20150133129 | FRACTIONAL FREQUENCY REUSE SCHEMES ASSIGNED TO CLUSTERS OF RADIO NODES IN AN LTE RADIO ACCESS NETWORK - 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. | 05-14-2015 |
20150131537 | FRACTIONAL FREQUENCY REUSE SCHEMES ASSIGNED TO RADIO NODES IN AN LTE NETWORK - 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. | 05-14-2015 |
20150029944 | HYBRID JOINT PROCESSING FOR USE IN A RADIO ACCESS NETWORK - A method of joint processing of data 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 is provided. The services node provides connectivity to a core network. The method includes determining that a plurality of first UEs (User Equipment) each being serviced by a selected set of the cells is to operate in accordance with a hybrid joint processing scheme. Information is transferred between the plurality of first UEs and the radio nodes in accordance with the hybrid joint processing scheme by performing L1 layer processing on the radio nodes and L2 layer processing at the services node. | 01-29-2015 |
20140287759 | DYNAMIC PRIMARY SCRAMBLING CODE DISAMBIGUATION - Systems and methods are provided for resolving Primary Scrambling Code (PSC) ambiguity. A radio link having the same PSC as that reported by user equipment (UE) may be created on some or all internal cells which are chosen based on radio frequency (RF) proximity to a serving cell of the UE or one or more iterations of a PSC resolution set selection process. If the UE is reporting the PSC of one of these cells, the UE and a Node Bs will be able to successfully complete a synchronization procedure to add one of the radio links to the UE's active set, while any remaining created radio links can be deleted. After a certain number of successful radio link additions, the combination of the PSC and active set may be considered to be resolved, therefore, negating a need to resolve the PSC in subsequent soft handover requests. | 09-25-2014 |
20140179323 | UMTS RESELECTION PERFORMANCE IN SMALL CELL SYSTEMS - 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. | 06-26-2014 |
20130303188 | METHOD AND APPARATUS FOR LOCATION BASED SERVICES - Systems and methods for providing location estimates of user equipment to be used in location based services are provided. Data collected from users in a local radio access network (RAN), such as an Enterprise RAN (E-RAN), as well as configuration information of the local RAN/E-RAN is siphoned from the system and utilized in conjunction with a location engine to provide a high accuracy location estimate for users in an indoor environment. The siphoned data is provided in a real-time location stream to the location engine. | 11-14-2013 |
20130294403 | LONG TERM EVOLUTION ARCHITECTURE AND MOBILITY - A services node (SN) is provided that functions as a local, premise-based gateway that anchors and aggregates a group of radio nodes (RNs). Accordingly, the SN absorbs the functionalities of conventional mobility management entities (MMEs), as well as serving and packet data network gateways, where the SN appears as a single virtual eNB to a macrocellular core network. As a result, complexity associated with aggregating and controlling a large number of RNs (performed by the SN) is hidden from the core network. Additionally, micro-mobility between individual RNs controlled by an SN is completely handled at a local enterprise gateway level, thus significantly reducing mobility-related signaling from impacting an MME pool in the code network. Moreover local data offloading is made possible via the SN. | 11-07-2013 |

The initial configuration space associated with the self-configuring network is updated based on information received from the network that describes particular adequacies or inadequacies of the initial configuration space. Based on the received information, the configuration space is updated to accommodate proper and efficient operations of the network. | 10-11-2012 |
20120195256 | METHOD AND APPARATUS FOR TIMING AND/OR FREQUENCY OFFSET MONITORING AND HANDLING - Methods and apparatuses are provided for obtaining downlink or uplink signal characteristics of at least one access point in a network. The signal characteristics may be obtained through user equipment receiving the signal characteristics, through the at least one access point, or through another access point. Frequency or timing offset between two or more access points may be determined based on the obtained signal characteristics, where the frequency or timing offset may be handled through post processing. For example, a clock servo may be controlled or adjusted in response to the determined offset, the absolute frequency of a master network oscillator may be calibrated, traffic anomalies within the network may be detected and corrected, and/or respective clocks of the two or more access points may be synchronized. | 08-02-2012 |
