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: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) identifies a set of positioning sources, each positioning source comprising a positioning reference signal (PRS) resource, a PRS resource set, a PRS frequency layer, and/or a transmission/reception point (TRP). From the set of positioning sources, the UE identifies a consistency group comprising a collection of positioning sources grouped based on expected values of at least one metric of a reference signal from each positioning source, measured values of the at least one metric for the reference signal from each positioning source, and an error threshold. The UE identifies one or more subsets of positioning sources within the consistency group, each subset having at least one metric error value. The UE reports, to a network entity, information about the consistency group and information about at least one of the subsets of positioning sources within the consistency group.

Abstract: In an aspect, a relay UE transmits sidelink reference signals for positioning (SL-RS-P) off first and second reconfigurable intelligent surfaces (RISs). The target UE measures the reflected SL-RS-Ps. In an aspect, the SL-RS-Ps may be associated with configurations that are configured by a base station. In an aspect, a position estimation entity may obtain measurement information associated with the reflected SL-RS-Ps and determine a position estimate of the target UE based at least in part upon the measurement information.

Abstract: In some implementations, a base station may send, to a user equipment (UE), a message indicating that an RF sensing signal is to be used for the RF sensing, wherein the message indicates: the RF sensing signal comprises a modified synchronization signal block (SSB) for supporting both sensing and initial access/mobility, or the RF sensing signal comprises a non-SSB sensing reference signal (S-RS) of a secondary cell (Scell) and has a quasi co-location (QCL) relationship with a root SSB of a primary cell (Pcell). The base station also may transmit the RF sensing signal.

Abstract: Techniques for communication by a user equipment (UE) are disclosed. Techniques can include determining a positioning state information (PSI) report to transmit, where the PSI report comprises positioning-related information, and selecting a physical uplink control channel (PUCCH) resource with which to transmit the PSI report, where the selected PUCCH resource comprises a number of resource blocks (RBS). Techniques can further include determining whether to transmit the PSI report using the selected PUCCH resource, based on: the number of RBS, a size of uplink control information (UCI) to be transmitted using the selected PUCCH resource, the selected PUCCH resource being configured with a capability to include both the PSI report and a hybrid automatic repeat request acknowledgment (HARQ-ACK), or the selected PUCCH resource being configured to include only one or more PSI reports, and optionally one or more CSI reports, as a payload, or any combination thereof.

Abstract: Disclosed are techniques for communication. In an aspect, a wireless node (e.g., UE or BS) measures a first TOA of a first SRS-P from a UE, a second TOA of a reflection of a second SRS-P from the UE off of a first RIS, and a third TOA of a reflection of a third SRS-P from the UE off of a second RIS. The UE transmits, to a position estimation entity, measurement information based on the first, second and third TOAs. The position estimation entity determines a positioning estimate of the UE based at least in part on the measurement information.

Abstract: Techniques for reconfigurable intelligent surface (RIS)-assisted calibration for timing errors in wireless nodes may comprise obtaining a set of wireless reference signal measurements comprising: first, second, third, and fourth measurements of reference signals traveling between the mobile device, a first wireless node, and a second wireless node, wherein a portion of the reference signals are reflected by the RIS while traveling between the mobile device and the first or second wireless node. A differential value comprising a difference between the third measurement and the fourth measurement is also obtained. Determining a position estimate of the mobile device may then be performed, based at least in part on the set of wireless reference signal measurements, the differential value, and a respective location of each of the first wireless node, the second wireless node, and the RIS.

Abstract: In an aspect, a location of a reference UE is obtained (e.g., iteratively). A first differential RTT measurement is determined based on RTTs between a target UE and each of first and second wireless nodes, and a second differential RTT measurement is determined based on RTTs between a reference UE and each of the first and second wireless nodes. A positioning estimate of the target UE is determined based on the first and second differential RTT measurements and the obtained reference UE location (e.g., a most recent of the iteratively obtained reference UE locations). In another aspect, a primary reference UE among a plurality of reference UEs is selected, and its location is obtained (e.g., iteratively). A location of other reference UE(s) is determined based at least in part upon the obtained primary reference UE location (e.g., a most recent of the iteratively obtained primary reference UE locations).

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process may include receiving, at a network device (e.g., a user equipment (UE)) from a network entity via a number of sensing streams based on a maximum of Nt-J sensing streams, a waveform including communications resources and sensing resources. The waveform has a rank Nt and J is a number of layers scheduled for multiple-input multiple-output (MIMO) communications that is less than Nt. The process may further include processing at least the communications resources of the waveform.
