MT-SDT Resource Configuration for Reduced Small Data Waste
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing mobile terminate small data transmission (MT-SDT) procedure wastes resources when using the same resources configured for mobile original small data transmission (MO-SDT) due to full reuse of these resources.
Innovation Solution
The method involves configuring a first configuration resource for MT-SDT using CG or random access resources, which may be shared with or part of MO-SDT resources, and transmitting an RRC resume request message with an indicator to distinguish the MT-SDT procedure, optimizing resource utilization.

Engineering Contradiction Analysis
1Device complexity
If the same resources configured for MO-SDT are fully reused for MT-SDT, then the device complexity is reduced, but resource waste occurs
Solution Approach 1:
The patent segments the resource pool by introducing separate resource configurations for MT-SDT and MO-SDT procedures. The network device configures dedicated resources for MT-SDT (downlink small data transmission) while maintaining separate resource configurations for MO-SDT (uplink small data transmission), preventing resource waste through clear resource partitioning while maintaining manageable system complexity
Solution Approach 2:
The patent applies local quality by assigning different resource characteristics to different transmission directions. MT-SDT resources are specifically optimized for downlink transmission with appropriate timing and frequency allocations, while MO-SDT resources are optimized for uplink transmission, ensuring each resource type has the appropriate quality characteristics for its specific function
2Productivity
If separate resources are configured for MT-SDT, then resource utilization efficiency is improved, but device complexity increases
Solution Approach 1:
The patent implements universality by designing a unified resource configuration framework that handles both MT-SDT and MO-SDT procedures. The same base configuration structure and signaling mechanisms are used for both transmission directions, allowing the system to manage multiple functions through a single standardized interface, thereby reducing overall complexity while improving resource utilization
Solution Approach 2:
The patent applies preliminary action by pre-configuring separate resource pools for MT-SDT and MO-SDT before actual data transmission occurs. The network device establishes dedicated resource allocations in advance through RRC signaling, so that when small data transmission is needed, the appropriate pre-configured resources are immediately available without requiring complex real-time resource allocation decisions

AI summary
The present disclosure provides a small data transmission method, a terminal, a network device, an apparatus, and a storage medium. The method comprises: receiving a first configuration message sent by the network device, wherein the first configuration message is used for configuring a first configuration resource, and the first configuration resource is used for sending related information of an MT-SDT process; and when determining to trigger the MT-SDT process, sending an RRC recovery request message to the network device on the first configuration resource.
