Middle Node Shared Cell SCS Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication systems, particularly in O-RAN networks, configuring shared cells to efficiently manage multiple subcarrier spacings (SCS) is challenging due to resource waste and quality degradation, as existing methods struggle to effectively combine and process uplink data with different SCSs, leading to delays and inefficiencies.
Innovation Solution
A method and device for a middle node in a communication system that receives capability information and timing data from a controller, allowing it to efficiently process and combine uplink data with multiple SCSs, minimizing additional delay by transmitting combined data at optimized timing, thereby improving resource utilization and communication quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If multiple SCSs are processed separately in a shared cell, then processing simplicity is maintained, but resource waste increases and communication quality degrades
Solution Approach 1:
The patent combines multiple subcarrier spacings (SCSs) into a single eAxC ID at the middle node, allowing unified processing of uplink data from multiple RUs with different SCSs. This merging approach eliminates resource waste associated with separate processing while maintaining processing efficiency through centralized handling at the middle node.
2Productivity
If uplink data combining is performed at the middle node, then resource utilization improves, but processing delay increases
Solution Approach 1:
The middle node performs uplink data combining in advance before transmitting to the DU, consolidating data from multiple RUs with different SCSs into a single stream. This preliminary combining action improves resource utilization by enabling efficient centralized processing while the timing information mechanism ensures that the combined data is ready when needed, minimizing the impact on overall system timing.
3Reliability
If timing information is optimized for each SCS, then communication quality improves, but system complexity increases
Solution Approach 1:
The middle node is designed with multi-functionality to handle multiple SCSs (15kHz, 30kHz, 60kHz) through a single eAxC ID, receiving timing information from the controller that applies universally across different SCS configurations. This universal handling approach maintains communication quality by properly managing timing for each SCS type while avoiding the complexity of separate processing systems for each SCS.

AI summary
A method performed by a middle node in a communication system includes: receiving a request message for capability information from a controller, transmitting capability information of the middle node as a response to the request message; and receiving timing information corresponding to multiple subcarrier spacings (SCSs) from the controller based on the capability information of the middle node.
