FlexE Bearer Frame Structure for Sub-5G Client Bandwidths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies face challenges in efficiently transmitting client services at speeds lower than 5 G using the FlexE protocol due to limited slot numbers and large bandwidth granularity, making it difficult to accommodate a variety of client services with varying bandwidth requirements.
Innovation Solution
A fine-grained frame structure is introduced, dividing the 5G-rate FlexE slot pipeline into sub-slots that can support multiple slot sizes, allowing for the transmission of client services with different slot sizes, including 2, 4, and 8 code blocks, and a general bearer frame structure is constructed to adapt to varying client code block sizes by adjusting slot size, number of slots, and number of frames in a multiframe.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fine-grained frame structure with multiple slot sizes is introduced, then adaptability to various client service bandwidth requirements is improved, but device complexity increases
Solution Approach 1:
The FlexE slot pipeline is divided into sub-slots of different granularities (2, 4, or 8 code blocks per sub-slot). This segmentation allows the system to accommodate client services with different bandwidth requirements by selecting appropriate sub-slot sizes, thereby improving adaptability without requiring complete redesign of the transmission framework.
Solution Approach 2:
The frame structure is designed to be dynamic, allowing the number of slots and sub-slots per frame to be adjusted based on the specific bandwidth requirements of client services. The system can flexibly configure the frame structure parameters (such as setting different numbers of frames in a multiframe) to match various transmission needs, achieving adaptability while maintaining manageable complexity through structured flexibility.
2Adaptability or versatility
If slot size is reduced to accommodate lower speed client services, then adaptability is improved, but delay time increases
Solution Approach 1:
By segmenting the slot pipeline into sub-slots of different sizes (2, 4, or 8 code blocks), the system can select larger sub-slot sizes for lower speed client services, thereby reducing the number of processing stages and minimizing delay time while still accommodating diverse bandwidth requirements.
Solution Approach 2:
The system changes the sub-slot size parameter dynamically based on client service requirements. For lower speed services, larger sub-slot sizes are used to reduce processing delay, while for higher speed services, smaller sub-slot sizes provide finer granularity. This parameter adjustment resolves the contradiction between adaptability and delay time.
