Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives, from a network entity, a request to provide a UE transmit (Tx) timing error group (TEG) report for an uplink-only positioning procedure, transmits one or more uplink sounding reference signal (UL-SRS) resources of at least one UL-SRS resource set during the uplink-only positioning procedure, and transmits the UE Tx TEG report to the network entity, the UE Tx TEG report including at least one UE Tx TEG associated with the transmission of the one or more UL-SRS resources of the at least one UL-SRS resource set, the at least one UE Tx TEG indicating that transmit timing errors of the transmission of the one or more UL-SRS resources of the at least one UL-SRS resource set are within a margin.

Abstract: Disclosed are techniques for communication. In an aspect, a position estimation entity determines a sidelink positioning reference signal (SL-PRS) resource configuration associated with a positioning measurement procedure. The position estimation entity transmits an indication of the SL-PRS resource configuration (e.g., to first and/or second UEs). The UE(s) obtain the SL-PRS resource configuration, and perform the positioning measurement procedure in accordance with the SL-PRS resource configuration.

Abstract: Disclosed are systems, methods, and non-transitory media for detecting a positioning attack based on wireless position signaling. For example, a location server can determine a positioning reference signal having at least a first signal portion and at least a second signal portion. An indication of a positioning attack associated with the positioning reference signal can be obtained. The location server can provide, to a base station, a message of transmission preemption of the second signal portion of the positioning reference signal based on the indication of the positioning attack.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor a set of frequencies in a frequency band for a synchronization signal block (SSB) according to an initial channel raster. The initial channel raster may be associated with an initial cell or an initial base station. The UE may receive an indication of one or more frequencies for an updated channel raster associated with another cell or another base station. The initial channel raster and the updated channel raster may be different. The UE may monitor for another SSB according to the updated channel raster, which may include additional frequencies within a same frequency band or a different frequency band.

Abstract: Disclosed are techniques for communication. In an aspect, a position estimation entity (e.g., gNB, LMF, location server, UE, etc.) determines a paired downlink positioning reference signal (DL-PRS) resource configuration for a first DL-PRS and a second DL-PRS that is offset in time from the first DL-PRS by a time offset, the first and second DL-PRSs associated with the same transmission source. The position estimation entity transmits the paired DL-PRS resource configuration to a UE, which performs measurements in accordance with the paired DL-PRS resource configuration.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a first user equipment (UE) may determine that a resource pool for positioning (RPP) from a predefined plurality of RPPs should be reserved, and transmit, to at least one other UE, a reservation message indicating reservation of a RPP from the predefined plurality of RPPs. The RPP may be reserved for use by the first UE or, if the first UE is a relay UE, for use by a remote UE served by the relay UE. The reservation message may be broadcast, groupcast, multicast, etc. In response to receiving the reservation message indicating reservation of a RPP from a predefined plurality of RPPs, the at least on other UE may modify an intended transmission to reduce interference during the reserved RPP.

Abstract: Motion detection services are performed in a wireless network (e.g., a cellular network) with reference to beamforming. Reference signals or other resources for motion detection based on RAdio Detection And Ranging (RADAR) are transmitted over one or more transmit beams or received over one or more receive beams. Any motion measured from reflections of the signals may be associated with one or more of the transmit or receive beams. A device configured to receive the reflections determines one or more motion measurements associated with one or more beams, and determines one or more motion state metrics associated with the one or more beams. The one or more motion state metrics are included in one or more motion state reports to a network entity (e.g., a radar server), which may be used for various operations in the wireless network.

Abstract: A user equipment (UE) obtains assistance data for positioning from one or more sidelink connected UEs. Prior to sending the assistance data for positioning to the UE, the sidelink UE(s) revises the assistance data, e.g., by reprioritizing, reordering, or reducing the assistance data, or a combination thereof. By revising the assistance data the sidelink UE(s) provides the most pertinent assistance data to the UE, thereby increasing power savings for the UE. Where multiple sidelink UEs provide revised assistance data to the UE, the UE combines the revised assistance data, e.g., based on measurement information, range information, or priority of the sidelink UEs. If the UE has a connection to the location server, the UE obtains revised assistance data from sidelink UE(s) to avoid the need for an assistance data exchange with the location server during the positioning session, thereby improving latency.

Abstract: Disclosed are systems, apparatuses, methods, and non-transitory media for facilitating positioning reference signal (PRS) prioritization by receiving beam index information associated with a PRS beam set. In some aspects, an assigned beam can be determined based on the beam index information. At least one adjacent beam can further be determined to be based on the assigned beam associated with the beam index information. A location measurement can also be determined based on at least one of the assigned beam, or the at least one adjacent beam.
