ABSTRACT:
A system and method for random access channel (RACH) capture, where user equipment (UE) transmits a series of time-spaced access preambles each having an increasing power level to Node B and terminates access preamble transmission in response to an acquisition indicator (AI) signal returned from Node B and transmits its RACH message part. A collision detection preamble (CDP) is sent immediately after the message or embedded with the message. A collision detection indicator (CDI) signal matching the CDP is transmitted from Node B to the UE identified as having the failed RACH message requesting retransmission of the message. Optionally, the relative retransmission power level is also specified to the UE along with the CDI signal.
