Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G New Radio (NR) systems, terminals face challenges in efficiently reporting and managing antenna switching capabilities to network devices, which affects the network's ability to adapt transmission requirements effectively.
Innovation Solution
A method where terminals report antenna switching capability information to network devices, indicating their ability to switch between antennas or antenna ports, allowing the network to perform scheduling and initiate necessary antenna or antenna port switching based on this information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the terminal reports antenna switching capability information to the network device, then the network can efficiently schedule and implement antenna switching to meet transmission requirements, but the complexity of capability information management and reporting increases
Solution Approach 1:
The antenna switching capability information is segmented into different types (first antenna switching capability information and second antenna switching capability information), each representing different switching scenarios. This segmentation allows the network to manage capability information in an organized manner and selectively apply the appropriate capability information based on specific transmission requirements, thereby improving switching efficiency without overwhelming complexity in capability management.
2Adaptability or versatility
If the terminal supports switching between multiple antennas or antenna ports, then the adaptability to different transmission requirements improves, but the device complexity increases
Solution Approach 1:
The patent introduces dynamic capability information reporting where the terminal reports different antenna switching capability information based on the current BWP configuration and transmission requirements. The network device dynamically determines which capability information to use based on the actual transmission scenario, enabling the system to adapt to different transmission requirements while managing complexity through dynamic rather than static configuration.
3Reliability
If the network performs scheduling based on reported antenna switching capability information, then the transmission performance improves, but the time required for capability reporting and scheduling increases
Solution Approach 1:
The terminal reports antenna switching capability information in advance before the actual transmission occurs. This preliminary action allows the network device to prepare scheduling decisions ahead of time, reducing the time required during actual transmission scheduling. The capability information is made available beforehand, enabling the network to efficiently match transmission requirements with appropriate antenna configurations without last-minute delays.
