UE Capability Messaging for Extraterrestrial Base Stations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In satellite communication, the existing UE capability information messages sent to extraterrestrial base stations are often large and inefficient, leading to wasteful use of spectrum and increased risk of errors due to the inclusion of unnecessary carrier aggregation combinations and band capabilities.
Innovation Solution
Incorporating new signaling information elements in the UE capability enquiry message to instruct the UE to only send specific, relevant information, such as support for a single RF band and essential LTE features, thereby reducing the size of the UE capability information message and ensuring only pertinent data is transmitted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the UE transmits complete capability information including all carrier aggregation combinations and band capabilities, then the UE provides comprehensive information to the extraterrestrial base station, but the message size becomes large causing inefficient spectrum use and increased error risk
Solution Approach 1:
The patent extracts and removes unnecessary carrier aggregation combination information from the UE capability information message. The extraterrestrial base station sends a capability enquiry message that specifically requests only the RF band capabilities and essential LTE features, causing the UE to transmit only these requested parameters rather than all possible capabilities, thereby reducing message size while maintaining necessary information.
Solution Approach 2:
The patent changes the parameters of the capability enquiry message by introducing new signaling information elements that specify which capability parameters are required. This modifies the traditional capability exchange mechanism to request only essential parameters (RF band support and key LTE features) rather than complete capability sets, reducing the quantity of transmitted data.
2Adaptability or versatility
If the UE capability information message includes all supported features and combinations, then the UE demonstrates full capability, but the spectrum efficiency decreases and system capacity management becomes less effective
Solution Approach 1:
The patent applies partial action by having the UE transmit only the necessary capability information required for the specific extraterrestrial base station configuration. Instead of transmitting all possible capabilities (excessive action), the UE sends only the RF band and essential LTE feature information that is actually needed for attachment, optimizing spectrum efficiency while maintaining adequate capability demonstration.
3Loss of information
If larger blocks of capability data are transmitted, then more comprehensive information is conveyed, but the risk of transmission errors increases
Solution Approach 1:
The patent removes unnecessary data from the capability information message, extracting only the essential RF band and LTE feature capabilities that are required for the attachment process. This reduction in data volume decreases the likelihood of transmission errors while maintaining the necessary information for successful UE attachment to the extraterrestrial base station.

AI summary
Embodiments of the present disclosure are directed to systems and methods for limiting user equipment (UE) capability information messaging received by an extraterrestrial base station (EBS). One or more broadcast signals are transmitted from the EBS and detected by a UE. Upon detecting the broadcast signals, the UE requests to attach to the EBS. In aspects, the EBS will first authenticate the UE's identity. Then, a capability enquiry message is transmitted to the UE specifying what information the EBS would like and requesting that carrier aggregation information not be included. The UE then sends a UE capability information message without carrier aggregation information, thereby reducing the UE capability information transmitted between the UE and the EBS.
