  • Patent number: 9379842
    Abstract: A method and base station for adjusting outer-loop adjustment values used for link adaptation in a wireless communication network is provided. A modulation of a user equipment is determined and a success or failure of a Transport Block (TB) based on a TB feedback message is determined. Based on the TB feedback, one of an acknowledgement counter and a non-acknowledgement counter is incremented corresponding to the determined modulation. An upward step size for the determined modulation is updated based on the respective acknowledgement counter and the non-acknowledgement counter to affect link adaption.

  • Patent number: 9369188
    Abstract: A system and method are provided to trigger re-beamforming based on an algorithm that assesses various link characteristics. The algorithm is based on the ability of a 60 GHz receiving device to track and feedback a Received Signal Strength Indication (RSSI) to a 60 GHz data packet transmitter. By automatically analyzing RSSI values across a range of data packets, including consecutive data packets, a link degradation trend is predicted. When link degradation crosses, or is predicted to cross, a predetermined threshold, re-beamforming is triggered by the algorithm. Variables in the algorithm and the predetermined thresholds used by the algorithm can be automatically or manually modified to maintain a balance between appropriately triggering the re-beamforming when the conditions arise without unnecessarily triggering the re-beamforming thereby causing unneeded interruptions in regular data flow.

  • Patent number: 9331861
    Abstract: The invention relates to an Ethernet ring node (100) comprising a plurality of ports including at least two ring ports and at least one non-ring port. The Ethernet ring node comprises a multicast list including information on which port multicast traffic belonging to a multicast group should be sent. A control unit is provided configured to control a traffic distribution of multicast traffic to the different ports of the Ethernet ring node based on the information provided in the multicast list. Furthermore, a detector is provided detecting a topology change of the Ethernet ring in which the Ethernet ring node is provided. When such a topology change is detected, all multicast traffic is transmitted to the at least two ring ports for a predefined period of time, and multicast traffic transmitted to the non-ring ports is transmitted in accordance with the information provided in the multicast list.

  • Patent number: 9276699
    Abstract: A method and apparatus for controlling wireless communications by a multi-radio communication device is disclosed. An error control mechanism can be operated in accordance with a first mode of operation. Switching to a second mode of operation is provided in response to determining occurrence of a period of communication restrictions that is longer than a threshold. The error control mechanism is then operated in accordance with the second mode of operation during the period.

  • Patent number: 9258073
    Abstract: A network element for a packet-switched network has a plurality of network ports for exchanging synchronization messages with further network elements, a local clock, a timestamp generation module associated to each network port for triggering generation of a timestamp, and a synchronization control module selectively configurable in a first operating mode and a second operating mode as a function of a configuration signal. When the synchronization control module is configured in the first operating mode, it is adapted to adjust an offset of the local clock as a function of the timestamps of the synchronization messages received through the slave port. When the synchronization control module is configured in the second operating mode, it is adapted to compute a residence time of a synchronization message in the network element as a function of the timestamps obtained at the time of receiving and sending the synchronization message.
