Abstract
A method and apparatus for allocating resources to a wireless transmit receive unit (WTRU) includes the WTRU transmitting a signature sequence to a Node B, receiving an acknowledge signal from the Node B, and determining a default resource index. The resource index is associated with enhanced dedicated channel (E-DCH) parameters.
Claims20
A method implemented by a wireless transmit receive unit (WTRU), the method comprising:
- receiving system information, the system information indicating associations between uplink resources usable for uplink data transmission and random access channel preamble signature sequences;
- transmitting a random access channel preamble via a first random access channel resource;
- determining an uplink resource from the uplink resources usable for uplink data transmission based on the random access channel preamble and based on an association of the uplink resource with a random access channel preamble signature sequence of the random access channel preamble;
- and
- transmitting an uplink data transmission via the uplink resource.

A wireless transmit receive unit (WTRU) comprising:
- a transceiver;
- and
- a processor configured to:
- receive system information indicating associations between uplink resources usable for uplink data transmission and random access channel preamble signature sequences;
- transmit a random access channel preamble via a first random access channel resource;
- determine an uplink resource from the uplink resource usable for an uplink data transmission based on the random access channel preamble and based on an association of the uplink resource with a random access channel preamble signature sequence of the ransom access channel preamble;
- and
- transmit an uplink data transmission via the uplink resource.
