Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) identifies a set of positioning sources, each positioning source comprising a positioning reference signal (PRS) resource, a PRS resource set, a PRS frequency layer, and/or a transmission/reception point (TRP). From the set of positioning sources, the UE identifies a consistency group comprising a collection of positioning sources grouped based on expected values of at least one metric of a reference signal from each positioning source, measured values of the at least one metric for the reference signal from each positioning source, and an error threshold. The UE identifies one or more subsets of positioning sources within the consistency group, each subset having at least one metric error value. The UE reports, to a network entity, information about the consistency group and information about at least one of the subsets of positioning sources within the consistency group.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a UE determines old and new pathloss vectors that track old and new pathloss values on an element-specific basis. For a respective element, the UE selectively triggers a PHR based upon respective old and new pathloss values for that element. In another aspect, the UE determines whether differential pathloss value between two respective pathloss values associated with two pathloss measurement attempts for an element is unavailable or (if available) is higher than a threshold value, and the UE selectively triggers a PHR for the element based on the determination.

Abstract: Frequency-dependent changes in beam shapes of transmitted RF signals can be provided to a receiving device. Beam shape information can include, for example, gain of a beam and a plurality of azimuth and elevation directions, boresight and width of a main lobe (and optionally side lobes) of the beam, information regarding a pattern of antenna elements of an antenna panel used to transmit the beam, and/or similar information. The type of information provided can dictate the amount of overhead required, and we therefore vary depending on the means by which the information is conveyed. Additional detail is provided in the embodiments described herein.

Abstract: Techniques are provided for handling positioning sessions in response to a timing source outage. An example method for configuring a positioning method based on a timing source outage includes receiving an indication of the timing source outage from a station, determining the positioning method based at least in part on the indication of the timing source outage, and sending an indication of the positioning method to one or more network entities.

Abstract: Aspects of the disclosure relate to determining channel state information (CSI) on a component carrier. In an example operation, a device determines a mapping between first time-frequency resources corresponding to a first component carrier (CC) and second time-frequency resources corresponding to a second CC using a prediction algorithm. The device receives, from a base station, a channel state information reference signal (CSI-RS) on the first time-frequency resources corresponding to the first CC and measures first CSI on the first time-frequency resources corresponding to the first CC based on the received CSI-RS. The device further predicts second CSI on the second time-frequency resources corresponding to the second CC based on the measured first CSI using the prediction algorithm. The device then generates a CSI report based on the predicted second CSI and sends the CSI report to the base station.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a positioning entity determines an initial set of wireless links over which positioning reference signals (PRS) are measured by a network node engaged in a positioning session, identifies a subset of wireless links of the initial set of wireless links based on an expected positioning measurement associated with a corresponding wireless link of the initial set of wireless links, a location of an anchor node associated with the corresponding wireless link, and an observed positioning measurement for the corresponding wireless link, and determines a location of the network node based on observed positioning measurements of the identified subset of wireless links.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a position determination entity (PDE) receives a request to schedule an on-demand PRS positioning session of a UE at a future time, wherein the request is configured to request a first set of parameters for the scheduled on-demand PRS positioning session, with an availability of one or more parameters of the first set of parameters at the future time being indeterminable when the request is received. PDE determines the availability of the one or more parameters at the future time. PDE determines a PRS configuration for the scheduled on-demand PRS positioning session in advance of the future time.
