摘要： A system and method for adaptive control of an averaging parameter in a communications network may include an averaging parameter adaptive control module (APAC) that is associated with a base station and that includes one or more processors configured to generate a first averaging parameter that is transmitted by the base station to a mobile station communicating with the base station. The mobile station may use the first averaging parameter to generate first channel condition information that indicates a condition of a communication channel. First feedback information including the first channel condition information may be received at the base station. The APAC may generate a second averaging parameter using the first averaging parameter and the first feedback information and may transmit the second averaging parameter from the base station to the mobile station, thereby adaptively controlling the second averaging parameter based on the first feedback information.

摘要： Exemplary methods and systems may generally be implemented to allow a macro-network base station without access to a GPS reference signal to provide some or all of the functionality for which existing macro-network base stations typically rely on GPS. In a first aspect, an exemplary macro-network base station may determine its location using a location-determination technique that is based upon the angles of arrival of FM radio signals from nearby FM stations. In a second aspect, an exemplary macro-network base station may stabilize its local oscillator by phase-locking its local oscillator to an FM radio signal, and periodically adjusting its local oscillator to account for phase drift of the FM radio signal. And in a third aspect, an exemplary macro-network base station may synchronize its frame-start timing with a nearby base station using a frame-start timing signal that the base station has synchronized to frame transmissions from the nearby base station during a setup routine.

摘要： In various embodiments, a method, computer-readable storage medium, and apparatus for scheduling prioritized best effort (BE) service flows through a wireless network base station includes a controller coupled to a memory. If any one of a plurality of BE service flows are congested, a minimum reserved traffic rate (MRTR) algorithm is used by the controller to ensure that at least a highest priority BE service flow is maintained at least at an associated MRTR. If none of the plurality of BE service flows are congested, a maximum sustained traffic rate (MSTR) algorithm is used by the controller to enable the highest priority BE service flow to be set to at least at an associated MSTR before lower priority service flows are increased. If none of the plurality of BE service flows are congested and each service flow is at their associated MSTR, the controller is configured to distribute any excess bandwidth to each service flow in accordance with an initial set of priority BE traffic flow ratios.

摘要： Systems and methods for detecting and mitigating interference between from a wireless time division duplex (TDD) communications device and a wireless frequency division duplex (FDD) communications device includes processing quality-indicator reports received from the FDD device to determine if the FDD device has experienced interference from the TDD device. Such interference may be mitigated by adjusting a downlink configuration of the FDD base station in communication with the FDD device. To detect and mitigate interference from an FDD device to a TDD device, it is determined if a monitored value of an operational parameter of the FDD device is within a fixed range of a maximum value of the operational parameter, and if so, a specific time interval or frequency of the FDD device is assigned for communication purposes. Similar interference detection and mitigation techniques may also be used for interference scenarios between two TDD systems including TDD devices.

摘要： A method of operating a communication system comprises exchanging initial communications between a wireless communication device and a communication network over a wireless connection between the wireless communication device and a network access system and a network connection between the wireless communication device and the communication network. The method further comprises performing a plurality of ranging processes to monitor a status of the wireless connection. Upon successfully completing a ranging process of the plurality of ranging processes, the method comprises determining a duration elapsed since the last successful ranging process and processing the duration to determine if the duration satisfies a criteria. The method further comprises, if the duration does not satisfy the criteria, then setting the indicator to indicate that a partial entry process is required to regain the network connection, and in response to the deterioration of the wireless link, processing the indicator to determine if the partial network entry process is required to regain the network connection.
