Abstract: Methods and apparatus for performing dynamic channel selection are provided. In an example, a method includes receiving, at a central self-organizing network server, data from an access point (AP) including a number of stations associated with the AP. The method includes calculating downlink capacities for the associated stations and selecting a channel for the AP which maximizes a pre-defined network utility that is based on the downlink capacities. Further, it is determined if the network utility gain resulting from selecting the channel exceeds a threshold when compared to a previous channel selection state. If the network utility gain exceeds the threshold, a channel change command is issued to the AP, directing the AP to use the selected channel to communicate with a specific station.

Abstract: Aspects of using a small cell deployed in a vehicle are provided. For example, identifying the location of a wireless device includes enabling communication with a positioning server (e.g., enhanced serving mobile location center (E-SMLC)) in a home network using a positioning protocol, wherein the communication is enabled using a wireless backhaul connection to a serving network, receiving a location request from the positioning server for the location of the wireless device connected to the small cell and associated with an emergency call, determining location information for the wireless device, and providing, to the positioning server through the communication, the location information. The wireless backhaul connection to the serving network may be based on a wireless local area network (WLAN) connection.

Abstract: The present disclosure presents a method and apparatus for identifying an access point (AP) for selection by an access terminal (AT). For example, the method may include receiving a probe request by one or more APs from an AT, wherein the probe request is broadcasted by the AT to the one or more APs, generating load information and Received Signal Strength Indicator (RSSI) values of the probe request at the one or more APs, identifying an AP of the one or more APs for selection by the AT, wherein the AP for selection by the AT is identified by the one or more APs based at least on the load information and RSSI values generated at the one or more APs, and transmitting information of an AP identified by the one or more APs to the AT. As such, an improved mechanism for selecting an access point may be achieved.
