Abstract: Disclosed are systems and techniques for wireless communications. For example, a network device can transmit a sensing signal for sensing one or more targets. The transmitted sensing signal and at least one sensing signal transmitted by at least one other network device of the plurality of network devices includes one or more phase codes and a same frequency modulated carrier wave (FMCW). Each phase code of each sensing signal corresponds to one or more Doppler spectrum patterns. The network device can receive at least one echo signal from the one or more targets. The network device can mitigate Doppler ambiguity in a Doppler spectrum from the at least one echo signal based on the one or more Doppler spectrum patterns.

Abstract: Techniques for channel state feedback using sensing reference signals are disclosed. The techniques can include identifying a channel state information (CSI) report configuration based on CSI reporting configuration information received from a radio access network (RAN) node of a RAN, based on the CSI report configuration, identifying a set of basis reference signals to be measured on a wireless channel of the RAN, wherein the set of basis reference signals includes one or more sensing reference signals, measuring the set of basis reference signals to obtain channel state measurements, determining channel state information based on the channel state measurements, and transmitting a CSI report including the channel state information to the RAN node.

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: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, a network device can configure a synchronization signal block (SSB) based on parameters. The SSB includes a primary synchronization signal (PSS), one or more secondary synchronization signals (SSSs), and one or more physical broadcast channels (PBCHs). The network device can transmit the SSB in one or more signals for at least one of sensing or communications purposes.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a location server may send, and a base station may receive, a request for positioning information. The base station may send, and the location server may receive, sounding reference signal (SRS) configuration information comprising first information that describes a frame structure used by the base station and second information that identifies, based on the frame structure used by the base station, an available slot with respect to a reference for an aperiodic SRS transmission, wherein an available slot comprises a slot that has enough uplink symbols, flexible symbols, or both, in the time domain for all SRS resources of the aperiodic SRS transmission.

Abstract: In some implementations, a device may obtain first set and second sets of pseudoranges for each of a user equipment (UE) and a reference station, corresponding to first second times, wherein the UE is within a threshold distance of a reference station at the first and second times. Each of the first and second sets of pseudoranges comprise a pseudorange from each of first and second low-earth orbit (LEO) satellites at respective first and second times. The second time is at least a threshold duration after the first time. The device may determine a UE location estimate based at least in part on: the first and second set of pseudoranges, and for each of the first and second times, a respective location of (i) each of the first and second LEO satellites, and (ii) the reference station. The device may output an indication of the location estimate.

Abstract: A sensing node may receive a set of sensing signals. The sensing node may calculate a first joint spectrum based on a first windowing function and the set of sensing signals. The sensing node may calculate a second joint spectrum based on a second windowing function and the set of sensing signals, wherein the first windowing function is different than the second windowing function. The sensing node may transmit a first joint spectrum report based on the first joint spectrum and a second joint spectrum report based on the second joint spectrum to a sensing entity. The sensing node may estimate a parameter of a target object based on an optimal spectrum ID received from the sensing entity, where the optimal spectrum ID may be associated with at least one of the first joint spectrum or the second joint spectrum.
