NR Relay Resource Configuration Multiplexing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing resource configuration methods for relay devices in LTE systems are not applicable to the new radio (NR) system, as they do not support the complex resource multiplexing required in NR, leading to inefficiencies in spectrum utilization and increased costs due to the need for dense deployment of access network devices.
Innovation Solution
A method and apparatus for configuring resources in a relay device that enables multiplexing of multiple resources, involving the use of time division duplex (TDD) resource configurations, where the DU resource configuration can be preconfigured or dynamically adjusted based on user types, ensuring compatibility with existing UE and optimizing spectrum utilization.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the LTE resource configuration method is used for relay devices, then the configuration is simple and interference is avoided, but the resource multiplexing function required by NR system is not supported
Solution Approach 1:
The patent applies dynamics by enabling the relay device to dynamically switch between different resource configuration modes (first resource configuration for access links, second resource configuration for backhaul links) based on traffic conditions and service requirements, allowing the system to adapt between simplicity and multiplexing capabilities as needed
2Productivity
If access network devices are deployed densely to improve spectrum utilization, then spectrum utilization is improved, but deployment costs increase due to optical fiber requirements
Solution Approach 1:
The patent introduces wireless relay devices as intermediary nodes that can forward traffic between user equipment and the core network without requiring direct optical fiber connections to each access network device. This wireless backhaul functionality reduces the quantity of optical fiber needed while maintaining spectrum utilization benefits of dense deployment

AI summary
This application provides a resource configuration method and apparatus, and a computer-readable storage medium. The method includes: ADU side of a first node obtains a first resource configuration and at least one second resource configuration, where the first resource configuration is used for communication with a terminal device and/or a second node, the second resource configuration is used for communication with the second node, the first node is a relay node, and the second node is a child node of the first node. The DU side of the first node communicates with the terminal device and/or the second node. In the foregoing technical solution, in addition to supporting a function of multiplexing a plurality of resources, the first node may further ensure compatibility with an existing terminal device.
