Methods and apparatus for measurement reporting based on multipath characteristics of positioning reference signal resources

A location server in a wireless network configured for position determination of a user equipment (UE) in the wireless network, comprising:

• an external interface configured to communicate with entities in the wireless network;
• at least one memory;
• at least one processor coupled to the external interface and the at least one memory, wherein the at least one processor is configured to:
• send, via the external interface, positioning assistance data for the UE to a network node comprising configuration information for a plurality of positioning reference signal (PRS) resources for the network node to measure;
• send, via the external interface, a request to the network node indicating that the network node is to determine a subset of the plurality of the PRS resources for which measurement information is to be included in a location information report based on measured multipath characteristics of the PRS resources;
• and
• receive, via the external interface, the location information report from the network node including the measurement information for the subset of the plurality of the PRS resources based on the measured multipath characteristics of the PRS resources.

A method performed by a network node in a wireless network for position measurement determination for a user equipment (UE), comprising:

• receiving positioning assistance data for the UE from a location server comprising configuration information for a plurality of positioning reference signal (PRS) resources for the network node to measure;
• obtaining measurement information for the PRS resources received from other entities in the wireless network;
• measuring multipath characteristics of the PRS resources;
• determining a subset of the plurality of the PRS resources for which measurement information is to be included in a location information report based on measured multipath characteristics of the PRS resources;
• and
• sending the location information report to the location server including the measurement information for the subset of the plurality of the PRS resources determined based on the measured multipath characteristics of the PRS resources.

A network node in a wireless network configured for position measurement determination for a user equipment (UE), comprising:

• an external interface comprising at least one of a wireless transceiver and a communications interface configured to communicate with other entities in the wireless network;
