    Abstract: The present disclosure relates to a communication scheme for combining an IoT technology and a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The present disclosure may be applied to a smart service (for example, a smart home, a smart building, a smart city, a smart car or connected car, healthcare, digital education, retail business, a security and security related service, or the like) on the basis of a 5G communication technology and an IoT related technology. A timing advance controlling method according to the present disclosure comprises the steps of: selecting a cell on the basis of a signal received from a base station; selecting one coverage class from a plurality of coverage classes in the selected cell; selecting one timing advance value from a plurality of timing advance values determined in advance on the basis of the selected coverage class; and determining an uplink transmission point on the basis of the selected timing advance value, and transmitting uplink data at the determined transmission point.

    Abstract: A method of transmitting a signal by a base station in a beam forming-based communication system is provided. The method includes: transmitting the signal using a transmission beam having at least one of a beam width and a transmission period in reverse proportion to one of a distance between a position of a transmission target region of the transmission beam for transmitting the signal within a service coverage of the base station and the base station and a size or area of the transmission target region.
