1. A wireless electronic device, comprising:

  • an antenna;

    a transceiver circuit coupled to the antenna;

    a radio-frequency diplexer coupled to the antenna; and

    a first baseband processor coupled to the transceiver circuit, wherein the first baseband processor operates in a sleep state from which the first baseband processor awakens for a first wake period, and the first baseband processor is configured to;

    monitor for a first paging signal associated with the first baseband processor during the first wake period; and

    in response to the first paging signal being absent during the first wake period, generate control signals to cause a second baseband processor coupled to the antenna in the wireless electronic device to avoid collisions between the first wake period of the first baseband processor and a second wake period of the second baseband processor, wherein the control signals are generated based at least in part on a predetermined amount of time that expires at an approximate midpoint between successive slots of a first cycle associated with the first wake period.
