Abstract
A method and apparatus for supporting a random access channel (RACH)-less mobility with pre-allocated beams in a wireless communication system is provided. A user equipment (UE) receives a mobility command message which includes information on a pre-allocated UL resource for UL transmission with pre-allocated beams, synchronizes to a target cell, and performs the UL transmission to the target cell via the pre-allocated beams based on the pre-allocated UL resource for UL transmission to transmit a mobility complete message via a UL grant. If the UL transmission fails, the UE may perform RACH procedure.
