Method and apparatus for transmitting configuration information

A device for transmitting configuration information, comprising:

• a processor;
• and
• a memory for storing instructions executable by the processor;
• wherein the processor is configured to execute the instructions stored in the memory to cause the device to:
• check whether a scheduled user equipment (UE) has moved out of a preconfigured area range when a cell change is performed;
• and
• send a notification message to a scheduling UE in a same group when the scheduled UE has moved out of the preconfigured area range, wherein the scheduled UE and the scheduling UE are communicated through a sidelink, and the notification message comprises relevant information regarding transmission resource pool information of a changed cell;
• wherein the processor is configured to execute the instructions to cause the device to:
• receive, before sending the notification message to the scheduling UE in the same group, system information sent by a base station when the base station serves on a frequency used for communication between the UEs, wherein the system information comprises a cell identifier and available transmission resource pool information of the changed cell, system information area identifier information corresponding to the changed cell and radio access network (RAN) area identifier information corresponding to the changed cell, and the notification message further comprises the system information area identifier information and the RAN area identifier information.

A non-transitory computer-readable storage medium having stored thereon computer instructions that, when executed by a processor of a scheduled user equipment (UE), implement a method for transmitting configuration information, comprising:

• checking whether the scheduled UE has moved out of a preconfigured area range when performing a cell change;
• and
• sending a notification message to a scheduling UE in a same group when the scheduled UE has moved out of the preconfigured area range, wherein the scheduled UE and the scheduling UE are communicated through a sidelink, and the notification message comprises relevant information regarding transmission resource pool information of a changed cell;
• wherein before sending the notification message to the scheduling UE in the same group, the method further comprises:
• when a base station serves on a frequency used for communication between the UEs, receiving system information from the base station, wherein the system information comprises a cell identifier and available transmission resource pool information of the changed cell, system information area identifier information corresponding to the changed cell and radio access network (RAN) area identifier information corresponding to the changed cell, and the notification message further comprises the system information area identifier information and the RAN area identifier information.
