Abstract
An apparatus and method for providing random access signaling in a multiple input multiple output (MIMO) wireless communication system are provided. The apparatus and method determine a random access transmission scheme for the MIMO communication system based at least in part on a number of transmit antennas in the system. The random access signals are transmitted in a random access channel using the random access transmission scheme. Power control for the random access channel is performed based at least in part on the random access transmission scheme.
