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.
