Sidelink Configuration Reset for Coverage and RRC Transitions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The change in access stratum configuration for a sender terminal device when switching between different coverage scenarios or RRC states affects normal communication at the receiver terminal device, necessitating a mechanism to ensure seamless communication.
Innovation Solution
A mechanism where the second terminal device transmits a second configuration and reset configuration indication to the first terminal device, allowing it to release the first configuration and switch to the second configuration for sidelink communication, ensuring smooth communication updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the sender terminal device switches between different coverage scenarios or RRC states, then the access stratum configuration can be updated to adapt to new conditions, but normal communication at the receiver terminal device is affected
Solution Approach 1:
The receiver terminal device performs preliminary actions by determining whether configuration update indication information needs to be sent to the sender before the sender actually switches configurations. This advance preparation allows the system to coordinate configuration changes and maintain communication reliability during transitions between coverage scenarios or RRC states.
Solution Approach 2:
The mechanism implements feedback by having the receiver terminal device monitor and determine whether to send configuration update indication information based on the sender's configuration change needs. This feedback loop ensures that configuration updates are coordinated between sender and receiver, allowing adaptability while maintaining communication reliability through synchronized configuration management.
2Adaptability or versatility
If the access stratum configuration changes for the sender terminal device, then the configuration can adapt to different coverage scenarios or RRC states, but the communication normality at the receiver terminal device deteriorates
Solution Approach 1:
The configuration update indication information serves as an intermediary mechanism between the sender and receiver terminal devices. The receiver uses this intermediary to coordinate configuration changes, allowing the sender to update its access stratum configuration for different coverage scenarios or RRC states while maintaining communication continuity through synchronized configuration management.
Solution Approach 2:
The receiver terminal device performs preliminary determination of whether to send configuration update indication information before the actual configuration change occurs. This preliminary action ensures that configuration updates are coordinated in advance, maintaining communication continuity while enabling necessary configuration adaptations.

AI summary
A method for resetting configuration includes that: a first terminal device performs sidelink communication with a second terminal device using a first configuration; receives a second configuration and reset configuration indication information from the second terminal device; and releases the first configuration according to the reset configuration indication information, and performs sidelink communication with the second terminal device using the second configuration. Provided are also apparatuses for resetting configuration applied to a terminal device and a second terminal device.
