1. A method of positioning performed by a receiver device, comprising:
measuring a time of arrival (ToA) of a positioning reference signal (PRS) transmission of a first PRS sequence transmitted by a first transmitter;
measuring a ToA of a PRS transmission of a second PRS sequence transmitted by a second transmitter; and
determining an observed time difference of arrival (OTDOA) between the PRS transmission of the first PRS sequence and the PRS transmission of the second PRS sequence as a difference between the ToA of the PRS transmission of the first PRS sequence and the ToA of the PRS transmission of the second PRS sequence,
wherein the OTDOA is less than a maximum differential delay expected between reception at the receiver device of a pair of PRS transmissions transmitted by a pair of transmitter devices during the same radio frame, and wherein a repetition duration of the first PRS sequence and the second PRS sequence is greater than 10 milliseconds (ms) and at least twice the maximum differential delay.
