Abstract: A periodically-transmitted reference signal can have certain proprietary properties to help to help prevent unauthorized detection and utilization of the signal. More specifically, a base station can adjust times at which a reference signal is transmitted and/or a code with which the signal is encoded. These adjustments may be based on an equation or algorithm, which can be shared with particular mobile devices as needed.

Abstract: Positioning for user equipments (UEs) in a wireless network is supported by restricting position reference signal (PRS) configuration parameters for a Transmission Reception Point (TRP) based on PRS configuration used by co-located TRPs. The PRS configuration parameters for the TRP may be restricted by restricting orthogonality of the PRS resources with respect to PRS resources from co-located TRPs to only code division multiplexing, and other types of orthogonality such as time division multiplexing and frequency divisional multiplexing are not permitted for co-located TRPs. The PRS configuration parameters for the TRP may be restricted to the same muting sequence type, e.g., inter-instance and/or intra-instance muting, as used by co-located TRPs. The PRS configuration parameters, e.g., related to orthogonality and/or muting, are not restricted with respect to non-co-located TRPs. The restrictions on the PRS configuration parameters for a TRP may be determined by a central authority, such as a location server.

Abstract: Disclosed are techniques related to wireless communication system in which a network node (e.g., a base station, gNB, etc.) may be allowed to puncture a reference signal (RS) to deliver high priority data (e.g., URLLC data) to a user equipment (UE) that is not currently being served by the network node. The RS may comprise a puncturable subset and an unpuncturable subset. The puncturable subset may comprise resources of the RS that are allowed to be punctured, and the unpuncturable subset may comprise resources of the RS that are prohibited from being punctured. The network node may transmit the RS such that unpuncturable subset indicates whether or not the puncturable subset of the RS has or has not been punctured. In this way, the network node can quickly inform whether or not the RS has been punctured to carry high priority data.

Abstract: A position of a user equipment (UE) may be determined using downlink based solutions (e.g. OTDOA), uplink based solutions (e.g. UTDOA), or combined downlink and uplink based solutions (e.g. RTT). The serving gNBs may request neighboring gNBs to produce downlink reference signal transmissions to a target UE and/or measure uplink reference signal transmissions from the target UE. The serving gNB may receive the uplink reference signal measurements from neighboring gNBs and obtain an own uplink reference signal measurement and forward to the UE or another network entity all the uplink reference signal measurements. The UE may use the uplink reference signal measurements, along with the UE's own downlink reference signal measurements to determine RTTs. The serving gNBs or another entity may keep the uplink reference signal measurements and may determine RTTs after receiving the downlink reference signal measurements from the UE.

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: 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.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) receives, from a location server, a positioning reference signal (PRS) configuration for a downlink-and-uplink-based positioning session between the UE and the location server, waits, based on a determination that a sounding reference signal (SRS) configuration for the downlink-and-uplink-based positioning session has not been received from a serving base station of the UE, for reception of the SRS configuration from the serving base station until expiration of a timer, and determines, based on the expiration of the timer, whether the SRS configuration was received.

Abstract: A mobile device supports positioning with positioning reference signals (PRS) on multiple beam by dividing the PRS processing into two separate modes, an acquisition mode and a tracking mode. In acquisition mode, the mobile device performs a fast scan of all of the beams from a base station transmitting PRS using less than the full set of resources for the PRS, i.e., less than the full bandwidth and/or less than the full number of repetitions of the PRS. The mobile device may select the best beams to use for positioning, e.g., based on signal strength metric. In tracking mode, the mobile device tracks the PRS from only the selected beams using the full set of resources for the PRS. The mobile device may return to acquisition mode after a predetermined number of positioning occasions or if the selected beams are no longer valid due to movement or change in conditions.

Abstract: Methods, systems, computer-readable media, and apparatuses for determining a UE position within a coverage sub-area of a cell based on cell identity data are presented. In some embodiments, the UE detects one more cell identities, including a cell identity of a serving cell and possibly a cell identity of a neighbor cell of the serving cell. The one or more cell identities are included in cell identity data. The cell identity data is used in a look up of a data structure that associates coverage sub-areas of a coverage area of the serving cell with most likely positions within the coverage sub-areas and with cell identities. The result of the look up indicates that the UE is positioned at a most likely position within a coverage sub-area of the serving cell.
