Methods and apparatuses for positioning based on signal correlation function characteristics feedback

A wireless communication device (WCD) configured to communicate with a network having a plurality of base stations, the wireless communication device comprising:

• a transceiver;
• a processing circuit;
• and
• a storage storing instructions that, when executed by the processing circuit, cause the WCD to:
• determine, for each base station from the plurality of base stations, a reference time lag and a first time lag, the reference time lag and the first time lag being determined based on a signal received from the base station, and
• transmit a report to the network, the report comprising a relative time lag for each base station from the plurality of base stations, wherein the relative time lag represents a difference between the first time lag and the reference time lag.

A network node in a communication network having a plurality of base stations, the network node being configured to communicate with a wireless communication device (WCD), the network node comprising:

• a processing circuit,
• a computer readable medium coupled to the processing circuit, said computer readable medium containing instructions executable by the processing circuit, whereby the network node is operative to:
• receive, from the WCD, a report comprising a relative time lag for each base station from the plurality of base stations, wherein the relative time lag represents a difference between a first time lag and a reference time lag determined at the WCD based on a positioning reference signal transmitted from the base station;
• and
• determine a position of the WCD using the relative time lags.
