In an aspect, a user equipment (UE) transmits, to a serving base station, in one or more active bandwidth parts (BWPs) of the UE, a request for a no-downlink-scheduling gap, the request including at least time-domain parameters related to scheduling the no-downlink-scheduling gap, receives, from a neighboring base station, in the one or more active BWPs, a downlink positioning reference signal (DL-PRS) during the no-downlink-scheduling gap, and transmits, in the one or more active BWPs, an uplink positioning reference signal (UL-PRS) during the no-downlink-scheduling gap in response to reception of the DL-PRS.

Abstract: In an approach for detecting non-obvious relationships between entities from visual data sources, a processor calculates a co-occurrence frequency score for an entity pair from visual data. A processor calculates a distance proximity score for the entity pair from the visual data. A processor determines an event type in the visual data. A processor determines a timeline relationship in the visual data. A processor calculates a relationship score based on the co-occurrence frequency score, the distance proximity score, the event type, and the timeline relationship. A processor detects a relationship between the entity pair based on the relationship score.

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 and base station are enabled to support improved positioning accuracy in the presence of phase noise in high frequency radio network, such as in 5G New Radio network operating in mmWave. Phase Tracking Reference Signal (PTRS) may be transmitted with Positioning Reference Signals (PRS) and used for positioning and/or used to correct the phase offset between symbols in the PRS. A request may be made to transmit PTRS alone or with the PRS, or that the PRS is transmitted with a specific PRS frame structure, e.g., with a specific comb value, that minimizes the impact of phase noise. The PTRS or a phase ramp of the staggered symbols in the PRS may be used to estimate and correct the phase offset. Less than all of the symbols transmitted in the PRS may be used to generate positioning measurements to minimize the impact of phase noise.

Abstract: Aspects presented herein may improve the efficiency, accuracy, and/or latency of a UE positioning procedure by enabling mobility analytics associated with a UE or a set of UEs to be exchanged between a location server and an NWDAF, either directly or via another network entity. In one aspect, a first network entity transmits a request for mobility data associated with a set of UEs, where the request for the mobility data is transmitted for a second network entity associated with mobility data analytics. The first network entity receives, based on the request, an indication of the mobility data associated with the set of UEs. The first network performs at least one location function for at least one UE in the set of UEs based on the indication of the mobility data.

The network entity may be a location server or location management function.

Abstract: In an aspect, a network component (e.g., BS, LMF, etc.) determines a configuration of a first search window associated with a downlink positioning reference signal (DL-PRS) resource from a transmission reception point (TRP) to a user equipment (UE) and a second search window associated with the DL-PRS resource from the TRP to the UE. The network component transmits the configuration to the UE. The UE performs one or more positioning measurements of the DL-PRS resources based on the first and second search windows.

Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques allow a user equipment (UE) to efficiently identify a trigger state that is linked to a configuration for receiving and measuring reference signals from a transmission and reception point (TRPs). The UE may receive an indication of different lists of trigger states associated with different TRPs, and, when the UE receives downlink control information (DCI) indicating a trigger state index, the UE may reference an appropriate list to identify the trigger state corresponding to the trigger state index. In particular, the UE may determine a control resource set (CORESET) pool index of a CORESET in which the DCI is received, and the UE may identify the trigger state corresponding to the trigger state index from a list of trigger states associated with the CORESET pool index.

In an aspect, a user equipment (UE) monitors one or more physical downlink control channel (PDCCH) candidates in a search space while in a radio resource control (RRC) inactive state, receives, while in the RRC inactive state, a positioning paging message from a network entity on at least one PDCCH candidate of the one or more PDCCH candidates, the positioning paging message configured to trigger an update to one or more parameters associated with an ongoing positioning session involving the UE, applies, while in the RRC inactive state, the update to the one or more parameters, and transmits, while in the RRC inactive state, an acknowledgment to the network entity in response to reception of the positioning paging message.

Abstract: The present disclosure involves systems, software, and computer implemented methods for automated message processing. Information associated with a failure message generated in response to process integration failure between two computer-implemented applications is received. The two computer-implemented applications include a sender application and a receiver application. The information includes a sender application/receiver application interface and details that caused the failure. Using the received information, multiple failure message similar to the failure message are identified. The identified messages were generated in response to the same process integration failure between the two computer-implemented applications. For either the sender or the receiver application, a resolution class operation executable to rectify the process integration failure is identified. The resolution class operation is simultaneously executed for all of the multiple failure messages.

Abstract: Systems and methods for peer-to-peer video data transfer on demand from an edge data storage device to a browser are described. A media device, such as a surveillance video camera, may include a media server and a WebRTC peer application. The media server may send media stream files using a first data transfer protocol to the WebRTC peer application in the media device. Using a second data transfer protocol, the WebRTC peer application on the media device may establish a secure peer-to-peer connection to a connection handler on a user device. The connection handler on the user device may provide the media stream files to an internet browser on the user device and the internet browser may display the media from the media stream file using an HTTP Live Streaming (HLS) library.

Abstract: Systems and methods for peer-to-peer video streaming from an edge data storage device to a browser are described. A surveillance video camera may establish a secure peer-to-peer connection using a first data transfer protocol with a user device. Once the secure peer-to-peer connection is established with the user device, out of band key exchange may occur through the peer-to-peer connection. Then, a shared key may be generated at both the video camera and the user device such that a request for media from the user device may be sent to a relay server over a second data transfer protocol. The video camera may then send an encrypted data file responsive to the media request over the second data transfer protocol to the relay server.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) maintains timing information for each of a plurality of beam pairs, each beam pair comprising a downlink (DL) beam pair, comprising a base station transmit beam and a UE receive beam or a sidelink (SL) beam pair, comprising a UE transmit beam and a UE receive beam.

In an aspect, a receiver device receives, from a network entity, a request to report a power delay profile (PDP) similarity metric for a first positioning frequency layer on a first component carrier and a second positioning frequency layer on a second component carrier; determines a first PDP for a first reference signal received on the first positioning frequency layer and a second PDP for a second reference signal received on the second positioning frequency layer; determines the PDP similarity metric based on the first PDP and the second PDP; and transmits, to the network entity, the PDP similarity metric.

Abstract: A user equipment (UE) associated with a wireless network determines a first reference signal time difference value. The UE determines a first RSTD estimate and a first RSTD uncertainty associated with the first RSTD value, identifies a search interval for the first RSTD value, the search interval extending from a difference between the first RSTD estimate and the first RSTD uncertainty to a sum of the first RSTD estimate and the first RSTD uncertainty, receives wireless signals during the identified search interval, determines a Fast Fourier Transform (FFT) window offset for decoding a first positioning reference signal (PRS) received during the identified search interval, and determines the first RSTD value based at least in part on the determined FFT window offset.

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: Techniques described herein provide for a mobile device communicating a timing quality metric related to an uplink (UL) signal for UL and/or downlink-uplink (DL-UL) positioning techniques. The timing quality metric can be indicative of an accuracy of the transmission timing of one or more reference signals (e.g., in relation to a downlink (DL) signal or other UL reference signal) and may be communicated using an indexed and/or enumerated value. This information can be included as an information element (IE) in a report provided by the mobile device to a receiving network entity or location server.

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.
