Abstract: The present invention provides a radio network controller (RNC) comprising a high-speed downlink packet access allocation (HSDPA) controller configured to allocate at least one high-speed shared control channel (HS-SCCH) monitored by a wireless transmit/receive unit (WTRU) in a single timeslot. The present invention provides also a WTRU comprising a receiver configured to receive at least one HS-SCCH in a single timeslot and a method for maximizing the battery efficiency of the WTRU. The method comprises receiving at least one HS-SCCH in a single timeslot, monitoring the single timeslot for the at least one HS-SCCH, and turning off power to radio frequency, RF, components of the WTRU during timeslots not being monitored for HS-SCCHs or other communication channels.

Abstract: An interference signal code power (ISCP) measurement is estimated in a time division multiple access/code division multiple access communication system. Signals transmitted in a particular time slot are received. A power level of the transmitted received signals of the particular time slot is measured. An association of ISCP values with measured power levels is provided. The measured power level is used to estimate an ISCP value.

Abstract: A method for handover a mobile unit (UE) from a first base station (BS1) to a second base station (BS2) 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 (UE) and/or base station (BS1-BS4) to form communication beams toward each other. A mapping protocol may also be utilized by the communication system.

Abstract: A method and apparatus for managing radio resources in one or more wireless communication networks. At least one radio resource manager (RRM) is provided within a network node, or as an independent entity. The RRM monitors performance on wireless communication links of the network(s) and interacts with nodes associated with those links to change the configuration on a particular wireless communication link if its performance (i.e., quality) falls below an established threshold. Information regarding current resource usage of the network is sent to the RRM by the nodes. Each of the nodes may send a quality report to the RRM including wireless communication link quality measurements and performance statistics. Alternatively, the RRM may perform the wireless communication link quality measurements. The RRM facilitates the broadcasting of information regarding current resource usage of one network to other networks to avoid collisions and interference.

Abstract: A wireless local area network (WLAN) includes a station (706), an access point (AP 702), and a network management entity (NME 704). A method for remote radio resource management in the WLAN begins by configuring a trigger condition at the AP(702). A determination is made whether the trigger condition has been met, and a notification message is sent from the AP (702) to the NME (704) if the trigger condition has been met.

Abstract: A device for identifying an emergency call in a wireless local area network includes an indicator to identify a call as an emergency call. The indicator can be a bit flag or an information element. The information element can include location information regarding the location of the station that placed the emergency call. This information can be used to locate the caller. The location information can be transmitted from the station to an access point separately from an emergency call.

Abstract: A method for creating sub-networks in a wireless mesh network begins by determining whether a trigger condition for creating a sub-network exists. Nodes in the mesh network are selected to create the sub-network if the trigger condition exists. The sub-network is then created with the selected nodes. A node for use in a wireless mesh network includes a state device for maintaining a state of the node, the state of the node relating to activity occurring at the node; an attachment list communicating with the state device; a trigger device communicating with the state device; and an attachment device communicating with the attachment list and the trigger device
