Abstract: A method may comprise transmitting using a first uplink carrier and receiving a signal using a first downlink carrier. The signal may include a message indicating activation of a second uplink carrier. A method may further comprise initiating, based on the message, a timer associated with deactivation of the second uplink carrier. The method may further comprise transmitting using the second uplink carrier activated based on the message and deactivating the second uplink carrier on a condition that expiration of the timer is detected.

Abstract: Methods and systems for transmitting uplink control information and feedback are disclosed for carrier aggregation systems. A user equipment device may be configured to transmit uplink control information and other feedback for several downlink component carriers using one or more uplink component carriers. The user equipment device may be configured to transmit such data using a physical uplink control channel rather than a physical uplink shared channel. The user equipment device may be configured to determine the uplink control information and feedback data that is to be transmitted, the physical uplink control channel resources to be used to transmit the uplink control information and feedback data, and how the uplink control information and feedback data may be transmitted over the physical uplink control channel.

Abstract: A wireless transmit/receive unit (WTRU) may operate in a first state where the WTRU does not have configured physical channels and discontinuously monitors for pages and a second state where the WTRU has configured uplink physical channels. The WTRU may, in response to a signal, transition to the first state and store an identity and medium access control (MAC) information. The WTRU may reinitiate communication with a network using the stored identity and MAC information.

Abstract: A first message may be received on a first carrier and communication initiated using a second carrier based on the received first message. Communication may continue on the first carrier such that the first carrier and the second carrier have different radio network terminal identifiers (RNTIs) and the first and second carrier have discontinuous reception cycles with different times of discontinuous reception. The discontinuous reception of the first carrier may be ceased based on a second message and the discontinuous reception of the second carrier may be ceased based on the third message.

Abstract: Systems, methods, and instrumentalities to optimize procedures relating to machine type communication devices. Individual UEs may be grouped together in order to optimize procedures relating to members of the group. For example, a group of UE devices may be predefined or a group may be configured by a network associated with the UEs. One or more of the members of the group may be designated as a special UE or a master UE. The special UE or master UE may perform an action on behalf of one or more members of the group.

Abstract: Disclosed herein are embodiments for Machine Type Communication (MTC). The techniques disclosed may reduce signaling by transmitting MTC data over control planes and avoiding a full cycle of connection procedures typically required for transmission. MTC data may be directly appended to a control plane message. In addition, in order to reduce the signaling load, a WTRU may autonomously release the connection without being told by the network. Techniques may be used to indicate a network provider's machine type communication (MTC) capability. The MTC services or capabilities that may be provided by a respective network operator may be communicated to a WTRU.

Abstract: Methods and apparatus for mitigating in-device interference are described. The methods may include an in-device interference event (e.g. an interference situation), and the processing of events may depend on the priority of the technologies. A handover to another frequency or radio access technology (RAT) may occur in case a co-existing technology may be activated. The network may signal to the device a list of frequencies or RATs that it may be allowed to measure and handoff to. A network may provide a scaling value that the device may use to speed up reaction to the interference. The device may apply a scaling factor to an “out of synch’ counter and/or the radio link failure (RLF) tinier used for the RLF procedure. The device may apply different scaling factors for the measurements and time to trigger events. The device may trigger a report to the network requesting gaps for an alternate RAT.

Abstract: A method and apparatus for supporting machine-type communications (MTC) are disclosed. A wireless transmit/receive unit (WTRU) may configure itself to operate in a mobile-originated-only mode. The WTRU may perform no, or a subset of, radio resource control (RRC) idle and/or non-access stratum (NAS) idle/standby state procedures in the mobile-originated-only mode. For example, the WTRU may perform cell reselection but not paging monitoring in the mobile-originated-only mode. Alternatively, the WTRU may perform paging monitoring but not cell reselection and location update. The operation in the mobile-originated-only mode may be triggered explicitly or implicitly. For example, the WTRU may operate in the mobile-originated-only mode if an inactivity timer expires. The WTRU may switch the mode in accordance with a pre-configured schedule. After transition of the operation mode, the WTRU may send a message to the network indicating such mode switch.
