Mobile Communication Resource Block Division for Small Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mobile communication systems, especially in scenarios like MTC and VoIP, the allocation of radio resources as minimum units (resource blocks) can lead to resource shortages when a large number of radio terminals need to transmit small amounts of data, as existing systems are inefficient in managing and assigning these resources effectively.
Innovation Solution
A mobile communication system that configures one resource block by multiple resource elements, allowing division and assignment of these blocks to multiple radio terminals, with a predetermined division pattern, and includes a notification unit for downlink scheduling control information to manage resource allocation efficiently, reducing resource shortages and optimizing data transmission.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the minimum unit of radio resources to be assigned is one resource block, then the resource allocation is simple, but the radio resources will be in short supply when a large number of radio terminals need to transmit small amounts of data
Solution Approach 1:
The patent divides one resource block into multiple divided resource blocks (DRBs) along the frequency axis. This segmentation allows the system to allocate smaller portions of resources to individual terminals, enabling efficient resource utilization when many terminals transmit small amounts of data, thereby resolving the contradiction between resource availability and allocation simplicity.
2Quantity of substance
If one resource block is divided and assigned to multiple radio terminals, then radio resource availability increases, but the downlink scheduling control information size increases
Solution Approach 1:
The patent decides the division pattern of resource blocks beforehand and notifies it to radio terminals in advance. This preliminary action allows terminals to pre-configure their resource reception parameters, reducing the amount of scheduling control information needed during actual data transmission, thus resolving the contradiction between resource availability and control information size.
3Productivity
If the division pattern of resource blocks is decided beforehand and notified to terminals, then resource allocation efficiency improves, but the system requires additional notification mechanisms
Solution Approach 1:
The patent combines the division pattern notification with existing downlink scheduling control information transmission mechanisms. By merging the new functionality into existing communication protocols rather than creating separate notification channels, the system achieves improved resource allocation efficiency while minimizing additional system complexity.
