Abstract: A beacon cell adapted for use in a small cell RAN includes dual identities—a beacon identity and a regular or “live” identity—in which the identities are individually configured to address differing performance requirements in the small cell RAN. The beacon identity in the cell is specially configured to meet the performance requirements for mobile user equipment (UE) to be able to quickly and easily move from a macrocell base station in a mobile operator's network to the small cell RAN using a process called “reselection.” The live identity is configured to meet all requirements for service to be provided to the UE within the small cell RAN. Once captured by the beacon identity of the beacon cell, the UE can then immediately reselect to the live identity of the cell which operates in a conventional manner.

Abstract: A method for assigning downlink transmit power levels to radio nodes (RNs) in a small cell radio access network (RAN) includes assigning initial power levels to the RNs. For each cell, first events are counted indicating that UEs receiving a signal from their serving cells with a signal strength below a specified value have entered a coverage hole. For each cell, second events are counted indicating that UEs have re-established a previous connection on one of the cells. For each pair of cells, a coverage hole is identified between them if the number of first events for one cell exceeds a threshold and a number of second events or re-establishment of a previous connection on the other cell exceeds another threshold. For each identified coverage hole, the downlink transmit power level is increased of at least one RN in the pair of cells between which the coverage hole is identified.

Abstract: A method for assessing an impact of a design choice on a system level performance metric of a radio access network (RAN) deployed in an environment includes receiving messages from a plurality of UEs over time by a plurality of RNs in the RAN. A design choice is selected for a set of operating parameters of the RAN. One or more of measurement values in each of the received messages and the selected design choice are processed to compute a set of derivatives. A system level performance metric is determined as a function of the computed set of derivatives.

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: 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: 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: In accordance with a method for communicating over a channel in a frequency band (e.g., an unlicensed frequency band) shared by different radio access technologies, prior to transmitting a signal beginning at a predetermined time on a first channel in a frequency band in accordance with a first radio access technology (RAT), the first channel is sensed to determine if it is unoccupied during a specified first duration of time for a specified second duration of time. If the first channel is unoccupied for the specified second duration of time, a channel reservation signal is immediately transmitted on the first channel. The channel reservation signal is decodable by a node operating in accordance with a second RAT different from the first RAT.

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.
