  • Patent number: 10721628
    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter device may determine that a communication is to be transmitted on a shared spectrum during a channel access interval not reserved for the communication. The transmitter device may determine, based at least in part on determining that the communication is to be transmitted, that a detection power of a listen-before-talk (LBT) operation satisfies a threshold. The transmitter device may transmit, after a coordinated rate control region and based at least in part on the detection power of the LBT operation satisfying the threshold, a reservation request signal associated with the communication. The transmitter device may transmit the communication before an end of the channel access interval based at least in part on a response to the reservation request signal. Numerous other aspects are provided.

  • Patent number: 10218528
    Abstract: A node forms a network by scanning for an existing network. If an existing network is not found, the node operates as a network controller node of the first network and admits at least one client node to the first network. As a network controller node, the node designates one of the client nodes as a scout node. The scout node removes itself from the first network and scans for a second network. If the scout node does not return to the first network after a predetermined time, it is assumed that the scout node has found a second network. The network controller node of the first network then designates the remaining client nodes as scout nodes, and then joins the second network as a client node. Therefore, multiple networks are avoided.

  • Patent number: 9930549
    Abstract: A method for communication between a wireless device node in a wireless sensor network (WSN) and control apparatus or control processes of an industrial control system is used to determine a method of radio transmission which provides a greater or a lesser measure of transmission quality between nodes. Thus a transmitter node measures a transmission quality metric of at least one packet received from two or more different switching branches, identifies which of the two or more switching branches has the greater transmission quality metric, distributes data packets with a first priority to the switching branch with the greater transmission quality metric, and transmits data packets with the first priority such as real-time data on the switching branch with the greater transmission quality metric. A wireless node, a sensor network system and a computer program for carrying out the method are described.

  • Patent number: 9917730
    Abstract: A peer-to-peer wireless controller topology provisioning system includes plurality of networking devices. A plurality of peer-to-peer wireless controllers are included in each networking device and are each configured to control a portion of a single wireless link with another peer-to-peer wireless controller. A management subsystem determines relative locations for each of the networking devices, and a number of peer-to-peer wireless controllers available in each of the networking devices. The management subsystem then uses a maximum hop constraint and a minimum bandwidth constraint to generate a peer-to-peer wireless controller topology for at least some of the peer-to-peer wireless controllers that are available in the networking devices.

  • Patent number: 9859975
    Abstract: An apparatus and a method for detecting an uplink optical signal. The apparatus includes a memory and a processor, where the processor is configured to determine a remaining bandwidth in a target uplink frame as a test window, where the remaining bandwidth in the target uplink frame indicates an unallocated bandwidth in the target uplink frame, and detect an uplink optical signal in the determined test window. Therefore, a remaining bandwidth obtained after bandwidth allocation in a target uplink frame is used to detect an uplink optical signal, which can effectively use a resource without the need of independently opening a test window and using an extra resource to detect the uplink optical signal, thereby avoiding waste of a resource and improving test efficiency.
