Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication technologies face challenges in effectively coordinating resource granularity between different types of cells in integrated access and backhaul nodes, particularly in multiplexing modes like FDM, SDM, or full-duplex, leading to inefficient resource scheduling.
Innovation Solution
A resource configuration method and device that involves receiving and configuring resource block sets based on specific parameters, ensuring that the frequency domain resources of one cell type are greater than or equal to those of another cell type, with parameters such as bandwidth parts and subcarrier spacing being aligned to optimize resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If resource block sets are configured independently for MT cell and DU cell, then configuration flexibility is improved, but resource scheduling efficiency deteriorates due to uncoordinated resource granularity
Solution Approach 1:
The patent merges the resource configuration of MT cell and DU cell by introducing a unified resource block set configuration mechanism. The network side device configures resource block sets for both cell types simultaneously, ensuring coordinated resource granularity across the IAB node. This unified approach allows the MT and DU to operate with compatible resource frameworks, resolving the contradiction between independent configuration flexibility and coordinated scheduling efficiency.
Solution Approach 2:
The patent applies parameter changes by dynamically adjusting resource block set parameters (such as number of resource blocks, subcarrier spacing) based on the selected multiplexing mode. When FDM, SDM, or full-duplex modes are activated, the system modifies resource configuration parameters to maintain proper granularity coordination between MT and DU cells, thereby improving scheduling efficiency while preserving configuration flexibility.
2Adaptability or versatility
If different multiplexing modes (FDM, SDM, full-duplex) are supported, then system versatility is improved, but resource coordination complexity increases
Solution Approach 1:
The patent implements dynamics by making the resource configuration adaptable to different multiplexing modes. The system dynamically selects and applies appropriate resource block set configurations based on the activated multiplexing mode (FDM, SDM, or full-duplex). This dynamic adjustment mechanism allows the IAB node to handle multiple multiplexing scenarios without requiring separate static configurations for each mode, thereby reducing overall coordination complexity while maintaining versatility.
Solution Approach 2:
The patent applies universality by designing a unified resource configuration framework that can serve multiple multiplexing modes simultaneously. The network side device uses a single configuration mechanism that works across FDM, SDM, and full-duplex modes, eliminating the need for mode-specific resource coordination procedures. This universal approach simplifies the system while supporting diverse multiplexing capabilities.
3Measurement precision
If resource block set parameter is set to be greater than or equal to BWP parameter, then resource scheduling precision is improved, but configuration flexibility deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-establishing the relationship between resource block set parameters and BWP parameters during the configuration phase. The network side device preliminarily determines that the resource block set parameter should be greater than or equal to the BWP parameter to ensure proper resource granularity. This preliminary setting ensures that when resource scheduling occurs, the precision requirement is already met through the pre-configured parameter relationship, reducing the need for complex real-time adjustments while maintaining configuration flexibility.
