Abstract

Systems, methods, and devices for performing wireless local area network (WLAN) fine timing measurement (FTM) are described. An apparatus for a user equipment (UE) includes a memory to store session information for a long term evolution positioning protocol (LPP) session with a location server. The apparatus for the UE also includes one or more baseband processors to decode a provide assistance data LPP message from the location server as part of the LPP session, the provide assistance data LPP message including WLAN assistance information; identify one or more access points (APs) based on the WLAN assistance information; and determine at least one position measurement based on an FTM procedure with the one or more identified APs.
