Baseband System Details TRIZ Cases
- CORESET Precoder Granularity for Multi-UE Control Scheduling
A configurable CORESET precoder granularity improves channel estimation for reduced-capability UEs while enabling efficient multi-UE scheduling.
- OFDMA Uplink Control Mapping Around DMRS for Reliable UCI
Dynamic UCI resource-element mapping around DMRS improves frequency diversity and channel estimation in OFDMA uplink multiplexing.
- Interleaved Pilot Sequences for Orthogonal Channel Estimation
Interleaved orthogonal pilot symbols preserve channel estimation accuracy when transmitter and receiver run at different clock rates.
- Differential Channel Termination for Dual-Mode Impedance Matching
A matched termination circuit lets one differential channel carry data and clock via differential and common modes, improving signal integrity without PLLs.
- SRS Resource Indicators for 8-Antenna Uplink Configuration
Segmented SRS resource indicators configure 8 uplink antenna ports with lower signaling overhead while preserving transmission accuracy and battery efficiency.
- Uplink Precoding Matrix Indication via Downlink Equivalent Channel
Downlink reference signal channel estimation enables more precise uplink precoding matrix indication without adding resource overhead.
- Multi-Receiver Timing Alignment for Shorter FIR Signal Synthesis
Arrival-time alignment across multiple wave receivers cuts FIR tap length, lowering computation while preserving BER and convergence.
- OTFS Receiver Using Superimposed Pilots for Doppler Spread
Superimposed pilots and iterative KL-BEM estimation improve OTFS channel tracking under Doppler spread while preserving spectral efficiency.
- PRS Frequency Overlap Scheduling for Phase Compensation
Partial frequency overlap between staggered PRS resources enables phase estimation across time intervals, improving positioning accuracy and spectral efficiency.
- PLC Grid Topology Detection Using CIR Variation and Token Checks
CIR variation between PLC nodes pinpoints added or removed grid connections, while token exchange confirms topology changes under noisy conditions.
- Sidelink Precoding Using SVD for TDD MIMO Coverage
SVD-based channel estimation selects right singular vectors for PSSCH precoding, improving TDD sidelink throughput and coverage.
- Score-Based Channel Estimation for High-Dimensional MIMO
A score-based generative model refines pilot-aided channel estimates for high-dimensional MIMO, improving new-environment robustness and pilot efficiency.
- PUSCH Control Multiplexing with RS-Adaptive UCI Placement
Critical UCI is placed next to reference signals on PUSCH to improve channel estimation, protect ACK/RI/CQI, and keep PAPR low.
