  • Patent number: 9860182
    Abstract: A data transmission device, method, and program therefor that effectively increase throughput even when a delay increase occurs due to a cause other than congestion in the network. The data transmission device (11) is provided with a transmission unit (60) which transmits to a user terminal (30) data requested over a network (20). The data transmission device includes a transmission rate control element (51C) which controls the transmission rate on the basis of the degree of congestion detected by a congestion detection element (51B) during delay measurement by a delay measurement processing unit (40), and a reference value correction processing element (51D) which temporarily corrects the detection criteria used by the congestion detection element; when it has been determined that the delay has increased due to a cause other than congestion. This reference value correction element increases the accuracy of detection processing by the congestion detection element, thereby improving throughput.

  • Patent number: 9832686
    Abstract: Mobile devices, base stations, and/or relay stations may implement CSFB (circuit switched fallback) operations by using RRC (radio resource control) connection release and/or handover procedures. If the CSFB RAT (radio access technology) target is not well configured, the UE may be informed and provisioned by the NW during a CSFB procedure with the information to return to LTE. Having this information, the UE may perform an autonomous search of LTE cells after the CSFB call release, speeding up return to LTE. To minimize potential call failures during CSFB, the UE may autonomously perform an additional cell search, in particular a search for cells on a RAT different from the initial target RAT. This creates an opportunity to prevent call failure of CSFB calls that would otherwise fail. The UE may be provisioned during the CSFB procedure with information to perform the additional cell search, should such a search be necessary.

  • Patent number: 9832800
    Abstract: A first terminal receives a first Timing Advance (TA) value from a base station and includes a second TA value that is obtained based on the first TA value in a Scheduling Assignment (SA) signal. The first terminal transmits the SA signal to a second terminal at downlink (DL) timing for receiving a downlink signal of the base station in cellular communication. When a length of a Cyclic Prefix (CP) that is set for the D2D communication and a length of a CP that is set for the cellular communication are different, the first terminal transmits data of the D2D communication to the second terminal at first timing that is obtained by applying the second TA value to the DL timing.

  • Patent number: 9780943
    Abstract: A system includes a transmitter to drive a transmission signal via a first and second transmission line. One half of the transmission signal is applied to the first transmission line and the other half of the transmission signal is applied to the second transmission line. An antenna radiates the transmission signal from the transmitter and receives a reception signal. The reception signal is driven in the opposite direction of the transmission signal on the first and second transmission lines. A plurality of differential amplifiers receive the reception signal from different sections of the first and second transmission lines and generate amplified output signals to a receiver output path having a first and second receiver transmission line. The differential amplifiers reject the one half of the transmission signal applied to the first transmission line and the other half of the transmission signal applied to the second transmission line.

  • Patent number: 9769003
    Abstract: This application presents a direct data recovery from subspaces or parameters subranges of a received OFDM signal preidentified as corresponding to specific data symbols, by applying adaptive inverse signal transformation (AIST) method for reversing both original data coding and deterministic and random distortions introduced by a transmission channel, wherein both reversals are achieved by the same conversion of the subspaces or parameter subranges into data transmitted originally in order to eliminate an intermediate recovery of signals or parameters transmitted originally within the received OFDM signal. The AIST includes using both amplitudes and gradients of amplitudes of OFDM tone signals.
