Abstract: Systems and techniques are described for processing one or more maps. For example, a method can include obtaining a first map of an environment in which the computing device is located and obtaining a second map of the environment based on sensor data from one or more sensors. The method can include comparing first one or more elements of the first map and second one or more elements of the second map. Each respective element of the first one or more elements corresponds to a respective element of the second one or more elements. The method can further include determining whether to use the first map or the second map for at least one navigation function based on comparing the first one or more elements of the first map with the second one or more elements of the second map.

Abstract: A hybrid approach for using reference frames is presented in which a series of anchor frames is used, effectively resetting a global frame upon a trigger event. With each new anchor frame, parameter values for lane boundary estimates (known as lane boundary states) can be recalculated with respect to the new anchor frame. Triggering events may a based on a length of time, distance traveled, and/or an uncertainty value.

Abstract: Disclosed are techniques for wireless communication. In particular, aspects relate to configuring, triggering and/or transmitting relative and global position-orientation messages (e.g., from a vehicle equipped with sensors to enable estimation of relative and global position-orientation to a network entity).
