1. A terminal in a wireless communication system, the terminal comprising:
at least one transceiver; and
a controller coupled with the at least one transceiver,
and configured to:
determine a first beam as a serving beam of the terminal based on channel qualities of a plurality of beams of the terminal,
obtain synchronization information of the first beam of the terminal,
obtain a first difference between a previous cell time of a second beam of the terminal and a current cell time of the second beam, wherein the second beam is different from the first beam,
obtain new synchronization information of the serving beam according to the first difference,
obtain at least one channel quality of the plurality of beams based on the new synchronization information, and
update the serving beam based on the obtained at least one channel quality.
