Classification: CPC H | IPC H

Claim 10:
11. A method for performing, by a base station, handover of a user device in a wireless communication system, the method comprising:
transmitting a dual active protocol stack (DAPS) handover request to the user device operating based on a full duplex radio (FDR) mode;
forwarding buffered data of the user device to a target cell based on the DAPS handover request; and
receiving a handover success message from the target cell,
wherein the user device operates based on at least one of the FDR mode and a half duplex radio (HDR) mode,
wherein, based on a DAPS handover procedure that the user device performs for handover from a source cell to the target cell, the user device maintains an enabled status for the source cell until the user device is connected to the target cell, and
wherein, in case that the user device transmits first data to the source cell and receives second data from the target cell during the DAPS handover procedure, based on an overlap being present between a time resource of the first data transmitted to the source cell and a time resource of the second data received from the target cell, the user device performs a self interference cancellation (SIC) based on transmission of the first data and reception of the second data and feeds an SIC result back to the target cell.
