A device including a first transceiver and a second transceiver. The first transceiver is configured to selectively transmit and receive first signals in a first frequency band according to a schedule. The first signals include at least cellular signals. The second transceiver is configured to selectively transmit and receive second signals in a second frequency band different from the first frequency band. The second signals include at least WiFi signals. An arbiter is configured to generate status reports indicating statuses of channels in the first frequency band and/or the second frequency band, receive the schedule as generated based on the statuses, and selectively modify the status reports based on an expected transmission and/or reception of the first signals by the first transceiver, and/or an expected transmission and/or reception of the second signals by the second transceiver.
