  • Patent number: 9693273
    Abstract: There is provided a method for triggering mobility measurements for a wireless device. The method is performed by a radio access network node (RANN). The RANN is configurable to transmit using a set of transmission beams. The method comprises receiving signalling from a wireless device (WD). The user traffic signalling is indicative of a current position of the WD and a performance quality metric of the WD. The method comprises, only in a case the performance quality metric fulfills a location dependent performance quality criterion, activating transmission of mobility pilot signals to the WD in at least one transmission beam in the set of transmission beams. The method comprises, thereafter, instructing the WD to perform measurements on the at least one transmission beam.

  • Patent number: 9681461
    Abstract: A method implemented in a device is disclosed for networking through signals transmitted across a shared medium network. The method starts with monitoring for a first signal on a shared medium of the shared medium network. The first signal is processed after it is received and while the first signal is being processed, a set of one or more signals is received on the shared medium. Then a set of one or more amplitude increases is determined, where each amplitude increase is from an earlier received signal to a later received signal. The set of one or more amplitude increases is compared to a threshold value and at least partially in response to the comparison, the device discards one or more signals from the first signal and the set of one or more signals.

  • Patent number: 9680581
    Abstract: Separate aperiodic channel state information (CSI) reports are handled for static subframe(s), in which the direction of signal transmission is fixed, and flexible subframe(s), in which the direction of signal transmission is variable. A method by a UE includes receiving a trigger for an aperiodic CSI report as part of an uplink (UL) grant from a radio node in a static downlink (DL) subframe, where the trigger indicates a CSI subframe set, out of at least two alternative CSI subframe sets. An aperiodic CSI measurement is performed for a CSI reference resource in the indicated CSI subframe set, and the result of the CSI measurement is reported to the radio node. One of the at least two alternative CSI subframe sets relates to the one or more static subframes, and another one of the at least two alternative CSI subframe sets relates to the one or more flexible subframes.

  • Patent number: 9674034
    Abstract: A method of repairing communication disruption using a gateway, and an apparatus and a system therefor are disclosed. A method of repairing communication disruption in a gateway includes detecting whether failure in a communication line occurs by monitoring a change in voltage of the communication line, successively transmitting communication line disconnection request signals to first to Nth smart joint blocks when the occurrence of the communication line failure is detected, and determining whether the communication line failure is repaired after transmitting the communication line disconnection request signals. The communication line failure may be repaired by identifying a smart joint block causing the failure according to a result of the determination. Accordingly, the present invention has an advantage of providing more stable in-vehicle communication by automatically repairing communication line failure.

  • Patent number: 9674139
    Abstract: Presented herein are techniques to detect a misconfigured duplicate Internet Protocol (IP) address in a distributed data center network fabric. A network topology is provided that includes a plurality of network elements. A network element receives a configuration message comprising an IP address from a first host associated with the first network element. The IP address is detected to already be in use by a second host associated with a second network element. A request message is provided to the second network element, the request message configured to cause the second network element to attempt to contact the second host. A reply message is received from the second network element. If the reply message indicates that the second host exists at the second network element, an indication of a misconfiguration event is generated. Otherwise, the IP address is associated with the first host.

  • Patent number: 9635644
    Abstract: Aspects of the present disclosure provide techniques and apparatus for enhancing downlink coverage for certain user equipments (UEs) (e.g., low cost, low data rate UEs). Certain types of UEs may have limited coverage or should receive enhanced coverage relative to other types of UEs. For example, some types of low cost UEs may have only a single receive chain, thereby limiting DL coverage, while other types of UEs benefit from multiple receive chains. One example method generally includes identifying a first type of one or more UEs that is to receive enhanced downlink (DL) coverage relative to a second type of UEs and utilizing one or more DL coverage enhancement techniques when communicating with the first type of UEs, the one or more DL coverage enhancement techniques designed to adjust at least for reduced DL processing gain of the first type of UEs relative to the second type of UEs.

  • Patent number: 9628409
    Abstract: Techniques are described for supporting designated forwarder election for a multi-homed Ethernet virtual private network (EVPN) data center interconnect (DCI) between multiple data centers by leveraging and utilizing adjacency state information learned from a multicast routing protocol that controls multicast distribution within an underlying transport network of a local data center. For example, a set or routers operating to provide a multi-homed EVPN DCI may utilize adjacency state information learned from a Protocol Independent Multicast (PIM) executing within the underlying transport network of a multi-homed data center to facilitate selection of a designated forwarder for the EVPN between the data centers. By leveraging adjacency state information, an enhanced DF election may be automatically performed for the EVPN to facilitate selection of a designated forwarder in a manner that may avoid loss of traffic in situations where a topology event in the underlying transport network of the data center.
