  • Patent number: 10716022
    Abstract: Systems and methods for calculating uplink pathloss in a wireless local area network are provided. Uplink pathloss between an access point and client device operating in the wireless local area network can be calculated based on determining an effective maximum transmit power. Based on the effective maximum transmit power, and known uplink power headroom, a current transmit power of the client device can be determined. Based on the current transmit power of the client device, uplink pathloss can be determined. If the operating conditions and/or characteristics of the client device and/or wireless local area network change, the uplink pathloss may be re-evaluated.

  • Patent number: 10715287
    Abstract: In a base station, a control unit and a data size regulation unit control the data size of downstream assignment control data and upstream assignment control data in the PDCCH signal based on the communication format used between the base station and a terminal, the number of base station antennas (M) (nonnegative number), the number of terminal antennas (N) (nonnegative number), the bandwidth of the downstream band, and the bandwidth of the upstream band. Specifically, the control unit determines it is unnecessary to adjust the aforementioned data size when the selected communication format is first established between multiple antennas and when where there are multiple for one of M and N and only one for the other. The quality of downstream assignment control data is prevented from degrading, while preventing the number of blind determinations from increasing on the receiving side of the downstream control channel signal.

  • Patent number: 10708148
    Abstract: Many services measure quality of service (QoS) according to abstract metrics based on general heuristics of QoS determinants (e.g., VoIP service providers may presume that QoS is predominantly determined by network performance). However, users' QoS perceptions are often based on their experiences with particular activities of the service, which may utilize different service paths having different QoS determinants. Therefore, QoS may be measured by identifying the activities of the service, and the dependencies among the components of such services; for respective activities and dependencies, identifying a service path from the source to the user, and the segments comprising the service path; measuring the quality of the segments of the service path; and calculating the QoS of the activity according to the QoS of the segments of the service path providing the activity. This approach may yield QoS information of greater relevance to the users' experience and with greater analytic value.

  • Patent number: 10708170
    Abstract: A request for a chunk of data is received from an application executing on a remote device. The chunk of data is split into a plurality of packets including a first packet and a second packet. A first sub-flow is selected to transport the first packet to the remote device and a second sub-flow is selected to transport the second packet. The first sub-flow is decoupled from the second sub-flow. A first stop time is selected for the first sub-flow and a second stop time is selected for the second sub-flow. The first stop time determines when the first sub-flow will complete at the remote device and the second stop time determines when the second sub-flow will complete at the remote device. The first stop time and the second stop time are selected so that the first sub-flow and the second sub-flow will complete simultaneously at the remote device.

  • Patent number: 10700763
    Abstract: A reception unit receives from a wireless relay device, a handover response indicating possibility of degradation in communication quality during wireless communication with the wireless relay device. A search unit searches whether or not a wireless relay device to which handover can be performed is present other than the wireless relay device. When the wireless relay device to which handover can be performed other than the wireless relay device is present as a result of search by the search unit, a transmission unit transmits a handover request to the wireless relay device found by the search unit.

  • Patent number: 10693801
    Abstract: Implementations of the disclosure provide for queuing portions of the network traffic directed to a migrated guest for both receiving and transmitting at a source of the migration. In one implementation, a method is provided. The method comprises receiving, by a processing device via a network interface card (NIC), a first data packet. The first data packet includes a network address associated with a virtual machine (VM) that migrates from a first host to a second host. The first data packet is queued in a memory buffer at the first host in view of the network address. An indication that the network address of the VM is associated with the second host is received. Thereupon, the method causes the NIC to transmit the first data packet from the memory buffer over a network associated with the VM at the second host.

  • Patent number: 10686581
    Abstract: A method for transmit timestamp autocalibration includes generating a calibration pulse for calibrating a transmit timestamp in a transmitting device. The method further includes applying the calibration pulse to a transmit data pipeline in the transmitting device. The method further includes sampling a transmit timestamp when the calibration pulse reaches a timestamp sample triggering location in the transmit data pipeline upstream from an egress point of the transmitting device. The method further includes measuring a latency between a time that the calibration pulse reaches the timestamp sample triggering location and a time that the calibration pulse reaches a location downstream from the timestamp sample triggering location. The method further includes generating an adjusted timestamp based on the measured latency and inserting the adjusted timestamp into a data packet to be transmitted from the transmitting device.

  • Patent number: 10680939
    Abstract: Systems and methods of mesh network communication enabling a relay node to autonomously select a packet propagation mechanism. Upon receiving a packet, which may carry an indication for flooding propagation as set by the edge node originating the packet, or carry no specification for any propagation mode, the relay node determines whether the packet is eligible for routing-propagation based on a number of factors, such as whether there is an existent valid route from the source node to the destination node, whether the packet is originated from a friend edge node, and whether a route discovery process has been initiated. Accordingly, the relay node may change the indication to routing propagation and forward it by routing-relaying. Thus, the packet can be propagated over the mesh network by routing propagation, despite the initial setting for flooding propagation as specified by the edge node or no setting by the edge node.

  • Patent number: 10681397
    Abstract: A method of preparing data streams to facilitate seamless switching between such streams by a switching device to produce an output data stream without any switching artifacts. Bi-directional switching between any plurality of data streams is supported. The data streams are divided into segments, wherein the segments include synchronized starting points and end points. The data rate is increased before an end point of a segment, to create switch gaps between the segments. Increasing the data rate can include increasing a bandwidth of the plurality of data streams, for example by multiplexing, or compressing the data. The present invention can be used, for example, with MPEG or AC-3 encoded audio and MPEG encoded video segments that are multiplexed into MPEG-2 transport streams. Also included are specific methods for preparing MPEG video streams and multiplexing MPEG video with MPEG or AC-3 audio streams to allow a receiver to create seamless transitions between individually encoded segments.

  • Patent number: 10681592
    Abstract: When a UE is served by a first radio access network (RAN) and is engaged in a voice call such as a VoIP call, a determination will be made that the UE is at an edge of coverage (e.g., threshold poor coverage) of the first RAN and that there is no other adjacent coverage of the first RAN that could support the voice call. In response, signaling will cause a second RAN to page the UE via the first RAN so as to cause the UE to transition from being served by the first RAN to being served by the second RAN. More generally, when a UE has poor coverage of its serving RAN, another RAN will pull the UE to the second RAN by paging the UE to trigger transition of the UE from to the second RAN.
