Abstract: Disclosed are a system, apparatus, and method for adaptive discovery and scanning of wireless access points. In one embodiment, a set of channels can be scanned in a first iteration to discover wireless access points. In one embodiment, a discovery profile based on the discovered wireless access points can be determined and in a second iteration, a subset of the set of channels can be scanned. In one embodiment, the subset consists of non-overlapping channels selected according to the discovery profile.

Abstract: Navigation solutions for a pedestrian or vehicle user are obtained by determining whether the direction and location of the user obtained from a map at least substantially conform to the direction and location of the user based on one or more measurements obtained from one or more sensors, and if the direction and location of the user obtained from the map at least substantially conform to the direction and location of the user based on one or more measurements obtained from one or more sensors, computing the navigation solutions based, at least in part, on the direction and location of the user.

Abstract: Aspects presented herein may improve/enhance camera-aided/assisted positioning by utilizing light and shadow created by an artificial light. In one aspect, a UE captures a set of images of an object using at least one camera. The UE estimates a direction of at least one light source based on a shadow of the object in the set of images, wherein the shadow of the object is created by the at least one light source. The UE calculates at least one of (1) a distance (d) between the at least one camera and a set of first features associated with the object based on the estimated direction of the at least one light source or (2) directional information of a set of second features associated with a surrounding environment that is within a threshold distance of the object.

Abstract: In some implementations, one or more devices may obtain measurement information for an epoch, the measurement information indicative of a pseudorange measurement, a carrier phase measurement, and a doppler measurement performed by a reference global navigation satellite system (GNSS) receiver of radio frequency (RF) signals transmitted by a plurality of GNSS satellites. The device(s) may obtain initial state-space representation (SSR) data comprising orbit correction, clock correction, and code bias information for the epoch. The device(s) may determine ionospheric correction data for the epoch based on the measurement information and the initial SSR data. The device(s) may determine tropospheric correction data for the epoch based on the determined ionospheric correction data, the measurement information, and the initial SSR data. The device(s) may provide the expanded SSR data, wherein the expanded SSR data includes the ionospheric correction data and the tropospheric correction data.

Abstract: Techniques are provided for utilizing reference signals transmitted by network stations to determine the orientation of a wireless node. An example method for determining an orientation of a user equipment includes determining a first location associated with the user equipment, determining a second location associated with a first wireless node, receiving, with the user equipment, a radio frequency signal transmitted from the first wireless node, determining two measurements based at least in part on the first location, the second location, and angle of arrival information associated with the radio frequency signal, determining a gravity vector based on inertial measurements obtained with the user equipment, and computing the orientation of the user equipment based at least in part on the gravity vector and the two measurements.
