Pilot Signal Allocation TRIZ Cases
- Optical IQ Modulator Phase Control via Pilot Tone Extraction
A control unit generates single sideband pilot signals to monitor and adjust the phase difference between Mach-Zehnder modulator outputs.
- DMRS Port Configuration via Extended CDM Groups
Terminal controls demodulation reference signal transmission using extended code division multiplexing group associations.
- Flexible SRS Triggering via Dynamic Timing Offsets
Terminal controls sounding reference signal transmission using multiple resource sets and dynamic timing offsets to resolve rigid triggering bottlenecks.
- Terminal Beam Tracking via Dual Report Information
A terminal apparatus reports first and second report information to a base station for downlink user data and beam tracking.
- Sidelink PRS Resource Pool Segmentation for Positioning Accuracy
Configuring dedicated sidelink positioning reference signal resource pools to optimize frequency allocation and minimize interference.
- Flexible Aperiodic SRS Triggering via Dynamic Offset Selection
Reduces DCI overhead and enhances triggering flexibility by selecting from pre-configured offset values rather than transmitting full timing information.
- 2-Step Random Access Resource Validation in 5G Uplink
Resolves uplink-downlink conflicts by validating random access resources before transmission, improving procedure performance.
- Dynamic Random Access Channel Resource Allocation in CBRA
Terminal identifies unconfigured random access channel occasion sets to reduce contention and improve utilization efficiency.
- Uplink Channel Repeated Transmission Spatial Diversity
Repeatedly transmitting uplink channels across multiple resource units resolves mapping ambiguity during dropping events to maximize spatial diversity gain.
- Dynamic Coreset Pool Index Interchange for 5G Uplink
Terminal devices interchange coreset pool indices with sounding reference signal resource sets to adjust physical uplink shared channel transmissions.
