Patent ID: 8867455

Claim:
A method for wireless communication, comprising: selecting a signature from a first set of signatures available for random access for an enhanced uplink, the first set of signatures being different from a second set of signatures available for random access with a random access channel, and the first set of signatures and the second set of signatures indicating temporary identities of a plurality of user equipment (UE); generating, at one of the plurality of UEs, an access preamble based on the selected signature; sending the access preamble from the UE for random access; receiving from a Node B a message corresponding to the access preamble, the message comprising resources allocated to the UE, the allocated resources including enhanced dedicated channel (E-DCH) resources and being selected by the Node B from a pool of resources pre-allocated to the Node B and available for allocation by the Node B to UEs; sending information to the Node B using the allocated resources; operating in a CELL_FACH state prior to sending the access preamble and also while sending the information using the allocated resources; transitioning from the CELL_FACH state to a CELL_DCH state; and continuing to use the allocated resources after transitioning to the CELL_DCH state or receiving an allocation of new resources for use in the CELL_DCH state.
