  • Publication number: 20180049037
    Abstract: A base station operates according to a first radio access technology (RAT) that requires synchronization on timing synchronization boundaries. The base station acquires a channel of an unlicensed frequency band and generates a clear-to-send message that is decodable by access points that operate according to a second RAT that does not require synchronization on the timing synchronization boundaries. The base station transmits the clear-to-send message during a time interval between acquisition of the channel and a subsequent timing synchronization boundary.

  • 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: 9769836
    Abstract: A first base station selects a subset of channels of an unlicensed frequency band based on indications of energy received over the channels. The first base station transmits one or more messages instructing user equipment to monitor the subset of channels and report information indicating whether at least one second base station is transmitting over the subset of channels. User equipment monitors the subset of channels of the unlicensed frequency band in response to receiving the one or more messages from a first base station indicating the subset of channels. The user equipment transmits one or more messages including information indicating whether one or more second base stations are transmitting over the subset of channels.
