Abstract
Aspects of the disclosure are related to a method for adjusting a wireless signal scanning rate based on a pedestrian dead-reckoning (PDR) reliability level estimate. An example method adjusting a wireless signal scanning rate based on a pedestrian dead-reckoning (PDR) reliability level estimate comprises estimating a PDR reliability level, determining a wireless signal scanning rate based at least in part on the estimated PDR reliability level, wherein wireless signal scanning is performed to obtain position fixes, and performing the wireless signal scanning at the determined wireless signal scanning rate.

A method for adjusting a wireless signal scanning rate based on a pedestrian dead-reckoning (PDR) reliability level estimate, comprising:
- estimating a PDR reliability level from sensor data provided by at least one sensor during PDR;
- determining a wireless signal scanning rate based at least in part on the estimated PDR reliability level, wherein wireless signal scanning is performed to obtain position fixes;
- adjusting the wireless signal scanning rate from a first initial wireless signal scanning rate to the determined wireless signal scanning rate based on the estimated PDR reliability level during PDR;
- and
- performing the wireless signal scanning at the determined wireless signal scanning rate.
An apparatus, comprising:
- a memory;
- and
- a processor coupled to the memory, the processor configured to:
- estimate a pedestrian dead-reckoning (PDR) reliability level from sensor data provided by at least one sensor during PDR,
- determine a wireless signal scanning rate based at least in part on the estimated PDR reliability level,
- adjust the wireless signal scanning rate from a first initial wireless signal scanning rate to the determined wireless signal scanning rate based on the estimated PDR reliability level during PDR, and
- performing wireless signal scanning at the determined wireless signal scanning rate.
An apparatus, comprising:
- means for estimating a pedestrian dead-reckoning (PDR) reliability level from sensor data provided by at least one sensor during PDR;
- means for determining a wireless signal scanning rate based at least in part on the estimated PDR reliability level;
- means for adjusting the wireless signal scanning rate from a first initial wireless signal scanning rate to the determined wireless signal scanning rate based on the estimated PDR reliability level during PDR;
- and
- means for performing wireless signal scanning at the determined wireless signal scanning rate.
A non-transitory, computer-readable, storage medium storing computer executable code for adjusting a wireless signal scanning rate based on a pedestrian dead-reckoning (PDR) reliability level estimate comprising:
- estimating a PDR reliability level from sensor data provided by at least one sensor during PDR;
- determining a wireless signal scanning rate based at least in part on the estimated PDR reliability level;
- adjusting the wireless signal scanning rate from a first initial wireless signal scanning rate to the determined wireless signal scanning rate based on the estimated PDR reliability level during PDR;
- and
- performing wireless signal scanning at the determined wireless signal scanning rate.
