Abstract

Methods having corresponding apparatus and computer-readable media comprise: transmitting and receiving wireless Long Term Evolution (LTE) signals according to an LTE schedule; transmitting and receiving wireless Bluetooth signals according to a Bluetooth schedule having a plurality of Bluetooth schedule slots, wherein the wireless Bluetooth signals represent Bluetooth Asynchronous Connection-oriented (ACL) logical transport packets; generating a Bluetooth ACL packet; selecting a spoofed number M of the Bluetooth schedule slots for the Bluetooth ACL packet based on information representing the LTE schedule, wherein M is a positive integer; selecting a Bluetooth ACL packet type based on the spoofed number M of the Bluetooth schedule slots; and indicating the selected Bluetooth ACL packet type in a type field of the Bluetooth ACL packet prior to transmitting the wireless Bluetooth signals representing the Bluetooth ACL packet.

Claims17

Dependent claims

An apparatus comprising:

a Long Term Evolution (LTE) transceiver configured to transmit and receive wireless LTE signals according to an LTE schedule, and to provide LTE schedule information that represents the LTE schedule;
a Bluetooth transceiver configured to transmit and receive wireless Bluetooth signals according to a Bluetooth schedule having a plurality of Bluetooth schedule slots, wherein the wireless Bluetooth signals represent Bluetooth Asynchronous Connection-oriented (ACL) logical transport packets;
a Bluetooth packetizer configured to generate a Bluetooth ACL packet, wherein the Bluetooth ACL packet generated by the Bluetooth packetizer requires only N of the Bluetooth schedule slots, wherein N is a positive integer;
and
a Bluetooth scheduler configured to (i) determine a spoofed number M of the Bluetooth schedule slots for the Bluetooth ACL packet based on (i) the LTE schedule information and (ii) the integer N, and (ii) select the spoofed number M of the Bluetooth schedule slots for the Bluetooth ACL packet based on the LTE schedule information, wherein M is a positive integer, and wherein M>N,
wherein the Bluetooth packetizer is further configured to select a Bluetooth ACL packet type based on the spoofed number M of the Bluetooth schedule slots, and to indicate the selected Bluetooth ACL packet type in a type field of the Bluetooth ACL packet, prior to the Bluetooth transceiver transmitting the wireless Bluetooth signals representing the Bluetooth ACL packet.
