  • Patent number: 10031880
    Abstract: The application provides a network device, which includes: a main control board and a service board, where the main control board includes a processor and a switching chip, and the service board includes a physical layer component. The switching chip is connected to the physical layer component by using a system bus. The system bus consists of a SerDes link, and is configured to transmit service data and control information of a port of the physical layer component. The processor controls the port of the physical layer component by using the control information of the port of the physical layer component. The network device transmits the service data and the control information by using the system bus, so that the service board does not need to set a CPU processing the control information, thereby expanding an interface flexibly, and reducing device complexity and hardware costs.

  • Patent number: 10020952
    Abstract: Techniques are described for operating a network switch device associated with a virtual layer two (L2) network instance according to a protocol independent multicast (PIM) relay mode. The PIM relay mode enables the network switch device to receive a PIM control message, i.e., a PIM join and/or prune request, for a multicast group on a downstream port of the network switch device associated with a virtual L2 network instance, determine an upstream neighbor port of the network switch device associated with the instance, and relay the PIM control message on the upstream neighbor port of the network switch device without flooding the PIM control message on all ports of the switch device associated with the instance. In the PIM relay mode, the network switch device avoids triggering join suppression in downstream PIM neighbor devices with receivers, and avoids maintaining upstream states and setting a PIM periodic message timer.

  • Patent number: 10004076
    Abstract: In a general aspect, a wireless communication channel is selected based on signal quality metrics. In some aspects, a first wireless communication device receives a first set of signals based on wireless signals transmitted through a space on a first wireless communication channel from a second wireless communication device. A signal quality metric value is computed based on the first set of signals, and a second wireless communication channel is selected based on a determination that the value of the signal quality metric does not meet a quality criterion for a motion detection process. The first wireless communication device receives a second set of signals based on wireless signals transmitted through the space on the second wireless communication channel from the second wireless communication device, and the motion detection process is executed to detect motion of an object in the space based on the second set of signals.

  • Patent number: 9979516
    Abstract: It is intended to provide a transmission device, a reception device and a communication system capable of improving transmission characteristics by performing packet combining by HARQ in MU-MIMO transmission using non-linear precoding. In a case of receiving NAK from any of terminal devices (400), a base station device (100) retransmits a packet, in which an error occurs, addressed to this terminal device. The base station device (100) transmits the data to be retransmitted together with other transmission data addressed to a different terminal device or addressed to the own terminal device by spatial multiplexing transmission with MU-MIMO. At this time, for the retransmission data, precoding is performed such that a perturbation term same as a perturbation term which has been added to this data by non-linear precoding at the time of initial transmission is added.

  • Patent number: 9973315
    Abstract: Methods, systems, and devices for transmission and reception of SPS communications are disclosed herein. User equipment (UE) is configured to receive, in a first subframe, a physical downlink control channel or enhanced physical downlink control channel (PDCCH/EPDCCH) corresponding to semi-persistent scheduling (SPS) activation. The PDCCH/EPDCCH conveys a value of nSCID. The UE configures, based on the SPS activation, a downlink (DL) assignment in a second subframe for receiving an SPS physical downlink shared channel (PDSCH) without a corresponding PDCCH/EPDCCH. The UE determines a reference signal sequence corresponding to the SPS PDSCH using nSCID derived from the PDCCH/EPDCCH corresponding to the associated SPS activation. The UE receives the SPS PDSCH in a second subframe. The UE processes the SPS PDSCH based on the reference signal sequence for the SPS PDSCH in the second subframe using the nSCID derived from the PDCCH/EPDCCH corresponding to the associated SPS activation.
