Abstract: Apparatuses, systems, and methods for radio coexistence of a first radio with a first radio access technology (RAT) and a second radio with a second RAT, including systems, methods, and mechanisms for a wireless device to send a request message, from the first radio to the second radio to request a communication. The request message includes a request for the first radio to communicate in one or more frequency ranges that the second radio is configured to communicate on; a lead time for the first radio to start the communication in the one or more frequency ranges; a duration of time for the communication by the first radio; and one or more antennas of the UE for the first radio to use for the communication over the duration.

Abstract: Disclosed herein are system, method, and computer program product embodiments for synchronizing the switching of different wireless platforms to different portions of a frequency band. An embodiment, at a first wireless platform, operates by receiving a band switch request message from a second wireless platform, wherein the band switch request message comprises a band switch delay period for the second wireless platform. The embodiment calculates a band switch time based on a band switch delay period for the first wireless platform and the band switch delay period for the second wireless platform. The embodiment transmits a band switch accept message comprising the band switch time to the second wireless platform. The embodiment sets a first filter to operate on a second portion of the frequency band based on the band switch time. The embodiment then operates on the second portion of the frequency band.
