Method of Establishing a Communication System and Communication System Therefor
A portable communication system for use in hostile and unknown environments. The system has a base station for control by an operator. The base station dispatches one or more unmanned drones into the hostile environment, where a forward agent, such a robot or investigative person can approach a suspected threat. Each drone has a payload of repeaters to be delivered as necessary to maintain line of sight communication from the forward agent back to the base station. Once delivered, the repeaters are mobile and can autonomously reposition to maintain or optimize line of sight communication. Communications from the forward agent back to the base station are then interpreted and analyzed for further action.
Repeater system and method for high-performance communication
A repeater system includes a first repeater device to receive a first beam of radio frequency (RF) signal from a first network node, and a second repeater device to receive a second beam of RF signal from the first network node. The first repeater device controls the second repeater device to provide the first beam and the second beam of RF signal to a second network node. A plurality of signal parameters is selected at the first and second repeater devices for a first beam and a second beam of RF signal, respectively. The first repeater device establishes an additional link with the second repeater device, where based on the additional link, a first data stream carried by the first beam of RF signal is provided to the second network node through the first repeater device as well as the second repeater device.
TECHNIQUE FOR RELAYING CONTROL MESSAGES BETWEEN A CORE NETWORK ENTITY AND RADIO DEVICES
A technique for relaying control messages between a core network entity of a communications network and radio devices served by the base station of the communications network is described. As to a method aspect of the technique, each of the control messages is relayed from one of the radio devices to the core network entity or from the core network entity to one of the radio devices. Each of the relayed control messages comprises an identifier that is indicative of at least one of the respective one of the radio devices and a user thereof. The control messages are stored at the base station, wherein the identifier is replaced in each of the stored control messages by a placeholder value that is independent of at least one of the respective one of the radio devices and the user thereof.

The telecom support unit may further include a microcontroller arranged to control operations of at least the streetlight.
Reconfigurable intelligent surface or repeater assisted synchronization signal block transmission and initial access
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a synchronization signal block (SSB) transmitted by a base station. The UE may receive system information that includes reconfigurable intelligent surface (RIS) or repeater assisted initial access information that identifies a set of SSBs that are associated with an RIS or a repeater and a modulation signature associated with the RIS or the repeater. The UE may selectively perform initial access using the SSB or search for another SSB based at least in part on the RIS or repeater assisted initial access information. Numerous other aspects are described.
MECHANISMS FOR REDUCTION OF OVERLAP DURING ZONE CASTING WITH ALTERNATIVE MAIN TRANSMITTERS AND TIME ALIGNMENT FOR OVERLAYED RADIO TRANSMISSIONS
Radio broadcasting equipment and functionality enable a radio broadcaster to reduce the size of an interference overlap resulting from main transmitter and booster signal transmitter overlap during zone casting by using an alternate main transmitter with an antenna pattern that differs from the main transmitter antenna pattern during zone casts. Radio broadcasting equipment is also provided that provides a mechanism to ensure that the handoffs occur in the gaps between songs, advertisements, or other content of both the main and the zone casting signals.
Smart directional repeaters with buffering capability
Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums to enhance the functionality of directional repeaters (wireless devices that relay directional wireless signals). For example, by adding even limited capability to buffer digital samples, repeater functionality may be enhanced to provide better coverage and make more efficient use of time, frequency, and spatial resources. An example method generally includes receiving, from a base station, a configuration indicating how the wireless device is to process stored digital samples of a first radio frequency (RF) signal, receiving the first RF signal, wherein the receiving comprises generating the digital samples of the first RF signal, storing the digital samples, and processing the stored digital samples according to the configuration.
Techniques for multiple transmission/reception point (multi-TRP) operation via repeaters
Methods, systems, and devices for wireless communications are described. In some examples, a base station may identify one or more communication paths to a user equipment (UE), and may determine an end-to-end signal quality for each communication path (e.g., a signal-to-noise ratio (SNR)), one or more hop SNR values for each hop of each communication path, a ratio of the hop SNR values and the end-to-end SNR of each communication path, or a combination thereof. Based on the determined SNR values, ratios, or both, the base station may select a first communication path for a first type of communications (e.g., uplink, downlink, signal type, or the like) and a second communication path for a second type of communications (e.g., uplink, downlink, signal type, or the like), and may communicate with the UE using the selected communication paths.
Coverage expansion and interference operating modes for a repeater
Methods, systems, and devices for wireless communications are described. In some systems, a repeater may receive a first signal from a transmitting device and determine an amplified version of the signal may not be successfully received by a receiving device. The repeater may transmit a mode switch message to the transmitting device to indicate a request for the transmitting device to switch to a transmission mode associated with one or more different transmission parameters based on detecting that the amplified version of the signal may not be received by the receiving device. The transmitting device may adjust one or more transmission parameters according to the mode switch message and may transmit a second signal to the repeater based on the adjusted transmission parameters. The repeater, operating according to the mode switch message, may receive the second signal and transmit an amplified version of the second signal to the receiving device.
