Site Diversity TRIZ Cases
- QCL Antenna-Port Indication With Selective Parameter Dropping
Selective QCL parameter dropping addresses fixed TCI-state limits by tailoring antenna-port assumptions for high-speed movement and SFN transmission.
- RF Antenna Aggregator for Low-Cost Multi-Beam Processing
Analog preprocessing combines antenna signals before digitization, enabling multi-beam processing with fewer digitizers and lower power use.
- Secondary Base Station Configuration Retention for Lower RRC Latency
Maintaining secondary base station configuration through RRC_INACTIVE reduces reestablishment delay when returning to RRC_CONNECTED in dual connectivity.
- UE Capability Signaling for TRP-Specific Beam Failure Recovery
Capability signaling enables a UE to recover weak per-TRP beams independently, improving recovery timing and reliability.
- Closed-Form Beam Nulling for Self and Cross-Sector Interference
Iterative beam nulling can demand heavy computing and memory; a closed-form matrix transformation suppresses self and cross-sector interference.
