Interference Manager Mitigating Local Intermodulation in Multi-RAT UE
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In multi-radio access technology and multi-connectivity environments, concurrent transmissions can lead to intermodulation interference, affecting both uplink and downlink transmissions and causing data contention, which compromises data integrity and network efficiency, leading to increased power consumption and subcarrier reallocation needs.
Innovation Solution
An interference manager in user equipment determines and mitigates local interference by reconfiguring its wireless communication hardware, sending request messages to base stations to adjust their configurations accordingly, thereby minimizing intermodulation interference across different radio access technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If concurrent transmissions are performed using multiple radio access technologies, then data transmission capability is improved, but intermodulation interference occurs between frequency components
Solution Approach 1:
The UE determines an alternative configuration of wireless communication hardware before interference occurs, and sends a request message to the base station to switch to this configuration proactively, preventing intermodulation interference from degrading transmission performance
Solution Approach 2:
The patent changes hardware configuration parameters (such as RF chain allocation, antenna configuration, or transmission power settings) to an alternative configuration that eliminates the intermodulation interference while maintaining concurrent transmission capability
2Reliability
If interference condition is not mitigated, then data contention and losses occur, but re-transmitting data increases power consumption
Solution Approach 1:
The UE takes preliminary action by determining an alternative hardware configuration and requesting it from the base station before interference degrades data transmission, thereby preventing data losses that would require power-consuming re-transmissions
3Productivity
If subcarriers are re-allocated to mitigate interference, then network efficiency improves, but device complexity increases
Solution Approach 1:
The UE autonomously determines the alternative hardware configuration and initiates the request message to the base station, performing self-service rather than requiring complex network-side interference analysis and configuration management

AI summary
The present disclosure describes systems and methods directed to mitigating a local interference condition caused by concurrent transmissions in a multi-radio access technology and multi-connectivity environment. For a user equipment (110) transmitting data in a multi-radio access technology / multi-connectivity environment, an interference manager application (218) directs the user equipment (110) to determine (705) that an interference condition exists local to user equipment (110). The interference manager application directs the user equipment (110) to determine a configuration of the user equipment wireless-communication hardware (204, 206, 208, 210) to mitigate the local interference condition and directs the user equipment (110) to transmit (715) a request message to a base station (412), causing the base station (412) to configure (725) wireless-communication hardware (254, 256, 258) of the base station (412) to receive data (750) transmitted by the user equipment (110) in accordance with the determined configuration of the user equipment wireless-communication hardware (204, 206, 208, 210) that mitigates the determined local interference condition.
