Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current electronic devices face inefficiencies in searching for an optimum beam for 5G communication due to increased power consumption and longer search times, especially when using multiple 5G antenna modules, which can result in decreased gain and increased search time due to factors like antenna location, user grip, and directional strength of signals.
Innovation Solution
An electronic device with multiple antennas and array antennas, where a control circuit manages the activation and deactivation of these antennas based on receive sensitivities to form optimal beams for communication, using a first communication circuit for individual antennas and a second communication circuit for array antennas, and includes sensors to detect user grip and adjust antenna usage accordingly.

Engineering Contradiction Analysis
1Reliability
If multiple 5G antenna modules are used to improve communication performance, then the reliability and coverage are improved, but the power consumption increases and the beam search time increases
Solution Approach 1:
The system dynamically changes the operational parameters of antenna modules based on measured receive sensitivities. By adjusting which antenna modules are active and their transmission power levels according to real-time performance metrics, the system achieves reliable communication while minimizing power consumption compared to having all antenna modules continuously active at full power
Solution Approach 2:
The patent implements dynamic selection and activation of antenna modules based on measured receive sensitivities. The system continuously monitors performance and adapts its configuration by activating only the necessary antenna modules for current communication conditions, making the antenna system flexible and adaptive rather than static
2Reliability
If multiple 5G antenna modules are used to improve communication performance, then the reliability is improved, but the beam search time increases
Solution Approach 1:
The system performs preliminary measurements of receive sensitivities for each antenna module before initiating beamforming operations. By pre-characterizing the performance of each antenna module and storing this information, the system can quickly select appropriate antennas and beams without performing exhaustive searches, significantly reducing beam search time while maintaining communication reliability
3Reliability
If antenna modules are continuously activated to maintain communication readiness, then the reliability is improved, but the power consumption increases
Solution Approach 1:
Instead of continuously activating all antenna modules, the system activates only the necessary subset of antenna modules based on measured receive sensitivities and current communication requirements. This partial action approach maintains adequate communication readiness by having available multiple antenna options without the excessive power consumption of keeping all modules continuously active at full power
