Abstract: Methods and apparatus for allocating resources for radio frequency (RF) reference signals with communications signals are presented. In some embodiments, a transmission reception point (TRP) may transmit (a) a wireless synchronization signal or (b) wireless physical channel data, wherein the wireless synchronization signal comprises a periodically transmitted broadcast signal, and wherein the wireless physical channel data comprises a unicast signal directed to a user equipment (UE); and transmit a radar reference signal multiplexed with the wireless synchronization signal or the wireless physical channel data, wherein the radar reference signal is configured to, when correlated with a reflected version of the radar reference signal, serve as a basis for one or more radar measurements.

Abstract: Disclosed are techniques for wireless environment sensing. In an aspect, a network node transmits, to a network entity, a capability message including one or more capability parameters indicating one or more capabilities of the network node to participate in bistatic or multistatic multiple-input multiple-output (MIMO) radar sensing operations, receives, from the network entity, a configuration message including one or more configuration parameters configuring the network node to participate in a bistatic or multistatic MIMO radar sensing operation, and performs the bistatic or multistatic MIMO radar sensing operation based on the one or more configuration parameters.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, a network entity for wireless communications can transmit wide sensing signal beams in different directions to detect a target. The network entity can detect the target with one or more of the wide sensing signal beams. The network entity can transmit a narrow sensing signal beam in a direction towards the target to track the target, after the target has been detected. The network entity can further increase a power of the narrow sensing signal beam to provide energy to the target.

Abstract: Apparatuses and methods for scrambling of FMCW for interference mitigation in JCS are described. An apparatus is configured to obtain a set of phase-coded FMCW signals that is phase-coded based on a scrambling ID for the first node and/or a second node. The apparatus is configured to descramble the set of phase-coded FMCW signals based on the scrambling ID. The set of phase-coded FMCW signals is descrambled to obtain a set of descrambled FMCW signals. The apparatus is configured to perform sensing, communication, and/or JCS functions based on the set of descrambled FMCW signals. Another apparatus is configured to configure a set of FMCW signals, and to scramble the set of FMCW signals based on a scrambling ID for the first node and/or a second node to obtain a set of phase-coded FMCW signals. The apparatus is configured to transmit, for the second node, the set of phase-coded FMCW signals.

Abstract: Aspects presented herein may enable a network entity (e.g., a location server, an LMF, etc.) to generate and configure virtual anchors and/or virtual positioning reference units (VPRUs) for a UE for UE-based positioning. In one aspect, a network entity receives an indication to perform UE-based positioning for a UE. The network entity configures, for the UE, assistance data that includes a list of virtual anchors and a list of VPRUs for the UE-based positioning. The network entity transmits the assistance data including the list of virtual anchors and the list of VPRUs. The network entity may generate the list of virtual anchors based on a location offset to each physical anchor in a set of physical anchors. The network entity may generate the list of VPRUs based on at least one physical PRU.

Abstract: In an aspect, a target UE determines a capability of the target UE associated with reflections of reference signals for positioning (RS-Ps) off one or more reconfigurable intelligent surfaces (RISs), and transmits an indication of the determined UE capability. A position estimation entity (e.g., LMF) receives the indication, and configures a positioning session for the target UE based at least in part upon the indication.

Abstract: Apparatuses and methods for waveform adaptations in RF sensing are described. An apparatus is configured to operate in one of a wireless communications mode or a sensing mode. The wireless communications mode is associated with at least one of a communications or sensing waveform. The sensing mode is associated with at least one of the communications or the sensing waveform, and the sensing and communication waveforms are different. The apparatus is also configured to obtain an indication of a switch to operate in another of the wireless communications or sensing mode. The apparatus is further configured to switch to the other mode per the indication. Another apparatus is configured to operate in the wireless communications or the sensing mode, to provide an indication of a mode switch, and to switch to the other mode per the indication.

Abstract: In an aspect, a radar controller determines a radar slot format that configures transmission of a reference radar signal on a first symbol over a first link from a first base station to a second base station followed by at least one target radar signal on at least one second symbol over at least one second link from the first base station to the second base station, and transmits an indication of the radar slot format to the first base station and the second base station. The first base station transmits, and the second base station receives, the reference radar signal and the at least one target radar signal in accordance with the radar slot format.
