摘要： A method performed by a terminal for aligning uplink synchronization in wireless communication system, includes: obtaining a difference value between: first downlink synchronization based on a synchronization signal/physical broadcast channel (SS/PBCH) block corresponding a first beam and second downlink synchronization based on the SS/PBCH block corresponding a second beam; based on a comparison between the second downlink synchronization and cyclic prefix (CP) length, transmitting, to a base station, reporting information comprising information associated with the difference value; and receiving, from the base station, information on a timing advance (TA) value derived based on the information associated with the difference value.
