Positioning reference signal (PRS) generation for multiple transmit antenna systems

An apparatus comprising:

• a transceiver, the transceiver capable of transmitting Positioning Reference Signal (PRS) information;
• and
• a processor coupled to the transceiver, the processor configured to:
• assign a distinct Physical Antenna Port (PAP) identifier (ID) to each physical transmitting antenna element in a plurality of physical transmitting antenna elements serving a single cell;
• and
• generate a plurality of distinct PRS sequences, each distinct PRS sequence in the plurality of distinct PRS sequences corresponding to a distinct physical transmitting antenna element in the plurality of physical transmitting antenna elements.
