Base Station Service Indication for Carrier Aggregation Conflicts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications, carrier aggregation between cells with different frequency bands can lead to service conflicts due to shared physical frequencies across different frequency channel numbers, causing issues in service indication and management.
Innovation Solution
A method where a base station sends service indication information that multiplexes the identifier of one frequency channel number within the indication of another, ensuring that services associated with the same physical frequency are correctly identified and managed, thereby avoiding conflicts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If carrier aggregation is performed between cells with different frequency bands, then service coverage and capacity are improved, but service conflicts occur due to shared physical frequencies across different frequency channel numbers
Solution Approach 1:
The patent segments the service indication by introducing a frequency channel number identifier field in the measurement configuration message. This segmentation allows the system to distinguish between different frequency channel numbers (e.g., N1 for band 12, N2 for band 17) that share the same physical frequency, thereby preventing service conflicts while maintaining carrier aggregation functionality across multiple frequency bands
Solution Approach 2:
The patent introduces a frequency channel number identifier as an intermediary element in the service indication process. This identifier acts as a mediator between the physical frequency and the service configuration, enabling the system to correctly identify and manage services associated with different frequency channel numbers even when they share the same physical frequency, thus resolving the service conflict issue
2Measurement precision
If service indication information is sent for multiple frequency channel numbers, then service management accuracy is improved, but message complexity increases due to need for distinguishing different frequency channel numbers
Solution Approach 1:
The patent embeds the frequency channel number identifier within the existing measurement configuration message structure. By nesting this identifier field inside the existing service indication information, the patent achieves precise service indication for multiple frequency channel numbers without significantly increasing overall message complexity, as the identifier is integrated into the existing signaling framework rather than requiring separate messages

AI summary
Embodiments of the present disclosure provide a service indication method, a base station, a terminal, and a system. The method includes: sending, by the base station, first service indication information to the terminal, where the first service indication information includes an identifier of a first frequency channel number and an identifier of a first service associated with the first frequency channel number; determining, by the base station, a second service associated with a second frequency channel number; and sending second service indication information to the terminal, where the second service indication information includes the identifier of the first frequency channel number and an identifier of the second service. In the solution in the embodiments of the present disclosure, after indicating a service associated with a frequency channel number, a service identifier may further indicate a service associated with another frequency channel number with a same physical frequency.
