Radio Terminal Transport Block Size Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In LTE radio communication systems, existing technologies face inefficiencies in data transmission due to the lack of optimal transport block size management, leading to increased processing overhead and delays, particularly in determining the minimum guaranteed transport block size and resource allocation.
Innovation Solution
A radio terminal and base station processor configuration that forwards and generates transport blocks by performing concatenation or segmentation based on received TBS information, ensuring the transport block size is equal to or larger than the minimum guaranteed value, allowing for efficient resource allocation and reduced processing time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the transport block size is determined without a minimum guaranteed value, then resource allocation flexibility is improved, but data transmission reliability deteriorates
Solution Approach 1:
The invention introduces TBS information as a new parameter that specifies a minimum guaranteed transport block size. This parameter is transmitted from the base station to the radio terminal and used to determine the actual transport block size, ensuring it meets or exceeds the guaranteed minimum while maintaining flexibility for larger allocations when resources are available.
2Speed
If transport block size determination is performed without preliminary TBS information, then processing speed is improved, but processing load increases
Solution Approach 1:
The base station performs preliminary action by determining and transmitting TBS information before the actual data transmission occurs. This advance preparation allows the radio terminal to quickly determine the transport block size without performing complex calculations during the transmission moment, thereby reducing processing load while maintaining speed.
3Productivity
If the transport block size is dynamically adjusted without a minimum guarantee, then resource utilization is improved, but processing time increases
Solution Approach 1:
The invention uses TBS information as a fixed parameter that establishes a minimum guaranteed transport block size. This parameter enables rapid determination of the transport block size by comparing available resources against the guaranteed minimum, allowing dynamic adjustment for optimal resource utilization while avoiding time-consuming complex determination processes.
Data Source
AI summary
A radio terminal according to one embodiment comprises a processor. The processor is configured to: forward a data unit from an RLC layer to a MAC layer prior to receiving an uplink grant from a base station; receive the uplink grant for determining a predetermined transport block size from the base station; generate a transport block by performing concatenation or segmentation on the data unit according to the predetermined transport block size in the MAC layer; and transmit the generated transport block to the base station via a PHY layer. The processor is configured to receive TBS information indicating a minimum guaranteed value of a transport block size from the base station. The predetermined transport block size is a value equal to or larger than the minimum guaranteed value.
