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.
