Abstract: Systems and methods described herein may enable user equipment to confirm and/or change a multiple input, multiple output (MIMO) communication configuration selected by a network, such as to change a number of data layers used in the MIMO communication and/or to change one or more antennas used in the MIMO communication. The user equipment may confirm and/or change the MIMO communication configuration based on transmit power levels associated with the one or more antennas, a distance between power amplifiers and respective antennas, or the like, as described herein.

Abstract: Embodiments described herein include methods and apparatus for dynamically selecting antenna settings for reception of wireless signals in multiple radio frequency band by wireless devices. A wireless device includes at least two SIM/eSIM profiles that each use different radio frequency bands and dynamically selects an antenna tuner setting based on requirements of one or more applications in use and key radio frequency performance indicators. In some embodiments, the antenna hardware tuner setting is selected to improve paging reception for a secondary SIM/eSIM from a second cellular wireless network when applications communicating using a first SIM/eSIM via a first cellular wireless network can accommodate performance degradation for a period of time.
