Idle Mode Data Transmission Using Pre-Configured Dedicated Resources
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless communication technologies face challenges in conserving energy during the transmission of small data packets, particularly in RRC idle states, due to the energy-intensive processes involved in establishing and maintaining RRC connections.
Innovation Solution
Implementing pre-configured dedicated resources for data transmission in the RRC idle mode, allowing terminals to switch directly to a data transmission state without establishing a full RRC connection, thereby reducing power consumption and optimizing energy usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a full RRC connection is established for data transmission, then communication reliability is improved, but energy consumption increases
Solution Approach 1:
The patent segments the RRC connection establishment process into two independent parts: (1) a lightweight idle mode RRC connection for basic communication, and (2) a separate data transmission phase. This allows the UE to maintain a simple idle state connection while establishing only the necessary data transmission resources when needed, reducing overall energy consumption while maintaining communication reliability.
Solution Approach 2:
The patent applies preliminary action by pre-configuring dedicated resources (time-frequency resources, physical channels) for data transmission during the idle mode RRC connection establishment. This allows the UE to have ready-to-use transmission resources without establishing a full RRC connection, thereby reducing the energy-intensive connection establishment process while ensuring reliable data transmission capability.
2Use of energy by moving object
If pre-configured dedicated resources are used for data transmission in idle mode, then energy consumption is reduced, but device complexity increases
Solution Approach 1:
The patent introduces dynamic state transitions between different operational modes (idle mode with pre-configured resources, connected mode, power-saving mode). The UE can flexibly switch between these states based on data transmission needs, allowing the system to adapt resource configuration dynamically. This dynamic approach manages complexity by only activating complex resource configurations when data transmission is required, rather than maintaining them continuously.

AI summary
Methods, systems, and devices for operation in a data transmission state in an idle mode using pre-configured dedicated resources are described. An exemplary method for wireless communication includes transmitting a first message comprising an indication of pre-configured dedicated resources for a communication between the network device and a terminal, and receiving a second message over the pre-configured dedicated resources, where a transmission of the second message by the terminal causes the terminal to switch from an idle state to a data transmission state in an idle mode. Another exemplary methods for wireless communication includes receiving a first message comprising an indication of pre-configured dedicated resources for a communication between a network device and the terminal, and switching from an idle state to a data transmission state in an idle mode upon transmitting a second message over the pre-configured dedicated resources.
