Abstract: Disclosed are a measurement method and a measurement apparatus for supporting mobility in a communication system. An operation method of a terminal may comprise receiving, from a base station, control information including first information indicating one or more physical uplink shared channel (PUSCH) interlaces configured in an unlicensed band; identifying frequency resources corresponding to the one or more PUSCH interlaces; and transmitting a PUSCH to the base station using the frequency resources of the unlicensed band. Thus, the performance of the communication system can be improved.
