Dynamic Frequency Allocation for NR Resource Utilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The fixed frequency domain resource allocation type in the resource block group (RBG) form leads to low utilization in new radio (NR) systems, causing inefficiencies such as resource waste and packet interception.
Innovation Solution
A network device dynamically allocates frequency domain resources by indicating which resources to use and which to avoid using, allowing flexible resource allocation through methods like puncturing and bandwidth part switching, and power allocation adjustments.

Engineering Contradiction Analysis
1Ease of manufacture
If frequency domain resources are allocated in a fixed RBG form, then the allocation process is simple, but the frequency domain resource utilization is low
Solution Approach 1:
The patent transforms the fixed RBG allocation form into a dynamic allocation mechanism where the network device can flexibly indicate different resource sets and configurations. The terminal can dynamically switch between different allocation types (RBG form and RB form) based on actual needs, making the allocation process adaptive rather than static, thereby improving resource utilization while maintaining operational simplicity.
Solution Approach 2:
The patent changes the allocation parameters by introducing indication information that specifies different resource configurations (first resource set with first configuration, second resource set with second configuration). This allows the system to vary allocation parameters dynamically, enabling better resource matching with actual terminal requirements and reducing waste.
2Device complexity
If a fixed RBG form allocation is used, then the system complexity is low, but the adaptability to different terminal needs is poor
Solution Approach 1:
The system maintains relatively low complexity by using indication information mechanisms rather than completely redesigning the allocation framework. The terminal can dynamically adapt to different needs by receiving indication information about resource sets and configurations, providing versatility without requiring fundamental system complexity changes.
Solution Approach 2:
The patent makes the allocation system universal by enabling the network device to allocate resources in multiple forms (RBG form and RB form) and the terminal to handle multiple allocation types. This multi-functionality allows a single allocation mechanism to serve different terminal needs and scenarios, improving adaptability while maintaining system-wide compatibility.
3Loss of energy
If frequency domain resources are dynamically allocated based on actual needs, then the resource utilization is improved, but the indication information overhead increases
Solution Approach 1:
The patent applies local quality by providing different allocation configurations only where needed. The network device indicates specific resource sets and configurations based on actual terminal requirements, rather than universally applying the same allocation structure to all terminals. This targeted approach reduces unnecessary information overhead while maintaining high resource utilization for active allocations.
Data Source
AI summary
This application provides a resource allocation method and apparatus, and belongs to the field of communication technologies, to improve frequency domain resource utilization. In the method, when a network device reserves, for a first terminal, a frequency domain resource set that can be used by the terminal, the network device may indicate, by using first information, the first terminal to use a part of frequency domain resources in the frequency domain resource set, for example, indicate the first terminal to use only a first frequency domain resource to perform data transmission. In this way, data transmission of a plurality of terminals is completed by using a frequency domain resource set of one terminal, and frequency domain resource utilization is improved. In addition, the terminal can implement TTI-level resource allocation type switching, so that a resource allocation type of the terminal can be adjusted and matched in real time.
