  • Patent number: 10404866
    Abstract: A system and method in various embodiments implements a virtual spectrum band stacking technique facilitating spectrum sharing by converting and combining spectrum bands consisting of several different RF channels, common air interfaces, and radio channel protocols in the radio frequency channel domain to form IP Virtual Radio Channels (IP-VRCs) in the packet data domain. This virtual spectrum stacking technique combines the transmissions of contiguous and non-contiguous RF channels with differing physical layers into IP-VRCs. This technique enables simultaneous parallel high-speed wireless transmission; virtual radio channel hopping for enhanced security; and customized security schemes for different IP-VRC Groups. The deployment of the combination of IP-VRC Groups; Universal “Small Cell” Base Stations; and Universal Wireless End-Point Devices allows the aggregation of all available spectrum bands for use within a building environment.

  • Patent number: 10136448
    Abstract: Methods for enabling and disabling of muting patterns in Radio Access Network, RAN, nodes allow better detection and use of reference symbols used for synchronization. In some embodiments, coordination of muting patterns amongst different nodes is enabled, so that muting of multiple nodes results in increased protection from interference for the node in need of detecting the synchronization reference symbols. An example method is implemented in a base station operating in a wireless communications network, for facilitating over-the-air synchronization by a neighboring base station. This method includes receiving (1210) a request for activation of a reference signal muting pattern for a cell supported by the base station and activating (1220) the reference signal muting pattern in response to the request. The method further includes sending (1225) a message requesting activation of a reference signal muting pattern for a cell supported by a second base station, in response to the request.
