Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may receive, from a network entity, a cross-link interference (CLI) sounding reference signal (SRS) measurement resource configuration that indicates an orthogonal time frequency space (OTFS) modulated SRS associated with a second UE. The first UE may receive, from the second UE, the OTFS modulated SRS based at least in part on the CLI SRS measurement resource configuration. The first UE may perform a CLI measurement over one or more symbols in which the OTFS modulated SRS is transmitted. The first CE may transmit, to the network entity, a measurement report that indicates the CLI measurement. Numerous other aspects are described.

Abstract: A mono-static radio frequency sensing coordination method includes: determining, by a network entity for a first apparatus that is a first radio frequency sensing apparatus, a first configuration of a first cellular network signal for mono-static radio frequency sensing such that the first cellular network signal has expected interference of less than a threshold interference due to transmission of a second cellular network signal from a second apparatus that is separate from the first apparatus; and transmitting, from the network entity to the first apparatus, a first configuration message indicating for the first apparatus to use the first configuration of the first cellular network signal for monostatic radio frequency sensing.

Abstract: Aspects of the disclosure involve multiplexing the transmission of communications signals and sensing signals at the resource element level. A frequency modulated continuous wave (FMCW) signal and plurality of orthogonal frequency-division multiplexing (OFDM) signals may be transmitted within an air interface frame structure having a plurality of resource elements, each resource element defined over a symbol duration in a time domain and a subcarrier in a frequency domain. The FMCW signal occupies a first plurality of resource elements and comprises a FMCW waveform repeated in the time domain and transmitted during a first symbol, over a first plurality of subcarriers of the air interface frame structure. The plurality of OFDM signals occupy a second plurality of resource elements in the air interface frame structure and are transmitted during the first symbol, over a second plurality of subcarriers of the air interface frame structure.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a network entity, such as a location server or base station, may determine a positioning reference signal (PRS) frequency hopping configuration that specifies a plurality of PRS hops within a PRS resource set, each PRS hop occupying a specified set of one or more contiguous physical resource blocks, and further specifying a time gap between PRS hops to allow a sufficient retuning gap for a user equipment (UE) with reduced BW capability and/or relaxed processing time. The network entity may transmit the PRS frequency hopping configuration to at least one UE, e.g., via broadcast, multicast, groupcast, or unicast over Uu or PC5 links. The pre-configured time gap between PRS hops allows a reduced capacity UE to retune its RF circuit and thus allow PRS measurements over a larger bandwidth than what the UE can support without frequency hopping.

Abstract: Disclosed are techniques for wireless communication. In an aspect, timing of a PRS instance is determined, and timing of a PO is determined based at least in part upon the timing of the PRS instance. UE transitions from DRX OFF state to DRX ON state and receives/measures the PO and PRS resource(s) of the PRS instance (e.g., without returning to DRX OFF state or sleep state until both the PO and PRS resource(s) are received/measured).

Abstract: Disclosed are systems, apparatuses, processes, and computer-readable media for wireless communications. For example, an example of a process may include a RIS that can receive, from a satellite, a positioning reference signal. The RIS can further reflect the positioning reference signal to produce a reflection positioning reference signal radiated towards a network device for positioning of the network device.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may receive a first indication to perform a first positioning measurement having a first measurement method type and targeting a first positioning frequency layer (PFL). The UE may receive, prior to completion of measurements associated with the first positioning measurement, a second indication to perform a second positioning measurement having a second measurement method type and targeting a second PFL. The UE may determine an order in which to perform the measurements associated with the first indication and measurements associated with the second indication. The UE may perform the measurements associated with the first indication and the measurements associated with the second indication according to the order.
