Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If antenna ports are always activated to ensure reliable data transmission, then transmission reliability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic antenna port management where the terminal can activate or deactivate antenna ports based on real-time communication conditions. The base station configures multiple antenna ports and dynamically indicates which ports should be activated through downlink control information, allowing the system to adapt antenna usage to current transmission needs rather than maintaining all ports in a static active state.
Solution Approach 2:
The system changes the operational state parameter of antenna ports between active and inactive states. The base station configures antenna port parameters including activation status, and can dynamically adjust these parameters based on channel conditions, transmission requirements, and power saving considerations, thereby optimizing the balance between reliability and power consumption.
2Reliability
If multiple antenna ports are activated to improve data transmission quality, then transmission quality is improved, but device complexity increases
Solution Approach 1:
The system implements feedback mechanisms where the terminal reports its antenna port capabilities and activation status to the base station. The base station uses this feedback information to configure and manage antenna ports appropriately, creating a closed-loop control system that reduces complexity by making management decisions based on actual terminal capabilities and current conditions rather than using fixed complex configurations.
Solution Approach 2:
The patent segments the antenna port management into distinct functional parts: capability reporting by the terminal, configuration by the base station, and dynamic activation control through downlink control information. This segmentation allows each component to handle specific aspects of antenna management independently, reducing overall system complexity while maintaining transmission quality.
3Use of energy by moving object
If antenna ports are deactivated to reduce power consumption, then power efficiency is improved, but transmission distance decreases
Solution Approach 1:
The base station performs preliminary configuration of antenna ports including capability assessment and activation settings before actual data transmission begins. This preliminary setup allows the system to optimize antenna port activation states in advance based on predicted transmission requirements, ensuring that sufficient antenna ports are activated to maintain transmission distance while avoiding unnecessary power consumption from over-activation.

AI summary
According to an embodiment of the disclosure, a method of operating a user equipment (UE) to control an antenna port of the UE in a wireless communication system includes selecting a band for receiving control information and data at an initial access of the UE, reporting to the base station whether activation of the antenna port is supported, receiving antenna port activation indication information from the base station, and determining whether to activate the antenna port based on the received antenna port activation indication information.
