  • Patent number: 10142865
    Abstract: A network equipment test device includes per-UE uplink signal generation processing chains for generating per-UE time domain uplink signals. Per-UE signal faders simulate per-UE signal fading for the per-UE time domain uplink signals. Different phases and amplitudes are used over time to simulate different signal fading. Fourier transformation units perform Fourier transformation of each of the time domain uplink signals to produce per-UE frequency domain uplink signals with simulated per-UE signal fading. A subcarrier mapping unit performs subcarrier mapping of the per-UE frequency domain uplink signals to produce a frequency domain multi-UE uplink signal with simulated per-UE signal fading. An inverse Fourier transformation unit performs inverse Fourier transformation of the frequency domain multi-UE uplink signal to produce a multi-UE time domain uplink signal with simulated per-UE signal fading.

  • Patent number: 10116493
    Abstract: Systems, methods, and non-transitory computer-readable storage media for recovering from a partial failure of a virtual port chain (vPC) domain. The first and second vPC peers may be paired to create a vPC having a virtual address. An endpoint host may communicate with a network via the virtual port channel. The system may detect that the first virtual port channel peer is down. During or after the first vPC reboots, the reachability cost for the first vPC with regards to the virtual address can be set to an inflated value. The first vPC peer may also delay its bring up time while it synchronizes its vPC state information with the second vPC peer. The second vPC can continue to advertise the association between the endpoint host and the virtual address. Upon completion of the synchronization, the first vPC peer may bring up the link and restore the reachability cost.

  • Patent number: 10091817
    Abstract: A wireless first device may receive a packet from another device from an overlapping basic service set (OBSS). A received power of the packet may be greater than a threshold for transmitting during the time of the packet. If the first device reduces its transmit power, the first device may increase the threshold. If the received power is less than the increased threshold, the first device may count down a backoff count during a transmission time or transmission opportunity of the packet. In some cases, after the transmission time or transmission opportunity, the first device may increase its transmission power. In some cases, the condition for counting down a backoff count may also include initiating or finishing the transmission during the transmission time or the transmission opportunity of the packet, or transmitting at the reduced power.
