UE Cell Change Resource Pool Feedback Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In communication technologies, scheduling UEs cannot allocate transmission resources to scheduled UEs located in different cells due to a lack of configuration information about the scheduled UE's cell.
Innovation Solution
The scheduled UE actively sends transmission resource pool information of the new cell to the scheduling UE when a cell change occurs, ensuring the scheduling UE acquires the necessary information to allocate resources effectively.

1Area of stationary object
If the scheduling UE and scheduled UE are located in different cells, then the communication coverage is expanded, but the scheduling UE cannot allocate transmission resources due to lack of configuration information
Solution Approach 1:
The scheduled UE sends configuration information feedback to the scheduling UE when moving between cells. This feedback mechanism ensures that the scheduling UE receives necessary configuration information about the new cell, enabling it to allocate transmission resources properly while maintaining expanded communication coverage.
Solution Approach 2:
The system pre-configures the scheduled UE with area range information before cell changes occur. This preliminary configuration allows the scheduled UE to proactively send configuration information to the scheduling UE when entering a new cell, ensuring continuous resource allocation capability without information loss.
2Productivity
If the scheduled UE actively sends transmission resource pool information when moving between cells, then resource allocation efficiency is improved, but communication overhead increases
Solution Approach 1:
The scheduled UE periodically checks whether it has moved out of a preconfigured area range and only sends configuration information when necessary (i.e., when actually moving between cells). This periodic action ensures resource allocation efficiency is improved without causing continuous communication overhead.
Solution Approach 2:
The scheduled UE autonomously detects its own cell changes and proactively sends configuration information to the scheduling UE without waiting for requests. This self-service mechanism improves resource allocation efficiency while minimizing communication overhead by only transmitting information when actually needed.

AI summary
The present invention relates to a method and apparatus for transmitting configuration information. The method comprises: when a cell change is performed, checking whether scheduled user equipment is moved out of a pre-configured area range; and when the scheduled user equipment is moved out of the pre-configured area range, sending a notification message to scheduling user equipment in a group, the notification message comprising related information that is related to sending resource pool information of the changed cell.
