Multi-Link Channel Access Using Link-Specific STR Capability Signaling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication systems struggle with channel access protocols in multi-link environments, particularly for devices with varying simultaneous transmission and reception (STR) capabilities, leading to interference and inefficiencies in channel access and throughput.
Innovation Solution
Methods for indicating STR capability information with finer granularity, using rules and configurations to ensure fair channel access and reduce cross-channel interference by differentiating STR capabilities among multiple links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If channel access protocols are used in multi-link environments without differentiating STR capabilities, then devices can operate on multiple links, but interference and inefficiencies occur in channel access and throughput
Solution Approach 1:
The patent applies local quality by differentiating STR capability indicators for different links. Each link is assigned a specific STR capability indicator (first indicator for STR-capable links, second indicator for non-STR links), allowing the system to treat each link according to its specific capability characteristics, thereby reducing interference and improving throughput
2Productivity
If STR capability information is indicated with coarse granularity, then device complexity is reduced, but channel access efficiency and interference management deteriorate
Solution Approach 1:
The patent segments the STR capability indication into different types (first STR capability indicator for links supporting simultaneous transmission and reception, second STR capability indicator for links that do not support it). This segmentation allows for more precise channel access management while keeping each individual indicator simple and manageable
Solution Approach 2:
The patent changes the parameter of capability indication granularity by introducing link-specific STR capability indicators rather than a single aggregate indicator. This parameter change enables finer control over channel access behavior on different links without excessively increasing overall system complexity

AI summary
Methods and systems for securely sending user plane data from a base station to an Artificial Intelligence (AI) server via a mobile telecommunication network are disclosed herein. A method performed by the base station located in a Radio Access Network (RAN) includes: sending an interface setup request to the (AI) server, receiving an interface setup response from the AI server, establishing, by exchanging cryptographic keys using an Internet Key Exchange (IKE) protocol, a data transport tunnel between the base station and the AI server based on an Internet Protocol Security (IPSec) network protocol, and sending the user plane data from the base station to the AI server for training artificial intelligence based models.
