Abstract
A first device in a short-range wireless piconet self-learns a multi-frame piconet pattern that is used by a second device as a result of a deferral that reduces or avoids simultaneous transmission and reception by two transceivers at the second device. The first device uses this self-learned multi-frame piconet pattern to selectively control transmitting and receiving by the first device. Power can thereby be conserved at the first device. Related devices, networks and methods are described.

A method of operating a first device that communicates with a second device in a short-range wireless piconet comprising:
- determining at the first device a multi-frame piconet pattern comprising at least two different piconet slot positions that are used by the second device to transmit to the first device in at least two different piconet frames and/or at least two different piconet slot positions that are used by the second device to receive from the first device in at least two different piconet frames;
- and
- selectively controlling transmitting and/or receiving by the first device in response to the multi-frame piconet pattern that was determined by the first device so that the first device selectively transmits to the second device during the at least two different piconet slot positions in the at least two different piconet frames that were determined to be used by the second device to receive from the first device and/or the first device selectively receives from the second device during the at least two different piconet slot positions in the at least two different piconet frames that were determined to be used by the second device to transmit to the first device.
A first device that communicates with a second device in a short-range wireless piconet, the first device comprising:
- a multi-frame piconet pattern recognizer that is configured to determine a multi-frame piconet pattern comprising at least two different piconet slot positions that are used by the second device to transmit to the first device in at least two different piconet frames and/or at least two different piconet slot positions that are used by the second device to receive from the first device in at least two different piconet frames;
- and
- a first device transceiver that is configured to selectively transmit to the second device during the at least two different piconet slot positions in the at least two different piconet frames that were determined by the pattern recognizer to be used by the second device to receive from the first device and/or to selectively receive from the second device during the at least two different piconet slot positions in the at least two different piconet frames that were determined by the pattern recognizer to be used by the second device to transmit to the first device.
A method of operating a second device that communicates with a first device in a short-range wireless piconet comprising:
- selectively refraining from transmitting to the first device concurrent with receiving over a wide area wireless network;
- and/or
- selectively refraining from receiving from the first device concurrent with transmitting over the wide area wireless network to thereby produce a multi-frame piconet pattern comprising at least two different piconet slot positions that are used by the second device to transmit to the first device in at least two different piconet frames and/or at least two different piconet slot positions that are used by the second device to receive from the first device in at least two different piconet frames.
