  • Patent number: 10397899
    Abstract: A wireless communication device in a wireless network sets management information notification cycles at specified time intervals and transmits management information containing receive timing information showing its own position to start receiving information, receive window information, and receive cycle information. Another wireless communication device receiving that management information links it to a communication device number for the corresponding wireless communication device and stores the receive timing, the receive window information, and the receive cycle information. When sending information, the receive start position of the corresponding communication device is found from the receive timing information, the receive window information, and the receive cycle information of the other communication and information is then transmitted at that timing. An asynchronous ad-hoc communication wireless network can therefore be configured without a particular control station.

  • Patent number: 10397124
    Abstract: An adaptive network-based approach for reducing congestion on certain select-group of flows within a programmable network wherein switches dynamically adjust the receive window size (rwnd) and/or the ACK pace of other TCP flows by interfering their ACK packets, those flows sharing network resources causing congestion on the select-group of flows. The TCP flow rate is reduced to make more network resources available to the group of select-flows. The system of invention further comprises a centralized controller detecting so called a ‘bad queue’ causing persistent traffic slow-down due to TCP behavior. The bad queue detection is performed by (i) monitoring switch ports' transmit and receive queues, (ii) calculating minimum packet sojourn times on queues, (iii) determining which flows to slow down to clear detected bad queues, and (iv) sending messages to certain switches to execute changes to a group of ACK packets.

    Abstract: Pilots suitable for use in MIMO systems and capable of supporting various functions are described. The various types of pilot include—a beacon pilot, a MIMO pilot, a steered reference or steered pilot, and a carrier pilot. The beacon pilot is transmitted from all transmit antennas and may be used for timing and frequency acquisition. The MIMO pilot is transmitted from all transmit antennas but is covered with different orthogonal codes assigned to the transmit antennas. The MIMO pilot may be used for channel estimation. The steered reference is transmitted on specific eigenmodes of a MIMO channel and is user terminal specific. The steered reference may be used for channel estimation. The carrier pilot may be transmitted on designated subbands/antennas and may be used for phase tracking of a carrier signal. Various pilot transmission schemes may be devised based on different combinations of these various types of pilot.

  • Patent number: 10374913
    Abstract: A data retention probe for a packet-switched, mobile telecommunications network employs interfaces to connect to interfaces carrying traffic on a mobile network side of a gateway node and on a global internet side of the gateway node. A FPGA creates for each packet at least one fingerprint of one or more fields that are unchanged as part of the address translation performed by the gateway node and to create informative metadata for those packets. A processing unit: (1) receives from the FPGA the fingerprints and metadata and maintains flow records for each flow of packets seen on each side of the gateway node; and (2) compares the fingerprints and, where a match is found, determines those packets to be part of the same communication session and creates a record correlating internal IP address or a subscriber identifier to external IP address and port number.

  • Patent number: 10367751
    Abstract: One embodiment includes multiple distribution nodes sending packets of different ordered sets of packets among multiple packet switching devices arranged in a single stage topology to reach a reordering node. The reordering node receives these packets sent over the different paths and stores them in reordering storage, such as, but not limited to, in queues for each distribution node and packet switching device combination. The reordering node sends packets stored in the reordering storage from the reordering node in original orderings. In response to determining that an aggregation quantum of packets received from the multiple distribution nodes via a particular packet switching device and stored in the reordering storage is outside a range or value, packets being communicated via the particular packet switching device to the reordering node are rate limited.

  • Patent number: 10355825
    Abstract: A shared signaling channel has multiple segments, and parameters for this channel may or may not be sent to users in advance. For example, the number of segments, the size and rate of each segment, and so on may be broadcast to the users via an overhead channel. The transmit power for each segment is not broadcast to the users and can range from zero to the total transmit power. A base station obtains signaling for all terminals within its coverage and maps the signaling for each terminal to at least one segment used for the terminal, which may be dynamically selected. The base station processes (e.g., jointly or individually encodes) the signaling mapped to each segment and generates output data for the segment. The output data for each segment is multiplexed onto the system resources allocated for the segment and transmitted at the selected power level.

  • Patent number: 10356631
    Abstract: Disclosed herein is a method and corresponding apparatus to help manage wireless communication between a base station and a device served by the base. In accordance with the disclosure, when a base station transitions from serving the device on just a first carrier to serving the device on a combination of the first carrier and a second carrier, the base station will responsively take action to improve downlink communication to the device on the first carrier. In particular, the base station will respond to the occurrence of that transition by starting to beamform downlink transmission to the device on the first carrier.
