Modulated-Carrier Systems TRIZ Cases
- Multicarrier Transceiver Switching Between Wireline and Wireless Media
A transceiver switches between wireline and wireless media using discrete Fourier transform multicarrier modulation.
- PUCCH Format 3 Resource Mapping for Interference Suppression
Variable cyclic shift values and dynamic PRB allocation improve interference suppression in congested LTE networks.
- Unlicensed Band Data Transmission Extension Signal Mechanism
Extension signals occupy channels during silent periods, preventing interference from coexisting protocols and maintaining reliable data transmission.
- OFDM Transmitter Adaptive Symbol Parameters
An OFDM transmitter adjusts symbol parameters to optimize data transmission efficiency.
- Adaptive Matrix Selection for Compressive Sensing Data Compression
Machine learning dynamically selects representation and measurement matrices based on data patterns, reducing restoration errors in compressed signals.
- Per-UE Signal Fading Simulation for Air Interface Testing
Per-UE signal faders simulate time domain uplink signals using Fourier transformation to resolve equipment cost constraints.
- PPDU with AMP BKD Excitation Extension
An AMP BKD excitation extension in PPDUs reduces network congestion by allowing devices to use existing signals for excitation.
- SRS Periodic Burst Transmissions for Positioning Signaling Overhead
Configures user equipment with SRS periodic burst transmissions to reduce signaling overhead during RRC inactive mode.
- Mobile Device Mobility Measurement Optimization
A mobile device receives subframe sequence patterns to determine transmission types and adjusts reference symbol measurements accordingly.
- Joint Downlink Sidelink Positioning Capability Reporting
Unified capability reporting merges downlink and sidelink parameters to resolve the trade-off between positioning accuracy and device complexity.
