Signal Allocation TRIZ Cases
- DCI Signal Indication for Nonorthogonal Multiple Access Superposition Transmission
Redefines downlink control information formats to transmit signal indication parameters for nonorthogonal multiple access systems.
- DCI-Based TCI State Update for CORESET in NR Systems
Direct DCI indication updates TCI states for CORESETs, bypassing slow MAC-CE procedures and reducing configuration latency.
- Slot Format Configuration for IAB Link Switching
Higher layer signaling pre-configures guard periods to reduce interference during access and backhaul link switching.
- Resource Block Group Sizing in Wireless Resource Allocation
A base station signals resource block group sizes via upper layer information to enable flexible interleaving for terminals.
- DMRS-Based CSI Reporting for Wireless Overhead Reduction
User equipment updates channel state information using demodulation reference signals to enable frequent reporting without dedicated resources.
- Uplink Channel Parameter Management in NR Systems
Segmenting transmission parameters by channel type resolves the contradiction between device complexity and resource efficiency.
- User Equipment Random Access Response Reception in NR Beamforming
A user equipment configures a dedicated control resource set to receive random access responses using beam alignment.
- PTRS Antenna Port Configuration for M-TRP Wireless Systems
Mapping TCI state codepoints to PTRS antenna ports resolves signaling overhead while supporting multiple transmission reception points.
- UE Beam Pair Indication for Full Duplex Failure Recovery
User equipment detects beam failure and indicates a selected second beam pair to the base station.
- Resource Block Bundling for LTE-A Channel Estimation
Bundling resource blocks reduces feedback overhead and improves channel estimation accuracy at the cost of reduced precoding flexibility.
- PTRS Frequency Position Determination in Multi-TRP Systems
Acquiring indication information to map TCI states to distinct PTRS frequency positions, resolving resource uncertainty and phase noise tracking complexity.
- Shortened TTI Indexing for Latency Reduction in LTE
Subframe pairing indexes shortened transmission time intervals to reduce packet data latency while managing control channel overhead.
