  • Publication number: 20250105986
    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.

  • Publication number: 20240250741
    Abstract: A communication system may include a base station (BS), user equipment (UE), and a set of reconfigurable intelligent surfaces (RIS's). The RIS's, the UE, and the BS may communicate using a control RAT and a data RAT. The BS may transmit downlink (DL) signals to the UE device via reflection off a DL RIS. The UE device may transmit uplink (UL) signals to the BS via reflection off a UL RIS. This may optimize wireless performance in situations where reflecting the UL and DL signals off the same RIS would limit performance under the current data RAT channel conditions. The BS and the UE device may use channel measurements of the control RAT at the RIS's to select the UL RIS and the DL RIS. This may significantly reduce overhead required to identify the UL and DL RIS's relative to scenarios where exhaustive beam training is used.

  • Patent number: 11867806
    Abstract: An acoustic imaging system includes a controller. The controller may be configured to receive a signal from a microphone and reverberation channel data, update latent variables, latent labels, a source amplitude, and a phase estimation based on an optimization of the signal and reverberation channel data to obtain updated latent variables, updated latent labels, an updated source amplitude, and an updated phase estimation, generate, via a conditional generative adversarial network (cGAN) of the updated latent variables and the updated latent labels, an acoustic source map tuned via the updated source amplitude and the updated phase estimation, optimize the acoustic source map, and output the optimized acoustic source map.
