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