1Area of stationary object
If distributed antenna systems are introduced to expand wireless network coverage, then network coverage and flexibility are improved, but the clarity of connection establishment between terminal devices and network devices deteriorates
Solution Approach 1:
The patent introduces synchronization signals as intermediary elements that mediate between distributed antenna ports and terminal devices. These signals carry antenna port indication information, enabling terminal devices to identify and connect to appropriate antenna ports in distributed antenna systems without losing connection establishment clarity.
Solution Approach 2:
The patent segments the distributed antenna system into multiple antenna ports, each transmitting synchronization signals with specific indication information. This segmentation allows terminal devices to independently identify and connect to individual antenna ports, maintaining connection clarity while supporting expanded network coverage through multiple distributed ports.
2Productivity
If distributed antenna systems are deployed to quickly build wireless networks, then network deployment speed and flexibility are improved, but the complexity of terminal device connection establishment increases
Solution Approach 1:
The patent enables terminal devices to autonomously determine antenna ports by detecting synchronization signals and extracting antenna port indication information. This self-service mechanism eliminates the need for complex centralized control during connection establishment, reducing device complexity while maintaining fast network deployment capabilities.
Solution Approach 2:
The patent incorporates antenna port indication information into synchronization signals that are transmitted before actual data communication. This preliminary action allows terminal devices to pre-identify appropriate antenna ports during the synchronization phase, simplifying subsequent connection establishment and maintaining rapid network deployment.
3Productivity
If terminal devices autonomously determine antenna ports based on synchronization signals, then connection establishment efficiency is improved, but the precision of antenna port identification must be maintained
Solution Approach 1:
The patent uses different synchronization signal sequences or patterns (analogous to color changes) to represent different antenna ports. This allows terminal devices to efficiently and precisely identify antenna ports by detecting and distinguishing these unique signal characteristics, maintaining both connection establishment efficiency and identification precision.
Solution Approach 2:
The patent implements a feedback mechanism where terminal devices detect synchronization signals, determine antenna ports based on indication information, and use the identified antenna ports for subsequent communication. The network device can verify correct identification through communication quality feedback, ensuring both efficiency and precision in antenna port identification.
