| 20080212501 | Half Duplex Frequency Division Duplex Scheduling - A method, computer program, and a wireless system for scheduling half duplex frequency division duplex bursts includes populating a burst frame having an uplink sub-frame and a downlink sub-frame with one or more block pairs, each block pair including an uplink block and a down link block. Populating the burst frame includes identifying a largest unscheduled block pair, and appending one of the uplink block and the downlink block of the identified block pair to a shortest sub-frame string. Populating the burst frame also includes appending the other of the uplink block and the downlink block to a diagonally opposed sub-frame string. The method also includes determining if a conflict exists between the uplink block and the downlink block for each scheduled block pair. | 09-04-2008 |
| 20100214925 | SYSTEMS AND METHODS FOR HYBRID RATE-LIMITING SCHEMES BASED ON PROTOCOL DATA UNIT CHARACTERISTICS - A networked computing system that utilizes a hybrid rate-limiting scheme to jointly affect both PDU payload throughput and total PDU throughput. The networked computing system includes one or more service provider devices (SPDs), one or more subscriber computing devices (SCDs), and a data communications network facilitating data communications between a SPD and a SCD. The SPD can apply the hybrid rate-limiting scheme to data communications provided to the SCD, based on both protocol data unit (PDU) header and payload characteristics. The hybrid rate-limiting scheme can simultaneously facilitate rate-limiting PDU payload throughput and rate-limiting total PDU throughput. | 08-26-2010 |
| 20100216407 | SYSTEMS AND METHODS FOR DYNAMIC TEMPERATURE CALIBRATION OF A FREQUENCY REFERENCE - A system and method are described for dynamic temperature calibration of a frequency reference in a wireless base station. In a consumer grade base station, a reference oscillator may encounter frequency drift as the temperature of the base station changes. This causes interference as the transmission signal is not synchronized with other frequency resources in a network. An improved method of calibrating a reference frequency includes measuring a frequency difference between a frequency derived from an accurate reference frequency in a first base station and a frequency derived from a less accurate frequency reference in a second base station, determining a calibration factor for the offset, and applying the calibration factor to the base station to correct frequency drift. The calibration factors may be correlated with an operating temperature of the base station and stored in a temperature calibration table in the base station device. | 08-26-2010 |
| 20100216452 | SYSTEMS AND METHODS FOR BASE STATION REFERENCE FREQUENCY CORRECTION AND TIMING CORRECTION USING TRANSCEIVER FEEDBACK - A wireless communications system includes a radio resource manager, one or more base stations, and one or more wireless transceivers capable of communicating with the base stations. The wireless transceivers are configured to be able to measure the difference in network parameter (e.g. frequency and timing offset) between base stations within their range. These network parameter differences along with other information is communicated to the radio resource manager which is then able to update or correct the signal or signals of one or more base stations using the information from the wireless transceivers. | 08-26-2010 |

| 20100246391 | SYSTEMS AND METHODS FOR REDUCING CONGESTION IN A WIRELESS NETWORK - A system and method are described for reducing congestion in a wireless network. A wireless base station becomes congested when substantially all of the available base station airlink resources are being used during a period of time. It is useful, however, to distinguish between periods of congestion with few users and periods where a larger number of users are using the base station. When there are few users a congestion situation is not necessarily a problem, while it is more likely that users' quality of experience and quality of service suffers as the number of users increases. This system and method determines when a base station is congested and implements a congestion prime management scenario when the number of active users is above an activity threshold. | 09-30-2010 |
| 20100260044 | SYSTEMS AND METHODS FOR HYBRID RATE LIMITING BASED ON DATA BIT COUNT AND DATA PACKET COUNT - A networked computing system employing a hybrid rate-limiting scheme, including one or more service provider device(s) (SPD) and one or more subscriber computing device(s) (SCD), and a data communications network facilitating data communications amongst the networked SPD and SCD devices. A SPD may apply the hybrid rate-limiting scheme to data communications provided to a SCD, based on both data bit count and data packet count information. The rate-limiting scheme may include a dual token bucket algorithm that facilitates rate-limiting PDUs in a data transfer queue utilizing one token bucket for metering data bits and another token bucket for metering data packets. The hybrid rate-limiting scheme may also employ a triple token bucket algorithm that includes one token bucket for metering data bits related to payload only data, a separate token bucket for metering data bits related to total PDU data, and another token bucket for metering data packets. | 10-14-2010 |
| 20110268217 | SYSTEMS AND METHODS FOR COORDINATING THE SCHEDULING OF BEAMFORMED DATA TO REDUCE INTERFERENCE - A system and method are disclosed for coordinating the scheduling of beamformed data to reduce interference in a wireless system. A first optimum phase adjustment is determined to increase the gain of an intended signal at a mobile device. A second optimum phase adjustment is determined to decrease the gain of interfering signals received at the mobile device. Using a phase adjustment map, a transmission is scheduled at a base station within wireless resources using the first optimum phase adjustment, at the same time an interfering base station is transmitting at the second optimum phase adjustment angle. Thus, signal strength is greatly improved while interference is greatly reduced, improving the efficiency of the wireless system. | 11-03-2011 |
