If multiple antenna panels are configured for high-frequency communication, then signal transmission distance is improved, but device complexity increases
Solution Approach 1:
The antenna system is divided into multiple independent antenna panels, each capable of being independently activated or deactivated. This segmentation allows the system to manage complexity by treating each panel as a separate manageable unit rather than a monolithic system, while still achieving extended transmission distance through coordinated operation of multiple panels.
Solution Approach 2:
The antenna panels are configured with dynamic state transitions between activated and deactivated states. The network device can dynamically control which panels are active based on communication requirements, allowing the system to adapt its complexity level to match the actual transmission needs, thus managing the trade-off between transmission distance and operational complexity.
2Reliability
If antenna panels are kept in activated state for signal measurement, then communication reliability is improved, but energy consumption increases
Solution Approach 1:
Instead of keeping antenna panels continuously activated, the system employs periodic activation where panels are switched to activated state only when signal measurement or data transmission is required. The network device controls the timing of these activations, allowing panels to return to deactivated state during periods when communication activities are not needed, thus reducing overall energy consumption while maintaining communication reliability when required.
Solution Approach 2:
The antenna panels are designed to autonomously transition between states based on network device instructions without requiring continuous power. When deactivated, panels consume minimal energy while maintaining their operational capability, and can be quickly reactivated when needed, effectively serving themselves by minimizing energy consumption during idle periods while remaining ready for communication tasks.
