Patent ID: 7920544

Claim:
In a time division multiplex communication system, a method of distributing position location signals, the method comprising: determining a timing, according to a time reference, of a synchronized position location slot, wherein the synchronized position location slot includes: a plurality of sub-slots assigned to a plurality of position location signal sources; and an identifier indicating that the synchronized position location slot includes position location information; assigning to a first signal source, a first sub-slot within the synchronized position location slot with a first position location signal corresponding to the first signal source from the plurality of position location signal sources; causing the transmission, from the first signal source, of the synchronized position location slot having the first position location signal and a blank sub-slot in at least a second sub-slot of the synchronized position location slot; assigning to a second signal source a second sub-slot distinct from the first sub-slot with a second position location signal corresponding to the second signal source from the plurality of position location signal sources; and causing the transmission, from the second signal source, of the synchronized position location slot having the second position location signal and a blank sub-slot in at least the first sub-slot of the synchronized position location slot.
