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.

Abstract: Methods, systems, computer-readable media, and apparatuses for determination of multipath for determining a location of user equipment (UE) are presented. In some embodiments, the UE may, based on a first indication of signal strength associated with a first polarization type, and a second indication of signal strength associated with a second polarization type, determine an indication of multipath reflection along a path of signal propagation between a space vehicle (e.g., GNSS satellite) and the UE. Circularly polarized positioning signals may be received by the UE via natively present linearly polarized antennas and converted into circularly polarized signals. Converted circularly polarized signals may include right-handed and left-handed components, and signal strengths for each component may be compared to determine the presence of multipath. Positioning signals may be given a weight or disregarded based on the multipath determination when determining the position of the UE.

Abstract: Disclosed are a system, apparatus, and method for estimating an absolute time. A mobile device receives a first timing signal of a terrestrial base station. The mobile device obtains a first timing offset, wherein the first timing offset is a transmit time bias between the first timing signal and an absolute Global Navigation Satellite System (GNSS) time, and the mobile device receives a maximum serving distance of the terrestrial base station. The mobile device estimates the absolute GNSS time based on the first timing signal, the first timing offset, and the maximum serving distance of the terrestrial base station.
