  • Patent number: 11252611
    Abstract: The disclosure relates to a pre-5th-generation (5G) or 5G communication system to be provided for supporting higher data rates beyond 4th-generation (4G) communication system such as long term evolution (LTE). Provided are an apparatus and a method for determining a bandwidth in a wireless communication system. A method of operating a base station (BS) in a wireless communication system includes: receiving information on a bandwidth supporting capability of a terminal from the terminal; transmitting information on at least one candidate bandwidth corresponding to the bandwidth supporting capability to the terminal; and transmitting information indicating a utilization bandwidth of the terminal among the at least one candidate bandwidth to the terminal. Accordingly, it is possible to reduce power consumption of the terminal and overhead for a bandwidth indication.
