Abstract: Systems and methods described herein may introduce an intermediary device between radio access networks using a first spectrum and user equipment using a second spectrum. The intermediary device may process communication signals from either the first spectrum or the second spectrum into a format usable by the other of the first spectrum or the second spectrum. The intermediary device may be referred to as a multi-radio access technology (multi-RAT) translator.

Abstract: A distributed multi-antenna system includes a first access point configured to emit first beams to a user equipment device. The first access point is also configured to receive, from the user equipment device, an indication of a first beam selected from the first beams via a beam sweeping procedure. The distributed multi-antenna system also includes a second access point configured to receive, from the user equipment device or the first access point, the indication. The second access point is also configured to emit a second beam of second beams corresponding to the second access point to transmit data to the user equipment device based on the indication and a location of the second access point.

Abstract: A communication system may include a wireless base station (BS), one or more user equipment (UE) devices, and optionally one or more reconfigurable intelligent surfaces (RIS's). Phased antenna arrays may be implemented on one or more of these devices. The phased antenna arrays may exhibit beam squint. The beam squint may be leveraged to optimize communications efficiency in the system. For example, a transmit device may leverage beam squint to perform modulation coding scheme (MCS) adjustment, transmit power level adjustment, reference signal allocation, beam width adjustment, frequency domain resource allocation, carrier aggregation band selection, and/or beam management procedures. Beam squint may also be leveraged to ensure that satisfactory communications are maintained between the BS and the UE devices even as the UE devices move over time.
