Broadcast Frame Zone Service Slicing for Mobile Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current broadcasting communication systems face challenges in achieving efficient reception performance, particularly for mobile terminals, due to high power consumption caused by frequent demodulation and increased signaling overhead resulting from service slicing for time diversity gain, while also needing to support both fixed and mobile terminals with varying service slicing configurations.
Innovation Solution
The system introduces the concept of dividing a frame into multiple zones with varying numbers of service slicings, allowing for efficient physical mapping and simultaneous data transmission to both fixed and mobile terminals, reducing power consumption by optimizing service slicing based on zone configurations and signaling overhead.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If service slicing is performed to achieve time diversity gain, then reliability is improved, but power consumption increases due to frequent demodulation
Solution Approach 1:
The patent applies local quality by differentiating service slicing configurations between zones. Fixed terminals receive services with higher slicing levels (more sub-slices) for enhanced time diversity, while mobile terminals receive services with lower slicing levels to reduce demodulation frequency and power consumption. This localized differentiation resolves the contradiction by tailoring the slicing strategy to specific terminal types and their respective requirements.
2Reliability
If service slicing is performed to achieve time diversity gain, then reliability is improved, but signaling overhead increases
Solution Approach 1:
The patent reduces signaling overhead by configuring different numbers of service slicings for different zones. The system dynamically adjusts slicing configurations based on terminal type, thereby reducing the amount of signaling information needed to be transmitted and processed. This localized quality approach optimizes the balance between achieving time diversity and minimizing signaling overhead.
3Device complexity
If uniform service slicing is applied to all services, then device complexity is reduced, but adaptability decreases for different terminal types
Solution Approach 1:
The patent segments the broadcast frame into multiple zones, each with different service slicing configurations optimized for specific terminal types. This segmentation allows the system to simultaneously support both fixed terminals (requiring high time diversity) and mobile terminals (requiring lower power consumption), thereby achieving adaptability without excessive complexity.
Solution Approach 2:
The patent implements local quality by assigning different service slicing levels to different zones based on the target terminal type. This allows the system to maintain simple configurations where needed while providing enhanced adaptability for different terminal requirements, resolving the contradiction between complexity and adaptability.

AI summary
An apparatus and method for configuring a broadcast service data in a digital broadcasting communication system are provided. The method includes mapping a first zone, corresponding to broadcast service data of a first type, and a second zone, corresponding to broadcast service data of a second type, in a frame individually. Preferably, the broadcast service data included in the first zone and the second zone is sliced into sub-slices according to a different number of service slicings for each zone.
