  • Patent number: 10182441
    Abstract: A method of operating a terminal device and network infrastructure equipment in a wireless telecommunications system for communicating on a primary cell supporting a primary component carrier on radio resources within a first frequency band and a secondary cell supporting a secondary component carrier on radio resources within a second frequency band. The infrastructure equipment establishes plural configuration settings for the secondary carrier based on measurements of radio usage in the second frequency band, which are conveyed to the terminal device. The terminal device makes channel quality measurements for the secondary component carrier according to the different configuration settings and reports these to the infrastructure equipment.

  • Patent number: 10129897
    Abstract: A method of operating a terminal device and a base station in a wireless telecommunications system to communicate with one another using a primary component carrier operating on radio resources within a first frequency band and a secondary component carrier operating on radio resources within a second frequency band. The terminal device makes measurements of radio usage in the second frequency band, and transmits an indication of the measurements to the base station. The base station then establishes a configuration setting for the secondary component carrier. The configuration setting is associated with a validity period during which the base station communicates data to the terminal device using the primary component carrier and the secondary component carrier operating in accordance with its configuration setting.

  • Patent number: 9930537
    Abstract: Apparatus, systems, and methods are disclosed for determining dynamic positioning of mobile cells. Dynamic positioning provides for navigating a mobile cell, such as an unmanned aerial vehicle or the like, to a location suitable for offloading current network traffic, such that the suitable location maximizes offloading capabilities. The methodology describes takes into account both the current traffic load on the network and the location of the highest system capacity-intensive mobile terminals in determining an initial position for deploying the mobile cell. Additionally, the location of the deployed mobile cell is optimized, over time, based on tracking the direction of movement of the highest capacity-intensive mobile terminals, and, in some embodiments, service quality indicators provided by the mobile terminals and/or contextual information captured by the mobile cell apparatus.
