摘要:
A method and apparatus for performing non-voice emergency services (NOVES) between a wireless transmit/receive unit (WTRU) and a public safety answering point (PSAP) is disclosed. A NOVES session may be initiated by sending a NOVES initiation request message that includes information relating to the NOVES capabilities of the WTRU, and information relating to an emergency situation. The information relating to the NOVES capabilities of the WTRU may include an indication of whether the WTRU supports a fake power-off mode, or whether the WTRU supports PSAP control. Other methods are disclosed that include a method for a PSAP combining a multiple NOVES sessions, and a method for handing over a NOVES session having multiple media streams.

Methods are presented wherein a WTRU may determine, based on measurements, that it is a victim of interference from another cell such a closed subscriber group (CSG) cell. In addition, methods are presented for the UE to inform the CSG cell that UE is present and is a victim UE. Methods for informing the CSG cell may include the grant of temporary membership to a victim UE, the use of a connected WTRU as a relay, and/or indicating victim status in a control message. The indication may trigger an interference management procedure. Methods for the WTRU to stop interference management at the CSG cell, methods to allow the use of a training period by the CSG eNB to allow for non-CSG WTRUs to report their presence, and methods to indicate how to perform UE Victim Indication are also presented.
摘要:
In a wireless communication system using a reference channel used for error rate measurement and associated with a plurality of transport channels multiplexed on a coded composite transport channel (CCTrCH), a method is employed for reselection of the reference channel from favorable candidate transport channels. A channel is initially selected from the plurality of multiplexed channels as the reference channel. Channels are monitored based on quantitative data content criteria to determine whether an ON or OFF state exists. A different channel is selected from the plurality of multiplexed channels as the reselected RTrCH when a better candidate transport channel in the ON state becomes available, or when the monitored RTrCH reflects an OFF state.

Method and apparatus efficiently signal and use resources for wireless communications supporting circuit switched (CS) and packet switched sessions (PS). Signaling and interaction between the wireless transmit/receive unit (WTRU), and various network entities, such as the Mobility Management Entity (MME), the Visitor Location Register (VLR), and Base Stations (BS), are used to implement circuit switched fall back (CSFB) in a PS system.
摘要:
Methods and apparatus are described for supporting wireless transmit/receive unit (WTRU) mobility between Home (evolved) Node Bs (H(e)NBs) that are configured to communicate with a Local Gateway (L-GW). The H(e)NBs and/or L-GW may belong to one or more Local H(e)NB Networks (LHNs). A WTRU may receive services including Selected Internet Protocol (IP) Traffic Offload (SIPTO) or Local IP Access (LIPA) services from the L-GW via one or more H(e)NBs. The WTRU may continue to receive SIPTO or LIPA services after a handover to another H(e)NB that may be in communication with the same L-GW and may belong to the same LHN. The WTRU may receive information related to the LHN or the L-GW to allow continuation of SIPTO or LIPA services as the WTRU moves among H(e)NBs and/or out of the LHN. The WTRU may receive and/or maintain one or more LHN Lists.
摘要:
Methods and apparatus are described for transmitting and receiving data by a wireless transmit/receive unit (WTRU) over the control plane. The methods may receive data without the use of an Internet Protocol (IP) address. In an example method, a WTRU may enter an evolved packet system (EPS) mobility management (EMM)-registered control plane only (CPO) state after receiving an attach accepted message for CPO operation, and enter an EMM-deregistered state after receiving a detach message, a tracking area update (TAU) reject message or an attach reject message. In another method, a WTRU may switch between operational modes that use an IP address and a user plane to transmit and receive data, and the CPO mode.

A method and apparatus may be used to enable reception of a downlink (DL) shared channel in a cooperative multipoint transmission (CoMP). The method and apparatus may determine whether CoMP is applied to a transmission. The method and apparatus may acquire other CoMP related information. The method and apparatus may apply to non-transparent CoMP scenarios.
摘要:
A method and apparatus for multiple radio access technology (multi-RAT) access mode operation for a wireless transmit/receive unit (WTRU) are disclosed. A WTRU and a network may enable a multi-RAT access mode of operation based on at least one of WTRU subscription, a service agreement of the WTRU, a roaming status of the WTRU, a selected access point name (APN), an Internet protocol (IP) flow class, a subscriber profile identity for the WTRU, requested quality of service, or a proximity indication indicating proximity to a cell supporting multi-RAT access mode. The WTRU may send a capability indication of support of multi-RAT access to a network, wherein the multi-RAT access mode is enabled based on the capability indication. A partial handover of bearers may be performed. In performing the handover, the target cell is determined based on a priority rule.

摘要:
A method and apparatus for home Node-B (HNB) mobility with a local IP access (LIPA) packet data network (PDN) connection are described. A target home node-B (HNB) may receive a handover request message from a source HNB to handover a wireless transmit/receive unit (WTRU). A path switch request may be transmitted to a local gateway (LGW) to change a downlink data path towards the target HNB in response to the handover request message. The LGW may act as a mobility management and local mobility anchor for the handover; and informing an HNB gateway (GW) about the handover so that the downlink data path for core network (CN) traffic is modified towards the target HNB.
