Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, via one or more component carriers, one or more downlink reference signals from one or more serving or neighboring transmission-reception points (TRPs), wherein a number of the received one or more downlink reference signals is less than or equal to a maximum number of downlink path loss estimates, spatial transmit beam determinations, spatial receive beam determinations, or any combination thereof to be simultaneously maintained by the UE for positioning purposes, and wherein the maximum number does not include any downlink reference signals the UE is already monitoring for other purposes, and performs a downlink path loss estimate, a spatial transmit beam determination, a spatial receive beam determination, or any combination thereof at least based on each of the received one or more downlink reference signals.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) operating in discontinuous reception (DRX) mode receives a DRX configuration, receives a reference signal resource configuration, determines, at least based on the DRX configuration and the reference signal resource configuration, whether an overlap exists between a reference signal occasion of a plurality of reference signal occasions of the reference signal resource configuration and an active time of the DRX configuration, receives or transmits at least based on a determined overlap, at least a first reference signal in the reference signal occasion, and receives or transmits, while remaining in an active state of the DRX configuration, at least based on the determined overlap, at least a second reference signal in remaining reference signal occasions of the plurality of reference signal occasions after expiration of the active time.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for wireless communication. In one or more aspects, a user equipment (UE) is configured to transmit capability information of the UE for channel state information (CSI) reporting. The UE is further configured to receive, from a base station, configuration information for the CSI reporting. The configuration information indicates a CSI reference resource including a plurality of a first type of time units for CSI reference signal (CSI RS) monitoring, a CSI target resource including one or more of a second type of time units for which channel state information is to be estimated, or both. The CSI target resource is later in time as compared to the CSI reference resource. Other aspects and features are also claimed and described.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) sends, to a network entity, a report indicating positioning capabilities of the UE, the positioning capabilities indicating a number of positioning calculations that the UE can perform per unit of time, per unit of frequency, or both, and performs a first set of positioning-related measurements of a set of positioning reference signal (PRS) resources and reports a second set of positioning-related measurements based on the reported positioning capabilities of the UE, the set of PRS resources to be used for the first and second sets of positioning-related measurements, a set of reporting parameters, an accuracy configuration, a latency configuration, or any combination thereof.

Abstract: Systems and methods for determining round trip time (RTT) includes a second node, which receives a first signal from a first node at a first time, determines a timing advance based on a first estimated channel response for the first signal, and transmits at a second time, a second signal to the first node, wherein the second time occurs after the first time by an amount of a pre-specified delay for RTT estimation minus the timing advance. The first node transmits the first signal to the second node at an initial time, receives the second signal from the second node, and determines a timing statistic from a second estimated channel response for the second signal, the timing statistic estimated at a third time. The first node determines the RTT as the third time minus the initial time minus the pre-specified delay for RTT estimation.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, on a first carrier having a first subcarrier spacing (SCS), a scheduling indication via a physical downlink control channel (PDCCH) scheduling a downlink transmission on a second carrier having a second SCS. The UE may process the downlink transmission on the second carrier based at least in part on a delay between the PDCCH and the scheduled downlink transmission and a timing threshold having a basic term and an adjustment term. For example, the basic term may be based at least in part on a minimum delay between the PDCCH and the scheduled downlink transmission, and the adjustment term may be based at least in part on a processing time due to a difference between the first SCS and the second SCS. Numerous other aspects are provided.

Abstract: This disclosure provides methods, devices, and systems for multi-level configuration and reporting for positioning in new radio (NR) wireless communications systems. In some wireless communications systems, a network entity may determine a position or location of a supported user equipment (UE) using radio access network information. The information may be associated with UE-assisted positioning techniques, such as a positioning reference signal (PRS) transmission by the base station and reporting of radio signaling measurements by the UE. The UE may support a multi-level configuration for reporting the radio signaling measurements, including determined report quantities on one or more of a resource level, a set level, or a setting level for the PRS transmission, or generally for the network entity. The described techniques may improve robustness associated with the reporting and, in some examples, reduce signaling overhead associated with determining a positioning and location of the UE.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives assistance data for enabling the UE to estimate a location of the UE, the assistance data including a relative location of each of a plurality of transmission points, wherein the relative location is represented as a hierarchy of two or more levels of description, wherein a highest level of description is relative to a fixed reference point, receives, from each of at least a subset of the plurality of transmission points, at least one positioning reference signal, and estimates the location of the UE based on characteristics of reception of the at least one positioning reference signal from each of the subset of the plurality of transmission points and the two or more levels of description and the fixed reference point for each of the subset of the plurality of transmission points.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives at least one of a first type of sounding reference signal (SRS) configuration or a second type of SRS configuration, wherein the first type of SRS configuration is based on a first set of available configurations for SRS received over a first higher layer protocol signaling of a component carrier, wherein the second type of SRS configuration is based on a second set of available configurations for SRS received over a second higher layer protocol signaling, and wherein the first higher layer protocol signaling is different from the second higher layer protocol signaling, and transmits one or more SRS-for-positioning purposes based on the first or second type of SRS configuration.
