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: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) measures one or more positioning reference signal (PRS) resources of at least one PRS instance, and processes the one or more PRS resources of the at least one PRS instance during a PRS processing gap, wherein the PRS processing gap comprises a period of time during which the UE prioritizes PRS processing over reception, processing, or both of other downlink signals and channels.

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.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may obtain updated location information, and determine a time difference between a previous communication with a network and a scheduled uplink transmission. Based on the determined time difference, the UE may determine a timing advance (TA) component of a TA value to apply for the uplink transmission, and transmit an uplink message in the uplink transmission according to the determined TA value and the location information. In some examples, the time difference may be based on a first duration between the uplink transmission and a previous uplink transmission, a second duration between the uplink transmission and a previous TA command received from the network, or both. In some examples, the determined TA value may be based on additional parameters, such as an autonomous adjustment step, an aggregate adjustment rate, a scaling factor, or any combination thereof.

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: Wireless positioning accuracy of a user equipment (UE) is impacted by locations of the transmit/receive points (TRPs) and UE for wireless positioning. To improve the accuracy of estimated locations, a geometric dilution of precision (GDOP) may be determined for different groups of candidate TRPs, with the GDOP indicating a potential positioning error associated with the group of candidate TRPs. A UE may determine GDOPs for different combinations of candidate TRPs. One or more devices of a wireless network (e.g., a location server and/or a UE for positioning) may select or exclude one or more candidate TRPs from being used for wireless positioning of a UE based on the determined GDOPs. Exclusion or selection of candidate TRPs for wireless positioning may also be based on quality measurements of PRSs (such as an RSRP or SNR) or a time duration associated with measuring the PRSs from the candidate TRPs to be selected.
