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: Disclosed are a system, apparatus, and method for refined RF signal processing of a received low bandwidth signal. A first time domain RF signal is received and converted from a time based domain to a frequency based domain. A second time domain RF signal is received at a time after the first time domain RF signal and converted from a time based domain to a frequency based domain. At least the converted first RF signal and the converted second RF signal are combined, where one or both of: the converted first RF signal, or the converted second RF signal are rotated in the frequency domain for the combining. A refined time domain peak is determined from the combined RF signal.

Abstract: Techniques disclosed herein are directed toward make use of known wireless transmit station geometry (e.g., from a cell location database/almanac) to create an optimized search window, where the size of the search window is a function of an angle between a line from the center of the region of position uncertainty of the mobile device to the location of the reference transmit station, and a line from the center of the region of position uncertainty of the mobile device to the location of the remote transmit station. Techniques can be utilized for various types of wireless transmit stations not only in cell networks, but Global Navigation Satellite Systems as well.

Abstract: Techniques are provided for positioning of a mobile device in a wireless network using directional positioning reference signals (PRS), also referred to as PRS beamforming. In an example method, a plurality of directional PRSs are generated for at least one cell for a base station, such that each of the plurality of directional PRSs comprises at least one signal characteristic and a direction of transmission, either or both of which may be distinct or unique. The plurality of directional PRSs is transmitted within the at least one cell, such that each of the plurality of directional PRSs is transmitted in the direction of transmission. A mobile device may acquire and measure at least one of the directional PRSs which may be identified using the associated signal characteristic. The measurement may be used to assist position methods such as OTDOA and ECID and to mitigate multipath.

Abstract: Method, device, computer program product, and apparatus to enable mobile device position optimization and reporting are described. Signals provided by a plurality of base transceiver stations (BTS) are received to determine a BTS-based position of the mobile device. A reference position of the mobile device is determined. A range measurement with respect to a target BTS is determined. In one aspect, one or more unreliable BTSs may be detected and reported based on a positioning measurement quality, a range measurement quality, or combinations thereof. In one aspect, the positioning measurement quality is determined based on a difference between the reference position of the mobile device and the BTS-based position of the mobile device. In one aspect, the range measurement quality is determined based on a difference between a measured range/distance and a reference/expected range/distance.

Abstract: Methods, systems, computer-readable media, and apparatuses for crowdsourcing the synchronization status of a network are presented. In various embodiments, a server receives a synchronization status of a base station associated with the network. If the synchronization status indicates that the network is synchronous, the server collects information for computing time correction data. The server may send the time correction data to the mobile device for use in determining the position of the mobile device when the mobile device is connected to the synchronous network.

Abstract: A wearable device that can receive a plurality of Global Navigation Satellite System (GNSS) timing signals using an antenna, where the antenna is located in an exterior portion of the wearable device such that the antenna receives GNSS signals at the external portion of the wearable device, without the GNSS signals first passing through an air gap within a housing of the wearable device. The wearable device is configured to determine a geographic location of the wearable device based at least in part on the GNSS signals. The wearable device is configurable to perform underwater dead-reckoning procedures, measuring energy levels during dwell periods, measuring efficiency of swim strokes, sharing wearable device information with other electronic devices, calibrating the wearable device, or a combination thereof.
