Abstract
A terminal executes a random access procedure with a target base station depending on a pre-random access channel (pre-RACH) command in a handover preparation step executed between a source base station currently accessed by the terminal and the target base station when the terminal receives the pre-RACH command from the source base station through layer2 (L2) signaling in the handover preparation step.
