Abstract: Methods and apparatuses are disclosed that may perform simultaneous ranging operations between a requester device and each of a plurality of target devices using OFDMA-based frame exchanges while maintaining a level of accuracy comparable to ranging operations that do not use OFDMA-based frame exchanges. Tone interleaving may be used so that the ranging devices may estimate channel conditions for the full frequency spectrum of the wireless medium. For example, a unique set of two or more non-adjacent groups of OFDM sub-carrier frequencies may be allocated to each of the plurality of target devices for ranging operations.

Abstract: Crowdsourced information may be used to associate APs with a venue and creating a venue-specific information file based on this association. This can enable the mobile device to download a single venue information file for a venue in which the mobile device may stay for an extended period of time, which may alleviate or eliminate the need to download additional AP location information while at the venue.

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.
