| 20120009964 | 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 customer premise equipment (CPE) uses a plurality of bits to quantize the phase angle of the beamformed data received by CPE and reports it to its serving base station. The serving base station selects one of the phase adjustment angles based on the bits received from the CPE in order to schedule the data transmission to the CPE. The phase adjustment angles are in “n” degree steps. | 01-12-2012 |
| 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 |

| 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 |
| 20100216485 | SYSTEMS AND METHODS FOR USAGE-BASED OUTPUT POWER LEVEL ADJUSTMENTS FOR SELF-OPTIMIZING RADIO ACCESS NODES - A wireless base station and method are described for adjusting an output power level for self-optimizing radio access node. The base station monitors a link metric of a downlink traffic channel and records the measurements as historical link metric data.

When voice data and traffic data are sent simultaneously in a wireless network using a limited set of frequency resources, the data traffic can cause unacceptable interference in the voice traffic. Accordingly, transceivers share their voice traffic and data traffic demands and may allocate portions of an airlink resource into resource zones for exclusive use by voice traffic and data traffic. Within each resource zone, the transmission can be optimally managed for each traffic type, and interference between voice traffic and data traffic is reduced. | 08-26-2010 |

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 are 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 |
| 20100216477 | SYSTEMS AND METHODS FOR USAGE-BASED RADIO RESOURCE MANAGEMENT OF SELF-OPTIMIZING CELLS - Systems and methods are described for allocating frequency resources based on historical usage data in a wireless communication system.

The server may generate a frequency resource allocation plan to allocate shared resources most efficiently to various base stations based on historical usage information. Allocating frequency resources in this manner reduces the probability of cochannel interference between nearby cells and optimizes power solutions for local and regional radio access networks. | 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 |
