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: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) receives a set of antenna parameters for a plurality of antenna ports of a transmission-reception point (TRP), obtains positioning measurements of a plurality of positioning reference signal (PRS) resources transmitted on the plurality of antenna ports, reconstructs an underlying physical channel between the TRP and the UE based on the positioning measurements of the plurality of PRS resources, and determines a downlink angle of arrival (DL-AoD) measurement from the TRP to the UE based on the reconstructed underlying physical channel.

Abstract: Techniques for autonomous uplink (AUL) transmissions are provided that allow for efficient use of shared radio frequency spectrum band resources. A user equipment (UE) may determine a duration of an AUL transmission and modify an uplink waveform or provide an indication to a base station of one or more channel resources that may be available for base station transmissions, in order to more fully utilize shared radio frequency spectrum band resources within a maximum channel occupancy time (MCOT). A base station may activate or deactivate AUL transmissions through downlink control information (DCI) transmitted to the UE. A UE and base station may exchange various other control information to provide relatively efficient autonomous uplink transmissions and use of the shared radio frequency spectrum band resources.

Abstract: In an aspect, an LMF component may determine to trigger positioning-related action(s) at a UE. The LMF component may request that a serving BS of the UE trigger the positioning-related action(s). The serving BS may transmit a DCI communication with a CSI request field (e.g., that triggers at least CSI reporting, or triggers positioning-related action(s) only). The CSI request field may further be associated with positioning-related information including at least one PRS configuration, at least one positioning measurement request, at least one location reporting request, or a combination thereof. The UE may perform the positioning-related action(s) based on the positioning-related information.

Abstract: Techniques are provided for processing frequency domain non—contiguous positioning reference signals. An example method for determining a time of arrival of a frequency domain non-contiguous positioning reference signal includes receiving the frequency domain non-contiguous positioning reference signal, determining a first estimate of the time of arrival (1204) based on a narrowband processing of the frequency domain non-contiguous positioning reference signal, performing a wideband processing of the frequency domain non-contiguous positioning reference signal based on the first estimate of the time of arrival, and determining a second estimate of the time of arrival (1214) based on the first estimate of the time of arrival and the wideband processing of the frequency domain non—contiguous positioning reference signal.
