  • Patent number: 11546775
    Abstract: In order to facilitate communication in a shared-license-access band of frequencies, an electronic device (such as an electronic device that implements a spectrum allocation service) allocates, to a radio node in a set of radio nodes, at least a first channel and a second channel in unallocated channels in the shared-license-access band of frequencies. Note that the first channel and the second channel are noncontiguous in the shared-license-access band of frequencies. Then, the electronic device monitors for transmissions by a higher-priority user than the set of radio nodes in the shared-license-access band of frequencies. When the transmissions are detected in the first channel, the electronic device instructs the radio node to discontinue use of the first channel, where allocation of at least the second channel allows uninterrupted communication by the radio node in the shared-license-access band of frequencies.

  • 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: 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.
