1. A method of performing positioning using a network, comprising:
- determining signal dimensions for an enhanced pilot from enhanced pilot information associated with a plurality of enhanced pilots, wherein the plurality of enhanced pilots include one or both of;
enhanced pilots transmitted by different sets of sectors in different sets of time slots, one set of time slots for each set of sectors;
orenhanced pilots transmitted by different sets of time frequency resources, one set of time frequency resources for each set of sectors;
receiving at a terminal the enhanced pilot information from the network; and
performing positioning of the terminal based on results of enhanced pilot measurements for multiple sectors using the enhanced pilot information from the terminal to obtain a position estimate for the terminal.

Abstract
Briefly, in accordance with one embodiment, a method of transmitting signals is provided. Signal waveforms are transmitted from at least two respective sectors. The at least two respective sectors are from at least two different sets of a superset of sectors. The transmitted signal waveforms include signal waveforms at least nearly mutually orthogonal at least along a particular signal dimension. An advantage of such an embodiment, for example, is reduced signal interference.
