  • Patent number: 10959268
    Abstract: Methods, systems, and devices for wireless communications for determining a minimum time gap between an received downlink message and transmission of an uplink message in response to the received downlink message. In some cases, a user equipment (UE) may receive a downlink message to perform a random access procedure. The UE may determine a minimum time gap based on an uplink transmission preparation time. The UE may transmit a random access preamble based on the minimum time gap. In some examples, the UE may receive a timing advance (TA) command and may determine a minimum time gap between receipt of the TA command and transmission of a time-adjusted uplink message.

  • Patent number: 10887131
    Abstract: Some embodiments described herein provide a combination of a layer 3 (L3) hop with layer 2 (L2) bypass/fail-to-wire in a network device. Specifically, some embodiments place the network device between two routers, thereby becoming a L3 hop between the two routers. The existing route between the two routers is preserved by using L2 bypass through the network device. If the network device fails, then the physical fail-to-wire will be engaged, removing its L3 hop, but preserving the L2 bypass.

  • Patent number: 10856154
    Abstract: Aspects of the disclosure provide a method for restoring connectivity among partitioned segments in a partitioned wireless sensor and actor network (WSAN). The method includes placing batches of mobile nodes at locations surrounding mobile nodes previously placed within a damaged area of the partitioned WSAN, spreading the batches of mobile nodes, determining whether connectivity among the partitioned segments has been restored, and repeating placing batches of mobile nodes, spreading the patches of mobile nodes, and determining whether connectivity among the partitioned segments has been restored when connectivity among the partitioned segments is not restored. The method is based on a distributed dropping approach which introduces minimal disruption to previously deployed mobile nodes, and decreases total traveled distance a mobile node might move compared with a traditional central dropping approach.
