Modulated-Carrier Systems TRIZ Cases
- PRS Configuration via LMF for 5G Positioning Accuracy
LMF determines PRS configuration using SSB periodicity, resolving the trade-off between positioning accuracy and system complexity in wireless networks.
- Cell-Group Slot Format Indication for Wireless Full Duplex
Cell-group slot format indication reduces signaling overhead by transmitting unified configuration to user equipment across multiple cells.
- RF Signal Path Phase Rotation Measurement via Heterodyne Mixing
A phased-array measurement system uses heterodyne mixing to detect phase rotation across multiple signal paths with high precision.
- MZI Phase Control via Local Heater Power for Wavelength Matching
A Mach-Zehnder interferometer uses local heater power to adjust phase difference between split optical signals.
- LTE PDCCH and PRS Resource Conflict Resolution
A method for transmitting positioning reference signals alongside physical downlink control channel data in LTE subframes.
- Digital Compensation for Switchable Analog Filter Echo Cancellation
A digital compensation filter adjusts frequency response during analog filter switching in full duplex cable modems.
- Sidelink DMRS Generation Using Uplink Scrambling Identifiers
A first terminal calculates a demodulation reference signal sequence using a scrambling identifier received from a base station for sidelink communication.
