Abstract
Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) determines a validated heading of the UE, wherein the validated heading is determined based on at least navigational map data stored in a memory of the UE, and determines a dead reckoning position estimate of the UE based on at least the validated heading and sensor information from one or more environmental sensors of the UE.
Claims30
A method of wireless positioning performed by a user equipment (UE), comprising:
- determining a validated heading of the UE, wherein the validated heading is determined based on at least navigational map data stored in a memory of the UE;
- and
- determining a dead reckoning position estimate of the UE based on at least the validated heading and sensor information from one or more environmental sensors of the UE.

A user equipment (UE), comprising:
- a memory;
- at least one transceiver;
- and
- at least one processor communicatively coupled to the memory and the at least one transceiver, the at least one processor configured to:
- determine a validated heading of the UE, wherein the validated heading is determined based on at least navigational map data stored in a memory of the UE;
- and
- determine a dead reckoning position estimate of the UE based on at least the validated heading and sensor information from one or more environmental sensors of the UE.
