Apparatus and method for random access signaling in a wireless communication system |
| 摘要 |
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. |

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. |
