Abstract
A circuit includes a first wireless interface circuit that transceives packetized data with a first external device in accordance with a first wireless communication protocol. A second wireless interface circuit transceives packetized data with a second external device in accordance with a second wireless communication protocol and wherein the operation of the second wireless interface circuit interferes with the operation of the first wireless interface circuit. A processing module selectively preempts use of the second frequency spectrum by the second external device using a plurality of preemption modes including a first preemption mode and a second preemption mode.
Claims22
A circuit comprises:
- a first wireless interface circuit that transceives packetized data with a first external device in accordance with a first wireless communication protocol;
- a second wireless interface circuit that transceives packetized data with a second external device in accordance with a second wireless communication protocol and wherein operation of the second wireless interface circuit interferes with operation of the first wireless interface circuit;
- and
- a processing module, coupled to the first wireless interface circuit and the second wireless interface circuit, that selectively preempts transmissions by the second external device to the second wireless interface circuit using a plurality of preemption modes including a first preemption mode and a second preemption mode;
- wherein the second wireless communication protocol includes a wireless local area network protocol that includes a power saving mode and wherein the first preemption mode preempts transmissions by the second external device by causing the second wireless interface circuit to transmit packetized data to the second external device that includes a power save mode indication.
A method comprises:
- transceiving packetized data with a first external device in accordance with a first wireless communication protocol;
- transceiving packetized data with a second external device in accordance with a second wireless communication protocol that can interfere with the transceiving of packetized data with the first external device;
- and
- selectively preempting transmissions by the second external device using a plurality of preemption modes including a first preemption mode and a second preemption mode;
- wherein the second wireless communication protocol includes a wireless local area network protocol and wherein the second preemption mode preempts transmissions by the second external device by transmitting packetized data to the second external device that includes a self clear to send indication.
