  • Patent number: 10382181
    Abstract: A method and apparatus for acknowledge mode data (AMD) re-segmentation are disclosed. An AMD protocol data unit (PDU) is generated from at least one RLC SDU. The AMD PDU size is within a flexible maximum AMD PDU size. The original AMD PDU is stored in a retransmission buffer, and transmitted. If transmission of the original AMD PDU fails and the original AMD PDU size is larger than an updated maximum AMD PDU size, the original AMD PDU is segmented to segmented AMD PDUs. If transmission of one of the segmented AMD PDUs fails, the original AMD PDU may be re-segmented to smaller size AMD PDUs.

  • Patent number: 10257013
    Abstract: A method of modulating and demodulating superposed signals for MUST scheme is proposed. A transmitter takes bit sequences intended for multiple receivers under MUST scheme to go through a “bit sequence to constellation points” mapper before entering the modulators to satisfy the Gray coding rule and to achieve high demodulation performance for the receivers. In a first method, each bit sequence is assigned for each constellation point on the constellation map to satisfy one or more conditions under different power split factors. In a second method, the constellation map is divided into sub-regions according to the clustering of the constellation points for bit sequence assignment. A near-UE may use an ML receiver for demodulation and decoding the superposed signal. A far-UE may use an ML receiver or an MMSE receiver for demodulation and decoding the superposed signal.

  • Patent number: 9998995
    Abstract: A method for reducing self-interference in a wireless network, such as a Link 16 network, while maintaining simultaneous multiple access takes advantage of the physical proximity of nodes in a localized subnetwork, such as a fighter-to-fighter subnetwork in a flight wing, by actively reducing the transmit powers used for subnet messages between the nodes. Calibration messages such as Precise Participant Location and Identification (PPLI) messages are exchanged between all of the nodes of the localized subnetwork, from which each node determines the identities, transmit powers, noise levels, and SNRs of all of the other nodes. The node then determines a link margin for other nodes, and sets its transmit power to a “safe” level for the subnetwork according to the lowest link margin.

  • Patent number: 9654276
    Abstract: A wireless local area network (WLAN) communication method and apparatus are provided. The WLAN communication method includes allowing a receiving station to receive a multi input multi output (MIMO) frame, allowing the receiving station to determine whether the MIMO frame is erroneous and whether the MIMO frame is destined for the receiving station, allowing the receiving station to generate a single input single output (SISO) acknowledgement (ACK) frame if the MIMO frame is not erroneous and is destined for the receiving station, and allowing the receiving station to transmit the SISO ACK frame to a sending station that has transmitted the MIMO frame.

  • Patent number: 9646018
    Abstract: Segment sizes are controlled by setting the size of a segment boundary in a hash-based deduplication system. A subsequence of size K of a sequence of characters S is set. Segment boundaries are set by using the sequence of the decreasingly restrictive logical tests if one of the sequence of the decreasingly restrictive logical tests returns a true value when applied on the sequence of characters S.

  • Patent number: 9628209
    Abstract: The invention relates to time synchronization between network testing elements in distributed network monitoring and testing systems, and provides a method for synchronizing packet timestamps generated by a network probe with a free running clock to a master clock connected at a different location of the network. In one implementation, the probe eavesdrops on a PTP message exchange between the master and a remote slave device, recording message reception times according to it free running clock and transmitting relevant timing information to a rest server for determining the probe clock offset and updating the probe packet timestamps.

  • Patent number: 9588544
    Abstract: Normalizing time across machines in a distributed system. A method includes obtaining one or more points defining differences in time between machines in the distributed system. Using the points, a determination of one or more time measurement drifts between machines is made. The one or more time measurement drifts indicate changing differences in time over time. One or more traces are collected. Each trace includes one or more events. Each event is correlated to a time stamp from one of the machines in the distributed system. Using the one or more determined time measurement drifts, the time stamps are normalized.

  • Patent number: 9432269
    Abstract: The present disclosure is directed towards systems and methods for lightweight identification of flow information by application. A flow monitor executed by a processor of a device may maintain a counter. The flow monitor may associate an application with the value of the counter and transmit, to a data collector executed by a second device, the counter value and a name of the application. The flow monitor may monitor a data flow associated with the application to generate a data record. The flow monitor may transmit the data record to the data collector, the data record including an identification of the application consisting of the counter value and not including the name of the application. The data collector may then re-associate the data record with the application name based on the previously received counter value.

  • Patent number: 9425893
    Abstract: In some embodiments, an apparatus includes a switch device that can be operatively coupled to a network having a set of links. The switch device can receive at a first time, a message having a set of physical coding sublayer (PCS) lanes. The message can include an error notification within a first subset of PCS lanes from the set of PCS lanes and not within a second subset of PCS lanes from the set of PCS lanes. The error notification is associated with signal degradation of a link from the set of links, where the switch device can send a first signal in response to receiving the message at the first time. The switch device can also receive at a second time a message without the error notification, and the switch device can send a second signal in response to receiving the message at the second time.

  • Patent number: 9414193
    Abstract: Systems, apparatus and methods for communicating and using a geofence while maintaining privacy are presented. A geofence is based on at least one RF fingerprint. The RF fingerprints include absolute information that is transformed into a one-way matrix (A) by application of a one-way function. The absolute information may identify a transmitter (e.g., by location, address or the like). An equation 0=Ax (where 0 is a zero vector, A is the one-way matrix and x is a signature vector) is solved to reveal one possible solution for the signature vector (x). This signature vector (x) is communicated rather than the RF fingerprints themselves, thus obscuring the absolute information and maintaining privacy.
