  • Patent number: 10389644
    Abstract: A method and apparatus for controlling congestion of information packets in a computer network comprising at least a first node and a second node is provided. At each iteration of the method a transmission rate for information packets sent from the first node to the second node and a reception rate for responses received from the second node to the first node are determined. The rates may be determined from timestamps inserted into the information packets. The length of a congestion window is increased when a time average of the transmission rate is no greater than a time average of the reception rate and decreased when a time average of the transmission rate is greater than a time average of the reception rate by at least a threshold amount. Transmission of information packets is adjusted dependent upon the congestion window.

  • Patent number: 10341081
    Abstract: A user equipment (UE) comprises a radio having TX and RX paths that include a duplexer, thus facilitating a full-duplex mode. The radio may also have TX and RX paths that exclude the duplexer, and which thus facilitate a half-duplex mode. The UE may be configured to autonomously and opportunistically switch from the full-duplex mode (the paths that include the duplexer) to the half-duplex mode (the paths that exclude the duplexer) when the UE desires to avoid the path loss caused by the duplexer, e.g., to temporarily receive with greater sensitivity and/or transmit with more power, during poor channel conditions. At other times the UE may autonomously decide to remain in full-duplex mode to achieve reduced transmission time, e.g., during time-critical communications such as VoLTE. The UE may autonomously determine whether to use full or half-duplex mode, i.e., without requiring any coordination with network-side devices.

  • Patent number: 10334585
    Abstract: A method for coordinated multipoint transmission includes collecting, in a serving CoMP-MA, channel state information, CSIs, reported by terminals served by eNBs within a cooperating set. The serving CoMP-MA selects dominant interferers as candidate transmitting eNBs for a terminal. CoMP joint transmission is initiated by forwarding, to the candidate transmitting eNBs, PDCP PDUs received from SGW and targeted to the selected terminal, and by setting the status of the terminal to joint transmission. High and low thresholds of PDCP buffers of the serving CoMP-MA are adjusted. As information required for air interface scheduling becomes available, the method includes extracting, in the serving CoMP-MA, radio resource allocations, RLC and MAC headers, references to user plane data, and precoding matrices from protocol entities, and forwarding them to the transmitting eNBs that have acknowledged PDCP PDUs, in order the transmitting CoMP-MA to prepare air interface for the terminal.

  • Patent number: 10320508
    Abstract: A time synchronization system includes master nodes and slave nodes configured to correct a local slave clock by synchronizing time with time in a local master clock. A first master node corrects a first local master clock at predetermined periodic intervals by synchronizing with a timing synchronization signal from a source clock node having a source clock. If a second local master clock has a greater error from the source clock than the error in the first local master clock, the second master node performs first correction by synchronizing time with time in the first local master clock and performs second correction by synchronizing with the timing synchronization signal from the source clock node on condition that an error in the second local master clock is within a predetermined range after the first correction has been performed.
