Abstract: A communication system includes a core network and a radio access network including a central unit communicatively coupled to (i) the core network via a backhaul network, and (ii) a plurality of distributed units via a fronthaul network. Each of the distributed units is co-located with a radio unit and comprises a multi-access edge computing (MEC) module.

Abstract: A communication system includes multiple nodes of a time-sensitive network and a scheduler device. At least one of the nodes is configured to obtain a first signal that is represented in a frequency domain by multiple frequency components. The scheduler device generates a schedule for transmission of signals including the first signal within the time-sensitive network. The schedule defines multiple slots assigned to different discrete frequency sub-bands within a frequency band. The slots have designated transmission intervals. The nodes are configured to transmit the first signal through the time-sensitive network to a listening device such that the first signal is received at the listening device within a designated time window according to the schedule. At least some of the frequency components of the first signal are transmitted through the time-sensitive network within different slots of the schedule based on the frequency sub-bands assigned to the slots.

Abstract: A radio network (e.g., a multiple-input multiple-output (MIMO) radio network) includes a transmitter node and a receiver node. The transmitter node is configured to determine whether a radio link (e.g., a MIMO link) associated with a plurality of subchannels is carrying time sensitive networking (TSN) traffic. In accordance with a determination that the radio link is carrying TSN traffic, the transmitter node is configured to obtain configuration values (e.g., a plurality of channel path coefficients) based on estimated quality of each of the plurality of subchannels; adjust the configuration values such that variance in quality of the plurality of subchannels is minimized; and transmit data to the receiver node via the plurality of subchannels in accordance with the adjusted configuration values.

Abstract: Systems, methods, techniques, and other embodiments are disclosed with regard to a communication network, e.g., a wireless network, configured to support time-sensitive deterministic communication based on a time-sensitive network (TSN) mechanism. The network may include discrete communication network (CN) components, wherein each CN component is to provide a discrete functionality for data communication from a source device across the wireless network to a destination device. A processor may be arranged to configure at least one of the CN components with a set of TSN parameters of the TSN mechanism such that that CN component supports time-sensitive deterministic communication as a TSN block in a TSN network in accordance with the set of TSN parameters. The network may include a plurality of configuration modules interconnected in a certain arrangement and configured to provide a unique set of TSN parameters to each of the CN components, which thus supports time-sensitive deterministic communication.

Abstract: An IP multicast broadcast device, an IP multicast receiver device, and a method of congestion control in reliable IP multicast are described that mitigate the impact of signal blockage in radio-based IP multicast networks. In one example multicast network, the IP multicast broadcast device, and the IP multicast receiver devices may be configured to support an IGMP-based multicast protocol in which a NORM protocol, a congested packet marking protocol, e.g., such as the ECN protocol described above, and a router congestion prediction protocol, e.g., such as the RED protocol, have been implemented. In addition, the implemented NORM protocol may implement a TCP congestion control algorithm that generates adjusted transmission rates based, at least in part, on a count of ECN congestion marked packets and a count of dropped packets at a selected receiver. As a result, the generated transmission rates are not unduly affected blockage of the radio-based transmission signal.

Abstract: A method of producing a thickened organic polymeric composition useful for molding and capable of resisting post-molding shrinkage after being crosslinked comprising a cross-linkable base resin dissolved in an unsaturated monomer, and an additive resin selected from saturated polyesters and saturated amide waxes, the additive resin being crystalline at ambient temperatures and having a melting point (T.sub.m) below a temperature (T.sub.c) at which the base resin cross-linking reaction proceeds at a significant rate. The base resin and additive resin have only a partial degree of compatibility. When cooled from a temperature between T.sub.m and T.sub.c to temperature between T.sub.m and ambient the composition thickens, whereas, when it is heated to a temperature below T.sub.c, it reverts to a flowable composition.
