摘要： Repeated data packets are generated from a first Bluetooth enabled device to a second Bluetooth enabled device to facilitate radio direction finding of the first device by the second device. A communication connection is established between the first and second devices in accordance with a Bluetooth protocol stack and in response to receiving at the second device a data packet transmitted by the first device the second device transmits an NACK data packet to the first device, whereby the first device is cause to retransmit said data packet, and causing the second device to process at least one of the transmitted data packet and the retransmitted data packet in accordance with a radio direction finding algorithm. The communication connection preferably comprises a remote name request.

摘要： A co-existence method is described. The method comprises setting a priority level of a slot based on the likelihood that the slot will be required by a first radio and signalling the priority level to radio which is co-located with the first radio and which shares a resource with the first radio. The slot may, for example, be a re-transmission slot following a primary transmission slot or may be a sniff anchor point. The likelihood may be determined based on one or more factors, such as historical data or knowledge of the activity of a peer of the first radio.

摘要： A method of adjusting the transmission time of a signal in a radio link, the method being performed by a transmitter configured to transmit the signal over the radio link to a receiver and comprising the steps of ascertaining an accuracy that the receiver assumes for the transmitter's clock, calculating an assumed drift of the transmitter's clock based on the assumed accuracy of that clock and the time since a previous correlation between the transmitter's clock and the receiver's clock; and transmitting the signal at a time dependent on the assumed drift.
