Abstract: Techniques are disclosed for using reference signals that enable accurate measurements of a moving UE. To this end, techniques can include a location server obtaining an indication that the velocity of the UE exceeds a threshold and, in response, configuring the UE to measure a reference signal using a selected Tracking Reference Signal (TRS) as a Quasi-Collocation (QCL) reference. In particular, a periodic TRS (P-TRS) or an aperiodic TRS (AP-TRS) can be used as the QCL reference. A reference signal may be configured based on an existing TRS configuration, or a TRS may be configured based on a reference signal configuration. According to some embodiments, a UE may provide velocity information to the location server. Additionally or alternatively, a measurement period for the reference signal may be based on a velocity of the UE.

Abstract: Disclosed are techniques for positioning. In an aspect, a network node receives, from a network entity, one or more parameters for a neural network, performs one or more measurements of at least one reference signal from a target user equipment (UE) based on a measurement configuration for the at least one reference signal, generates one or more statistics of one or more features of the at least one reference signal based on the neural network and the one or more measurements, and reports the one or more statistics to the network entity to enable the network entity to estimate a location of the target UE based on the one or more statistics and a location of the network node.

Abstract: A method of providing positioning state information in a channel usable for conveying the positioning state information includes: obtaining a positioning state information resource allocation parameter; determining a positioning resource amount based on the positioning state information resource allocation parameter, the positioning resource amount being an amount of resources of the channel usable for conveying the positioning state information; and transmitting the positioning state information over the channel while occupying no more than the positioning resource amount of resources of the channel.

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: Disclosed are techniques for wireless positioning. In an aspect, a first network node. In an aspect, the first network node receives assistance data for a plurality of positioning reference signal (PRS) resources transmitted by a second network node, the assistance data including one or more transmit timing error group (Tx TEG) identifiers, each Tx TEG identifier of the one or more Tx TEG identifiers associated with one subset of one or more subsets of the plurality of PRS resources, and performs one or more positioning measurements of at least one subset of the one or more subsets of the plurality of PRS resources based on the one or more Tx TEG identifiers.

Abstract: Disclosed are techniques related to wireless communications. In an aspect, a network entity determines whether a source reference signal transmitted from a first transmission-reception point (TRP) is a quasi-collocation (QCL) source of a target reference signal transmitted from a second TRP based, at least in part, on a first bandwidth (BW) portion occupied by the source reference signal and a second BW portion occupied by the target reference signal, the first BW portion having a first start frequency and a first BW size and the second BW portion having a second start frequency and a second BW size, and configures a user equipment (UE) with the source reference signal as the QCL source of the target reference signal when it is so determined.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a message indicating that a symbol for a repetition of a sounding reference signal (SRS) resource in a first slot is canceled or blocked. The UE may drop transmission of one or more other symbols for the SRS resource in the first slot based at least in part on the message. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for randomization of reconfigurable intelligent surface (RIS) signals. A method for wireless communication includes determining a random reflection parameter for each of one or more RISs. The random reflection parameter is random over time for the one or more RISs. The method includes applying random values of the random reflection parameter at different times at each of the one or more RISs.

Abstract: A UE receives, from a BS, information indicating a first TEG delay at the BS for a transmission of a first PRS, a second TEG delay at the BS for a reception of an SRS from the UE, a third TEG delay at the BS for a transmission of a second PRS, a fourth TEG delay at the BS for a transmission of the first PRS and a reception of the SRS from the UE, or a fifth TEG delay at the BS for a reception of the SRS from the UE and a transmission of the second PRS, or any combination thereof. The UE determines a double RTT based on a first PRS timing associated with a reception of the first PRS, an SRS timing associated with a transmission of the SRS, a second PRS timing associated with a reception of the second PRS, and the received information.
