METHOD AND APPARATUS FOR RANDOM ACCESS IN WIRELESS COMMUNICATION SYSTEM

摘要

A method and apparatus are provided for transmitting a random access preamble in a wireless communication system. The method includes estimating path loss based on a downlink signal received from a base station; selecting a random access region based on the estimated path loss; determining a transmission power, based on a false alarm probability of the selected random access region; and transmitting the random access preamble to the base station, based on the determined transmission power.
