Resource Block Group Sizing in Wireless Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In next-generation wireless communication systems, there is an ambiguity in resource allocation between base stations and user equipment (UEs), particularly in determining the size of resource allocation units like resource block groups (RBGs), which affects efficient resource allocation and multiplexing across different UEs.
Innovation Solution
A method is proposed to determine the size of RBGs efficiently, allowing for flexible resource allocation by using a bitmap scheme where each bit indicates an RBG instead of a resource block, and enabling dynamic adjustment of RBG sizes based on the system bandwidth, thereby facilitating efficient resource allocation and multiplexing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If resource allocation is performed using traditional methods without standardized RBG size definition, then flexibility in allocation is maintained, but ambiguity and inefficiency arise in resource allocation between base station and UE
Solution Approach 1:
The patent applies parameter changes by dynamically adjusting the RBG size based on system bandwidth conditions. The RBG size is defined as a function of the system bandwidth, changing from a fixed value to a variable parameter that adapts to different network scenarios. This resolves the ambiguity by establishing a clear, standardized relationship between system bandwidth and RBG size, thereby improving resource allocation efficiency while eliminating information loss.
2Ease of manufacture
If fixed RBG size is used for resource allocation, then implementation is simplified, but adaptability to different bandwidth conditions is reduced
Solution Approach 1:
The patent implements dynamics by transitioning from a static, fixed RBG size to a dynamic RBG size that varies with system bandwidth. The RBG size is determined based on the actual bandwidth conditions, allowing the system to adapt automatically to different network scenarios. This maintains implementation simplicity through a clear definition formula while significantly improving adaptability to different bandwidth conditions.
3Adaptability or versatility
If resource allocation units are not clearly defined, then system flexibility is preserved, but multiplexing performance for different UEs deteriorates
Solution Approach 1:
The patent applies parameter changes by establishing a standardized RBG size parameter that varies with system bandwidth. This clear parameter definition enables efficient multiplexing performance while maintaining system flexibility. The standardized parameter allows for better resource management across multiple UEs without sacrificing adaptability.

AI summary
Provided are a signaling method of a device in a wireless communication system and a device using same. The method comprises: transmitting, to a terminal via an upper layer signal, first information informing about a first resource unit used for interleaving; and performing interleaving for a particular resource for the terminal by the first resource unit, wherein the information informing about the first resource unit is signaled to the terminal separately from second information for informing about a second resource unit used when a base station allocates resources for the terminal.
