Samsung patents signal trick to improve phone location accuracy

Patent drawing
Patent drawing from the official filing.

Samsung has filed a patent for a method where phones send a copy of a location signal right before the main signal. This helps the network better separate signals from different devices that are sent at the same time.

Why it mattersThis could lead to slightly more accurate GPS-like positioning for phones in crowded areas where many devices are transmitting at once.

In the filing’s own words

A system and a method are disclosed for positioning. In some embodiments, the method includes transmitting, by a first User Equipment (UE): a first Positioning Reference Signal (PRS) transmission, and, immediately preceding the first PRS transmission, a duplicate of a symbol of the first PRS transmission, the duplicate and the first PRS transmission being in a same slot as: a second PRS transmission, multiplexed in time with the first PRS transmission, transmitted by a second UE, and, immediately preceding the second PRS transmission, a duplicate, of a symbol of the second PRS transmission, transmitted by the second UE.

What exactly they claim (claim 1)

1. A method, comprising: transmitting, by a first User Equipment (UE): a first Positioning Reference Signal (PRS) transmission, and, immediately preceding the first PRS transmission, a duplicate of a symbol of the first PRS transmission, the duplicate and the first PRS transmission being in a same slot as: a second PRS transmission, multiplexed in time with the first PRS transmission, transmitted by a second UE, and, immediately preceding the second PRS transmission, a duplicate, of a symbol of the second PRS transmission, transmitted by the second UE.
