Abstract: Techniques are disclosed for determining the location of an object using RF sensing. More specifically, an object may be detected in a wireless data communication network using radar techniques in which one or more base stations act as a transmitter and a mobile device (e.g., a user equipment (UE)) acts as a receiver in a bistatic or multi-static radar configuration. By comparing the time a line-of-sight (LOS) signal is received by the mobile device with that of an echo signal from a reflection of an RF signal from the object, a position of the object can be determined. Depending on desired functionality, this position can be determined by the UE, or by a network entity.

Abstract: Methods, systems, and devices for reducing latency for closed loop sidelink communications for non-terrestrial networks (NTNs) are described. In some examples, a first user equipment (UE) may transmit, to a network entity, a message requesting an allocation of sidelink resources for the first UE and an allocation of sidelink resources for a second UE. The first UE may receive, from the network entity in response to the request message, an indication of a first set of sidelink resources for the first UE. In some examples, the first UE may transmit one or more data messages to the second UE, including an indication of a second set of sidelink resources, an indication that the network entity may directly allocate the second set of sidelink resources, or both. In some example, the first UE may receive one or more data messages from the second UE on the second set of sidelink resources.

Abstract: In an aspect, a communications node (e.g., TRP or UE) obtains (e.g., measures) timing group delays associated with different positioning procedures to determine time drift information, and reports the time drift information to an external entity for position estimation. In some designs, positioning procedures may comprise round trip time (RTT) measurements or uplink or downlink Difference Of Arrival (TDOA) measurements. In some designs, the time drift information indicates a drift rate function.

Abstract: In a positioning session for a user equipment (UE), one or more base stations may receive and derive positioning measurements from uplink (UL) transmission from the UE that include a physical resource block (PRB) interlaced waveform based on at least one of interlaced physical uplink control channel (PUCCH) resource blocks, interlaced physical uplink shared channel (PUSCH) RBs resource blocks, interlaced sounding reference signal (SRS), interlaced uplink (UL) positioning reference signal (PRS), or a combination thereof. The interlaced waveforms span a greater wavelength than if interlacing were not used, and an enhanced accuracy requirement for the positioning measurements based on the span may be used for the positioning measurements. The UL interlaced PRBs may be used for UL positioning measurements for combined downlink (DL) and UL positioning measurements. The base station may report the positioning measurements along with the channel used and enhanced accuracy requirements to a location server for positioning.

Abstract: Radio frequency (RF) sensing of a target object by a wireless network is supported by a sensing node and a network node using sensing assistance data. The sensing assistance data may include information for Doppler estimation from received RF signals. The information for Doppler estimation, for example, may include an indication of phase coherency of RF signals, such as phase coherence found in positioning reference signal (PRS) resources, resource sets, transmission reception points (TRPs), frequency layer or any combination thereof. The sensing assistance data may include an association of PRS resources and reference point objects (RPOs) so RF signals reflected from the RPOs may be excluded from the sensing measurements. The sensing assistance data may include beam pattern information for PRS resources for beam coordination for RF sensing.

Abstract: Aspects described herein relate to receiving, from a network node, a first transmission for configuring a configured grant, wherein the configured grant allocates one or more resources associated with an uplink transmission process having a transmission process identifier, obtaining a first indication that the network node uses a fallback downlink control information (DCI) format, and modifying, based at least in part on obtaining the first indication and the transmission process identifier, the uplink transmission process. Other aspects relate to configuring a device for modifying the uplink transmission process, receiving uplink communications based on the modified uplink transmission process, and/or the like.

Abstract: Methods of reducing the interferences of radar signals with uplink or downlink data communication signals in a wireless system for both data communication and radar sensing may include configuring the transmitters of the radar signals and the data communication signals such that the data communication signals and the radar signals are transmitted using different radio frequency resources, and/or configuring the receivers of the data communication signals to receive the data communication signals using a receive beam that does not collide with radar beams. The methods may also include using a reference signal for both downlink data communication and radar sensing and/or determining a Quasi-Colocation (QCL) configuration for downlink data reception based on information regarding a radar beam.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) measures one or more positioning reference signal (PRS) resources of at least one PRS instance, and processes the one or more PRS resources of the at least one PRS instance during a PRS processing gap, wherein the PRS processing gap comprises a period of time during which the UE prioritizes PRS processing over reception, processing, or both of other downlink signals and channels.
