Abstract: Systems, methods, apparatuses, and computer program products for reporting LO information for RTT carrier phase positioning. An apparatus includes at least one processor and at least one memory storing instructions that, when executed by the at least one processor, may cause the apparatus at least to determine a local oscillator in the apparatus that is used to perform at least one downlink positioning reference signal (PRS) measurement and at least one uplink sounding reference signal (SRS) transmission; and transmit local oscillator information comprising at least one identifier associated with the determined local oscillator to a first network entity.

Abstract: When discontinuous reception is used with positioning and reference signals for positioning are received in a plurality of frequency bins, it may be that a frequency bin is missed. That may decrease an accuracy of the positioning. Hence, an apparatus receiving the reference signals, when determining that one or more frequency bins are missed, may use, when one or more conditions are met, earlier values per a missed frequency bin, when estimating at least one characteristic for positioning.

Abstract: Systems, methods, apparatuses, and computer program products for non-stationary carrier-phased positioning (CPP). A method may include receiving an indication to transmit a sounding reference signal or a carrier phase positioning measurement. The indication may include at least a phase pre-compensation on the sounding reference signal transmission or a correction of the carrier phase positioning measurement based at least on a Doppler shift. The method may also include performing, at a user equipment, the phase pre-compensation for the sounding reference signal transmission, or the correction of the carrier phase positioning measurement. The method may further include transmitting, by the user equipment, the sounding reference signal with the phase pre-compensation or the carrier phase positioning measurement.
