1. A method for exploiting discontinuous reception (DRx) parameters to conserve power during an Observed Time Difference of Arrival (OTDOA) measurement session, comprising:

  • receiving, at a network server, information related to a DRx configuration associated with a user equipment (UE);

    selecting, at the network server, one or more inter-frequency base stations having inter-frequency Positioning Reference Signals (PRS) occasions that coincide with an OFF duration of the DRx configuration associated with the UE; and

    transmitting, by the network server to the UE, OTDOA assistance data that includes information related to the inter-frequency PRS occasions that coincide with the OFF duration of the DRx configuration associated with the UE.
