3 Claims

1. A communication station comprising: a controller configured to: determine that a high priority communication is pending transmission to a user equipment (UE) device; determine that an unlicensed frequency band is in use; a licensed frequency band transmitter configured to transmit, in response to the controller, a high priority indicator within a licensed frequency band to at least another communication station, the high priority indicator indicating that the communication station has a high priority communication pending transmission; and unlicensed frequency band transmitter configured to transmit, in response to the controller determining that the unlicensed frequency band is not in use, the high priority communication over the unlicensed frequency band to the UE device, wherein the licensed frequency band transmitter is configured to transmit the high priority indicator within a downlink channel within the licensed frequency band.
