Abstract: Support for user equipment (UE) positioning with a non-terrestrial network (NTN) considers the significantly different propagation delays of positioning signals transmitted by SVs (SVs) in different orbits and elevation angles. The UE may be configured with a discontinuous measurement gap set for each positioning occasion, including separate measurement gaps for positioning signals transmitted by different SVs. Prioritization based on expected reference signal time differences (RSTD) may be used so that positioning signals received by the UE at nearly the same time are measured with higher priority. A burst configuration based on orbital position of SVs may be used so that positioning signals from different SVs will arrive at the UE within a maximum time window. The UE may provide a capability message indicating a maximum search window and uncertainty supported for NTNs, which may be used to configure the positioning signals to be measured by the UE.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a network entity may receive guard band information from each of a plurality of transmission/reception points (TRPs), wherein the guard band information describes guard bands used by that TRP. The network entity may generate assistance data, the assistance data comprising the guard band information for each of the plurality TRPs, wherein the guard band information defines at least one guard band between resource block (RB) sets within a bandwidth part (BWP), and wherein each guard band occupies zero or more contiguous RBs of the BWP. The network entity may send the assistance data to at least one user equipment (UE). In an aspect, the UE may then process positioning reference signals (PRSs) received from each of the plurality of TRPs according to the guard band information for that TRP.

Abstract: A wireless device may receive a configuration for a measurement of a set of reference signals (RSs). The set of RSs may include a first subset of RSs and a second subset of RSs. The wireless device may receive the set of RSs from a network node. The first subset of RSs may be associated with a first transmission (Tx) power setting and the second subset of RSs may be associated with a second Tx power setting. The first Tx power setting may be different from the second Tx power setting. The wireless device may measure the set of RSs. The wireless device may output the measured set of RSs for a training of a positioning model. The wireless device may include a user equipment (UE) or a positioning reference unit (PRU).

Abstract: Techniques are provided for utilizing a user equipment (UE) which is registered as a reference location device (RLD) and a location-target device. An example method of obtaining and reporting reference signal measurements includes providing an indication of a capability to operate as a reference location device and a location-target device, receiving assistance data associated with at least two positioning sessions occurring simultaneously, wherein a first positioning session is associated with the capability to operate as the reference location device and a second positioning session associated with the capability to operate as the location-target device, obtaining one or more reference signal measurements based at least in part on the assistance data, and reporting the one or more of the reference signal measurements to a positioning entity.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a wireless node establishes sidelink connections with a set of UEs. The wireless node transmits, to a network component, a request for sidelink resources for a sidelink position estimation procedure associated with the set of UEs. The network component determines an available sidelink resource pool for the sidelink position estimation procedure in response to the request. The network component transmits, to the wireless node in response to the request, an indication of the available sidelink resource pool for the sidelink position estimation procedure. The wireless node transmits, to each UE in the set of UEs, a sidelink resource configuration that is based on the available sidelink resource pool for the sidelink position estimation procedure.
