First Claim
1. An apparatus of a user equipment (UE) configured for WLAN-based positioning, the apparatus comprising one or more processors configured to:
- decode an assistance data message, received from a location server, the assistance data message comprising WLAN location information to assist the UE in wireless local area network (WLAN) based positioning, wherein the WLAN location information is used by the UE to identify one or more WLAN access points (AP) and to provide measurements of the one or more WLAN APs to the location server;
encode a location information message for transmission to the location server, the location information message including WLAN measurement information, wherein the WLAN measurement information comprises one or more of a WLAN measurement list of measurements of signals from one or more of the WLAN APs, one or more beacon received signal strength indicator (beacon RSSI) indicators, or one or more round trip time (RTT) indicators;
decode a capability request message, received from a location server, the capability request message including a request for WLAN location capabilities from the LIE; and
encode a capability response message for transmission to the location server to indicate location capabilities of the UE according to a WLAN protocol, wherein the assistance data message received from the location server is based on the location capabilities of the UE; and
memory, configured to store the WLAN location information.

Abstract
An apparatus, computer-readable medium, and method to determine a user equipment (UE) location in a wireless network using signals from a wireless local-area network are disclosed wireless communication network entity may be configured to send WLAN assistance data to a UE. The WLAN assistance data may include a list of one or more WLAN access points (APs). The wireless communication network entity may receive location information from the UE. The location information may be based on measurements of signals from one or more of the WLAN APs. The wireless communication network entity may determine an estimate of the location of the UE based on the location information and stored information at the wireless communication network. The wireless communication network entity may determine the estimate of the location of the UE based on the measurements of the signals of the WLAN APs and a geographic position of the WLAN APs.
