  • Patent number: 11528684
    Abstract: A resource allocation method for coexistence of multiple line topological industrial wireless networks is provided. It pertains to the coexistence problem of multiple TDMA-based line topological industrial wireless networks, including three parts: lower bound analysis of scheduling delay, allocation algorithm of inter-network resources and allocation algorithm of intra-network resources. The method uses overall scheduling delay and resource utilization ratio as measurement indexes when analyzing the lower bound of delay and designing resource allocation algorithms, and selects a best node combination in each time slot to occupy as many channel resources as possible to improve the resource utilization ratio and reduce the overall scheduling delay.

  • Patent number: 11516850
    Abstract: In the embodiments of the present invention, UE can complete, by using only two interaction steps instead of six steps in the prior art, a process of sending a data packet to an eNodeB. Even a random access process in the six steps in the prior art includes four interaction steps, and by contrast, in the embodiments, signaling that needs to be consumed on an eNodeB when the UE sends data can be significantly reduced. This is relatively suitable for a scenario in which small data or occasional data is sent.

  • Patent number: 11425033
    Abstract: A network communication system may include intelligent electronic devices (IEDs) in a ring communication network. A software-defined networking device may be programmed by a removable or disconnectable software-defined network (SDN) controller to control the flow path of data packets to the IEDs in the ring network.

  • Patent number: 11398856
    Abstract: Systems, apparatuses, and methods for implementing beamforming techniques to choose transceivers in a wireless mesh network are disclosed. Multiple transceivers are deployed in a wireless virtual reality (VR) environment to provide a high quality path to send an encoded video stream from a graphics source to a head-mounted display (HMD) receiver. When a master transceiver connected to the graphics source does not have a line of sight connection to the HMD, the master transmitter sends the encoded video stream on a path though one or more passive transceivers that have good line of sight connections on the path to the HMD. To determine the quality of the wireless links between the various transceivers and the HMD, beamforming training procedures are performed. These beamforming training procedures are implemented to determine how to route the encoded video stream from the master transceiver to the HMD.
