Abstract: Systems and techniques are provided for wireless communications performed at a network entity. For example, the systems and techniques can include obtaining, at the network entity, a target relative time difference (RTD). A transmission timing pre-compensation can be determined at the network entity between a first reference signal and a second reference signal, wherein the transmission timing pre-compensation is determined based on the target RTD and one or more network delay components. The first reference signal and the second reference signal can be transmitted using the transmission timing pre-compensation to offset the first reference signal from the second reference signal by the target RTD.

Abstract: Aspects presented may enable RF sensing to be adaptive to the environment to improve the sensing, performance, and/or the spectrum efficiency of cellular systems and the power efficiency of RF sensing nodes. In one aspect, an RF sensing node extracts one or more features for a set of objects of an area via at least one non-RF sensor. The RF sensing node transmits, to a network entity, the one or more features or at least one non-RF measurement derived from the one or more features. The RF sensing node receives, from the network entity, an RRS transmission configuration derived based on the one or more features or the at least one non-RF measurement transmitted to the network entity.

Abstract: Disclosed are techniques for reducing the overhead of low layer positioning reports. In an aspect, a user equipment (UE) performs at least one positioning measurement of at least one downlink positioning reference signal (DL-PRS) received from at least one transmission-reception point (TRP) during a positioning session, and reports, to a positioning entity via low layer signaling, a relative value of the at least one positioning measurement relative to an expected value of the at least one positioning measurement, wherein the relative value of the at least one positioning measurement is a difference between the expected value of the at least one positioning measurement and a measured value of the at least one positioning measurement.

Abstract: Sounding reference signals (SRS) transmitted by a UE, e.g., for positioning or channel estimation, may be configured for one or both of frequency tone level cyclic shift and symbol level code, which, for example, enables multiplexing a greater number of UEs. The frequency tone level cyclic shift is produced by jointly processing a number of symbols with an extended cyclic shift structure. The SRS may be configured using a symbol group level that indicates the number of symbols associated with a cyclic shift structure, and an outer code that indicates a multiplier applied to the SRS at the symbol level, which increases the multiplexing opportunities. The symbol level code may further indicate an extended cyclic shift indicating a linear increase in phase rotation across tones in symbols associated with the symbol group level.

Abstract: During positioning of a user equipment (UE), downlink (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 by a serving TRP 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 downlink 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: 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.

Abstract: Techniques and devices for wireless communications are described. A user equipment (UE) may receive a configuration from a network entity for multiplexing a reference signal with a data signal in time and in frequency or for multiplexing the reference signal in a Doppler domain. The UE may receive an assignment of multiple time-frequency resources from the network entity for transmission of the reference signal. The UE may multiplex the reference signal across the assigned time-frequency resources in accordance with the received configuration. The UE may transmit the multiplexed reference signal to the network entity.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) reports, to a network entity, a minimum number of symbols of a positioning reference signal (PRS) resource of a first transmission-reception point (TRP) of a pair of TRPs based on a reference signal time difference (RSTD) uncertainty parameter for the pair of TRPs, wherein the minimum number of symbols is less than a total number of symbols allocated for the PRS resource, and performs a positioning measurement of the minimum number of symbols of the PRS resource.

Abstract: Disclosed are techniques for communication. In an aspect, a UE reports a combination pattern for a combined measurement associated with samples across PRS occasions of a PRS measurement procedure. In another aspect, a UE reports a combined calibration error of a combined measurement associated with samples across PRS occasions of a PRS measurement procedure. The reported combination pattern and/or combined calibration error may be used by a position estimation entity for derivation of a position estimate of the UE.
