Claim 14:
15. A method, comprising:
receiving, at a first communication device of a plurality of communication devices, at least one message from a second communication device of the plurality of communication devices over a preconfigured time duration;
determining, at the first communication device, a first local time of a clock of the first communication device at which the at least one message from the second communication device is received;
determining, at the first communication device, a sync-time of the second communication device based on the at least one message from the second communication device;
mapping, at the first communication device, the sync-time of the second communication device to a second local time of the clock of the first communication device based on the first local time, and the determined sync-time of the second communication device;
adjusting, at the first communication device, a sync-time of the first communication device based on the second local time; and
transmitting a first data or a second data as an acoustic signal for location positioning,
wherein the sync-time of the first communication device corresponds with a first configurable offset from a reference time, within which the first data is transmitted from the first communication device to the plurality of communication devices, and
wherein the sync-time of the second communication device corresponds with a second configurable offset from the reference time, within which the second data is transmitted from the second communication device to the plurality of communication devices.
