  • Patent number: 9667452
    Abstract: The present invention relates to a system and method for integrating useful data while measuring available bandwidth between a cloud computing client device and a server farm. More specifically the present invention relates to the method for integrating useful application data carried inside probe packets, by tools that estimate available bandwidth between two nodes connected through the internet (cloud). Importantly, the present invention relates to the method to overcome application data loss that typically happens during the available bandwidth estimation process. Advantageously, the Cloud Computing Environment (CCE) user's internet usage billing reduces significantly and also Available Bandwidth Measurement Tools (ABMT) could be run more frequently without significant increase in billing.

  • Patent number: 9094460
    Abstract: A fast send method may be selectively implemented for certain data packets received from an application for transmission through a network interface. When the fast send method is triggered for a data packet, the application requesting transmission of the data packet may be provided a completion notice nearly immediately after the data packet is received. The fast send method may be used for data packets similar to previously-transmitted data packets for which the information in the data packet is already vetted. For example, a data packet with a similar source address, destination address, source port, destination port, application identifier, and/or activity identifier may have already been vetted. A socket table may be maintained listing previously-transmitted data packets and an instruction for handling additional data packets similar to the data packet entered in the socket table.

  • Patent number: 9088314
    Abstract: A method is provided for reducing the peak power level in a combination of orthogonal frequency division multiplexed (OFDM) tones. The method is particularly effective when the information to be communicated is digital data consisting of long patterns of “1”s or “0”s. The digital data of the message is combined with a scrambling vector before the data is modulated. The randomization of data patterns, in turn, leads to a more random combination of OFDM tone amplitude being transmitted. The message is recovered at the receiver by removing the scrambling vector. An OFDM communication system using the above-described method is also provided.

  • Patent number: 9065650
    Abstract: In a communication system, activity of a transmitter (10), e.g., a UE, is controlled in response to a deactivation command (401). The transmitter (10) receives data on at least one transmission carrier and, if a received transmission of data is found to be defective, may send a repeat request to trigger a retransmission (404) of the data. In response to receiving the deactivation command (401), the transmitter (10) performs a check whether a retransmission (404) is expected on the at least one transmission carrier. If a retransmission (404) is expected, execution of the deactivation command (401) to deactivate the transmission carrier is delayed until the retransmission (404) is received or a timer has expired.

  • Patent number: 9031029
    Abstract: Provided are a radio communication terminal apparatus and a radio transmission method by which intersymbol interference of DM-RS of a CoMP terminal and a Non-CoMP terminal can be reduced. A CoMP set setting unit (102) sets the cell IDs of all cells in the CoMP set in a cell selection unit (104), and a serving cell setting unit (103) sets the cell ID of the serving cell in the cell selection unit (104). The cell selection unit (104) selects the cell ID having a number closest to the cell ID of the serving cell from the cells in the CoMP set. A sequence information calculation unit (106) derives a sequence group number from the selected cell ID, and the sequence information calculation unit (106) calculates a sequence number from the derived sequence group number and a transmission bandwidth of the DM-RS.

  • Patent number: 9001843
    Abstract: Automotive area networks (AAN) have a substantially fixed network topology, meaning that the physical media used for communications between devices included in the AAN is known. For example, the physical connections within an AAN, sometimes provided by wiring harnesses, can include fixed lengths of twisted pairs of wire (“twisted pairs”). Pre-compensation parameters related to characteristics of the twisted pairs can be determined at the factory, and loaded into the memory of devices connected to the AAN. These pre-compensation parameters are used to improve the fast wake up and link acquisition times of connected devices. Various characteristics of the physical communication channel are measured or estimated as a function of mechanical, ingress, climactic, and environmental variations (MICE), and used to update the pre-compensation parameters.
