FIELD: radio engineering, communication.
SUBSTANCE: invention provides an improved method and a device for controlling mobile terminal power for simplifying the random access procedure in a mobile communication system based on a distributed antenna system. The method includes receiving, by a terminal, system information from a base station, wherein the system information includes transmission power information for transmitting a random access preamble; calculating transmission power using the transmission power information and transmitting the a random access preamble using the calculated transmission power.
EFFECT: low power consumption and interference.
