Multi-Radio Antenna Arbitrator for Coordinated RAT Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless user equipment devices with multiple antennas face challenges in selecting the optimal antenna for communication across different radio access technologies (RATs), leading to performance degradation and increased power consumption due to the lack of coordinated antenna usage across various communication types.
Innovation Solution
The implementation of a user equipment (UE) device with multiple antennas and processors that collect performance information from one RAT to determine the highest performing antenna and coordinate the selection of antennas across different RATs, such as cellular and short-range wireless communications, to improve communication efficiency and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple antennas are used for different RATs independently, then each radio can operate autonomously, but antenna performance degradation occurs due to lack of coordination and user grip effects
Solution Approach 1:
The patent combines antenna selection for multiple RATs under a unified coordination mechanism. The processor collects performance information from antennas used by different radios (cellular, WiFi, Bluetooth) and makes coordinated selection decisions, merging previously independent antenna selection processes into a single integrated system that considers all RATs simultaneously.
Solution Approach 2:
The patent creates a universal antenna selection mechanism that serves multiple RATs simultaneously. The same processor and performance information collection system are used to manage antenna selection for cellular, WiFi, and Bluetooth radios, making the antenna selection system multi-functional rather than dedicated to a single RAT.
2Productivity
If antenna selection is made independently for each RAT, then each radio can optimize its own performance, but overall power consumption increases due to lack of coordination
Solution Approach 1:
The patent merges antenna selection decisions across different RATs into a unified process. By collecting performance information from all radios and making coordinated selection decisions, the system avoids redundant operations and optimizes overall power consumption while maintaining communication efficiency for each individual RAT.
3Measurement precision
If performance information is collected from all antennas for all RATs, then optimal antenna selection can be made, but system complexity and processing overhead increase
Solution Approach 1:
The patent implements a universal performance information collection mechanism that serves multiple RATs. The same processor and measurement system are used to collect and evaluate antenna performance for cellular, WiFi, and Bluetooth radios, reducing redundancy while maintaining precise measurement capabilities across all RATs.

AI summary
A user equipment device (UE) may be configured to collect first performance information from antennas of a first plurality of antennas. The first plurality of antennas may be coupled to a first radio of the UE that may be configured to perform wireless communications according to a first RAT. The UE may determine, based on at least the first performance information, a highest performing antenna of the first plurality of antennas to use for communications according to the first RAT. Additionally, the UE may determine, also based on at least the first performance information, a first antenna of a second plurality of antennas to use for communications according to a second RAT. The second plurality of antennas may be coupled to a second radio of the UE that may be configured to perform wireless communications according to the second RAT.
