    Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives a positioning reference signal (PRS) configuration, the PRS configuration including at least a PRS periodicity defining repetitions of one or more PRS resources associated with at least a first transmission-reception point (TRP), receives a measurement gap configuration including at least a measurement gap repetition period (MGRP) defining repetitions of a measurement gap, and performs one or more positioning measurements of at least the one or more PRS resources during one or more repetitions of a measurement period, the one or more repetitions of the measurement period having an effective measurement periodicity, the effective measurement periodicity based on an alignment periodicity and a time period T during which the UE can process a duration N of PRS symbols, the alignment periodicity based on the PRS periodicity and the MGRP.

    Abstract: Methods, apparatuses, and devices for processing Positioning Reference Signals (PRS) bursts are presented. In one example, a mobile device may acquire a first PRS burst transmitted from a base station through first transmitter antenna port and acquire a second PRS burst transmitted from a base station through a second antenna port. The mobile device may select between the first and second acquired PRS bursts for use in positioning operations such as observed time difference of arrival.

    Abstract: Techniques are provided, which may be used for determining a position of a user equipment (mobile device). In certain example implementations, tones in positioning signals from one or more sources that may interfere with certain positioning signals be estimated and some form of interference mitigation may be applied, which may better enable the user equipment to acquire certain other positioning signals that may be useful in determining a position of the user equipment.

    Abstract: Described are an apparatus and a method for increasing an uncertainty associated with an estimated position of the apparatus. Signals transmitted from a plurality of stationary transmitters may be acquired, and a difference in received carrier frequency of the acquired signals may be measured. The lower bound of a speed of a mobile device may be determined based at least in part on the measured difference in received carrier frequency. The uncertainty may be increased based at least in part on the lower bound of the speed.

    Abstract: Disclosed are techniques for wireless communication. In an aspect, a network node performs one or more positioning measurements of one or more types of positioning measurements of one or more reference signals, and reports, to a positioning entity, the one or more positioning measurements and one or more measurement quality values representing a measurement quality of the one or more positioning measurements, the one or more measurement quality values based on measurement quality reporting parameters, wherein the measurement quality reporting parameters comprise a minimum error value, a maximum error value, a number of bits used for the one or more measurement quality values, a scaling function or an identifier of the scaling function, or any combination thereof.
