MBS Frequency Segmentation for Efficient Multicast Broadcast Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE technology, MBS frequency allocation leads to inefficient use of frequency resources, either occupying too much bandwidth when a large data volume is transmitted or causing excessive power consumption when a wide bandwidth is used unnecessarily.
Innovation Solution
A method and device for dynamically allocating MBS transmission frequencies, allowing MBS and common services to use different frequency ranges, optimizing resource usage and reducing power consumption.

Engineering Contradiction Analysis
1Quantity of substance
If MBS uses a narrow frequency range (same as common services), then frequency resource occupation is reduced, but common service transmission is affected when large data volume MBS is transmitted
Solution Approach 1:
The patent divides the frequency domain resources into separate frequency ranges: one for common services and another for MBS. This segmentation allows MBS to use a dedicated frequency range that can be dynamically adjusted based on data volume requirements, preventing interference with common service transmission while ensuring reliable MBS delivery even when large data volumes are transmitted.
2Adaptability or versatility
If MBS uses a broad frequency range (same as common services), then frequency resource flexibility is improved, but power consumption increases for both MBS and common service terminals
Solution Approach 1:
By segmenting frequency ranges into dedicated MBS and common service bands, terminals can operate in narrower frequency ranges specific to their service type. MBS terminals only need to monitor and process MBS-specific frequency resources, while common service terminals focus on their designated frequencies, significantly reducing overall power consumption compared to monitoring a broad unified frequency range.
Solution Approach 2:
The patent applies local quality by optimizing frequency resource allocation for specific service types. MBS terminals are configured with dedicated frequency range information tailored to MBS requirements, while common service terminals receive configurations optimized for their needs. This localized optimization ensures each terminal type processes only necessary frequency resources, minimizing power consumption while maintaining service-specific performance.
3Productivity
If MBS occupies large bandwidth for large data volume, then MBS transmission capacity is improved, but frequency resource efficiency deteriorates when common services are also transmitted
Solution Approach 1:
The patent segments frequency domain resources into dedicated MBS frequency ranges and common service frequency ranges. This allows MBS to occupy large bandwidth within its dedicated frequency range when large data volume transmission is required, while common services operate independently in their own frequency ranges. The segmentation ensures that MBS can achieve high transmission capacity without reducing frequency resource efficiency for common services, as both services operate in isolated frequency domains.
