Abstract: Techniques are disclosed for determining an object's location by using a Reconfigurable Intelligent Surface (RIS) to aid in RF sensing. Radar techniques can be used in which one or more base stations act as a transmitter and a receiving device acts as a receiver in a bistatic or multi-static radar configuration where an RIS directs signals transmitted by the one or more base stations to the receiving device. By comparing the time a line-of-sight (LOS) signal (redirected to the receiving device by the RIS) is received by the receiving device with that of an echo signal (redirected to the receiving device by the RIS) from a reflection of an RF signal from the object, a position of the object can be determined. Depending on desired functionality, this position can be determined by the receiving device or by a location server or other network entity.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a base station (BS) transmits, to a user equipment (UE), a first configuration of a first radio access network notification area (RNA) associated with paging of the UE while the UE is in an radio resource control (RRC) INACTIVE state, the first RNA comprising a first set of cells. In a further aspect, the BS transmits, to the UE, a second configuration of a second RNA associated with positioning of the UE while the UE is in the RRC INACTIVE state, the second RNA comprising a subset of the first set of cells.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for a device such as a user equipment (UE), a base station, or both, to perform a channel noise and interference estimation based on a set of null resources in a data channel. The device may identify a first configuration for a set of demodulation reference signals (DMRSs) in a first set of time periods of a data channel and a second configuration for a set of null resources in a second set of time periods of the data channel. The second set of time periods may be nonoverlapping with the first set of time periods. The device may perform a channel estimation procedure on the data channel based on the null resources and the DMRS resources. The device may process data received via resources of the data channel based on the channel estimation procedure.

Abstract: A signal processing method includes: receiving, at a UE, a PRS and a supplemental signal, the supplemental signal being a broadcast signal and spanning a first frequency range at least partially outside of a second frequency range spanned by the PRS; processing, at the UE, the PRS and the supplemental signal in combination, resulting in an effective signal bandwidth that is larger than the second frequency range, to determine position information; and at least one of: transmitting a capability message, from the UE to a network entity, indicating a processing capability of the UE to process, in combination, the PRS and the supplemental signal; or transmitting a signal-combination indication, from the UE to the network entity, indicating that the UE processed the PRS and the supplemental signal in combination to determine the position information.

Abstract: Disclosed are various techniques for wireless positioning. In an aspect, a user equipment (UE) determines one or more angle-based measurements of one or more reference signal resources transmitted by or received at the UE on one or more antennas of the UE and reports, to a positioning entity, the one or more angle-based measurements, a beam pattern associated with the one or more reference signal resources, a type of the one or more antennas, locations of the one or more antennas on the UE, an orientation of the one or more antennas, or any combination thereof.

Abstract: A UE includes: an interface comprising at least one of a receiver and a transmitter; a memory; and a processor, communicatively coupled to the interface and the memory, configured to: identify a processing conflict for an exchange of a first UE-to-UE location reference signal and an exchange of a first radio-network-interface signal; determine a priority of the exchange of the first UE-to-UE location reference signal and the exchange of the first radio-network-interface signal; and exchange, via the interface, one of the first UE-to-UE location reference signal or the first radio-network-interface signal according to the priority.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit, to a base station, a UE capability message indicating support for at least a first demodulation mode or a second demodulation mode. The first demodulation mode may correspond to a single demodulation procedure associated with a set of antenna ports at the UE, and the second demodulation mode may correspond to multiple demodulation procedures, each procedure associated with a respective subset of antenna ports at the UE. In some cases, the UE may flexibly switch between demodulation modes. The UE may receive, from the base station, one or more downlink signals via one or more downlink beams based on the indication of the first demodulation mode or the second demodulation mode. The UE may demodulate the one or more downlink signals based on the indicated (e.g., an active) demodulation mode.

Abstract: Aspects relate to sounding on a subset of available sounding resources. A user equipment (UE) may transmit a sounding reference signal (SRS) on a subset of the frequency resources available for a hop of an SRS hopping sequence. A UE may be configured to use a subset of frequency resources or the UE may autonomously identify this subset. A base station may send a bit map to a UE to indicate the subset of resources to use for a hop. Each bit of the bit map may indicate that the UE is to transmit an SRS on a particular RB or on a particular groups of RBs. The same subset of resources may be designated for each hop or different subsets of resources may be designated for different hops. An indication of the subset of resources may be provided for each hop. The subset of resources may be cycled for different hops.

Abstract: Aspects relate to wireless communication for slot postponing of aperiodic sound reference signals (A-SRS) by a user equipment in a wireless network. A network node, such as a gNodeB, may send at least a portion of a slot postponing configuration for transmission of aperiodic sounding reference signals (A-SRSs) to a user equipment (UE). In a particular aspect, the slot postponing configuration is established through RRC signaling and does not utilize downlink control information (DCI) or MAC-CE sent parameters for establishing the slot postponing configuration. The slot positioning configuration is used to control slot offset postponing, the number of slot offsets, the number of times transmission of A-SRS can be postponed in the UE, and priority rules based on the postponing configuration.

Abstract: In an aspect, a network entity transmits, to a UE, a PRS configuration that configures a plurality of PRS measurement occasions (MOs)) of one or more PRS resources associated with a transmission reception point (TRP), wherein each PRS MO is transmitted on a different time instance on the same bandwidth. The UE performs one or more measurements at each of the plurality of PRS MOs of the same PRS resource of the one or more PRS resources. The UE transmits, to the network entity, a single measurement report comprising measurement information associated with the one or more measurements derived on the same PRS resource from two or more of the plurality of PRS MOs.
