A method for use in determining a position of a mobile device in a wireless communication network includes acquiring, by the mobile device, a first positioning signal transmitted at a first frequency and a second positioning signal transmitted at a second frequency that is different than the first frequency. The mobile device performs a first measurement of a time difference of arrival between the first positioning signal and the second positioning signal. In certain implementations, in response to a determination to not apply an inter-frequency bias compensation to the first measurement for inter-frequency related delays corresponding to the first frequency, the second frequency, or both the first frequency and the second frequency, the mobile device sends the first measurement and a first measurement description to a server to determine the position of the mobile device. The first measurement description indicates that the first measurement has not been compensated for the inter-frequency related delays.
