Abstract:
A position reference signal (PRS) to support observed time difference of arrival (OTDOA) position determination in an electronic device is generated and transmitted by a network node that has a unique identifier. Generating the PRS includes generating a first PRS sequence and generating a second PRS sequence by modifying the first PRS sequence with a modification function to generate the second PRS sequence. A sum of the first PRS sequence and the second PRS sequence is zero.
