Abstract: Methods, systems, and devices for wireless communications are described. A base station (e.g., next-generation NodeB ((gNB)) may transmit a report configuration to a user equipment (UE). The report configuration may include a first set of quasi co-location parameters for channel measurement and a second set of quasi co-location parameters for interference measurement. At least one quasi co-location reference associated with a first quasi co-location parameter of the first set may be different than a quasi co-location reference associated with a second quasi co-location parameter of the second set. The quasi co-location references may include different quasi co-location Typed references that correspond to different spatial receive beams. The UE may perform the channel measurement based on a first resource setting for the channel measurement and the first set of quasi co-location parameters. The UE may perform the interference measurement based on a second resource setting for the interference measurement and the second set of quasi co-location parameters.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may transmit, to a network entity comprising a location server and/or base station, a positioning capability report that includes a set of positioning capability parameters for a radio resource control (RRC) connected state. The UE may enter an RRC unconnected state, the RRC unconnected state comprising an RRC inactive state or an RRC idle state. The UE may perform positioning reference signal (PRS) processing during the RRC unconnected state according to one or more positioning capability parameters from the set of positioning capability parameters for the RRC connected state.

Abstract: Various aspects of the disclosure relate to techniques associated with the acquisition of reference signals. In some aspects, a network may request a user equipment (UE) to measure a timing difference between neighbor cells and use that information to generate a CSI-RS configuration. The network sends the CSI-RS configuration to the UE to enable the UE to acquire a CSI-RS from a neighbor cell. In some aspects, a network may send timing-related information to a neighbor cell and the neighbor cell uses that information to transmit a CSI-RS.

Abstract: Disclosed are various techniques for wireless communication. In an aspect, a user equipment (UE) may determine a plurality of measurement gap (MG) configurations, each MG configuration defining one or more MGs. The UE may send, to a serving base station, a request to use a first MG configuration from the plurality of MG configurations, and may receive a response to the first request. The UE then measures positioning signals using an MG configuration indicated by the response. Based on measurements of the first set of positioning signals, the UE may select a second MG configuration, send a second request to use the second MG configuration, and receive a response to the second request. The UE then measures a second set of positioning signals using an MG configuration indicated by the response to the second request.

Abstract: In an aspect, a first BS measures a SRS-P associated with a RTT measurement procedure between a UE and a second base station, and reports measurement information based on the measurement of the SRS-P. In another aspect, a device (e.g., UE, BS, LMF, etc.) obtains the measurement information along with measurement information based on measurements at the UE and the second base station, and determines a positioning estimate of the UE based on the first, second and third measurement information.

Abstract: In an aspect, a communications device (e.g., UE, BS, LMF component, etc.) determines information related to a first positioning reference signal (PRS) configuration (e.g., UL-PRS configuration such as SRS-P, or DL-PRS configuration) associated with a user equipment (UE), determines information related to a first discontinuous reception (DRX) configuration associated with the UE, determines that a first PRS operation requirement of the first PRS configuration is not satisfied by the first DRX configuration due to a DRX limitation condition, and perform an action in response to the determination that the first PRS operation requirement of the first PRS configuration is not satisfied by the first DRX configuration due to the DRX limitation condition.

Abstract: In an aspect, a BS transmits PRS on a first frequency-domain resource during a measurement period. A UE measures the PRS, and transmits a RS-P (e.g., SRS-P) on a second frequency-domain resource that does not overlap with the first frequency-domain resource in frequency.

Abstract: A method of facilitating position determination of a user equipment includes: receiving, at the user equipment, a first plurality of positioning reference signal portions having a corresponding plurality of frequency sub-bands; processing, at the user equipment, one or more of the first plurality of positioning reference signal portions to determine position information; and at least one of: transmitting a capability message, to a network entity, indicating a processing capability of the user equipment to process, in combination, positioning reference signal portions having different frequency sub-bands to determine the position information; or transmitting a signal-combination indication, to the network entity, indicating a second plurality of positioning reference signal portions, of the first plurality of positioning reference signal portions, processed by the user equipment in combination to determine the position information.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a network entity determines a location of a target base station and a location of at least one reference device, determines an angle-of-arrival (AoA) measurement of one or more reference signals received by at least one antenna array of the target base station from the at least one reference device, determines an expected AoA between the at least one antenna array and the at least one reference device based on the location of the target base station and the location of the at least one reference device, and determines an orientation offset of the at least one antenna array based on a difference between the expected AoA and the AoA measurement.

Abstract: Techniques are provide for calibrating device timelines for use in passive positioning of user equipment (UE). An example method for passive positioning of a user equipment includes receiving a first positioning reference signal from a first device at a first time, receiving a second positioning reference signal from a second device at a second time, receiving a timeline difference value associated with the first device and the second device, and determining a time difference of arrival between the first positioning reference signal and the second positioning reference signal based at least in part on the timeline difference value.
