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.

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: Methods and systems are disclosed for centralized self-organizing network (cSON)-aided small cell load balancing based on backhaul information. In an aspect, a cSON server receives periodic or event triggered backhaul capacity reports from each of the plurality of small cell base stations, a backhaul capacity report indicating an uplink and/or downlink capacity state of a backhaul connection over which a small cell base station of the plurality of small cell base stations is connected to a core network, determines load balancing assistance data for at least one of the plurality of small cell base stations based on the backhaul capacity reports received from each of the plurality of small cell base stations, and provides the load balancing assistance data to the at least one of the plurality of small cell base stations.
