transmission delay and improving efficiency during low-latency service data transmission, particularly due to restrictions on transmission capacity and delays caused by network congestion.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If P2P communication is used to eliminate access points, then transmission efficiency is improved, but transmission delay cannot be sufficiently reduced for low-latency services
Solution Approach 1:
The patent applies preliminary action by establishing R-TWT schedules in advance that reserve specific time slots for low-latency service data transmission. The AP device pre-configures these schedules before data transmission occurs, ensuring that TDLS devices have predetermined opportunities to exchange data without waiting for network conditions or contention resolution, thereby reducing transmission delay while maintaining efficient P2P communication
2Loss of time
If R-TWT schedules are implemented to ensure low-latency transmission, then transmission delay is reduced, but transmission capacity restrictions remain
Solution Approach 1:
The patent applies dynamics by enabling flexible data exchange within the R-TWT scheduled time slots. TDLS devices can dynamically exchange data bidirectionally during their allocated slots rather than following rigid unidirectional transmission patterns. This dynamic approach allows both devices to utilize the full transmission capacity during scheduled periods, eliminating capacity restrictions while maintaining the low-latency benefits of pre-scheduled transmission windows
3Device complexity
If unidirectional data transmission is used between TDLS devices, then implementation is simplified, but transmission efficiency decreases
Solution Approach 1:
The patent applies continuity of useful action by enabling continuous bidirectional data exchange between TDLS devices within their allocated R-TWT time slots. Rather than requiring separate transmission opportunities for each direction, the system allows both devices to transmit and receive data continuously during the scheduled period, maintaining high transmission efficiency while keeping the implementation relatively simple through centralized schedule management by the AP
