UE Shared Antenna Allocation Using Cellular and Satellite Priorities
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user equipment (UE) devices face inefficiencies in allocating shared resources like antennas between cellular and satellite communication systems, leading to performance losses in either system due to concurrent usage, particularly with GNSS L5 and cellular systems, and conventional methods of switching resources are inefficient.
Innovation Solution
UE determines access to land-based or satellite communication systems based on multiple priority indications derived from wireless link metrics, application metrics, and service metrics, using shared antennas to optimize resource allocation through processor-controlled mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a shared antenna is used to access both satellite and land based wireless communication systems, then device complexity is reduced, but performance loss occurs in either system due to concurrent usage
Solution Approach 1:
The patent implements dynamic antenna allocation where the shared antenna is dynamically assigned to either satellite or land based communication systems based on real-time priority indications. The processor determines which system requires the antenna at any given moment by evaluating multiple metrics, allowing the system to adapt to changing communication needs and avoid performance degradation from concurrent access attempts.
Solution Approach 2:
The patent introduces an intermediary decision-making mechanism (the processor evaluating priority indications from multiple metrics) that mediates between the satellite and land based communication systems for access to the shared antenna. This intermediary evaluates various metrics and determines the optimal system to use the antenna at any given time, preventing direct conflict between the two systems.
2Ease of operation
If conventional switching methods are used to allocate the shared antenna, then ease of operation is maintained, but productivity is reduced due to inefficient resource allocation
Solution Approach 1:
The patent implements feedback mechanisms where the system continuously monitors multiple metrics including wireless link metrics, application metrics, and service metrics. This feedback loop allows the processor to make informed decisions about antenna allocation, continuously optimizing resource usage based on current system conditions rather than using fixed conventional switching methods.
Solution Approach 2:
The patent changes the parameters used for antenna allocation from simple conventional switching criteria to a multi-metric evaluation system. By considering wireless link metrics, application metrics, and service metrics, the system adjusts its antenna allocation decisions based on multiple varying parameters, significantly improving resource allocation efficiency compared to conventional single-criterion switching.

AI summary
Mechanisms are provided for a user equipment (UE) to determine to use a shared resource such as an antenna to access a land based wireless communication system or a satellite communication system. The UE can provide a first priority indication to indicate whether to access the land based wireless communication system based on one or more wireless link metrics of the land based wireless communication system or one or more application metrics for applications using the land based wireless communication system; and provide a second priority indication to indicate whether to access the satellite wireless communication system based on one or more service metrics provided by the satellite wireless communication system. The UE can determine to use the shared resources to access the land based wireless communication system or the satellite communication system based on the first priority indication and the second priority indication.
