Abstract: Apparatuses, systems, and methods for a wireless device and a cellular base station to support common analog beam steering for band groups. The wireless device may provide an indication of analog beam steering capability of the wireless device to the cellular base station. For example, the wireless device may support a limited number of analog beams for each of one or more band groups. The cellular base station may select beam configuration information for the wireless device based at least in part on the indication of analog beam steering capability of the wireless device. This may include selecting a common beam for multiple component carriers for the wireless device based on the wireless device's analog beam steering capability. The cellular base station may provide the beam configuration information to the wireless device.

Abstract: An electronic device may include a set of antenna panels (APs) that transmit and receive signals within a set of signal beams. A proximity sensor such as a radar sensor may gather sensor data indicative of the position an external object. The device may select an AP and a beam that maximize wireless performance in communicating with a base station while also complying with the radio-frequency exposure (RFE). The device may select the AP and the beam based on the sensor data, per-panel and per-beam projected RFE values, antenna port RFE characteristics, per-panel and per-beam transmit power limits, per-beam transmit power backoffs, an RFE lookup table, regulatory RFE limits, and antenna performance metrics. The device may transmit an RFE report to the base station that identifies some or all of this information for use in updating scheduling for the device.

Abstract: A radio-frequency amplifier (51) may include input transistors (M1, M2) cross-coupled with capacitance neutralization transistors (M4, M4) and/or coupled to cascode transistors (Mcas1, Mcas2). One or more n-type gain adjustment transistors (Madj1, Madj2) may be coupled to source terminals of the capacitance neutralization transistors (M4, M4). One or more p-type gain adjustment transistors (Madj') may be coupled to source terminals of the cascode transistors (Mcas1, Mcas2). One or more processors (88) can selectively activate one or more of the gain adjustment transistors (Madj1, Madj2) to reduce the gain of the radio-frequency amplifier (51) without degrading noise performance and without altering the in-band frequency response of the radio-frequency amplifier (51).
