Solution Overview
Problem
Current wireless communication systems face challenges in effectively controlling data transmission and managing load in radio communication technologies like WiFi or unlicensed bands, particularly in managing user equipment access and transmission/reception configurations.
Innovation Solution
A method where user equipment transmits capability configuration information to network nodes, allowing for triggered communication environment configurations, including activating or deactivating Licensed Wireless Access (LWA) connections based on user selection and network permissions, to optimize data transmission and load management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If LWA connection is activated to improve data transmission efficiency, then communication efficiency is improved, but device complexity increases due to dual connection management
Solution Approach 1:
The patent implements dynamic connection management where the LWA connection is activated or deactivated based on real-time conditions. The network node receives capability configuration information from the UE and triggers communication environment configuration to dynamically establish or release LWA connections, allowing the system to adapt between single WLAN and dual LWA-WLAN connection states according to transmission needs.
2Productivity
If capability configuration information is transmitted to enable network-based LWA activation, then communication efficiency is improved, but information transmission overhead increases
Solution Approach 1:
The patent extracts only the essential capability configuration information needed for LWA activation from the UE and transmits it to the network node. This selective information transmission enables the network to make informed decisions about LWA connection establishment without requiring the UE to process or transmit complete configuration datasets, reducing overhead while maintaining functionality.
3Adaptability or versatility
If triggered communication environment configuration is implemented to optimize LWA activation, then adaptability is improved, but control complexity increases
Solution Approach 1:
The patent implements a triggered configuration mechanism where the network node autonomously receives capability information from the UE and independently decides whether to activate LWA connections. The network node self-manages the communication environment configuration by triggering appropriate activation or deactivation procedures based on the received capability configuration information, eliminating the need for complex UE-side control mechanisms.

AI summary
A method for controlling a data transmission state by a terminal in a wireless communication system may comprise: transmitting capability configuration information of the terminal to a node of a network; applying a triggered communication environment configuration on the basis of the capability configuration information from the node; transmitting, to the node, first connection configuration information related to a wireless local area network (WLAN) connection configuration; and applying a first communication environment reconfiguration triggered from the node on the basis of the first connection configuration information, wherein the capability configuration information includes LWA function permission information of the terminal.
