Multi-Carrier Management Base Station Primary Carrier Selection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems supporting multi-carriers, the inefficient use of radio resources and increased load on base stations occur due to the transmission of traffic indication messages across different primary carriers used by multiple terminals in sleep mode.
Innovation Solution
A method where the base station manages multi-carriers by selecting a common carrier for a group of terminals to use as the primary carrier, reducing the need for multiple carriers and optimizing resource usage through the formation of terminal groups and efficient communication protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the base station transmits traffic indication messages through different primary carriers for each terminal, then each terminal can receive its specific traffic indication, but the radio resource usage becomes inefficient and the base station load increases
Solution Approach 1:
The patent merges multiple primary carriers into a single common primary carrier for transmitting traffic indication messages to multiple terminals. Instead of using separate primary carriers for each terminal, the base station selects one common primary carrier that all terminals can monitor, thereby consolidating control channel transmissions and improving radio resource efficiency while maintaining reliable message delivery to all terminals.
2Reliability
If the base station transmits traffic indication messages through different primary carriers for each terminal, then each terminal can receive its specific traffic indication, but the base station load increases
Solution Approach 1:
The patent combines multiple control channel transmissions into a single transmission on a common primary carrier. By merging the traffic indication message transmissions that would otherwise occur on multiple separate primary carriers into one unified transmission, the base station reduces its processing load and improves productivity while ensuring all terminals receive their traffic indications through the shared carrier.
3Adaptability or versatility
If multiple primary carriers are used for terminals in sleep mode, then each terminal can be addressed individually, but the multi-carrier management becomes complex and radio resources are wasted
Solution Approach 1:
The patent makes a single primary carrier universal by enabling it to serve multiple terminals simultaneously for traffic indication purposes. The common primary carrier is configured to carry traffic indication messages for multiple terminals, allowing the system to maintain individual terminal addressing capability while using a unified carrier structure, thereby reducing management complexity and avoiding radio resource waste.

AI summary
A multi-carriers management device of a communication system supporting multi-carriers requests a terminal attempting to enter a sleep window to change a primary carrier, and transmits a control message to the terminal through the changed primary carrier during the sleep window.
