Dynamic Antenna Group Selection for Millimeter-Wave UE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current multi-mode user equipment (UE) designs for millimeter-wave frequency bands require multiple antennas, leading to increased hardware costs due to the need for additional baseband processing units and complexity, which is not dynamically adaptable to changing network conditions.
Innovation Solution
A method where user equipment (UE) determines reception quality parameters for multiple antenna groups and sends messages to a server indicating these parameters, allowing the server to select optimal antenna groups for communication, thereby reducing unnecessary antenna usage and improving communication reliability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antennas are designed on multi-mode UE for millimeter-wave frequency bands, then communication reliability is improved, but hardware cost and device complexity increase due to additional baseband processing units
Solution Approach 1:
The patent implements dynamic antenna group selection where the UE determines reception quality parameters for multiple antenna groups and reports them to the network. The network then dynamically selects the optimal antenna group based on real-time channel conditions, allowing the system to adapt between using more or fewer antennas depending on actual communication needs rather than always using all antennas, thus reducing hardware cost while maintaining reliability
Solution Approach 2:
The patent changes the operational state of antenna groups by selecting different antenna groups based on reception quality parameters. Instead of all antennas being active simultaneously, the system transitions between different antenna group configurations, effectively changing which antennas are in use based on channel conditions, thereby reducing the need for all baseband processing units to operate at full capacity
