Abstract
A method for transmitting a random access preamble using a random access procedure in a mobile communication system. The random access preamble transmission method includes selecting, upon triggering of the random access procedure, one of random access preamble sets predefined between a User Equipment (UE) and an Evolved Node B (ENB) according to whether a radio channel condition is greater than a radio channel condition threshold and a size of a message that the UE will transmit after transmission of the random access preamble is greater than a minimum message size, randomly selecting a random access preamble from the selected random access preamble set, and transmitting the selected random access preamble to the ENB over a random access channel.
