Abstract: Methods and apparatus are provided for transmission and reception of common channel information in a mobile communication system using multi-antenna-based beam-forming. A number of beams to be used for transmission to a terminal is determined at a base station. The common channel information is generated corresponding to the number of beams. The common channel information is transmitted from the base station to the terminal through one of the beams.
