Base Station Frequency Band Indication for Mobile Scheduling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques fail to efficiently utilize all available frequency bands for communication control in mobile communication systems, leading to reduced frequency efficiency when multiple mobile stations transmit reception quality information from the same frequency band, resulting in inadequate resource allocation by the base station.
Innovation Solution
The base station apparatus receives and transmits frequency band indication information to the mobile station, allowing it to distribute the transmission of reception quality information from different frequency bands, thereby enabling efficient use of all allocatable resources for adaptive modulation and coding and frequency selective scheduling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple mobile stations transmit reception quality information from the same frequency band, then the base station can maintain simple scheduling procedures, but the frequency efficiency of communication control is reduced
Solution Approach 1:
The invention segments the frequency bands into multiple groups and assigns different mobile stations to report reception quality information from different frequency band groups. This segmentation ensures that multiple mobile stations do not transmit from the same frequency band simultaneously, thereby improving frequency efficiency while maintaining manageable scheduling complexity through structured organization.
Solution Approach 2:
The invention applies local quality by allowing different mobile stations to report reception quality information from different local frequency band regions. Each mobile station is assigned to report from specific frequency bands based on its characteristics and channel conditions, optimizing the overall frequency efficiency of the system.
2Manufacturing precision
If the base station allocates resources based on detailed reception quality information from multiple frequency bands, then the resource allocation precision is improved, but the complexity of information processing increases
Solution Approach 1:
The invention divides the frequency spectrum into multiple bands and organizes reporting mobile stations into groups, each responsible for specific frequency bands. This segmentation allows the base station to process reception quality information in a structured manner, improving resource allocation precision across different frequency regions while managing processing complexity through systematic organization.
Solution Approach 2:
The invention changes the parameter of frequency band assignment dynamically by assigning different mobile stations to report from different frequency bands. This parameter change enables the base station to obtain comprehensive reception quality information across multiple frequency bands, improving resource allocation precision without overwhelming processing complexity through systematic management.

AI summary
When a mobile station apparatus transmits to a base station apparatus each of reception quality information obtained from a plurality of frequency bands, the base station apparatus controls where the reception quality information to be transmitted first is obtained, and thereby it is possible to efficiently use all resources (frequency bands) to be allocated to the mobile station apparatuses and to improve the frequency efficiency of the communication control (scheduling) by the base station apparatus. The base station apparatus (100) transmits to the mobile station apparatus (200) frequency band indication information which indicates from which frequency band the reception quality information is obtained to be transmitted, which is included in a radio resource control signaling.
