Disclosed aspects and embodiments pertain to conserving power usage during an Observed Time Difference of Arrival (OTDOA) measurement session. For example, a server or other network entity may receive information related to a Discontinuous Reception (DRx) or Connected Mode DRx (CDRx) configuration associated with a user equipment (UE) and provide, to the UE, information related to one or more base stations having Positioning Reference Signal (PRS) occasions that coincide with an OFF state associated with the DRx/CDRx configuration. Alternatively and/or additionally, the UE may receive OTDOA assistance information indicating when certain PRS occasions occur and a serving base station or other network entity may provide the UE with a DRx/CDRx configuration having an OFF state that coincides with the PRS occasions. As such, the DRx/CDRx parameters may be exploited to substantially reduce or eliminate measurement gaps and conserve power usage during an OTDOA session.
