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: 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.
