Abstract: An apparatus supporting multi-radio coexistence is provided. The apparatus is configured to support coexistence between multiple transceiver circuits configured to communicate radio frequency (RF) signals in a shared RF medium. In examples discussed herein, one transceiver circuit asserts a medium access request via a standard-defined coexistence interface for communicating an RF signal in the shared RF medium. The transceiver circuit may be configured to assert or de-assert the medium access request in response to a variety of trigger events. Depending on whether the medium access request is granted, the transceiver circuit may start communicating the RF signal in the shared RF medium in different modes. As such, it may be possible to reduce medium access delay for the transceiver circuit requesting to access the shared RF medium, while protecting the transceiver circuit currently occupying the shared RF medium from undue interruption and interference.
