Patent ID: 7725107

Claim:
A wireless transmit/receive unit (WTRU) comprising: a selectively configurable transceiver having a connected mode defined by a plurality of functional states including: a monitoring state wherein the transceiver is configured for reception only; a duplex state wherein the transceiver is configured for both transmission and reception in which the WTRU has received a temporary identifier; and a transition state in which the WTRU is enabled to request the temporary identifier required for the duplex state wherein the transceiver is configured to send only predefined initiation communications and is otherwise configured only for reception; the transceiver configured to transition from the monitoring state into the transition state upon occurrence of predefined WTRU events that are each associated with a respective initiation communication of a predefined procedure where at least one procedure requests a response that includes the temporary identifier; and the transceiver configured to transition from the transition state into the duplex state after receiving a response with the requested temporary identifier.
