An electronic apparatus and control method thereof are provided. The electronic apparatus includes a sensor, a communicator, and a processor configured to, based on a wireless communication between a relay device and a terminal device being sensed by the sensor, identifies whether the relay device and the terminal device is an authorized device, and based on at least one of the relay device or the terminal device being identified as an unauthorized device, controls the communicator to transmit a beacon signal including communication channel transfer information to the terminal device.

An origination device transmits a “received data signal” to a signal forwarding device. The “received data signal” comprises a first set of data. The origination device also transmits at least one “received control signal” to the signal forwarding device and to a destination device. The at least one “received control signal” comprises a first set of control information and a second set of control information. The first and second sets of control information are both associated with the first set of data. The first set of control information contains instructions pertaining to the signal forwarding device processing the first set of data. The second set of control information contains instructions pertaining to the destination device processing the first set of data. The signal forwarding device transmits a “forwarded signal” to the destination device. The “forwarded signal” contains forwarded data, based on the first set of data.

Systems and methods may include one or more devices associated with a relay network. In some examples, a relay device may be configured to determine, based at least partly on a control signal received from a destination device on a first carrier frequency, channel estimates for a channel between the relay device and the destination device. The device may determine, based at least partly on the channel estimates, a weighting function for transmissions from the relay device to the destination device. The device may generate baseband samples based on a down-conversion, from a second carrier frequency to a baseband frequency, of one or more incoming RF signals and apply the weighting function to the baseband samples to generate weighted baseband samples. The device may generate an outgoing RF signal based on an up-conversion of the weighted baseband samples from the baseband frequency to the first carrier frequency.

The technology is generally directed towards configuring, coordinating, and operating across multiple frequency carriers or bands on one or more access and backhaul links. An integrated access and backhaul (e.g., child) node, for example, determines first multiplexing capability data representative of a first multiplexing capability for a first frequency resource, and determines second multiplexing capability data representative of a second multiplexing capability for a second frequency resource. The first and second multiplexing capability data for the first and second resources are communicated to a second (e.g., parent) integrated access and backhaul node. Quality of service can be applied across multiple frequency carriers utilized by the integrated access and backhaul node for access and backhaul links. Also described is supporting multifrequency operation outside of the radio access network for non-new radio-based traffic backhauling.

A network environment includes a repeater wireless station. The repeater wireless station receives a first wireless signal from a wireless base station. The repeater wireless station transmits a second wireless signal from the repeater wireless station. The second wireless signal is a reproduction of the first wireless signal. When transmitting the second wireless signal, the repeater wireless station controls a phase shift of the second wireless signal with respect to a timing of the received first wireless signal to reduce wireless interference in the network environment.

A method performed by a first RAN node of an integrated access and backhaul, IAB, wireless communication network. The first RAN node is connected to a core network and is arranged for wireless communication with a second RAN node and with a number of UEs. Wireless communication resources are allocated for communication between the first RAN node and the second RAN node. The method includes assigning a first part of the resources for transmission of first data and a second part for transmission of second data between the first RAN node and the second RAN node, obtaining information of a vacant part of the resources, and triggering transmission of the first data and the second data using at least a fraction of the vacant part of the wireless communication resources for at least one of the first data and the second data.

Methods, systems, and devices for wireless communications are described for relaying communications from a source device to a destination device via one or more relay devices. Scheduled resource grants may be used to provide resources for the relayed communications, and may provide one or more associated relaying parameters for relayed communications. A source device and relay device may use parameters to determine a relaying priority for multiple communications that are to be relayed. Additionally or alternatively, scheduled resource grants may include energy harvesting (EH) parameters for communications that use the scheduled resources. The EH parameters may include, for example, time-switching energy harvesting parameters that configure a first subset of symbols for data and a second subset of symbols for EH, or power-splitting EH where power of a received signal is split between EH components and decoding components.

An enhanced L-band Digital Aeronautical Communications System (LDACS) may include LDACS ground stations; and a LDACS airborne stations, each configured to communicate with the LDACS ground stations at a given class of service from among different classes of service. The enhanced LDACS may also include a network controller configured to operate the LDACS ground stations and LDACS airborne stations at the different user classes of service.

There is provided a method to operate a downstream IAB, Integrated Access and Backhaul, node of an IAB network, is provided, wherein the method comprises: receiving a first radio resource configuration that indicates a use of radio resources by the upstream IAB node and by at least one radio node served by the upstream IAB node; determining a second radio resource configuration or the downstream IAB node in dependence on the first radio resource configuration; and communication with at least one radio node, which is served by the downstream IAB node, via radio resources according to the second radio resource configuration.

Technology for a repeater is disclosed. The repeater can include a signal path that includes a digital filter. The repeater can include a controller. The controller can receive plurality of signals in a multi-channel downlink signal band. The controller can digitize one or more signals in the multi-channel downlink signal band to form a plurality of digitized downlink signals. The controller can use the digital filter to adjust a gain of one or more of the digitized downlink signals based on a channel-specific received signal strength indicator (RSSI) or a network protection requirement.
