  • Patent number: 11808870
    Abstract: The disclosure relates to an OTDOA positioning technique wherein different base stations transmit different variations of the same basic PRS or other positioning signal synchronously as an SFN signal to effect an observed time shift at the UE between the different variations of the basic PRS signal or positioning signal. This added time shift resulting from the transmission of different variations by different base stations effectively spreads the corresponding channel impulses in the CIR of the SFN signal in the time domain so that the UE is better able to detect and discriminate between different instances of the positioning signal transmitted from different base stations.
