Abstract: A drifting wireless transmit/receive unit (WTRU) has an associated drift radio network controller (D-RNC) and an associated servicing radio network controller (S-RNC). The D-RNC sends a request message to the S-RNC requesting measurements of the drifting WTRU. The S-RNC receives the request message and sends an information message with the requested measurements to the D-RNC. The D-RNC receives the information message.

Abstract: A wireless communication system having a Node B and a plurality of wireless transmit/receive units (WTRUs), includes a contention-based uplink (UL) channel and at least one downlink (DL) physical channel. The UL channel supports UL transmissions from the WTRUs to the Node B. The UL channel is randomly accessed by a WTRU when the WTRU is ready to transmit data. The DL physical channel supports DL transmissions from the Node B to the WTRUs. The DL transmissions include an acquisition indicator and information regarding said acquisition indicator. The acquisition indicator confirms whether the data transmitted over said UL channel was successfully received by the Node B.

Abstract: A method for improving the reliability of a channel quality indicator (CQI) message in a wireless communications network begins with receipt of the CQI message. The CQI message is then decoded, and a decision metric value for each symbol in the CQI message is computed. A largest decision metric value and a second largest decision metric value for the CQI message are determined. The reliability of the CQI message can be determined by comparing the two largest decision metric values. This method may be applicable to high-speed downlink packet access in time division duplex, frequency division duplex, or other modes of transmission.

Abstract: A method for handover a mobile unit from a first base station to a second base station in a wireless communication systems employing smart antenna technology. Following trigger events of a handover, the mobile station generates a physical signal sounding pulse transmitted by an isotropic antenna. The sounding pulse may consist of a common sequence of symbols or a specific sequence of symbols that uniquely identifies the mobile station. A series of sounding pulses can be sent according to a power ramping procedure until a base station has focused a communications beam toward the mobile. Receiving base stations provide feedback information upon detection of the sounding pulse allowing the mobile unit and/or base station to form communication beams toward each other. A mapping protocol may also be utilized by the communication system.
