A method and apparatus for signal transmission in a random access wireless communication system

The present invention provides an apparatus and method for providing a random access signal transmission in a multiple input multiple output (MIMO) wireless communication system. The apparatus and method for at least in part be determined random access transmission scheme for the MIMO communication system according to the number of transmit antennas in the system. Using the random access transmission scheme in transmitting the random access random access channel signal. Power control is performed at least in part, the random access channel according to the random access transmission scheme.
