Utilizing a reference signal for indoor positioning

An apparatus comprising:

• a mobile device comprising:
• a wireless transceiver to communicate with an electronic communications network;
• and
• one or more processors to:
• receive, at said mobile device, a directed beam transmitted by a wireless transmitter via a wireless signal in a sequence of directional angles in a horizontal plane, said wireless signal having been encoded with an indication of a directional angle of said sequence of directional angles of said directed beam;
• decode said wireless signal to obtain said indication of said directional angle;
• obtain at least one time of arrival (TOA) measurement related to said directional angle of said sequence of directional angles of said directed beam;
• and
• determine a location of said mobile device based, at least in part, on said at least one TOA measurement and said indication of said directional angle.

A non-transitory storage medium having instructions executable by a processor to:

• receive, at a mobile device, a directed beam transmitted by a wireless transmitter via a wireless signal in a sequence of directional angles in a horizontal plane, said wireless signal having been encoded with an indication of a directional angle of said sequence of directional angles of said directed beam;
• decode said wireless signal to obtain said indication of said directional angle;
• obtain at least one time of arrival (TOA) measurement related to said directional angle of said sequence of directional angles of said directed beam;
• and
• determine a location of said mobile device based, at least in part, on said at least one TOA measurement and said indication of said directional angle.
