1. A wireless transceiver of a base station in communication with one or more remote transceivers in a network coexisting with a user having associated non-cooperative transmissions, the wireless transceiver comprising:

  • a radio transceiver transferring data between active ones of the remote transceivers during slots of a first time period in one of a plurality of channels of a secondary network; and

    a controller to coordinate the transfer of data between the active ones of the remote transceivers, to synchronize each time period between the one or more remote transceivers via a message providing a time frame having a format, and to select one of the plurality of channels to operate the secondary network;

    wherein the controller, via the radio transceiver, communicates to the active ones of the remote transceivers to suspend transmissions during gaps in a second time period in a monitored one of the plurality of channels;

    wherein the controller, coupled to the radio transceiver, asynchronously monitors and detects a presence or an absence of the non-cooperative transmissions within the monitored one of the plurality of channels during the gaps, andwherein the time frame format includes timing information of each gap in the second time period.
