Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interference and signal loss occur due to overlapping frequencies of transmitted and received signals from different wireless communication networks on user equipment, such as 5G FR2 and 6G networks, which are not effectively addressed by existing technologies.
Innovation Solution
User equipment indicates its frequency band usage capabilities to wireless communication networks, allowing them to configure and schedule operations to prevent interference by allocating non-overlapping frequency ranges or using time-domain multiplexing to manage simultaneous communication with both networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If user equipment communicates with multiple wireless networks simultaneously, then network connectivity and communication capability are improved, but frequency overlap causes interference and signal loss
Solution Approach 1:
The patent segments the frequency spectrum into distinct sub-ranges (first available frequency sub-range of intermediate frequency range, second available frequency sub-range outside intermediate frequency range) and allocates them to different networks. The transceiver is divided into multiple receivers (first receiver, second receiver) that operate on these segmented frequencies, preventing interference while maintaining connectivity to both networks
Solution Approach 2:
The patent introduces frequency domain dimensioning by operating different receivers on different frequency sub-ranges. The first receiver operates in the intermediate frequency range while the second receiver operates outside this range, creating a multi-dimensional frequency space that allows simultaneous network communication without interference
2Productivity
If frequency ranges are allocated to multiple networks, then communication capability is improved, but frequency overlap causes interference
Solution Approach 1:
The patent applies local quality by assigning specific frequency sub-ranges to specific networks based on their requirements. The first network receives signals in the first available frequency sub-range while the second network uses the second available frequency sub-range, giving each network its own optimized frequency locale without affecting the other
Solution Approach 2:
The patent introduces frequency conversion as an intermediary mechanism. The converter transforms signals from the second frequency sub-range to the intermediate frequency range, acting as a mediator that allows the system to maintain separate frequency allocations while enabling integrated processing and preventing direct interference between network signals
3Adaptability or versatility
If simultaneous communication with multiple networks is enabled, then network coexistence is improved, but signal conversion complexity increases
Solution Approach 1:
The patent achieves universality by designing a multi-functional transceiver system that can handle multiple frequency ranges and perform multiple operations (receiving, converting, processing) within a unified architecture. The system universally supports communication with different network types (5G FR2, 6G) using the same device, reducing overall system complexity despite the multi-frequency requirements

AI summary
User equipment may transmit and receive wireless signals to and from various communication networks. Furthermore, user equipment may indicate usage capabilities to the various wireless communication networks to enable the user equipment to transmit and/or receive wireless signals to and from at least two different communication networks. In particular, the user equipment may indicate usage capabilities of supporting both Frequency Range 2 (FR2) wireless signals of a fifth generation (5G) network and 7-24 gigahertz (GHz) wireless signals of a sixth generation (6G) network in an intermediate frequency range of the user equipment. The communication network(s) may then configure and/or schedule the user equipment based on the usage capabilities to enable the user equipment to simultaneously or non-simultaneously communicate using both the FR2 wireless signals and the 7-24 GHz wireless signals while preventing interference in the intermediate frequency range of the user equipment.
