Engineering Contradiction Analysis
1Reliability
If beamforming is used to overcome path loss in mmW communication, then signal transmission reliability is improved, but the complexity of beam management and switching increases
Solution Approach 1:
The synchronization slot is segmented into multiple synchronization blocks, each associated with a specific transmission beam. This segmentation allows the system to manage multiple beams independently through structured blocks, reducing the overall complexity of beam management while maintaining reliable signal transmission across different spatial directions.
Solution Approach 2:
Transmission beams are pre-configured and associated with specific synchronization blocks before actual data transmission. This preliminary setup of beam-block associations enables the system to avoid complex real-time beam switching decisions, thereby reducing management complexity while ensuring reliable communication.
2Productivity
If synchronization blocks are used for transmission, then bandwidth utilization is improved, but the need for beam switching increases transmission complexity
Solution Approach 1:
The patent merges the functions of synchronization signaling and data transmission by assigning both to the same synchronization blocks. Each synchronization block simultaneously carries synchronization information and user data/control information through the associated transmission beam, eliminating the need for separate beam switching operations and improving bandwidth utilization.
Solution Approach 2:
Synchronization blocks are designed to serve multiple functions: they carry synchronization signals, transmit user data, and convey control information, all through a single associated transmission beam. This multi-functionality reduces the need for multiple beam configurations and switching operations, thereby reducing complexity while maintaining high bandwidth utilization.
3Device complexity
If data and control information are transmitted separately, then channel resource allocation is simplified, but transmission efficiency decreases
Solution Approach 1:
Data channels and control channels are merged and transmitted together through the same synchronization blocks and associated transmission beams. This combining approach maintains relatively simple resource allocation procedures while significantly improving transmission efficiency by utilizing the same radio resources for multiple types of information.
