Abstract
A wireless transmit and receive unit (WTRU) and a method for a WTRU to establish access to a channel using random access procedure are disclosed. The method comprises receiving an indication of a first set of available signatures for a random access channel (RACH) receiving an indication of a second set of available signatures for enhanced uplink transmissions randomly selecting at the WTRU a signature from the second set of available signatures for establishing random access to an enhanced uplink and sending a preamble using the selected signature.
Furthermore a network entity and a method are disclosed. The method comprises sending a first set of available signatures reserved for random access channel (RACH) and a second set of available signatures reserved for enhanced uplink transmissions receiving a preamble from a wireless transmit and receive unit (WTRU) and determining whether the WTRU is requesting enhanced uplink transmission resources based on whether the received preamble comprises a signature in the second set of available signatures.
