    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: Systems and methods for automatic X2-U/Xn-U link selection are provided herein. In one example, a method includes determining whether a local communication link between a first base station (FBS) and a second base station (SBS) is possible. In response to determining that the local communication link is possible, the method includes sending a request, including a local IP address for a FBS BBU, to the SBS for an address suitable for establishing a communication link. The method includes determining whether to include a local IP address for an SBS BBU in a response to the request. In response to determining to include the local IP address for the SBS, the method includes sending the response, including the local IP address for the SBS BBU to the FBS. The method includes establishing the local communication link between the FBS and SBS using the local IP addresses without using a security gateway.

    Abstract: A base station includes at least one remote unit (RU) that exchanges radio frequency (RF) signals with a user equipment (UE) using an air interface. The base station also includes a controller communicatively coupled to the at least one RU. The controller forms first RLC protocol data units (PDUs) for a first cell and second RLC PDUs for a second cell based on Radio Link Control (RLC) service data units (SDUs). A first at least one processor in the controller performs first Medium Access Control (MAC) scheduling for the first cell based on a first buffer occupancy update to produce a first scheduling decision. A second at least one processor in the controller performs second MAC scheduling for the second cell based on a second buffer occupancy update to produce a second scheduling decision.
