Wireless transmit receive unit having a transition state for transitioning from monitoring to duplex connected states and method
Abstract
A wireless transmit/receive unit (WTRU) and method for wireless uplink communication to and downlink communication from a wireless network are provided. The WTRU has a selectively configurable transceiver that has a network connected mode defined by a plurality of functional states including at least one monitoring state and a duplex state. The transceiver is configured to transition from a monitoring state upon occurrence of predefined WTRU events that are each associated with a respective uplink procedure initiation communication where at least one of procedures results in a network response that includes a temporary identifier. The transceiver is configurable into a transition state wherein the transceiver is configured to send only the uplink initiation communications and is otherwise configured only for downlink communications.
