Abstract
A base station applies frequency switching transmission diversity and a precoding vector to a synchronization channel and applies a space-frequency block coding and a precoding vector to a broadcast channel. The base station controls the synchronization channel and the broadcast channel to be positioned adjacent each other and then generates and transmits a downlink frame. The base station includes partial information on the number of antennas in the synchronization channel, and other information thereon in the broadcast channel.
