Aerial Vehicle User Equipment Carrier Assignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mobile communication networks do not effectively differentiate between user equipment aboard aerial vehicles and terrestrial user equipment, leading to increased radio interference and degraded uplink performance for terrestrial users due to high-bandwidth data transmissions from aerial vehicles.
Innovation Solution
The method involves detecting user equipment aboard aerial vehicles and assigning them a specific mobile radio carrier or frequency range to minimize interference, while shifting terrestrial user equipment to different carriers to avoid interference, using techniques such as carrier aggregation.

Engineering Contradiction Analysis
1Productivity
If aerial vehicle-based user equipment transmits high-bandwidth data in uplink direction, then data transmission capability is improved, but radio interference to terrestrial users is increased
Solution Approach 1:
The patent segments the mobile radio spectrum into different frequency ranges carriers, assigning specific carriers to aerial vehicle-based user equipment while allowing terrestrial users to use other carriers. This frequency domain segmentation isolates the high-bandwidth aerial vehicle transmissions from terrestrial user communications, enabling high data transmission capability for aerial vehicles without causing excessive radio interference to terrestrial users.
Solution Approach 2:
The patent applies different carrier frequency assignments based on the local characteristics and location of user equipment. Aerial vehicle-based user equipment is assigned specific mobile radio carriers that are differentiated from carriers used by terrestrial users. This local differentiation ensures that high-bandwidth transmissions from aerial vehicles occur on frequencies that minimize interference to terrestrial users in the same geographic area.
2Device complexity
If conventional mobile communication networks treat all user equipment uniformly, then network simplicity is maintained, but uplink performance for terrestrial users is degraded
Solution Approach 1:
The patent changes the carrier frequency parameter based on user equipment type and location. The network detects whether user equipment is aboard an aerial vehicle or is terrestrial, and then assigns different carrier frequencies accordingly. This parameter change (carrier frequency assignment) allows the network to maintain relative simplicity in its operation while significantly improving uplink performance for terrestrial users by avoiding interference from aerial vehicle transmissions.
3Object-generated harmful factors
If aerial vehicle-based user equipment uses specific mobile radio carriers, then radio interference is reduced, but carrier frequency assignment complexity is increased
Solution Approach 1:
The patent implements a feedback mechanism where the network detects the location and type of user equipment (aerial vehicle vs. terrestrial) and uses this information to dynamically assign appropriate carrier frequencies. The network monitors uplink transmissions and adjusts carrier assignments based on detected interference patterns and user equipment characteristics. This feedback-based approach reduces radio interference by optimizing carrier frequency assignments while managing the complexity through automated network-side processing.
