  • Patent number: 10382978
    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 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.

  • Publication number: 20190238305
    Abstract: A method performed by a HD-WTRU may comprise determining that an uplink SR and/or a PRACH preamble overlaps in time with one or more subframes of a scheduled downlink shared channel transmission. When the overlap occurs, the HD-WTRU may receive the downlink shared channel transmission on the one or more subframes. The HD-WTRU may process the downlink shared channel transmission, not transmit the SR and not transmit the PRACH preamble.

  • Patent number: 10263758
    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.

  • Publication number: 20190110255
    Abstract: A method and apparatus for power control for wireless transmissions are disclosed. A wireless transmit/receive unit (WTRU) may determine a first transmit power for a first physical channel for a first serving cell in a first timing advanced group (TAG) and a second transmit power for a second physical channel for a second serving cell in a second TAG. The first TAG may be associated with a first timing advance value and the second TAG may be associated with a second timing advance value. 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 slot that overlaps in time with a portion of a transmission of the second channel in a next slot. The WTRU may adjust at least one of the first physical channel and the second physical channel.

  • Patent number: 10165481
    Abstract: A serving eNodeB and a method thereof are provided. The serving eNodeB includes a receiver configured to receive, from a wireless transmit/receive unit (WTRU), a first measurement report including a physical layer cell identity (PCI) of a target closed subscriber group (CSG) cell detected by the WTRU, a transmitter configured to, in response to the received first measurement report, to transmit a message to the WTRU indicating that the WTRU is to read system information (SI) of the target CSG cell, and a processor. The receiver is further configured to, in response to a transmission of the message, receive a second measurement report for the target CSG cell including information read from the SI, and the processor is configured to, in response to receipt of the second measurement report, add the target CSG cell to a cell list and initiate a handover of the WTRU to the target CSG cell.

  • Patent number: 10159051
    Abstract: Methods, apparatus and systems are described for a wireless transmit/receive unit (WTRU) to manage its transmission power. A power headroom report (PHR) may be triggered based on changes to backoff or the impacts of backoff. Additional backoff may be used to calculate a maximum output power of the WTRU and may be indicated by a domination indicator to network resources. The WTRU may be configured to eliminate triggers caused by virtual PHRs. Furthermore, the WTRU may be configured to respond to rapid changes to backoff.

  • Patent number: 10098070
    Abstract: 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.

  • Patent number: 9948414
    Abstract: A method for performing measurements in a device with at least two radio access technologies (RATs) is disclosed. The method may include establishing a first measurement schedule on a first RAT, and establishing a first transmission schedule for a second RAT. The method may further include changing at least one of the first measurement schedule or the first transmission schedule to prevent measurements of the first measurement schedule from occurring contemporaneously with transmissions of the first transmission schedule. Transmissions from the second RAT may interfere with measurements on the first RAT. The method may include transitioning from the first measurement mode to a second measurement mode based determining the second RAT is operating on potentially interfering frequency.

  • Patent number: 9907012
    Abstract: Disclosed herein are techniques for inhibition of allowed closed subscriber group list. According to an aspect, a method may be implemented at a wireless transmit/receive unit (WTRU). The method may include identifying a public land mobile network (PLMN) in which the WTRU is operating. Further, the method may include controlling closed group subscriber (CSG) selection based on the identified PLMN.

  • Publication number: 20170367107
    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.
