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: Techniques are provided for managing positioning reference signals in communication networks. An example method of measuring downlink positioning reference signals includes transmitting one or more uplink positioning reference signals, receiving downlink positioning reference signal configuration information associated at least in part with the one or more uplink positioning reference signals, and measuring one or more downlink positioning reference signals based at least in part on the downlink positioning reference signal configuration information.

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: In an aspect, a first UE transmits SL-PRS to a second UE based on a bandwidth associated with DL-PRS(s) from one or more gNBs to the second UE in association with a positioning procedure of the second UE. In other aspects, a network component (e.g., LMF UE, etc.) triggers transmission of a WLAN ranging signal from a first UE to a second UE (e.g., to supplement an NR-based positioning procedure).

Abstract: According to embodiments herein, a UE can be configured with a spatial relationship for an Uplink Position Reference Signal (UL-PRS) to transmit via the SL interface. This information can include various options related to a transparent mode in which an anchor UE connected with the UE via the SL interface generally acts like a base station. In an advanced mode, any of a variety of aspects of the SL interface used in communication between the UE and anchor UE may be used as a reference for UL-PRS.

Abstract: A positioning signal processing method at a user equipment includes: operating the user equipment in a discontinuous reception mode including time interleaved ON times of the discontinuous reception mode, during which the user equipment is in an active mode monitoring for a positioning signal measurement trigger signal, and OFF times of the discontinuous reception mode, during which the user equipment is in an inactive mode; receiving a wake-up signal at the user equipment; and determining, at the user equipment, whether to measure a positioning signal based on whether the wake-up signal indicates to implement the active mode during a scheduled discontinuous reception mode ON time or to skip the scheduled discontinuous reception mode ON time.

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.
