    Abstract: An example communication system includes remote units to exchange radio frequency (RF) signals with mobile devices, RF signals comprising information destined for, or originating from, a mobile device, the remote units performing at least some physical layer processing for an air interface used by the remote units to communicate with the mobile device. The communication system also includes two or more controllers comprising real-time schedulers for assigning airlink resources to the mobile device for the information. The communication system also includes a coordination function coupled to the two or more controllers to coordinate assignments made by the real-time schedulers in the two or more controllers.

    Abstract: One embodiment is directed to a system to provide wireless service to user equipment using licensed radio frequency spectrum and unlicensed RF spectrum. The system comprises a controller and a plurality of radio points to transmit and receive radio frequency signals to and from the user equipment using the licensed RF spectrum. The system further comprises a wireless termination to transmit and receive radio frequency signals to and from the user equipment using unlicensed RF spectrum. The controller is configured to use a mobility group for providing the wireless service to the user equipment using the unlicensed RF spectrum and a plurality of WLAN access points. The controller is configured to establish an interface with the wireless termination for the mobility group to communicate control plane data to the wireless termination associated with providing the wireless service to the user equipment using the unlicensed RF spectrum. Other embodiments are disclosed.

    Abstract: One embodiment is directed to a system to provide wireless service comprising a base band unit and a plurality of antennas communicatively coupled to the base band unit. The system is configured for frequency reuse implemented via the plurality of antennas in order to transmit to subsets of the UEs. The UEs included in each subset are transmitted respectively different data using the same resource elements. The system is configured to collect base station data including Channel Quality Information (CQI) data, Sounding Reference Signal (SRS) data, and hybrid automatic repeat request (HARQ) acknowledgement/negative acknowledgement (ACK/NACK) data for the plurality of UEs. The system is configured to use the base station data to determine candidate UEs for transmission to using frequency reuse and to determine modulation and coding schemes (MCSs) for the UEs transmitted to using frequency reuse.

    Abstract: A C-RAN includes a plurality of remote units; and a central unit communicatively coupled to the remote units via a fronthaul network. The central unit is configured to determine sets of data to be sent to respective subsets of remote units across the fronthaul network. The central unit is also configured to determine a mapping of each of the sets of data to a respective one of the subsets of remote units. The central unit is also configured to, for each of the sets of data, if at least one of the multicast groups wholly contains the respective subset of remote units mapped to that set of data, transmit that set of data to the respective subset of remote units over the fronthaul network by multicasting that set of data to the multicast group that best matches the respective subset of remote units mapped to that set of data.

    Abstract: A system for reporting UE measurements is disclosed. The system includes a spectrum access system (SAS) configured to allocate a frequency band in the system, a coexistence manager (CxM) communicatively coupled to the SAS and allocate a set of radio frequency (RF) channels within the frequency band. The system also includes one or more CBSDs communicatively coupled to the SAS and CxM and configured to provide wireless service to user equipment (UEs) using one or more of the RF channels allocated by the CxM. The CxM is configured to manage co-existence of the CBSDs and advise the SAS on how to allocate the RF channels based, at least in part, on aggregated measurement reports provided to the CxM from the CBSDs.
