Terminal Self-Interference Mitigation Through Time-Segmented Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies face challenges with terminal self-interference, where signals transmitted by user terminals cause interference to their own received signals, affecting communication performance.
Innovation Solution
Obtain transmission time domain information of a user terminal experiencing self-interference and use this information to adjust transmission times to avoid or reduce interference, employing methods such as time division multiplexing and centralized control to manage network devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user terminal transmits signals continuously to maintain communication, then communication coverage and connectivity are improved, but terminal self-interference increases and communication performance deteriorates
Solution Approach 1:
The patent implements periodic time division multiplexing where the user terminal alternates between uplink transmission and downlink reception in periodic time slots. This periodic action separates the transmitting and receiving operations in time, eliminating self-interference while maintaining continuous communication coverage through coordinated network device transmissions.
2Reliability
If the user terminal transmits uplink signals to maintain connectivity, then connection reliability is improved, but self-interference to downlink signals increases and communication quality deteriorates
Solution Approach 1:
The patent segments the communication resources into distinct uplink and downlink time slots for the user terminal. By dividing the time domain into separate segments for transmission and reception, the system maintains connection reliability through continuous resource allocation while preventing uplink signals from interfering with downlink signals during their respective time periods.
3Reliability
If transmission resources are allocated to maintain communication continuity, then communication coverage is improved, but resource allocation complexity increases and system management becomes more difficult
Solution Approach 1:
The patent employs periodic time division patterns where uplink and downlink resources are allocated in repeating time cycles. This periodic resource allocation simplifies system management by establishing predictable, recurring transmission schedules that maintain communication continuity while reducing the complexity of resource coordination compared to dynamic, non-periodic allocation schemes.
