Abstract: This disclosure relates to methods, devices, and systems for wireless communications, and more particularly uplink reference signal repetition for non-terrestrial networks. A user terminal in a non-terrestrial network may identify an uplink reference signal format that includes a comb-based pattern of subcarriers within a first orthogonal frequency-division multiplexing (OFDM) symbol and within a second OFDM symbol for transmission of an uplink reference signal. The user terminal may map the uplink reference signal to a first set of subcarriers within the first OFDM symbol and to a second set of subcarriers within the second OFDM symbol in accordance with the comb-based pattern. Thereby, the user terminal may transmit, to a base station in the non-terrestrial network, the uplink reference signal on the mapped subcarriers of the OFDM symbols, which may be transmitted coherently.

Abstract: A networking system may perform a border gateway protocol (BGP) switchover from an active BGP process to a standby BGP process. The standby BGP process may obtain transport layer protocol state information, for a given time, of a transport layer session for the active BGP process. The standby BGP process may update the transport layer protocol state information based on BGP messages conveyed, after the given time, over the transport layer session and forwarded to the standby BGP process. Based on a BGP switchover criterion being met, a replacement transport layer session may be set up using the updated transport layer protocol state information. The replacement transport layer session continues the transport layer session after the BGP switchover.

In this way, the recipient device is protected from stale packets.

The server determines whether the device corresponds to a preexisting device registration. When the remote third-party server is determined to correspond to the preexisting third-party server registration and the device is determined to correspond to the preexisting device registration, the server determines whether the condition detected by the device at the premises is an alarm condition. When the condition detected by the device at the premises is determined to be the alarm condition, the server transmits an alarm signal to a central monitoring station.

Abstract: A mechanism for error containment in a data processing system includes receiving a transaction request at a gateway between a host and a device, allocating an entry for the request in a local request tracker of the gateway and sending a link request, to a port of the gateway. In response to an isolation trigger, the port is moved into isolation by completing in-process requests with entries in the tracker and locking the entries. On receiving a response to an in-process request while the port is in isolation, the response is dropped, the associated entry is unlocked, and allocation of the entry is enabled. A completion response is sent to the requester without dispatching a new link request to the port. When requests are completed, the system is quiesced, locked entries are unlocked, and the port is moved out of isolation.
