Antenna Selection Based on User Identity and Context
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices with advanced features like MIMO and carrier aggregation consume significant resources and battery power, leading to inefficiencies in battery life and network resource allocation, as these features are not always necessary for all users or contexts.
Innovation Solution
A mobile communication device adapts its antenna usage based on a rule set and operation context, using a client application to authenticate users, retrieve and apply antenna operation settings from a server, and restrict or enable MIMO and carrier aggregation features depending on the user's identity, location, and activity, such as disabling supplementary antennas during school hours to conserve battery and network resources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If MIMO and carrier aggregation technologies are enabled to meet 5G bandwidth requirements, then network capacity and data throughput are improved, but battery power consumption and device resource usage increase significantly
Solution Approach 1:
The patent implements dynamic antenna selection where the mobile device switches between using all antennas (for high throughput) and using only a subset of antennas (for power saving) based on real-time evaluation of operational context and user identity. The system dynamically adjusts the active antenna configuration rather than maintaining a fixed state, resolving the contradiction between maintaining high productivity and reducing energy consumption.
Solution Approach 2:
The system changes the operational parameters of the antenna system by receiving and applying rule sets that define different antenna configurations for different contexts. The mobile device transitions between different antenna usage modes (full MIMO vs. reduced antenna usage) by changing system parameters based on external inputs such as user identity, location, and time, thereby optimizing the balance between throughput and power consumption.
2Productivity
If all antennas are used simultaneously for enhanced 5G performance, then network capacity is improved, but network resource allocation efficiency deteriorates when full capacity is not needed
Solution Approach 1:
The patent applies local quality by enabling advanced antenna features only in specific local contexts where they are truly needed. Instead of uniformly enabling all antennas everywhere, the system selectively activates full antenna capacity only when the operational context (user identity, location, time, activity) indicates high-demand scenarios, while using reduced antenna configurations in lower-demand contexts, thereby optimizing network resource allocation efficiency.
3Adaptability or versatility
If advanced 5G features are always enabled, then device capabilities are improved, but device complexity and resource management burden increase
Solution Approach 1:
The system implements self-service by automatically evaluating operational context and applying appropriate antenna configurations without requiring manual user intervention. The mobile device autonomously manages its antenna resources by processing contextual information (location, time, user identity) and automatically switching between different antenna modes based on pre-configured rules, thereby reducing the complexity burden on users while maintaining high adaptability.

AI summary
A mobile communication device that adapts its usage of antennas based on a rule set and an operation context. The device comprises a plurality of antennas, a radio modem, a processor, a non-transitory memory, and a client application stored in the non-transitory memory. When executed by the processor, the application receives a biometric input for authenticating a session of a user on the device, wherein the biometric input is associated with a biometric profile, sends a request for a rule set to a server computer, and receives the rule set. The application further stores the rule set, evaluates the rule set based on the operation context to determine an antenna operation setting, and commands the radio modem to configure itself to the antenna operation setting, whereby the radio modem is restricted from using all of the plurality of antennas at the same time in at least some operation contexts.
