  • Publication number: 20160309463
    Abstract: A node in a wireless communication system includes a transceiver that operates according to a first radio access technology (RAT). The transceiver is to measure a medium usage by one or more other nodes that operate according to a second RAT. The transceiver alternately transmits in a first time interval and bypasses transmission in a second time interval. The first and second time intervals repeat with a duty cycle. The transceiver is to puncture the first time interval with one or more silent gaps. The node also includes a processor to determine a duration of the one or more silent gaps is based on the medium usage.

  • Publication number: 20160183131
    Abstract: Mobile units are handed over from LTE to carrier grade WiFi. The LTE can be licensed (LTE-L) or unlicensed (LTE-U). Charging mechanisms for co-located and integrated WiFi are also provided. When an LTE-U capable mobile unit moves into the LTE-U coverage area of a small cell, the mobile unit can use the unlicensed spectrum for a data session, thereby effectively increasing the data capacity of the network. When the mobile unit moves within the carrier grade Wi-Fi coverage area of the small cell, the small cell can handover the entire data session to the carrier grade Wi-Fi access point, thereby freeing up LTE system resources to provide data services to other mobile units.

  • Patent number: 9357482
    Abstract: A method and system for dynamic power control for next generation LTE base stations are described herein. More particularly, a dynamic power control management process may run, for example, in an OA&M module on the control plane core of the base station. The dynamic power control management process collaborates with various components, such as a call management processing module and a transport process module, to periodically obtain information regarding the number of active calls as well as the uplink and downlink data rates for a given interval for a particular cell. The dynamic power control management process polls the call management processing module and transport process module periodically according to a tunable parameter for the key values. Based on this information, the dynamic power control management process determines whether a particular cell on the base station is running below a threshold at which dynamic power control could be triggered.

  • Publication number: 20160066204
    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.

  • Patent number: 8730790
    Abstract: A method and system that helps to ensure that any cell crash (i.e., an involuntarily action occurring as a result of a software bug or malfunction) is localized to a single cell on a single modem board that supports multi-cell configuration. In this regard, the control plane and the remaining cells that are configured on the modem board should remain operational. Further the operator should be able to choose to take corrective action (i.e., reboot, reconfigure, delete, or create) with regard to a cell on the modem board without impacting the operations of the other configured cells.
