Claim of US Patent No. 10,893,482
1. A wireless station, comprising:at least one antenna;
one or more wireless interfaces in communication with the at least one antenna; and
at least one processor in communication with the one or more wireless interfaces;
wherein the at least one processor is configured to cause the wireless station to:
determine, for a first discovery channel, an average channel interference;
select, when the average channel interference is less than a first threshold, a first transmission mode having an associated first power level;
determine a maximum data rate for the first transmission mode;
perform, when the maximum data rate satisfies a quality of service requirement for a device-to-device transmission, a device-to-device transmission with a neighboring wireless device using the first transmission mode; and
in response to detecting an out-of-band triggering event, transmit a plurality of consecutive discovery beacons to the neighboring wireless device, wherein each consecutive discovery beacon of the plurality of consecutive discovery beacons is transmitted at a respective power level.
one or more wireless interfaces in communication with the at least one antenna; and
at least one processor in communication with the one or more wireless interfaces;
wherein the at least one processor is configured to cause the wireless station to:
determine, for a first discovery channel, an average channel interference;
select, when the average channel interference is less than a first threshold, a first transmission mode having an associated first power level;
determine a maximum data rate for the first transmission mode;
perform, when the maximum data rate satisfies a quality of service requirement for a device-to-device transmission, a device-to-device transmission with a neighboring wireless device using the first transmission mode; and
in response to detecting an out-of-band triggering event, transmit a plurality of consecutive discovery beacons to the neighboring wireless device, wherein each consecutive discovery beacon of the plurality of consecutive discovery beacons is transmitted at a respective power level.
