UE TBS Selection for Low-Padding Early Data Transmission
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless telecommunications systems face inefficiencies in handling small data transmissions during Early Data Transmission (EDT) procedures, leading to excessive resource usage and power consumption due to inadequate selection of Transport Block Size (TBS) and communication resources by user equipment (UE).
Innovation Solution
The UE determines the amount of data to transmit and selects an appropriate Transport Block Size (TBS) from a set of permitted values, along with corresponding communication resources, to minimize padding and optimize resource usage during EDT.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the UE uses the maximum TBS allocated by the network for all small data transmissions, then the resource allocation is simplified and guaranteed, but excessive padding is introduced and resource efficiency deteriorates
Solution Approach 1:
The patent applies dynamics by enabling the UE to dynamically select from multiple permitted TBS values based on the actual data amount, rather than using a fixed maximum TBS. This allows the TBS to adapt to different transmission scenarios, reducing padding for small data while maintaining simplicity through pre-defined permitted values.
Solution Approach 2:
The patent changes the TBS parameter from a fixed maximum value to a selectable value from multiple permitted TBS values. The UE determines the appropriate TBS based on the data amount and selects from permitted values, thereby optimizing resource usage and reducing unnecessary padding transmission.
2Productivity
If the UE selects a smaller TBS to match the actual data amount, then resource efficiency improves and padding is reduced, but the complexity of TBS selection and resource determination increases
Solution Approach 1:
The patent applies preliminary action by pre-defining a set of permitted TBS values that the UE can select from. This preparation eliminates the need for complex real-time calculations during transmission, as the UE only needs to select from pre-established permitted values based on its data amount.
Solution Approach 2:
The patent uses partial action by allowing the UE to select only the necessary TBS from the permitted set that matches its actual data amount, rather than always using the maximum allocated TBS. This partial utilization of available resources optimizes efficiency without requiring full complexity of resource management.
3Ease of manufacture
If the network allocates resources based on maximum TBS, then resource allocation is straightforward, but resource waste occurs for small data transmissions
Solution Approach 1:
The patent introduces dynamics into resource allocation by allowing the UE to dynamically indicate its selected TBS from permitted values. The network then allocates resources based on this indication rather than always allocating for maximum TBS, thereby reducing resource waste while maintaining allocation simplicity through the indication mechanism.
4Reliability
If the UE transmits with maximum TBS to ensure sufficient resources, then resource sufficiency is guaranteed, but transmission overhead increases and efficiency decreases
Solution Approach 1:
The patent changes the TBS parameter from a fixed maximum to a selectable value from permitted TBS values. The UE selects the appropriate TBS that matches its data amount, ensuring sufficient resources are allocated while avoiding the overhead of transmitting unnecessary padding, thereby improving transmission efficiency.
