Abstract: A dual identity cell adapted for use in a small cell RAN includes two identities that may be supported on the same hardware platform—a dedicated PCI (Physical Cell Identity as defined under LTE) identity and a common PCI identity. The dedicated PCI identity operates similarly to a cell in a regular RAN in which neighboring cells use unique PCIs so that user equipment (UE) may distinguish among cells. The dedicated PCI identity, when exposed to the UE, may be used to determine the position of a UE within the RAN so that cells within listening range of the UE are identified. Those identified cells (termed here as the “detected set”) can then transmit the same data and control signals to the UE using their common PCI identities. In this way, all the cells in the detected set appear to the UE as one single cell.

Abstract: A radio access network, such as an LTE E-RAN, employs a hierarchical architecture and includes a services node that provides connectivity between the radio nodes in the RAN and a core network. The RAN employs a hybrid coordinated scheduling scheme in which independent schedulers are running on the services node and the radio nodes. In this way the services node can allocate scheduling resources for some of the UEs in the RAN while the radio nodes can allocate scheduling resources for the remaining UEs in their respective serving cells. In some cases a prioritization approach is used in which the radio nodes do not schedule any radio resources that have already been scheduled by the services node.

Abstract: A method is shown for allocating a plurality of channels to a plurality of radio nodes (RNs) in a radio access network (RAN). In accordance with the method, an initial RN is selected from among the plurality of RNs. A first of the plurality of channels is assigned to the initial RN. The first channel is selected such that external interference experienced by the initial RN from sources other than the RAN on the first channel is minimized. A second RN is selected from among the plurality of RNs. A second of the plurality of channels is assigned to the second RN. The second channel is selected such that a metric reflective of an information carrying capacity of the RNs that have already been assigned one of the plurality of channels is maximized. The assigned channels are allocated to the respective RNs to which they have been assigned.

Abstract: In particular, systems and methods according to present principles configure physical eNodeB to have multiple virtual eNodeBs, where each virtual eNodeBs corresponds to a particular PLMN. Thus, each PLMN has its own virtual eNodeB which is hosted on a common shared physical eNodeB.

Abstract: Systems and methods are disclosed that provide a closed loop power control system including adaptively adjusting the desired target SINR over time so as to ultimately achieve a feasible SINR. In one implementation, a method is provided of optimizing uplink closed loop power control in a RAN in which one or more base stations each service a plurality of mobile stations, including: determining a power level for each mobile station for its respective uplink transmissions, including measuring a current achieved SINR for each mobile station; and for each mobile station, adjusting the power level to be sufficiently high to meet desired transmission characteristics but not so high as to cause unnecessary interference with transmissions from other mobile stations, by adjusting a desired target SINR based on factors selected from the following: current and prior achieved SINRs, current and prior interference measurements, and current and prior transmission power control commands.

Abstract: Methods and systems are provided for allocating frequencies in a radio access network (RAN) that includes a plurality of radio nodes each associated with a cell and a services node operatively coupled to the radio nodes. In accordance with the method, the radio nodes (RNs) in the RAN are divided into a plurality of clusters of RNs. A fractional frequency reuse (FFR) pattern is generated for each cluster. Transmission resources are allocated to the radio nodes in each cluster in accordance with the respective FFR pattern that is generated for each cluster.

Abstract: Arrangements disclosed here provide an LTE E-RAN employing a hierarchical architecture with a central controller controlling multiple LTE radio nodes (RNs). The RNs may be clustered within the small cell network. A fractional frequency reuse (“FFR”) scheme is provided that dynamically computes the FFR allocations at individual RNs and configures the corresponding schedulers within each RN to improve cell-edge users' experience. Once an FFR pattern has been generated and frequencies allocated, UE throughput can be emulated to predict the resulting bit rates for each UE. Using the prediction, a scheduler emulation may be run to predict the behavior of the system. The results of each cell may then be collected to generate the performance of the entire system, which may in turn be used to generate a new or modified FFR pattern, or new or modified clustering. Optimization of the performance results in an optimized FFR pattern.

Abstract: A services node or central controller or coordinator is provided that dynamically computes fractional frequency reuse allocation among user equipment in a radio access network. The central controller or coordinator communicates the fractional frequency reuse allocation and configures the individual MAC schedulers within each radio node in the radio access network. Inputs to the central coordinator may include its serving radio node, a detected set of radio nodes, and information about user equipment buffer status both in the downlink and uplink. In one implementation, interference graphs are constructed for downlinks and uplink separately and the same are used with a heuristic independent set algorithm to compute the frequency allocation.
