Site Diversity TRIZ Cases
- TDD Repeater Dynamic Direction Detection for 5G Interference
A repeater monitors signals in flexible time intervals to determine transmission direction.
- FPGA Queuing Engine for Multicasting Ethernet Data in Distributed Antenna Systems
Integrating a queuing engine into an FPGA eliminates external layer 2 switches, reducing hardware complexity while maintaining reliable Ethernet transmission.
- CBSD Antenna Beamforming for Cell Edge Interference Mitigation
Assigning at least eight antennas per device in the cell edge region creates narrow directive beams that mitigate interference and prevent SAS deallocation.
- Uplink Control Channel Codebook Design for Unlicensed Spectrum
A downlink grant indicator bit enables user equipment to determine the correct feedback report format for uplink transmission.
- MBSFN Subframe Cyclic Prefix Configuration for LTE-A Coverage
Applying local quality to MBSFN subframes by using distinct cyclic prefixes for control and data symbols, resolving throughput versus coverage trade-offs.
- Transmission Device Frame Configuration for MIMO Signal Detection
A transmission device configures frames by gathering SISO or MISO data to improve reception performance.
- Inter-Terminal Coordinated Communication via Selective Information Sharing
Terminals share specific signals to enable independent network information processing.
- Interference Covariance Calculation for CoMP Channel Quality
First communication device selects interference covariance calculation technique and transmits indication to second device.
- Terminal Paging Signal Transmission for Power Saving State
Base station transmits configuration information and reference signals to enable terminal beam reporting in a single instance.
- Channel Correction for Distributed Radio Frequency Apparatuses
Segmenting distributed radio frequency apparatuses into groups reduces configuration signaling overhead and accelerates channel correction cycles.
