Paging Message Early Data Transmission in 5G IoT
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G communication systems face challenges in efficiently transmitting or receiving short data without switching a user equipment (UE) from an idle or inactive mode to a connected mode.
Innovation Solution
The proposed method involves using a paging message or random access to transmit or receive short data, allowing a UE in idle or inactive mode to perform downlink early data transmission (DL EDT) without switching to a connected mode, by utilizing dedicated preambles and specific RRC messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a UE in idle or inactive mode switches to connected mode for data transmission, then data transmission capability is improved, but signaling overhead and power consumption increase
Solution Approach 1:
The patent segments the data transmission process by allowing the UE to remain in idle or inactive mode for short data transmissions, separating the signaling process into minimal essential steps (paging message reception, dedicated preamble transmission) while avoiding full connection establishment. This segmentation enables data transmission without complete mode switching, reducing signaling overhead while maintaining transmission capability.
Solution Approach 2:
The base station performs preliminary action by including a dedicated preamble in the paging message before the UE needs to transmit data. This pre-configured preamble allows the UE to immediately respond with data transmission capabilities without going through the full connection establishment process, thereby reducing signaling overhead while ensuring transmission reliability.
2Reliability
If a UE in idle or inactive mode switches to connected mode for data transmission, then data transmission capability is improved, but transmission time increases
Solution Approach 1:
The base station performs preliminary action by including a dedicated preamble in the paging message before the UE needs to transmit data. This pre-configured preamble allows the UE to immediately respond with data transmission capabilities without going through the full connection establishment process, thereby reducing signaling overhead while ensuring transmission reliability.
Solution Approach 2:
The patent applies skipping by allowing the UE to skip the intermediate connected mode establishment steps and proceed directly from idle/inactive mode to data transmission using the dedicated preamble. This rushing through of essential steps reduces transmission time while maintaining the necessary reliability for data transmission.
