1. A method for wireless communication, comprising:

  • determining a random access transmission scheme at a user equipment (UE) for a multiple input multiple output (MIMO) communication based at least in part on a number of transmit antennas at the UE to be utilized for the MIMO communication, an identified format utilized by a random access channel, and a precoding vector that is selected based on the number of transmit antennas; and

    transmitting random access signals from the UE using the random access transmission scheme determined at the UE.
