Abstract: Methods, apparatus and computer program products for providing an autonomously organizing network enable a cellular network to maintain stable operation despite unpredictable addition or removal of network devices. In addition, a network operator can create a scalable deployment that provides for operational efficiency and reduced cost burden of new equipment by enabling many existing processes to remain relevant. A method for providing such a network provides for collecting radio data from a first peer device, collecting topological data from the first peer device or a second peer device, creating a message from the topological and the radio data, and sending the message to a network device.

Abstract: Apparatus and methods for power control for mitigation or control of interference in a wireless communications environment. Power control techniques can consider the effectiveness of interference cancellation before making power control determinations. For example, where interference with a base station from an interfering wireless terminal is being canceled such that the effects of that interference are not adversely affecting operations of the base station, the offending terminal can be left unchanged, or its transmit power can be increased. On the other hand, where the interference cancellation operation is not able to cancel the effects of the interfering signal sufficiently, the operation can lower the uplink transmit power of the offending signal so as to not cause interference to the other base station.

Abstract: A method for assigning downlink transmit power levels to radio nodes (RNs) in a small cell radio access network (RAN) includes assigning initial power levels to the RNs. For each cell, first events are counted indicating that UEs receiving a signal from their serving cells with a signal strength below a specified value have entered a coverage hole. For each cell, second events are counted indicating that UEs have re-established a previous connection on one of the cells. For each pair of cells, a coverage hole is identified between them if the number of first events for one cell exceeds a threshold and a number of second events or re-establishment of a previous connection on the other cell exceeds another threshold. For each identified coverage hole, the downlink transmit power level is increased of at least one RN in the pair of cells between which the coverage hole is identified.

Abstract: Methods and apparatus are described that enable a deployment of a system of wireless nodes, e.g., femtocells, which can self-configure themselves into a balanced and optimized wireless network. In various embodiments, access points switch between a network monitoring mode in which network monitoring is performed and a communications mode in which the access point serves one or more wireless terminals and communicates traffic data to/from the wireless terminals. Traffic data transmission to wireless terminals are not supported in network monitoring mode. Based on information gathered from one or more access nodes while they operating in network monitoring mode of operation, access point configuration information is generated and one or more access points are automatically configured.

Abstract: Methods, devices, and computer program products facilitate various handoff operations to/from a network. A self-configuring and self-optimizing topology discovery operation provides detailed information regarding the various radio nodes that are internal and external to the network. This information is utilized to construct a plurality of neighbor lists that identify multiple tiers of neighboring radio nodes of the network. The neighbor lists and the measurements obtained from the user equipment within the network provide up-to-date information that facilitates various types of handoff operations.

Abstract: Methods, devices and computer program products facilitate self-configuration and self-optimization of radio networks. An internal topology discovery is performed to assess characteristics of a plurality of access points within an internal network. An external cell discovery can also be performed to identify one or more access points operating within an external network. Based on the assessments obtained through the internal and/or external toplogy dicovery processes, operational parameters are assinged to each access point within the internal network. Such operational parameters can include a transmit power associated with each radio node.
