[Object] To improve the reliability by using an acknowledgement response while using radio resources efficiently in multicast transmission over wireless transmission.

[Solution] A plurality of wireless communication devices included in a multicast group, when receiving a data frame, transmit simultaneously an acknowledgement response of multicast using spatial multiplexing in response to an acknowledgement request from a transmission source. On the other hand, a wireless communication device of the transmission source decomposes the acknowledgement responses simultaneously received into the original individual acknowledgement responses and restores them using signal processing based on information on a channel with each wireless communication device of a transmission destination.

A media flow transport security manager of a hybrid cloud-based media production system having a network orchestrator and an extensible resource manager (ERM) includes a firewall communicatively coupled to a computing platform having a hardware processor and a memory storing a security software code. The hardware processor executes the security software code to communicate with the network orchestrator to identify multicast production media flow(s) for processing in a cloud-based virtual production environment, and to communicate with the ERM to obtain an identifier of each cloud-based resource used for processing cloud production media flow(s) corresponding to the identified multicast production media flow(s). The hardware processor also executes the security software code to receive an alert that the cloud production media flow(s) have been processed to generate corresponding post-production cloud media flow(s), and to route, using the obtained identifier of the cloud-based resource(s), the post-production cloud media flow(s) through the firewall.

Methods, devices, and systems for operating a fire system network are described herein. One method includes receiving a plurality of time-slotted maintenance messages over a period of time from each of a plurality of fire system devices located in a facility via a first spreading factor, receiving an event message from a fire system device of the plurality of fire system devices responsive to the fire system device determining a fire event, the event message sent via a second spreading factor, and sending a block actuate message to the plurality of fire system devices responsive to receiving the event message, wherein the block actuate message is configured to activate a fire alarm.

A system and method for providing and managing a remote patient monitoring (RPM) system. The method is implemented by a central server, an RPM client, and a networked monitoring device. The RPM client is a software program that is executed by a computing device that is connected to the server via a network. The networked monitoring device is implemented as a locator or a smart mobile cart. More specifically, the RPM system can provide a tele-monitor with the ability to remotely monitor multiple patients, control remote cameras, and address abnormal patient situations. The RPM system can enhance tele-monitor effectiveness by detecting patient motion and tracking tele-monitor alertness.

When transmitting signals from a plurality of base stations (broadcasting stations), the base stations include at least a first base station having a first antenna with a first polarization and a second base station having a second antenna with a second polarization that is different from the first polarization. Then, when the first base station transmits a signal β rom the first antenna having the first polarization, the second base station transmits the same signal as the first antenna of the first base station from a second antenna having the second polarization, at the same time.

Full-duplex communications over a single-wire bus is described in the present disclosure. In embodiments disclosed herein, a master circuit and a slave circuit(s) are able to communicate forward (master to slave) bus telegrams and reverse (slave to master) bus telegrams concurrently over a single-wire bus consisting of one wire. Specifically, the master circuit is configured to modulate the forward bus telegrams based on voltage pulse-width modulation (PWM), while the slave circuit(s) is configured to modulate the reverse bus telegrams based on current variations. In addition, the slave circuit(s) is further configured to harvest power from the master circuit concurrent to receiving the forward bus telegrams and sending the reverse bus telegrams. By supporting full-duplex communications over the single-wire bus, it is possible to improve efficiency, cost, and power consumption in an electronic device wherein the single-wire bus is deployed.

Secure network segmentation using logical subnet segments is described. A single network segment or subnet provided by a third party is mapped into multiple layer-3 virtual or logical segments without requiring separate subnets. This mapping is accomplished by using virtual routing functions (VRFs) per logical subnet segment while retaining a single subnet across the segments. The logical subnet segments interact with the single network segment provided by the third party (ISP). The layer-3 VRF instances are created without the need for separate IP subnet pools per layer-3 segment. Each VRF instance for the various logical subnet segments is mapped to an identifier and tag.

Systems, methods, apparatuses, and computer program products for broadcast service restoration for multicast/broadcast service upon radio access node failure or restart are provided. For example, a method may include storing a last multicast/broadcast service session information received from a multicast/broadcast session management function corresponding to a multicast/broadcast service session. The method may also include detecting that a radio access node associated with the multicast/broadcast service session has restarted or is unreachable. The method may further include taking a further action to adjust the delivery of the multicast/broadcast service session based on the detection.

A setting change method that causes a computer to execute processing includes: receiving a setting change request packet for a kernel from software operating over a container executed in one of OSs; acquiring identification information of one of communication modules that has received the setting change request packet, from the received setting change request packet; and referring to a storage unit that stores information indicating correspondence relationships between identification information of the OSs and the identification information of the communication modules in the OSs and determining the OS in which the container is operating based on the acquired identification information of the communication module.

Embodiments of the disclosure provide a method performed by a broadcast/multicast server for a communication network. The method comprises: receiving, from an application server, a request to establish a broadcast/multicast bearer in the communication network; allocating resources associated with the broadcast/multicast bearer in the communication network; and sending, to the application server, a response message comprising an indication of whether the allocation of the resources associated with the broadcast/multicast bearer is ongoing or not. Corresponding apparatus, and methods and apparatus in the application server, are also provided.
