Abstract: The present disclosure relates to a communication scheme for convergence of 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 an intelligent service (for example, a smart phone, 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. The present invention proposes a method and an apparatus for minimizing an uplink interference and avoiding unnecessary transmission power consumption of a terminal, by defining a method for setting uplink transmission power of the terminal in a mobile communication system. According to the present invention, a method for a terminal in a wireless communication system comprises the steps of: transmitting a random access preamble; receiving a random access response including a power control command; determining transmission power of uplink data on the basis of whether a beam through which the random access preamble has been transmitted is changed; and transmitting the uplink data on the basis of the transmission power.
