RF Port Selection via Context Information in Wireless Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic apparatuses using RFICs for wireless communication are inefficient in determining the appropriate RF port for signal transmission and reception, especially in complex communication environments like Bluetooth earphones, due to reliance on frequency band information alone, which limits the number of exceptions that can be processed.
Innovation Solution
An electronic apparatus that includes a communication circuit with multiple RF ports, a processor, and memory, where the processor determines the appropriate RF port for each frequency band based on both frequency band information and context information such as peripheral device connections, sensor data, and CA mode, enabling more efficient port selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the RF driver operates an RF port for each CA combination as exception processing, then the communication reliability is improved, but the device complexity increases
Solution Approach 1:
The patent applies universality by creating a unified port determination method that handles both常规 frequency band assignments and exceptional CA combinations through a single contextual evaluation framework. The processor evaluates context information (connected devices, signal strength, antenna availability) to universally determine appropriate RF ports regardless of whether the scenario is standard or exceptional, eliminating the need for separate exception processing logic in the RF driver.
Solution Approach 2:
The patent implements dynamics by making the RF port selection adaptive and context-dependent rather than static. The processor dynamically evaluates current communication environment context information and adjusts RF port assignments in real-time based on connected devices, signal conditions, and antenna availability, allowing the system to flexibly respond to varying CA combinations without increasing RF driver complexity.
2Ease of operation
If the RF port settings use only frequency band information, then the ease of operation is maintained, but the productivity decreases
Solution Approach 1:
The patent applies self-service by enabling the processor to automatically evaluate context information and determine optimal RF port assignments without manual intervention. The system self-adjusts port configurations based on detected communication environment context (connected devices, signal strength, antenna availability), maintaining ease of operation while significantly improving communication productivity through intelligent automated decision-making.
Solution Approach 2:
The patent implements feedback by continuously monitoring communication environment context information and using this feedback to dynamically adjust RF port selections. The processor evaluates real-time context data and adjusts port assignments accordingly, creating a closed-loop system that improves communication efficiency while requiring no changes in user behavior or additional manual configuration.
