MT-SDT Paging for Inactive UE Reception Without Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless network technologies require inactive UEs to transition to a connected state for downlink data reception, leading to increased power consumption and latency for small-data transmissions.
Innovation Solution
Implementing mobile-terminated small-data transmission (MT-SDT) procedures that allow UEs to receive downlink data in an inactive state without transitioning to a connected state, using UE-specific triggers and optimized paging mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If inactive UEs transition to connected state for downlink data reception, then reliable data delivery is achieved, but power consumption increases
Solution Approach 1:
The patent segments the data transmission process into two distinct procedures: traditional connected-state transmission for large data volumes, and mobile-terminated small data transmission (MT-SDT) for small data volumes. This segmentation allows UEs to remain in inactive state for small data transmissions, avoiding the need to transition to connected state and thereby reducing power consumption while maintaining reliable data delivery through the optimized MT-SDT procedure
2Reliability
If inactive UEs transition to connected state for downlink data reception, then data delivery is ensured, but latency increases
Solution Approach 1:
The patent implements preliminary action by pre-configuring MT-SDT parameters and maintaining UE context in inactive state, enabling the UE to receive small data transmissions without undergoing full connection establishment procedures. The network pre-establishes the necessary signaling framework and resource allocation for MT-SDT, allowing the UE to transition directly to data reception in inactive state, thereby reducing latency while ensuring data delivery
3Use of energy by moving object
If MT-SDT procedure is implemented, then power consumption is reduced, but network complexity increases
Solution Approach 1:
The patent applies universality by designing the MT-SDT procedure to handle multiple scenarios within a unified framework: the same procedure supports both mobile-terminated and mobile-originated small data transmissions, works across different network configurations, and can be applied to various data volume thresholds. This multi-functional design reduces overall network complexity by consolidating multiple specialized procedures into a single versatile MT-SDT mechanism that handles diverse transmission needs
