1. A method for performing a random access procedure by a user equipment (UE), the method comprising:
selecting a random access preamble;
transmitting, to a base station, the random access preamble in a first subframe;
determining a time period for receiving a random access response from the base station;
receiving the random access response from the base station within the time period; and
determining the random access response is a response to the random access preamble based on the information generated using the subframe number of the first subframe,
wherein the time period starts at a time point after an end time of transmitting the random access preamble, the time point is obtained by adding an offset to a subframe number corresponding to the end time of transmitting the random access preamble and the offset equals three.
