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.

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: Methods and systems for wireless communication are provided. In one example, a method comprises: receiving, by a mobile device, a radio beam, the radio beam being a directional beam that propagates along an angle of departure with respect to an antenna that transmits the radio beam; identifying, by the mobile device, at least one of: the radio beam or a base station that operates the antenna; determining, by the mobile device, a position of the mobile device based on identifying at least one of the radio beam or the antenna of the base station; and outputting, by the mobile device, the position of the mobile device.

Abstract: Disclosed are a system, apparatus, and method for optimizing GNSS search. A first radio signal is received from a terrestrial base station and a coarse location of the mobile device is estimated. A first time offset of the terrestrial base station to a timing signal of a target satellite is determined for locating a position of the target satellite. A distance from the position of the target satellite to the estimated coarse location of the mobile device is determined. A GNSS search is performed based on the distance from the target satellite and the first time offset of the first radio signal from the first terrestrial base station.

Abstract: Techniques described herein are directed to increasing a quantity of location-related information broadcast by wireless nodes. In one embodiment, a user equipment (UE) sends a request to a wireless node for broadcast of an increased quantity of location-related information for a wireless access type and the wireless node broadcasts the increased quantity of location-related information using the wireless access type. The wireless node may transfer the request to other wireless nodes which may similarly broadcast the increased quantity of location-related information using the wireless access type. The UE may receive the increased quantity of location-related information using the wireless access type and may then obtain location information such as a location estimate for the UE. In some embodiments, the increased quantity of location-related information may comprise a positioning reference signal or location assistance data.

Abstract: Methods, systems, computer-readable media, and apparatuses for determining a position of a mobile device connected to a network are presented. In various embodiments, the mobile device obtains a synchronization status of the network associated with one or more base stations. If the synchronization status indicates that the network is synchronous, the mobile device determines the position of the mobile device using previously collected crowdsourced time correction data for the synchronous network.
