Abstract: Disclosed are techniques related to wireless communication. In an aspect, a sequence generating entity factorizes a comb size N into prime factors of N, and generates one or more offset sequences for a reference signal for positioning based on one or more sequence lists associated with the prime factors of N and a number of symbols M over which the reference signal is scheduled.

Abstract: A method of performing positioning operations at a user equipment includes: operating the user equipment in a discontinuous reception mode including time interleaved ON times of the discontinuous reception mode and OFF times of the discontinuous reception mode, where the time interleaved ON times defines an ON time window of the discontinuous reception mode; and determining, at the user equipment, whether to measure a portion of a positioning signal based on timing of the portion of the positioning signal relative to at least one of a first one of the ON times of the discontinuous reception mode or a first one of the OFF times of the discontinuous reception mode.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a relative location anchor group (RLAG) may facilitate a position estimation procedure in an environment where absolute position estimation accuracy is below a threshold. An absolute position estimate derived via the RLAG may optionally be transformed to a true (or more accurate) position estimate via transformation information. In some cases, new anchors may be added to the RLAG after performing a position estimation procedure with the RLAG. In other designs, a local coordinate system (LCS) may be used for position estimation in lieu of a global coordinate system (GCS), such as WGS 84.

Abstract: Aspects presented herein may enable a UE to perform positioning using virtual anchors and/or positioning reference units. In one aspect, a UE transmits a request for assistance data for performing UE-based positioning, where the request includes at least one of location information of the UE or a list of anchors observed by the UE. The UE receives the assistance data for the UE-based positioning, where the assistance data includes a list of virtual anchors and a list of positioning reference units (PRUs) that includes a set of virtual PRUs (VPRUs), where the list of virtual anchors and the list of PRUs are selected based on at least one of the location information of the UE or the list of anchors observed by the UE. The UE performs the UE-based positioning using at least one virtual anchor and at least one VPRU in the assistance data.

Abstract: A position information reporting method includes: communicating by a first UE with a second UE to identify a first PRS measurement to be made by the second; receiving, by the first UE from the second UE via sidelink communication, first position information based on the first PRS measurement; and transmitting, from the first UE to a network entity, the first position information.

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: An aspect is directed to signaling, to a target UE, a required reference signal for positioning (RS-P) measurement set and an optional RS-P measurement set (e.g., for a positioning session associated with a DDT procedure or a non-DDT procedure). In another aspect, a double differential timing (DDT) procedure is triggered based at least upon a trajectory of a target user equipment (UE). Another aspect is directed to a joint DDT (J-DDT) procedure involving multiple reference wireless nodes.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a first network node receives a measurement request from a location server, the measurement request requesting the first network node to measure a positioning reference signal (PRS) resource from at least one second network node using a plurality of receive timing error groups (Rx TEGs) of the first network node, and transmits a measurement report to the location server, the measurement report including a plurality of positioning measurements based on the PRS resource, the plurality of positioning measurements corresponding to the plurality of Rx TEGs.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may receive, from a network node, at least one positioning reference signal (PRS) configuration that defines or indicates a plurality of PRS resources having unique identifiers, the plurality of PRS resources comprising a first set of one or more PRS resources, wherein each of the one or more PRS resources in the first set is mapped to an associated identifier used by all UEs served by a location server to identify an associated PRS resource. The UE may perform a positioning operation according to the at least one PRS configuration.
