  • Patent number: 11848898
    Abstract: Methods, systems, and devices for wireless communications are described. The described techniques leverage user equipment (UE) functionality to repeat wireless signals received from a base station to one or more other UEs and received from one or more other UEs to the base station. The repeating UE receives, during a transmission time interval reserved for one of uplink communication or downlink communication, a signal from a first device. The UE operates in a time division duplex network. The UE routes the signal, via a radio-frequency (RF) transmission path from an RF receive chain of the UE to an RF transmit chain of the UE. The UE retransmits the signal to a second device during the transmission time interval.

  • Patent number: 11736985
    Abstract: Integrated Access and Backhaul (IAB) nodes communicate with one another in half-duplex mode. Such a multiplexing of the communications of the IAB node requires simultaneous execution of a “mobile terminal” function and of a “base station” function by the IAB node. However, these two functions are not synchronised with one another, resulting in a lack of temporal alignment between the data communicated with the parent node and the data communicated with the child node, which causes interference that negatively impacts the quality of the communications between the different IAB nodes involved. Existing solutions suffer from long data processing times and are expensive. Accordingly, a time offset is introduced during the processing of the data by the child node, in order to take into account the lack of synchronisation between the “mobile terminal” function and the “base station” function of the current node.

  • Patent number: 11219076
    Abstract: One or more elements of a communication system receives a first indicator that a first wireless device is within a first coverage area of a first access node and is also within a second coverage area of a second access node. The first access node and the second access node are both configured to provide a multi-user multiple-input multiple-output (MU-MIMO) operating mode. The communication system determines a first number of wireless devices attached to the first access node that are utilizing the MU-MIMO operating mode. The communication system identifies the first wireless devices as being configured as a relay node. The communication system, based on the first number meeting a first threshold, instructs the first wireless device to attach to the second access node.

  • Patent number: 11212872
    Abstract: A method for a wireless network, including a node and a first device covered by the node, the node acting as serving node for the first device, and the first device transmitting first data to the node over a first link, includes determining presence of a second device covered by the node, the second device transmitting second data to a serving node over a second link, determining radio quality of the first link, determining radio quality of the second link, and determining radio quality of a third link between the second device and the first device. If the radio quality of the third link is higher than the radio quality of the second link, the second device transmits the second data to the first device over the third link and the first device retransmits, over the first link, the second data to the node.

    Abstract: A transport vehicle system includes transport vehicles each including a transport-vehicle-side communication unit, and a system controller including a controller-side communication unit to transmit a command in a predetermined order to any one of the transport vehicles as a destination and receiving a report from the transport vehicle being the destination. When receiving a command addressed to itself from the controller-side communication unit, the transport-vehicle-side communication unit transmits a report to the controller-side communication unit when a predetermined waiting time elapses after receiving the command. Meanwhile, the transport-vehicle-side communication unit transmits an interrupt request to the controller-side communication unit within a waiting time when intercepting a command addressed to another transport vehicle from the controller-side communication unit during a predetermined event in itself.
