  • Patent number: 12349074
    Abstract: According to some embodiments, a method is performed by a wireless device. The method comprises obtaining a data channel transmit power for transmitting on a sidelink data channel to a receiving wireless device, obtaining a control channel transmit power for transmitting on a sidelink control channel, and transmitting on the sidelink data channel at the data channel transmit power and on the sidelink control channel at the control channel transmit power. In certain embodiments, the control channel transmit power is based on the data channel transmit power. In other embodiments, the control channel transmit power is determined independently of the data channel transmit power.

  • 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.
