    Abstract: Methods for mobility indication of wireless Access Points (APs) are disclosed. An AP may determine mobility indication information, based, in part, on at least one of: configuration information on the AP pertaining to mobility; and/or wireless signal measurements associated with the AP, and/or captured images associated with the AP, and/or sensor measurements associated with the AP. The AP may transmit the mobility indication information for the AP. The mobility indication information may indicate that the AP is mobile and/or characterize the mobility. The mobility indication information may further include a request to remove information associated with the AP from location determination databases, location assistance databases, and/or base station almanacs. Disclosed methods also pertain to a User Equipments (UE), which may receive wireless signals with mobility indication information associated with an AP; and determine a suitability of the AP for determining the UEs location based on the received mobility indication information.

    Abstract: Approaches for enhancing range-based position determination using pairwise error detection and compensation are provided. One method for enhancing a position estimate of a first node may include performing measurements at the first node using a signal received from a second node, and receiving measurements from the second node. The received measurements may be performed at the second node using a signal provided by the first node. The method may further include determining pairwise comparisons of the performed measurements and the received measurements, and compensating the measurements performed at the first node, based on the pairwise comparisons, for estimating the position of the first node. Systems and apparatuses for performing the various position determination methods are further presented.

    Abstract: Disclosed are implementations, including a method, performed at a processor-based mobile device, that includes receiving at the mobile device antenna information for a wireless node, including a transmitter gain for the wireless node in at least one message transmitted to the mobile device. The at least one message includes, a beacon frame message, a fine timing measurement (FTM) protocol-based message, and/or an assistance data message transmitted from a remote central repository. The method also includes deriving an estimate of a receiver gain for a receiver of the mobile device based, at least in part, on the transmitter gain for the wireless node, and adjusting one or more signal strength values determined for signals received from the wireless node based on the estimate of the receiver gain of the receiver of the mobile device derived based, at least in part, on the transmitter gain for the wireless node.

    Abstract: Systems, apparatus and methods for estimating a location of a mobile device are presented. Before computing a location estimate, the mobile device groups a plurality of access points into two or more categories (for example, a first list of access points having a first characteristic and a second list of access points having a second characteristic). Round-trip time (RTT) measurements are computed for access points in the first list. A Short Interframe Space (SIFS) value may be determined for each access point in the first list or generally SIFT representing the first list as a whole. The RTT measurements are compensated with the appropriate SIFS value. The mobile device then computes its location or position fix estimate using the compensated RTT values while excluding less accurate RTT values from other access points. As a result, the location estimate eliminates adverse influent from some access points.
