Abstract
A method of wireless communication includes receiving position location reference signals (PRSs) from multiple remote radio heads (RRHs) and a macro eNodeB having a same physical cell identity (PCI). Each PRS is a same PRS. Additionally, the PRSs from the multiple RRHs are received on subframes that are different from subframes used by the macro eNodeB. Furthermore, each PRS does not indicate a source of transmission. The method also includes determining a time difference between the received PRSs.
