Abstract: Methods, systems, and devices for transmit power control for positioning using non-serving cells are described. A user equipment (UE) may determine that an uplink reference signal may be associated with a positioning procedure. In some cases, the positioning procedure may include transmission, by the UE, of the reference signal to a non-serving cell, which may be farther away from the UE than a serving cell. The UE may determine an absence of a parameter associated with a transmit power for transmitting the reference signal. Based on the absence, the UE may determine the transmit power based on parameters received from a serving cell, based on configuration information, based on a message intercepted from the cell other than the serving cell, or based on other considerations or information.

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may return to acquisition mode after a predetermined number of positioning occasions or if the selected beams are no longer valid due to movement or change in conditions.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: A method of user equipment (UE) positioning includes receiving positioning assistance data associated with a Transmission Reception Point (TRP), such as an expected Reference Signal Time difference (RSTD) between a reference cell and the TRP. The method also includes capturing, based on at least the expected RSTD, a first portion of reference signals from the TRP, where, at the UE, the first portion of the reference signals does not overlap in time with non-reference signals from the reference cell. The method further includes determining a first Time of Arrival (TOA) of the reference signals from the TRP based on the first portion of the reference signals.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus for on-demand positioning. For example a method may include transmitting a request to participate in a UE positioning procedure, wherein the request indicates one or more parameters to be used by a location server in coordinating one or more base stations (BSs) to participate in the UE positioning procedure, and receiving signaling from the location server configuring the UE to participate in the UE positioning procedure.

Abstract: Techniques are provided for enabling on-demand positioning reference signals (PRS) with a user equipment (UE). An example method for determining a location of a mobile device includes sending a request for downlink positioning reference signals to a network server, where the request includes positioning reference signal configuration information, receiving assistance data based on the positioning reference signal configuration information, measuring one or more downlink positioning reference signals based at least in part on the positioning reference signal configuration information, and determining a location of the mobile device based at least on part on the measurements obtained from the one or more downlink positioning reference signals and the assistance data.

Abstract: Disclosed are various techniques for wireless communication. 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: Techniques are provided for time-domain processing of DL-PRS signals under certain conditions in which time-domain processing has a computational advantage over frequency-domain processing. Because of this, embodiments can provide positioning at a lower computational cost than positioning provided by traditional techniques utilizing only frequency-domain processing. This reduced computational cost can improve the battery life of mobile devices, ultimately resulting in a better user experience.

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.
