Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face challenges in optimizing antenna performance for carrier aggregation (CA) and standalone communication configurations due to reliance on 'CA configured' signals, leading to suboptimal performance.
Innovation Solution
The method involves adapting the communication configuration of the antenna and circuit based on 'CA active' or 'CA inactive' signals, allowing the device to switch between configurations optimally suited for CA or standalone operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the electronic device determines communication configuration based on 'CA configured' signal, then the device can support carrier aggregation capability, but the antenna performance is suboptimal when standalone communication occurs under CA configuration
Solution Approach 1:
The patent applies dynamics by making the antenna configuration changeable based on actual operation mode. The system dynamically switches between CA configuration and standalone configuration according to received signaling ('CA active' or 'CA inactive') rather than using a fixed configuration based on 'CA configured' signal. This allows the antenna parameters to adapt in real-time to the actual communication mode, resolving the contradiction between supporting multiple modes and maintaining optimal performance in each mode.
Solution Approach 2:
The patent changes physical parameters of the antenna system based on operation mode. Specifically, it adjusts antenna configuration parameters (such as impedance, matching networks, or circuit topology) according to whether CA or standalone communication is actually active. This parameter adaptation ensures optimal antenna performance for each communication mode while maintaining the ability to support both CA and standalone operations.
2Productivity
If the electronic device uses fixed communication configuration, then the device structure is simple, but the device cannot optimize performance for different communication modes
Solution Approach 1:
The patent implements feedback by using signaling from the network ('CA active' or 'CA inactive') to determine the actual operation mode, then adjusting the antenna configuration accordingly. This closed-loop approach ensures the antenna is always optimized for the current communication mode without requiring complex prediction or manual configuration, achieving high communication efficiency with manageable system complexity.
Solution Approach 2:
The patent makes the antenna system multi-functional by designing it to support both CA and standalone communication modes through a single configurable architecture. Rather than requiring separate antenna systems for each mode, the universal design allows one antenna system to perform multiple functions by changing its configuration parameters based on the active communication mode.

AI summary
An electronic device includes a communication circuit, a plurality of antennas that are fed with power from the communication circuit, and a processor that controls the communication circuit. The processor is configured to receive a first signal for indicating initiation of configuration for carrier aggregation. The processor is also configured to change the configuration of at least one of the antennas or the communication circuit to perform the carrier aggregation if a second signal for indicating operation initiation of the carrier aggregation is received from a base station.
