    Abstract: Systems, methods and instrumentalities are provided to implement a mechanism of a secondary user (SU) system coexisting with a primary user (PU) system. The SU system may gather information associated with the operation cycle(s) of the PU system of a shared channel. An operation cycle of the PU system may include a quiet phase and a pulse phase. For example the SU system may gather information associated with the operation cycle of the PU system. Such information may include pulse phase duration, pulse duty cycle, and/or allowed hopping sequences, etc. Based on information associated with the operation cycle of the PU system, the SU system may transmit or schedule transmission on the shared channel during the quiet phase of the PU operation cycle. The SU system may perform interference mitigation based on the timing of the pulse phase.

    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) timer 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 determining a vertical beam for reception are disclosed herein. A method in a wireless transmit/receive unit (WTRU) includes receiving a broadcast message from an evolved Node B (eNB) that includes information associated with a plurality of vertical beams, wherein the information includes at least one set of Physical Random Access Control Channel (PRACH) resources associated with each of the plurality of vertical beams, measuring reference signals transmitted on each of the plurality of vertical beams to select a reception vertical beam, transmitting a PRACH preamble in a set of resources associated with the selected reception vertical beam, and receiving communications from the eNB using the selected reception vertical beam.

    Abstract: Half duplex (HD) frequency division duplexing (FDD) in a wireless transmit-receive unit (WTRU) using a single oscillator (SO) for uplink (UL) and downlink (DL), which may contribute to reduced costs of implementation. Approaches to the resolution of scheduling issues which may result from increased switching time versus implementations using separate oscillators are discussed, including indication of SO-HD-FDD capability, scheduling for collision avoidance, enhanced node-b (eNB) receiver implementations, link adaptation for missed detected physical downlink control and shared channels, collision handling, DL measurement, and burst based transmissions.
