摘要： A method and apparatus for determining a vertical beam for reception are disclosed herein. A method in a wireless transmit/receive unit (WTRU) includes that the WTRU may receive a broadcast message from an evolved Node B (eNB) that includes information associated with a plurality of beam reference signals, wherein the information includes at least one set of Physical Random Access Control Channel (PRACH) resources associated with each of the plurality of beam reference signals. Further, the WTRU may measure reference signals transmitted on each of the plurality of beam reference signals. Then, the WTRU may select a beam reference signal from among the plurality of beam reference signals. In addition, the WTRU may transmit a PRACH preamble in a set of resources associated with the selected beam reference signal. The WTRU may then receive further communications from the eNB.

摘要： 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.

摘要： A method and apparatus for power control for wireless transmissions on multiple component carriers corresponding to multiple serving cells associated with multiple timing advances are disclosed. A wireless transmit/receive unit (WTRU) may determine transmit powers for a first physical channel for a first serving cell in a first timing advanced group (TAG) and a second physical channel for a second serving cell in a second TAG. The first TAG may less timing advanced than the second TAG. The WTRU may determine a WTRU configured maximum output power (PCMAX) for an overlapping portion, which may be a portion of a transmission of the first channel in a first subframe that overlaps in time with a portion of a transmission of the second channel in a next subframe. The WTRU may adjust the channels such that a sum of their transmit powers in the overlapping portion does not exceed the determined PCMAX.

摘要： Techniques for performing inter-frequency and/or inter-radio access technology (RAT) measurements are disclosed. A multi-receiver wireless transmit/receive unit (WTRU) may receive downlink transmissions via a plurality of downlink carriers simultaneously. The WTRU may perform inter-frequency and/or inter-RAT measurements using an inactive receiver without measurement gaps if at least one receiver is inactive. If the WTRU receives a measurement order on a disabled carrier, the WTRU may perform measurements on the disabled carrier without measurement gaps using an inactive receiver while maintaining a status of the disabled carrier as disabled. The WTRU may perform the measurements autonomously if a trigger condition is met and at least one receiver is inactive. If all receivers are active, the WTRU may perform the measurements using measurement gaps, that may be configured on a downlink carrier, or alternatively, on an unpaired downlink carrier, or alternatively, on a subset of associated downlink uplink carrier pairs.
