Positioning reference signal (PRS) generation for multiple transmit antenna systems
First Claim
1. A processor-implemented method of generating a Positioning Reference Signal (PRS) sequence, the method comprising:
- assigning 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
generating a plurality of PRS sequences, each PRS sequence in the plurality of PRS sequences corresponding to a distinct physical transmitting antenna element in the plurality of physical transmitting antenna elements, wherein each PRS sequence has a corresponding frequency shift based, at least in part, on a corresponding PAP ID (h) of a corresponding physical transmitting antenna element.
