Abstract: Disclosed are techniques for wireless communication. In an aspect, a first network node receives transmitter phase information from a second network node, the transmitter phase information including one or more parameters representing phase of a plurality of positioning reference signals (PRS) transmitted by at least one network node on a plurality of frequency intervals, and obtains positioning measurements of the plurality of PRS transmitted by the at least one network node based on the one or more parameters representing the phase of the plurality of PRS to enable a location of a user equipment (UE) to be determined based on at least the positioning measurements of the plurality of PRS.

Abstract: In an aspect, a location server may receive a request to determine a position of a first mobile device at a first scheduled time. The location server may determine a first position of a second mobile device during a first time window before the first scheduled time. The location server may configure the second mobile device to perform positioning operations during a second time window corresponding to the first scheduled time to assist in the determination of the position of the first mobile device at the first scheduled time.

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: Disclosed are techniques for communication. In an aspect, a UE reports a combination pattern for a combined measurement associated with samples across PRS occasions of a PRS measurement procedure. In another aspect, a UE reports a combined calibration error of a combined measurement associated with samples across PRS occasions of a PRS measurement procedure. The reported combination pattern and/or combined calibration error may be used by a position estimation entity for derivation of a position estimate of the UE.

Abstract: Techniques are provided for utilizing sidelink communications in response to a timing source outage. An example method for utilizing sidelink communications in response to a timing source outage according to the disclosure includes detecting the timing source outage associated with a first node, determining a second node experiencing a loss of services due to least in part on the timing source outage in the first node, determining a third node with a valid timing source, determining one or more relay nodes based at least in part on a location of the second node and a location of the third node, and providing one or more services to the second node via the one or more relay nodes.

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.
