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.

Abstract: A method includes obtaining a first power measurement associated with resource blocks (RBs) being utilized by a terminal device (TD). The method includes determining whether the first power measurement satisfies a first threshold. The method includes, upon determining that the first power measurement satisfies the first threshold, transmitting, to a target TD, a positioning reference signal (PRS). The method includes, determining whether the first power measurement does not satisfy the first threshold and, in response, determining a set of comb parameters. The method includes obtaining, based on the set of comb parameters, a second power measurement associated with resource elements (REs) related to the RBs. The method includes determining whether the second power measurement satisfies a second threshold. The method includes, upon determining that the second power measurement satisfies the second threshold, transmitting, based on the set of comb parameters, the PRS to the target TD.

Abstract: A method, apparatus and computer program product are provided for aligning the reporting of timing measurements and corresponding carrier phase (CP) measurements to avoid CP measurement error due to stale timing measurement information. In the context of a method, the method includes receiving, at a user equipment (UE), a request to maintain time separation between respective timestamps of carrier phase (CP) measurements and timing measurements within a predefined timing separation threshold. The method further includes generating, at the UE, at least one DL CP measurement associated with at least one timestamp, and at least one DL timing measurement associated with at least one DL timing measurement timestamp based on the predefined timing separation threshold, wherein a timing separation between the at least one timestamp and the at least one DL timing measurement timestamp is within the predefined timing separation threshold.

Abstract: Techniques are provided for mitigating measurement errors for carrier phase positioning due to hardware impairments. In the context of a method performed by user equipment, the method includes causing transmission of a message to request a gNB to provide at least one sounding reference signal (UL SRS) configuration satisfying a phase error less than a threshold value associated with a UE transmission phase error group identifier (UE Tx PEG ID). The method also includes receiving at least one sounding reference signal (UL SRS) configuration in response to the request. The method further includes causing SRS transmission using UL SRS resources based upon the UL SRS configuration provided by the gNB. Corresponding methods, apparatus and computer-readable storage mediums are provided for location management function (LMF) and gNB for uplink and downlink configurations.
