Network Planning TRIZ Cases
- PCI Selection Using Radio Environment Maps
A method selects optimal Physical Cell Identifiers using radio environment maps and hierarchical block structures.
- Radio White Space Database Discovery for Multi-Region Frequency Access
An intermediary server resolves device complexity by routing location queries to regional databases, enabling seamless multi-region frequency access.
- Relay Node Donor Selection via Frequency Separation
A relay node selects donor access nodes using frequency separation thresholds to minimize backhaul interference.
- Extending Unlicensed Spectrum Coverage with Distributed Remote Radio Heads
Segmented remote radio heads allocate unlicensed channels based on local activity reports to resolve coverage mismatches in carrier aggregation.
- Asymmetric Dynamic Spectrum Sharing for LTE-NR Capacity
Asymmetric dynamic spectrum sharing allocates unequal spectrum portions to LTE and NR, reducing control channel overhead and increasing NR PDCCH capacity.
- Spectrum Management Entity Proxy for Inter-Frequency Mobility
A spectrum management entity proxy generates neighbor channel lists to configure user equipment for inter-frequency measurements.
- RAN Node Coordination for Unlicensed Spectrum Load Metrics
Radio access nodes exchange load metrics and listen-before-talk configurations to resolve suboptimal energy detection thresholds in unlicensed spectrum.
- TDD Frame Alignment for Multi-Technology Wireless Coexistence
Aligning idle periods in TDD frames prevents interference between different wireless access technologies, reducing infrastructure investment costs.
- Mobile Wi-Fi Channel Synchronization for Stability
Coordinated channel switching prevents independent transitions that degrade throughput and stability in mobile Wi-Fi networks.
- Cell Placement Optimization Using Ray-Tracing Channel Matrices
A cell placement method generates ray-tracing channel matrices to calculate fitness values for candidate locations.
- Frequency Control Device Subchannelization for IoT Spectrum
A control device divides frequency bands into subchannels based on node capabilities and measurement results.
- Cell Site Parameter Adjustment via Map-Based Antenna Position Correction
A parameter optimization tool corrects antenna location coordinates by moving display elements on a map to their actual positions.
- Terminal Search Space Configuration for 5G Dynamic Spectrum Sharing
A terminal control unit configures search space set groups to receive downlink control channels from secondary cells.
- Adaptive Backoff Control for Multi-Beam Channel Listening
Historical backoff values guide parameter selection for directional beams, resolving inefficiencies caused by random contention in unlicensed frequency bands.
- Wireless Bonded Channel CCA Mechanism for Interference Reduction
A wireless station detects CF-End packets to determine secondary channel availability during bonded transmission sequences.
- Cognitive Radio Coexistence via Secondary User Database
Secondary user databases merge sensing data from multiple radios to resolve spectrum efficiency trade-offs caused by passive detection errors.
