Method for wireless device (wd) global navigation satellite system (gnss) local environment characterization

A network node configured to communicate with a plurality of wireless devices, WDs, the network node comprising:

• processing circuitry configured to:
• obtain a capability of the WD to provide GNSS positioning metrics;
• request the WD to provide GNSS positioning metrics with a location estimate, when a location estimate is available at the WD;
• a radio interface in communication with the processing circuitry and configured to receive from a plurality of WDs, local GNSS positioning metrics associated to a reported location estimate;
• and
• the processing circuitry being further configured to determine local GNSS positioning metrics applicable to the plurality of WDs;
• and
• the radio interface being further configured to transmit a set of local GNSS positioning metrics to be used by at least one WD.

A method in a WD configured to communicate with a network node and a plurality of satellites, the method comprising:

• transmitting to the network node a capability of the WD for providing GNSS positioning metrics;
• receiving a request from the network node to provide GNSS positioning metrics with a location estimate, when a location estimate is available at the WD;
• determining local GNSS positioning metrics based at least in part on satellite signal measurements by the WD;
• reporting the local GNSS positioning metrics with a location estimate when a location estimate is available at the WD;
• receiving GNSS positioning metrics from the network node, the GNSS positioning metrics being based at least in part on local GNSS positioning metrics received from a plurality of WDs;
• and
• determining a position of the WD based at least in part on the local and regional GNSS positioning metrics.
