Baseband System Details TRIZ Cases
- Receiver Channel Estimation Using Partial Reference Signals
Partial reference-signal processing lets the receiver estimate the channel sooner, cutting demodulation latency, power use, and memory demand.
- Channel State Information via Doppler-Multiplexed Pilot Signals
Orthogonal Doppler-basis pilot multiplexing lets multiple antenna-port reference signals share one time-frequency resource while preserving CSI accuracy.
- DMRS Sequence Offset Mapping for Partial-Bandwidth NR Scheduling
A signaled DMRS sequence offset lets NR terminals detect the mapped reference signal portion without knowing system bandwidth or allocation position.
- Sparse Micro-Doppler Reconstruction from Irregular Channel Measurements
Reconstructs micro-Doppler spectra from sparse, irregular channel measurements to support human activity recognition with far lower sensing overhead.
- ML Channel Feedback Interoperability for Accurate CSI Reporting
Machine learning compresses channel feedback while model and capability exchange preserves interoperability and reporting accuracy.
- Narrowband TDD Frame Structure With Dynamic Subframe Switching
Dynamic subframe configurations adapt narrowband TDD transmissions to channel conditions, improving coverage and reception reliability in challenging locations.
- UE Phase Capability Reporting for Coherent SRS Stitching
UE phase-capability reports let networks stitch SRS resources coherently across carriers, expanding positioning bandwidth and improving location accuracy.
- CSI-RS Sub-Band Selection for Intermittent Unlicensed Availability
Intermittent sub-band access can limit CSI-RS transmission; usage indications let UEs process valid sub-bands for adaptable NR communication.
- Uplink Data Scheduling Using PUSCH DMRS Channel Estimates
Periodic SRS transmissions add overhead and delay; using DMRS on scheduled PUSCH supports channel estimation for faster uplink scheduling.
