Duplex Signal Operation TRIZ Cases
- Full Duplex Resource Fallback for Wireless Traffic Adaptation
User equipment detects full duplex time resources and receives fallback operation information to perform adaptive switching between full duplex and TDD modes.
- RF FPFA Transceiver Circuit Reconfiguration for Multi-Standard Flexibility
A radio frequency field programmable function array reconfigures transceiver blocks to support multiple wireless standards.
- Intermodulation Interference Handling in Wireless Network Nodes
Network node schedules uplink grants within specific time intervals to manage interference.
- Transceiver Bypassing Diplexer to Trap Desensitizing Frequencies
Hardware bypasses a diplexer in normal operation and traps desensitizing frequencies during carrier aggregation, preventing receiver interference.
- TDD Network Resource Management via Overlapping Base Station Zones
Overlapping base station zones allow user equipment to select optimal uplink and downlink resources, resolving pseudo congestion in TDD networks.
- Transceiver Front-End Isolation Using Frequency-Translated Impedance
Frequency-translated impedance networks in a transceiver front-end provide isolation between transmitter and receiver, reducing device complexity.
- RF Module Filter Placement for Multiband Isolation
A radio-frequency module positions a transmission-reception filter between the power amplifier and switches to reduce line lengths.
- TDD Scheduling Overhead Reduction via Slot Repetition
A wireless terminal transmits frames defining TDD service period structures and schedules for channel access.
- Distortion-Source Mixer for Full-Duplex Linearity
A distortion-source mixer models and subtracts harmonic components to improve frequency mixing linearity.
- 2-Step Random Access Msg A Transmission Method
Terminal device determines PRACH and PUSCH transmission based on slot format to avoid resource conflicts in 5G NR.
- LTE Resource Block Group Allocation Signaling
Grouping physical resource blocks reduces signaling overhead while maintaining flexibility in LTE downlink systems.
- Switching Circuit for Cellular and Wi-Fi Filter Coexistence
Segmented filters reduce in-band insertion loss and minimize receive band noise while maintaining spectral efficiency between adjacent frequency bands.
- Magnetic-Free Non-Reciprocal Circuits via Spatio-Temporal Modulation
A magnetic-free non-reciprocal circuit uses sub-harmonic spatio-temporal conductance modulation to direct signal flow without external magnets.
- Band 28 RF Duplexer Segmentation for Overlapping Band Suppression
Segmenting Band 28 into two duplexers suppresses the 703MHz-710MHz overlap, resolving data loss in stray tests.
- Hybrid Self-Interference Cancellation for Full-Duplex Transceivers
Segmenting cancellation across RF, IF, and digital stages improves spectral efficiency while managing frequency-dependent interference.
