UE Connection Control for Power Reduction in Multi-RAT Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G wireless communication systems, user equipment (UE) experiences increased power consumption due to unnecessary connections with secondary base stations, even when not required, as existing systems lack efficient methods to determine the need for a connection based on communication requirements.
Innovation Solution
A method and apparatus for determining whether a terminal needs a connection with a second base station in a multi-radio access technology (RAT) wireless communication system, where the terminal performs minimal measurements based on communication requirements and radio resource information, and the base station transmits a measurement configuration message only when necessary, allowing the terminal to decide on signal measurement and connection establishment.

Engineering Contradiction Analysis
1Productivity
If the UE establishes additional connection with the SeNB according to MeNB instruction, then the network coverage and data transfer rate are improved, but the power consumption of the UE is increased
Solution Approach 1:
The patent changes the parameter of connection establishment from unconditional (based on MeNB instruction alone) to conditional (based on communication requirements). The UE evaluates whether dual connection is actually needed based on traffic characteristics, service type, and channel conditions before establishing connection with SeNB, thereby avoiding unnecessary power consumption while maintaining high data transfer rates when required
Solution Approach 2:
The UE performs self-evaluation of its communication requirements and autonomously determines whether dual connection is necessary. Instead of blindly following MeNB instructions, the UE assesses its own traffic needs, service requirements, and channel conditions to decide whether to establish connection with SeNB, making the system more energy-efficient through intelligent self-management
2Area of stationary object
If the UE maintains connection with both MeNB and SeNB, then the network coverage is improved, but the device complexity is increased
Solution Approach 1:
The patent introduces dynamic parameters for evaluating connection necessity, including traffic characteristics, service type, and channel conditions. Based on these parameters, the UE intelligently determines whether to maintain dual connection or single connection, simplifying connection management while ensuring adequate network coverage through conditional dual-connectivity

AI summary
The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as long term evolution (LTE). The present disclosure relates to a wireless communication system supporting a multi-radio access technology (RAT). A method of operating a base station (BS) supporting a first RAT is provided. The method includes receiving information indicating a communication requirement from a terminal, determining whether the terminal needs to be connected with a different BS through a second RAT on the basis of the received information indicating the communication requirement, and if the terminal needs to be connected with the different BS through the second RAT, transmitting to the terminal a measurement configuration message for the second RAT.
