摘要： Apparatus and methods for synchronizing a network element (e.g. access points, femtocells, etc.) to a master network (such as a cellular network) to provide accurate frequency and/or time references for their internal systems. In one embodiment, the network element utilizes a dedicated receiver (or transceiver) to receive timing information from the master network. The implementation of the dedicated receiver is advantageous for cost and simplicity reasons. Furthermore, the timing or frequency information, as received from the master network, is used to correct the network element's internal timing. In addition, the network element's internal timing can operate in open-loop mode, if no master network can be found, thereby allowing for the device to continue providing service to network users. Additionally, a dedicated receiver can also receive information (e.g. location, SID, NID, SSID, etc.) local to the network element, such information may be useful or required for seamless operation within the master network.

摘要： In wireless system, a group of Base station (BTSs) with smaller footprints have the capability to communicate with each other as well as with the BTSs with relatively larger footprints via wireless air-interfaces. One of such example is coordinated cell systems. A coordinated cell system comprises a group of coordinated cell base stations that have the capability to communicate with each other as well as with relevant macro cell or Pico cell base stations via wireless air-interfaces. Each coordinated cell BTS consists of an over the air control unit in addition to the conventional coordinated cell BTS system. A set of protocols in the form of messages and database are also defined to enable the networking capability. This enables enhancement in performing a variety of tasks by coordinated cell systems, including interference management and coordination, registration and authentication, quality of service coordination, installation and maintenance, location services, etc.

摘要： Methods, apparatus, and systems for dynamic antenna tilt coordination. In one embodiment, real-time data from user equipment (UE) measurement reports are aggregated across multiple base station entities. State input for a machine learning algorithm may be generated from the aggregated UE measurements. The machine learning algorithm may be trained to maximize a real-time network consideration (such as data throughput) by adjusting antenna tilt. During operation, the machine learning algorithm provides tilt settings to each of the radio units (RU) of a base station. Live feedback allows the machine learning algorithm to robustly handle a variety of conditions (e.g., weather, data traffic, etc.)

摘要： A self-organizing wireless network (SON) includes a plurality of base stations. Each base station includes a SON component for coordinating radio resource allocation with other base stations and a radio resource management component for accepting an allocation from the SON component and managing usage of that allocation for end user equipment associated with its base station. The base stations provide access to a plurality of end user equipment. The SON may include a server for communicating with the SON component for coordinating of radio resource allocation. The self-organizing wireless network may include a central control for communicating with the SON component for coordinating of radio resource allocation. Coordinating of radio resources relates to physical channels, transmit power, spatial resource allocation, admission control, load balancing, coordinating network elements in groups and includes adapting to addition of and reduction of network elements in a group in real time.

摘要： A method and system architecture for a self-organizing network (SON) includes a first cell having a first user equipment classifier for determining one of cell edge and cell central. The SON also includes a second cell having a second user equipment classifier for determining one of cell edge and cell central. The system architecture and method provide a first transmit time interval (TTI) schema for user equipment within the area of coverage associated with the first cell and a TTI schema for user equipment within the area of coverage associated with the second cell, the second TTI schema differing from the first TTI schema. The user equipment is classified as cell center or cell edge in dependence upon at least one of QoS requirement, geometry, periodic PSMM and CQI reports. The TTI schemas are used for “cell edge” user equipment by the respective cells.
