Base Station Sidelink Resource Configuration in Connection Release Messages
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the New Radio (NR) communication system, terminals in an inactive state cannot obtain required sidelink radio resources through system information, leading to unreliable sidelink communication.
Innovation Solution
A method where a base station sets and transmits radio resource configuration information within a connection release message to terminals, enabling them to acquire necessary sidelink communication resources, even in inactive states, by including configuration details for transmitting and receiving resource pools and valid areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If terminals use system information to obtain sidelink radio resources in idle state, then resource acquisition is simple, but resource unavailability occurs in inactive state
Solution Approach 1:
The base station performs preliminary action by including sidelink resource configuration information in the connection release message before the terminal enters inactive state. This ensures the terminal has the necessary resource information readily available when needing to perform sidelink communication, eliminating the resource unavailability issue without complicating the resource acquisition process.
2Reliability
If base station transmits resource configuration through connection release message, then resource availability is improved in inactive state, but message complexity increases
Solution Approach 1:
The patent merges the sidelink resource configuration information with the existing connection release message structure. By combining these two elements into a single message transmission, the base station improves resource availability in inactive state while avoiding the complexity of introducing a separate, standalone configuration message mechanism.

AI summary
The present disclosure provides a resource configuration method and an apparatus. The method is applied to a base station, including: setting radio resource configuration information used for sidelink communication for a terminal; when determining that it is required to transmit a connection release message to the terminal, adding the radio resource configuration information to the connection release message; and transmitting the connection release message to the terminal, so that the terminal acquires the radio resource configuration information from the connection release message and performs sidelink communication according to the radio resource configuration information.
