Abstract: During positioning of a user equipment (UE), (DL) positioning reference signals (PRS) transmitted by one or more transmission reception point (TRP) in a wireless communication system may be preempted or punctured by higher priority transmissions, such as ultra-reliable low-latency traffic (URLLC). A PRS preemption indication (PI) may be provided to a UE identifying one or more TRPs affected by preemption. The PRS PI may further identify the time domain and frequency domain of the preempted DL PRS transmissions. The PRS PI may identify the time domain, e.g., based on a number of PRS symbols between two monitoring occasions, wherein only PRS symbols that contain positioning reference signals associated with the group of TRPs are counted. The PRS PI may identify the frequency domain by identifying at least one of four or more frequency sub-bands of the preempted DL PRS transmissions.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to estimate a signal-to-noise ratio for each antenna port associated with a reception of one or more tracking reference signals. The UE may receive one or more of multiple single-port tracking reference signals, a single multi-port tracking reference signal, or a tracking reference signal associated with multiple power ratios. The UE may be able to estimate a channel upon receiving a demodulation reference signal. The channel estimation may be based on the reception of one or more of multiple single-port tracking reference signals, the single multi-port tracking reference signal, or the tracking reference signal associated with multiple power ratios. The UE may communicate with the base station based on estimating the channel.

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: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives, from one or more transmission-reception points (TRPs), one or more on-demand downlink positioning reference signals (DL-PRS), the one or more on-demand DL-PRS having one or more downlink transmission parameters, and transmits, to the one or more TRPs, one or more uplink positioning reference signals (UL-PRS), the one or more UL-PRS having one or more uplink transmission parameters, wherein values of the one or more uplink transmission parameters are the same as or within a threshold of values of the one or more downlink transmission parameters.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive downlink control information (DCI) that includes an indication of a null resource element pattern. The null resource element pattern may be indicated in the DCI using: a value of an antenna port field that also indicates one or more demodulation reference signal (DMRS) ports for the UE and a number of DMRS code-division multiplexing groups without data, or one or more zero power downlink reference signals. The UE may perform one or more demodulation interference measurements based at least in part on the null resource element pattern. The UE may demodulate a downlink communication based at least in part on performing the one or more demodulation interference measurements. Numerous other aspects are provided.

Abstract: In an aspect, a network component (e.g., BS, LMF, etc.) determines a capability of the UE perform receive frequency hopping to measure a downlink positioning reference signal (DL-PRS) across a plurality of frequency hops, the DL-PRS transmitted over a plurality of orthogonal frequency division multiplex (OFDM) symbols on a same transmission bandwidth (e.g., without frequency hopping), and each of the plurality of frequency hops associated with a sub-band of the transmission bandwidth of the DL-PRS, and configures one or more parameters associated with positioning of the UE based at least in part on the capability. In some designs, the UE may send an indication of the capability to the network component to facilitate the determination, while in other designs the network component may determine the capability via another mechanism.
