Spatial Transmit Diversity TRIZ Cases
- Event-Triggered UE Beam Reporting for Lower Uplink Overhead
This case uses CSI-configured event triggers so UEs report beam changes when needed, reducing signaling overhead and latency.
- Multi-TRP Channel State Reporting With Indexed Beamforming Configuration
A structured TRP index maps selected transmit points to CSI reports, reducing signaling complexity while supporting precise beamforming.
- RIS-Assisted V2X Communication for Coverage Gap Reliability
Area-specific V2X policies and RIS-reflected signals support reliable data exchange where network coverage is unreliable.
- DCI Beam Activation Timing for Lower-Latency Wireless Communication
This case uses a DCI-based beam activation command and new beam ready time to reduce delay in UE-to-base-station communication.
- Terminal Encoded CSI Reporting for Lower Feedback Overhead
Parameterized encoded CSI reporting reduces feedback overhead while preserving accuracy.
- Full-Duplex Beam Precoding for Cross-Link Interference Mitigation
Separate MCS and precoding matrices help a victim UE decode downlink messages while cancelling cross-link interference.
- MMW Communication Sub-Carrier Spacing for Beam Transition Guard Time
Variable sub-carrier spacing creates guard time for MMW beam switching.
- Default Physical Cell Identification for Multi-TRP Processing
Layer 1/2 signaling selects default PCIs across TRPs, reducing ambiguity in scrambling and physical signal processing.
- Two-Step Random Access DRX Timing for Reliable Low-Power Monitoring
Coordinate DRX active time with random access responses to reduce channel monitoring power.
- Multi-TRP PUSCH Repetitions with Dynamic Precoder Signaling
This case uses multiple SRS resources and DCI-indicated TPMIs to adapt PUSCH repetitions across TRPs while limiting signaling overhead.
- NR Frame Structure for Beam-Swept Control and Grant Resources
This case uses self-contained NR intervals to sweep control information and grant resources across multiple beams.
