Provided are a method and a device for setting a repetition level of a random access preamble and determining transmission power for each random access preamble, when a random access preamble for an MTC terminal is repetitively transmitted and received to increase the transmission and reception performance of a random access preamble for a coverage-restricted MTC terminal. Provided are also a method and a device for controlling transmission power for a random access preamble when a terminal, located in improved coverage compared to the coverage for a general terminal, repetitively transmits the random access preamble. When the terminal repetitively transmits a PRACH through a plurality of uplink subframes, the terminal can determine the repetition number of transmitting the PRACH, determine transmission power for the PRACH based on the determined repetition number, and transmit the PRACH at the transmission power determined for the PRACH.
A method of performing a random access by a terminal, the method comprising:
A terminal for performing random access, the terminal comprising:
A method of transmitting, by a terminal, a random access preamble through a random access channel (Physical Random Access Channel, PRACH), the method comprising:
