Abstract: Techniques are provided for performing channel stitching for cellular based radio frequency (RF) sensing. An example method of determining range information using joint communication and sensing includes receiving assistance data for joint communication and sensing operations, wherein the assistance data includes mixed numerology information indicating at least a first subcarrier spacing and a second subcarrier spacing, performing joint communication and sensing operations utilizing the first subcarrier spacing to receive communication symbols and the second subcarrier spacing to receive radio frequency sensing symbols, performing one or more channel stitching operations based on the received radio frequency sensing symbols, and determining range information based at least in part on the one or more channel stitching operations.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a receiving entity (RE), e.g., a user equipment or base station, receives a positioning resource beam configuration that defines a set of positioning resources, each positioning resource being transmitted by a transmission/reception point (TRP) at different times using different beams, each of the different beams having a set of beam characteristics that differs from the set of beam characteristics of another of the different beams in at least one beam characteristic. The RE performs positioning measurements on the different beams at the different times, at least based on the sets of beam characteristics, and sends positioning information to the TRP, the positioning information comprising at least some of the positioning measurements, a positioning estimate, or combinations thereof.

Abstract: Reference signals used in location estimation of a user equipment (UE) in a wireless data network can be secured against a man-in-the-middle attack by a transmitting device withholding the conveyance of transmission parameters for decoding portions of a reference signal until after the portions are transmitted. Thus, receiving devices can buffer received signals and, after receiving the transmission parameters, process the buffered signals. To further prevent an attacker device from attacking future reference signals, transmission parameters can be nondeterministic such that an attacker device obtaining a parameter at a certain period of time is unable to use the decoded parameter predict or determine subsequent transmission parameters.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a receiving entity receives information that characterizes a set of positioning signals to be transmitted by a transmission/reception point (TRP) using a set of transmission beams, the information comprising at least one antenna element radiation pattern, at least one antenna element array configuration, and, for each beam in the set of transmission beams, information identifying at least one precoding matrix. The receiving entity performs measurements of the positioning signals transmitted by the TRP, and calculates at least one positioning measurement estimate based on at least some of the at least one antenna element radiation pattern, the at least one antenna element array configuration, the information identifying at least one precoding matrix, and the positioning measurements. The receiving entity sends positioning information to the TRP. The positioning information may include the at least one positioning measurement estimate.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) derives a time reversal (TR) precoder based at least in part on an estimated channel between the first UE and a second UE, and sends, to the second UE, a TR-precoded sidelink (SL) positioning reference signal (PRS). The estimated channel may be based on channel state information (CSI) associated with a wideband (WB) reference signal (RS). The TR precoder may be based on transmissions or receptions on a SL communication channel between the first UE and the second UE.

Abstract: A method of assessing a reported UE location includes: receiving, at a network entity, the reported UE location; obtaining, at the network entity, a first signal frequency difference indicating a first difference between a received frequency of a first signal received by the UE corresponding to a first transmit signal of a first transmit frequency transmitted from a first non-terrestrial-network node, and a received frequency of a second signal received by the UE corresponding to a second transmit signal of a second transmit frequency transmitted from a second non-terrestrial-network node that is separate from the first non-terrestrial-network node; and providing, by the network entity, a UE location assessment indication based on the first signal frequency difference and a second difference between an expected frequency of the first signal at the reported UE location and an expected frequency of the second signal at the reported UE location.

Abstract: Radio frequency (RF) sensing by a sensing entity with an oscillator that introduces frequency errors is supported using dual direction bistatic sensing. The sensing entity transmits a sensing signal that is reflected by an object and received by a second sensing entity, which measures a first frequency offset that includes an oscillator error from the transmission of the sensing signal and a Doppler shift from the object. The sensing entity also receives and measures a second frequency offset of a sensing signal transmitted by the second sensing entity and reflected by the object, which includes a second frequency offset that includes an oscillator error from the reception of the sensing signal and a Doppler shift from the target object. The velocity of the object may be estimated based on a combination of the first and second frequency offsets, which cancels the oscillator error caused by the sensing entity.

Abstract: Techniques for enabling a cross-link interference (CLI) based uplink (UL) angle-of-arrival (AoA) estimations are disclosed. A victim user equipment (UE) may be configured with CLI resources to measure CLIs from one or more aggressor UEs. The victim UE may take the CLI opportunities also to estimate the AoAs of the UL signals from the aggressor UEs. In this way, UE's location estimation may be enhanced.

Abstract: A user equipment (UE) transmits a first message spanning a set of physical resource blocks (PRBs). The UE retransmits a first portion of the first message associated with a first subset of one or more PRBs in the set of PRBs, the set of PRBs grouped into a set of PRB bundles including a first subset of PRB bundles corresponding to the first subset of the one or more PRBs and skips retransmission of a second portion of the first message associated with a second subset of the PRB bundles of the set of PRB bundles, the second subset of the PRB bundles corresponding to at least a portion of remaining PRBs in the set of PRBs.

Abstract: Systems and techniques for wireless communications are provided, including resource allocation for joint communications and RF sensing of objects. For example, a radar receiver (or component thereof) may determine a sensing measurement accuracy of the radar receiver based on one or more measurements associated with at least one target. The radar receiver (or component thereof) may transmit, based on the sensing measurement accuracy, a message to a network entity. The message may include an indication to modify an allocation of sensing resources associated with the radar receiver for communications data. The network entity (or component thereof) may receive the message from the radar receiver and may determine at least a portion of the sensing resources for the communications data. The radar receiver (or component thereof) may receive, from the network entity, resource allocation signaling for the communications data based on the indication to modify the allocation of sensing resources.
