An example system and method, during operation of first communication circuitry in a first operating mode comprising first power consumption, uses the first communication circuitry to perform packet arbitration for wireless communications by the first communication circuitry, second communication circuitry, and third communication circuitry. During operation of the first communication circuitry in a second operating mode comprising second power consumption, the example system and method uses the second communication circuitry to perform packet arbitration for wireless communications by the second communication circuitry and a third communication circuitry.
