Abstract
An operation method of a terminal, for a handover in a mobile communication system, may comprise performing measurement on beams of a target base station, and transmitting a measurement result of at least one beam of the target base station to a source base station; receiving, from the source base station, a handover command message including information on at least one RACH resource for the at least one beam; transmitting a handover indication message including information on at least one random access target beam having an order of channel conditions determined based on a latest measurement to the source base station and to the target base station through the source base station; and determining an optimal beam among the at least one random access target beam, and transmitting a RACH to the target base station through a RACH resource allocated to the optimal beam.
