Abstract: Disclosed are systems and techniques for efficient joint communications and radio frequency (RF) sensing. For example, a method for communications and sensing can include receiving, by a receiver, a first signal based on a reflection of a second signal from a target, wherein the first signal comprises a waveform including a plurality of communications instances and a plurality of sensing instances. The method can include determining, using radio frequency sensing, at least one characteristic of the target based on information in at least one of the plurality of sensing instances.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media to determine a location of a device using carrier phase positioning. A process includes transmitting, at the device to a network entity, a phase measurement capability of a device (e.g., a user equipment (UE)) for subcarrier set pairs of different resources received by the device. The different resources are associated with a reference signal. The process can include receiving, at the device, a phase measurement request from a network entity for configuring phase measurements of the subcarrier set pairs of the different resources. The process can include transmitting a phase measurement report to the network entity based on the phase measurement request, the phase measurement report including information associated with a measured phase difference of at least one subcarrier set pair associated with the different resources.

Abstract: In some implementations, a mobile device may receive a UWB positioning session configuration message from each of one or more UWB anchor devices. The mobile device may determine to perform hybrid NR/UWB positioning of the mobile device and may initiate the hybrid NR/UWB positioning of the mobile device. Initiating the hybrid NR/UWB positioning of the mobile device may comprise: conducting an NR positioning session with a Location Management Function (LMF) of a NR network and conducting a UWB positioning session with each of at least a subset of the one or more UWB anchor devices.

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communication at a user equipment (UE). A process can include receiving, at the UE from a network entity, a phase measurement request from a network entity. The phase measurement request includes properties of one or more pairs of subcarrier sets of at least one reference signal received by the UE. A subcarrier set includes at least one subcarrier. The process can further include transmitting a phase measurement report to the network entity. The phase measurement report includes information associated with a phase measurement performed using at least one subcarrier set pair of the at least one reference signal based on the properties included in the phase measurement request.

Abstract: Aspects presented herein may enhance the security of UWB ranging, thereby improving the accuracy and reliability of the UWB ranging. In one aspect, a first wireless device embeds first information for generating a secure sequence of a ranging message in a payload section of the ranging message. The first wireless device generates the secure sequence based at least in part on the first information. The first wireless device transmits the ranging message including the secure sequence and the payload section for a second wireless device. In another aspect, a second wireless device receives a ranging message from a first wireless device that includes a first secure sequence and a payload section. The second wireless device generates a second secure sequence based on information embedded in the payload section of the ranging message.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a first network node transmits, to a second network node, a first subset of a plurality of portions of a first positioning reference signal (PRS) symbol of a PRS resource during a corresponding first subset of a plurality of portions of a first orthogonal frequency division multiplexing (OFDM) symbol, wherein a number of the plurality of portions of the PRS symbol and a number of the plurality of portions of the OFDM symbol are equal to a comb size of the PRS resource, and refrains from transmitting, to the second network node, a second subset of the plurality of portions of the PRS symbol during a corresponding second subset of the plurality of portions of the first OFDM symbol.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a first physical downlink shared channel (PDSCH) transmission transmitted using a first modulation and coding scheme (MCS). The UE may transmit, to the base station, feedback based at least in part on decoding the first PDSCH transmission, wherein the feedback includes an acknowledgement (ACK) or negative acknowledgement (NACK) and a channel state information (CSI) report that includes at least an indication of a second MCS based at least in part on a target block error rate (BLER) and a target charging rate for energy harvesting. Numerous other aspects are described.

Abstract: A method of wireless communication performed by a user equipment (UE) is disclosed and includes determining a position of the UE based on a first positioning synchronization source; pre-configuring a first sidelink coordination group for use by the UE prior to an occurrence of one or more first triggering events, wherein the first sidelink coordination group uses a second positioning synchronization source that is different than the first positioning synchronization source; and in response to a determination that the one or more first triggering events has occurred, transitioning to use of the first sidelink coordination group for determining the position of the UE.
