Abstract: In certain embodiments, higher-level octree telepresence data for a point cloud of a 3D object is transmitted using a reliable transport mechanism that ensures successful transmission, e.g., via re-transmission of dropped packets, and lower-level octree data for the point cloud is transmitted using a non-reliable transport mechanism that does not guarantee successful transmission. When the lower-level data is contained in one or more of the bottom-most layers in the octree representation, at least some of the point cloud might be able to be reconstructed using successfully received data even when some lower-level data is lost and not re-transmitted. Using non-reliable transmission can reduce latency by avoiding time-consuming re-transmissions. The resulting reconstructed point cloud will be incomplete, but it might be sufficiently complete to provide satisfactory user experience with lower latency that using reliable transport for the entire octree.

Abstract: A basic (single-ended or differential) switchable transconductance amplifier has voltage-input circuitry and selector circuitry connected between capacitor circuitry and current-sink circuitry, where the capacitor circuitry and the selector circuitry are controlled to selectively convert an input voltage signal applied to the voltage-input circuitry into an output current signal, where the voltage-input circuitry and the selector circuitry are implemented at the same circuit level. More-complex circuits, such as multiplexers and de-multiplexers, can be based on the basic amplifier circuitry. By implementing the voltage-input circuitry and the selector circuitry at the same circuit level, the resulting circuit can have lower voltage overhead than equivalent prior-art circuitry, resulting in shorter switching time, higher operational bandwidth, and lower power consumption.

Abstract: A spectrum access system (SAS) includes a transceiver that receives information indicating a path loss from an interior location to an exterior location in response to a base station being installed at the interior location. The SAS also includes a processor to determine an aggregate interference level for an incumbent proximate the exterior location based on the path loss. An edge router executes instances of a packet core network. The edge router instantiates containers for a connectivity or digital automation enabler and routes customer network traffic without leaving the customer network. A domain proxy receives a request to allocate carriers to a base station and determines whether a frequency separation between the carriers is larger than a bandwidth allocated to an incumbent. The request is rejected if the frequency separation is less than the bandwidth and granted if the frequency separation is greater than or equal to the bandwidth.

Abstract: An apparatus, method and computer program is described above: determining a coupling gain for a user device within a cell of a mobile communication system; comparing the determined coupling gain with a coupling gain threshold; setting the user device to operate in a device-specific CSI-RS mode of operation in the event that the determined coupling gain is less than the coupling gain threshold, wherein, in the device-specific CSI-RS mode of operation, the user device is configured to use device-specific reference signal transmissions for the determination of channel state information; and setting the user device to operate in a cell-specific CSI-RS mode of operation in the event that the determined coupling gain is not less than the coupling gain threshold, wherein, in the cell-specific CSI-RS mode of operation, the user device is configured to use cell-specific reference signal transmissions for the determination of channel state information.

Abstract: Various example embodiments for supporting multicast are presented herein. Various example embodiments for supporting stateless multicast may be configured to support stateless multicasting of packets based on encoding of multicast path information within the packets. Various example embodiments for supporting stateless multicasting of packets based on encoding of multicast path information within the packets may be configured to use a recursive scheme of encoding the multicast path information within the packets such that the header that arrives at each node of the multicast path informs the node of the outgoing links over which the packet is to be sent and the headers to be sent on the outgoing links (e.g., each node of the multicast tree is able to recognize each of its outgoing links from the received header and send the appropriate subtree encoding down each of its outgoing links).

Abstract: Various example embodiments relate to expansion or compression of data of a transport block. A transmitter may comprise: means for receiving data for transmission in a transport block; means for determining, by an expander neural network, an expanded representation for the data of the transport block to cause the data of the transport block to have a designated size, wherein the expander neural network is an encoder of a reverse autoencoder neural network; and means for transmitting the expanded representation of the data in the transport block.

Abstract: To enable end-to-end performance monitoring, different solutions to obtain end-to-end values for different key performance indicators are disclosed. For example, when key performance indicator data from a plurality of different domains is received, the key performance indicator data received may be adapted to be a time-series data stream. Then, values of key performance indicators may be extracted, per a domain, from the time-series data stream. An end-to-end value for a key performance indicator may be determined, based on the extracted values of the key performance indicator in the different domains. The end-to-end value may be used for end-to-end performance monitoring of a network.
