  • Patent number: 9918232
    Abstract: A node in a wireless communication system includes a transceiver to receive one or more configuration parameters to configure the node for communication in an unlicensed frequency band. The node also includes a processor to implement a state machine that transitions, based on the one or more configuration parameters, between an enable state in which the node supports wireless connectivity in the unlicensed frequency band, a disable state in which the node does not support wireless connectivity in the unlicensed frequency band, and a flywheel state in which the node supports wireless connectivity in the unlicensed frequency band for a predetermined time interval before transitioning to the disable state.
    Type: Grant
    Filed: April 26, 2016
    Date of Patent: March 13, 2018
    Assignee: Alcatel-Lucent USA Inc.

  • Publication number: 20170311191
    Abstract: A node increments values of performance measurement (PM) counters to indicate characteristics of at least one unlicensed frequency band used for wireless communication during a first time interval. The node provides the values of the PM counters to a controller that is configured to aggregate the values of the PM counters for the node with values of PM counters for other nodes. A controller receives values of PM counters from a plurality of nodes to indicate characteristics of wireless communication by each of the plurality of nodes using the at least one unlicensed frequency band over the first time interval. The controller aggregates the values of the PM counters for the plurality of nodes and modifies a configuration of at least one of the plurality of nodes based on the aggregated values.

  • Patent number: 8755805
    Abstract: At least one example embodiment discloses a method of generating a radio frequency (RF) map of a network. The method includes obtaining, by a controller, received signal strengths of at least one user equipment (UE) in a first technology network, determining, by the controller, a back projection of a second technology network based on the received signal strengths, and generating, by the controller, an RF map of the second technology network based on the determining. The back projection represents an attenuation function of a coverage area of the second technology network and the RF map illustrates the attenuation function of the coverage area of second technology network.
