Abstract: An electronic device may include wireless circuitry with a baseband processor, a transceiver, and an antenna. The antenna may be coupled to one or more antenna tuning elements for tuning the antenna over multiple communications (frequency) bands of interest. The baseband processor may be configured to simultaneously broadcast, over a digital interface, an aggregate message that includes control bits for adjusting multiple antenna tuning elements coupled to the digital interface. Adjusting multiple antenna tuning elements by issuing a single broadcast command can help optimize interface efficiency while maintaining compatibility with existing industry standards.

Abstract: This disclosure relates to techniques for coordinated channel state information reporting in a wireless communication system. A wireless device may establish a wireless link with a cellular base station. The wireless device may determine to coordinate channel state information reporting with another wireless device. Information may be exchanged with the other wireless device via a sidelink wireless link. The wireless device may provide channel state information to the cellular base station. The channel state information may be determined based at least in part on the information exchanged with the other wireless device via the sidelink wireless link.
