Room and floor level position location scheme

A method for indoor tracking, comprising:

• transmitting, by a device, information to determine an estimate of a location of the device in an indoor environment;
• receiving an instruction to enable the device to detect energy signals for a specified period of time, the instruction being scheduled based on two or more candidate spaces for the device that are obtained from the location estimate of the device;
• and
• reporting whether an energy signal is detected during the specified period of time to determine the candidate space of the two or more candidate spaces in which the device is located.

A system for indoor tracking, comprising:

• means for determining two or more candidate spaces for a device in an indoor environment based on an estimate of a location of the device;
• means for scheduling transmission of at least one energy signal from within each of the two or more candidate spaces at a different time;
• means for scheduling energy detection for the device at the different times that the energy signals are being transmitted from within each of the two or more candidate spaces;
• and
• means for identifying, based on which of the transmitted energy signals is detected by the device, the one candidate space of the two or more candidate spaces in which the device is located.
