Radio Communication Node Tdelta Adaptation by SCS and Frequency Range
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The value of Tdelta, a time difference in radio communication nodes, is not always appropriate due to variations in subcarrier interval (SCS) and frequency range (FR) used in the serving cell, leading to inefficiencies in radio resource utilization and communication quality.
Innovation Solution
A radio communication node that includes an acquiring unit to determine subcarrier interval and frequency range, and a control unit to set a reference additional time (Tdelta_o) and granularity based on these parameters, allowing for appropriate Tdelta setting regardless of SCS and FR.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed Tdelta value is used in IAB node, then the configuration is simple, but the Tdelta becomes inappropriate when SCS or FR changes
Solution Approach 1:
The patent applies dynamics by making the Tdelta value adjustable rather than fixed. The control unit dynamically determines the appropriate Tdelta based on the detected SCS and FR parameters, allowing the system to adapt to different operating conditions while maintaining appropriate timing characteristics.
Solution Approach 2:
The patent changes the parameter of Tdelta based on other parameters (SCS and FR). By establishing a relationship where Tdelta is determined from SCS and FR, the system automatically adjusts the timing parameter to match the current operational context, resolving the contradiction between adaptability and complexity.
2Reliability
If Tdelta is not set appropriately according to SCS and FR, then radio resource utilization is efficient, but communication quality deteriorates
Solution Approach 1:
The patent implements feedback by having the control unit detect the actual SCS and FR parameters from the serving cell and use this information to determine the appropriate Tdelta value. This closed-loop approach ensures that the timing parameter is continuously optimized based on real-time operational conditions, simultaneously maintaining communication quality and resource utilization efficiency.

AI summary
A radio communication node (100B) includes a cell information acquiring unit (165) that acquires a subcarrier interval to be set and a frequency range to be used; and a control unit (170) that sets a reference additional time included in a time difference from transmission in a serving cell to reception in the radio communication node and the granularity applied to the reference additional time based on the subcarrier interval and the frequency range.
