Positioning using enhanced pilot signal

An apparatus for wireless communication, comprising:

• at least one processor configured to exchange at least one message between a terminal and a network server to exchange information for enhanced pilots used for positioning of the terminal, wherein the exchanged enhanced pilot information includes identification of at least a first plurality of sectors that transmit enhanced pilots and signal dimension information for the enhanced pilots associated with the sectors, the signal dimension information indicating at least nearly mutually orthogonal signal dimensions, and to perform positioning based on the exchanged enhanced pilot information to obtain a position estimate for the terminal.
