Classification: CPC H | IPC H

Claim 3:
4. A terminal for performing initial beam alignment during a random access procedure, the terminal comprising:
a transceiver; and
a processor coupled with the transceiver and configured to control to:
control the transceiver to transmit, on a serving cell, a measurement report message including beam measurement information associated with a target cell, in response to a measurement reporting event triggered,
control the transceiver to receive, on the serving cell, a handover command message including a resource configuration of channel state information reference signals (CSI-RSs) associated with the target cell for an initial access beam alignment,
perform downlink (DL) synchronization with the target cell on synchronization signal (SS) blocks, and
control the transceiver to transmit, on the target cell, a random access preamble corresponding to a CSI-RS which is selected from the CSI-RSs by measuring a subset of the CSI-RSs transmitted on the target cell, the selected CSI-RS corresponding to a best beam of the target cell.
