    Abstract: Techniques for adjusting transmit timing of base stations and user equipments (UEs) in a wireless network are described. In one operating scenario, a femto base station communicates with a femto UE, and a macro base station communicates with a macro UE located within the coverage of the femto base station. In an aspect, the transmit timing of the femto base station may be delayed relative to the transmit timing of the macro base station, e.g., to time align downlink signals from the femto and macro base stations at the femto and macro UEs. In another aspect, the transmit timing of the femto UE may be advanced relative to the transmit timing of femto base station by an amount larger than twice the propagation delay between the femto UE and the femto base station, e.g., to time align uplink signals from the femto and macro UEs at the femto base station.

    Abstract: Techniques for supporting peer-to-peer (P2P) communication in a wide area network (WAN) are disclosed. In an aspect, interference coordination between P2P devices engaged in P2P communication and WAN devices engaged in WAN communication may be performed based on a network-controlled architecture. For the network-controlled architecture, P2P devices may detect other P2P devices and/or WAN devices and may send measurements (e.g., for pathloss, interference, etc.) for the detected devices to the WAN (e.g., serving base stations). The WAN may perform resource partitioning and/or association for the P2P devices based on the measurements. Association may include selection of P2P communication or WAN communication for a given P2P device. Resource partitioning may include allocation of resources to a group of P2P devices for P2P communication. The WAN may send the results of association and/or resource partitioning to the P2P devices, which may communicate in accordance with the association and/or resource partitioning results.

    Abstract: An estimated location of an access point is generated based on identification of indoor and outdoor locations and the presumption that most access points are in an indoor location. The estimated location may be produced using location information for the access point and the identification of the indoor and outdoor locations while prioritizing the indoor location to produce the estimated location on or within a boundary of the indoor location. The location information may be, e.g., a preliminary estimated location or wireless signal measurements and associated position fixes for the access point. For example, a preliminary estimated location may be shifted to be on or within the nearest boundary of an indoor location or may be adjusted based on the location information. The estimated location may be calculated directly using weights to bias the calculation of the estimated location to be on or within the boundary of the indoor location.
