1. A method of transmitting signals comprising:

  • transmitting Position Location Pilot (PLP) signal waveforms from at least two respective sectors, said at least two respective sectors being from at least two different sets of a superset of sectors, the transmitted signal waveforms comprising signal waveforms at least nearly mutually orthogonal at least along a particular signal dimension, wherein each set includes a plurality of sectors having a signal waveform associated with the same particular signal dimension, and wherein said plurality of sectors are assigned a plurality of respective PLP zones, each of the sectors capable of re-using at least one segment of said signal dimension, wherein the PLP signal waveforms are transmitted in bursts in predetermined time slots within each of a plurality of time frames, and wherein each of the PLP signal waveforms occupies a different time slot within each of two immediately adjacent time frames.
