Carrier Activation Control via Power Status Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication systems face inefficiencies in activating secondary carriers between mobile stations and base stations in multi-carrier environments, particularly in managing carrier activation status effectively.
Innovation Solution
A method where a mobile station requests activation of secondary carriers from a base station through a primary carrier, with activation request information determined by the mobile station's power status, and the base station responds with activation indication messages, allowing efficient carrier management and activation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple carriers are activated to increase data transmission capacity, then productivity is improved, but use of energy increases
Solution Approach 1:
The system dynamically adjusts the number of activated carriers based on the mobile station's power mode. When in power-saving mode, fewer carriers are activated to reduce energy consumption. When in high-performance mode, more carriers are activated to maximize data transmission capacity. This dynamic adaptation resolves the contradiction between productivity and energy usage.
Solution Approach 2:
The invention changes the operational parameters of the communication system by activating or deactivating carriers based on power status. The base station receives power mode information from the mobile station and adjusts carrier activation status accordingly, transforming the system from a static carrier configuration to a parameter-adjustable configuration that optimizes both performance and energy efficiency.
2Productivity
If carrier activation status is not effectively managed, then device complexity increases, but productivity decreases
Solution Approach 1:
The system implements a feedback mechanism where the mobile station reports its power mode status to the base station, and the base station responds by adjusting carrier activation status. This closed-loop feedback system automates carrier management, reducing complexity while improving productivity through efficient resource allocation.
Solution Approach 2:
The mobile station autonomously determines its power mode status and communicates this information to the base station, enabling self-service carrier management. The system automatically adjusts carrier activation based on reported power status without requiring manual intervention, simplifying management while optimizing performance.

AI summary
The present invention relates to a method and a device for managing carriers allocated to a terminal in a broadband wireless access system that supports multi-carrier. A method for managing carriers by a terminal in a broadband wireless access system supporting multi-carrier includes transmitting, to a base station, activation requests information for requesting the activation of at least one second carrier allocated from the base station through a first carrier according to the power state of the terminal, receiving, from the base station, a first message that includes activation indication information for indicating the activation of at least one target carrier of the at least one second carrier, and transmitting to the base station a second message which notifies the base station whether the at least one target carrier is ready per activation.
