Apparatus and method for searching target cell for handover in wireless communication system

A method for operating a mobile station in a wireless communication system, comprising:

• transmitting, to a base station, a signal comprising a first component received first and remaining components;
• receiving, from the base station, information comprising a priority of a first neighboring base station located within a threshold range with respect to a direction of a beam allocated to the mobile station;
• identifying a target base station among a plurality of neighboring base stations comprising the first neighboring base station based on the priority of the first neighboring base station;
• and
• performing a handover from the base station to the target base station,
• wherein the priority of the first neighboring base station is determined by the base station, based on a difference between a strength of the first component of the signal and a strength of a strongest component of the remaining components of the signal.

An apparatus of a base station in a wireless communication system, the apparatus comprising:

• at least one processor;
• at least one transceiver operatively coupled to the at least one processor,
• wherein the at least one transceiver is configured to:
• receive, from a mobile station, a signal comprising a first component received first and remaining components;
• transmit information comprising a priority of a first neighboring base station determined based on a difference between a strength of the first component of the signal and a strength of a strongest component of the remaining components of the signal, and
• wherein the first neighboring base station is located within a threshold range with respect to a direction of a beam allocated to the mobile station.
