    Abstract: A Location Management Component (LMC) may be included in a gNB and connected to a gNB Central Unit (gNB-CU). The gNB-CU receives location related messages from any of (i) a UE via a gNB Distributed Units (gNB-DU), (ii) another gNB via an Xn interface, or (iii) a core network entity (e.g. AMF) via an NG interface. These messages can be transported in container messages (e.g., an RRC container for LPP messages sent to or received from a UE; an NGAP container for messages sent to or received from an AMF, or an XnAP container for messages sent to or received from another gNB). The gNB-CU removes the location related messages from the container messages and forwards them to an LMC using F1-AP container messages. Location related messages sent from an LMC to other entities are transported in a reverse manner through a gNB-CU using corresponding container messages.

    Abstract: Techniques for supporting positioning for a terminal (sometimes referred to herein as a target device) in a wireless network are described. In an aspect, positioning for a target device includes transmitting a Request Assistance Data message to a location server, the Request Assistance Data message indicating at least one positioning method from a plurality of supported positioning methods. The Request Assistance Data message comprises common parameters that are applicable to all positioning methods indicated in the Request Assistance Data message. The common parameters comprise a serving cell identifier. Positioning for the target device further includes receiving assistance data sent in response to the Request Assistance Data message, and performing positioning based on the received assistance data.

    Abstract: This disclosure provides methods, devices, and systems for beam group reporting for positioning in new radio (NR) wireless communications systems. In some wireless communications systems, multiple PRS resources, e.g., a beam group, received by a user equipment (UE) from the same network entity may be used to produce a combined Time of Arrival (TOA) measurement for the reference or target to derive an Reference Signal Time Difference (RSTD) estimate. The UE provides to a network entity an indication of the PRS resources in the beam group, which may be specifically or generally identified. Additionally, parameters associated with the beam group are provided, such as a relative quality of the TOA measurement for each PRS resource in the subset, a spread of the TOA measurements in the subset, a relative signal strength of each PRS resource in the subset, or a spread of the signal strength in the subset.

    Abstract: Disclosed are techniques for determining a distance (or range) between a first wireless entity and a second wireless entity. In an aspect, the first wireless entity transmits a first positioning reference signaling (PRS) signal to the second wireless entity at a first time, where the first PRS signal is received by the second wireless entity at a second time, and receives a second PRS signal from the second wireless entity at a third time, where the second PRS signal is transmitted by the second wireless entity at a fourth time. The first wireless entity enables the distance to be determined by a location computing entity, for example, by a location server, based on the first, second, third, and fourth times. The first wireless entity may be a mobile device or a base station and the second wireless entity may be the other of the mobile device or base station.

    Abstract: Disclosed embodiments pertain to the obtaining and utilization of Observed Time Difference of Arrival (OTDOA) assistance data. Cell timing information obtained based on measurements by a Mobile Station (MS) of neighbor cells may comprise cell timing offsets of the neighbor cells relative to a serving cell for the MS. OTDOA assistance data may be generated, where the OTDOA assistance data may comprise an OTDOA assistance data reference cell and a cell timing offset between the serving cell and an OTDOA assistance data reference cell, the reference cell being selected based on the received neighbor cell measurements. Embodiments disclosed also pertain to methods on an MS for performing measurements of neighbor cells comprising cell timing information for neighbor cells by requesting idle periods with a desired length from a base station to perform the measurements, and performing the requested measurements upon receiving confirmation that the idle periods have been configured.
