  • Publication number: 20230170961
    Abstract: Methods and systems are provided for dynamically detecting and correcting the deactivation of beamforming from an antenna. One or more users are identified as present within a particular geographic area typically served by beamforming, and the average signal strength of the one or more user devices is monitored. If a threshold level of degradation of the average signal strength is detected, then a beamforming status is determined for one or more of the antennas serving the user device or devices. Based on the determination, corrective measures are taken and beamforming is reactivated.

  • Patent number: 11290194
    Abstract: A device, method, and computer-readable medium are provided for detecting and mitigating signal interference due to passive intermodulation at a base station. Generally, when antennas are configured to transmit at two or more different bands or frequencies, particular combinations of frequencies can introduce passive intermodulation at one of the corresponding receive bands or frequencies. Passive intermodulation is exacerbated, in some instances, due to the presence of non-linearities in the RF path. Embodiments can be configured to automatically detect the presence of passive intermodulation in one of the receive bands or frequencies and dynamically mitigate the affected receive signal to maintain optimal system performance.

  • Patent number: 11190309
    Abstract: Methods and systems are provided for dynamically adjusting beamforming weights based on an azimuthal change request. A proposed azimuth change of an antenna is received, such as at a base station, where the proposed azimuth change is from remote azimuth steering of the antenna. A potential inter-cell interference is determined based on the proposed azimuth change. Based on the potential inter-cell interference, it can be predicted whether the proposed azimuth change can be made. The response, as to whether or not the proposed azimuth change can be made or not, is communicated to the base station.

  • Patent number: 10827434
    Abstract: Systems and methods for controlling coverage in a wireless communications network after a disruption in a control signal provided to a multi-directional antenna are provided. The system may detect that a disruption has occurred in the control signal, causing the antenna to broadcast in a different mode and leading to a change in the coverage area. The change in the coverage area may cause user devices to experience a drop in coverage or to experience interference from multiple, overlapping coverage areas. In embodiments, the system increases or decreases the power provided to the antenna to control the coverage area and/or limit interference, in order to compensate for the disruption.

  • Patent number: 10660095
    Abstract: A base station dynamically controls whether or not to serve a WCD on an in-band carrier defined within occupied bandwidth of a host carrier, with the dynamic controlling being based on whether the base station is operating in a capacity-mode on the host carrier, such as whether the base station has beamforming enabled on the host carrier and/or the base station is serving one or more relay nodes on the host carrier. If the base station is operating in a capacity-mode on the host carrier, then the base station could responsively transition a WCD from being served on the in-band carrier to instead being served on a guard-band carrier defined within a guard-band of the host carrier, or to being served on another carrier that is not an in-band carrier defined in the occupied bandwidth of the host carrier.

  • Patent number: 10470055
    Abstract: Embodiments of the invention include a system for reducing tropospheric ducting and tropospheric refraction in a wireless telecommunication network. A base station or network component receives weather information and determines if conditions are right for tropospheric ducting or tropospheric refraction. A simultaneous rise in UL interference, call failure rates, and call drop rates in adjacent markets can indicate tropospheric ducting. A rise in UL interference, call failure rates, and call drop rates by devices in one market can indicate tropospheric refraction. Where these UL interferences, call failure rates, and call drop rates occur daily for a similar duration each day, they are treated as being caused by tropospheric propagation and a mitigation routine is implemented through antenna down-tilt.

  • Patent number: 10411781
    Abstract: Methods and systems are provided for dynamically adjusting vertical beamforming weights to influence a width of a vertical beam emitted from an antenna. A quantity of users present in a particular geographic area is determined, where the user devices have a line of sight with the antenna and are vertically distributed from other user devices. CQIs are received from the user devices. It is determined that the quantity of user devices is above a maximum threshold of user devices, and the CQIs indicated that channel quality is below a minimum threshold. The amplitude and phase components of the vertical beamforming weight are adjusted to modify the width of the vertical beam emitted from the antenna.

  • Patent number: 10355752
    Abstract: Systems and methods for providing configured and/or dynamically adjustable coverage in wireless communications networks is disclosed. A broadcast cell may include one or more antennas used to provide one or more sectors of coverage in the network. Each antenna may include at least one radio and at least one corresponding signal transmitting and receiving component that is in communication with the radio, allowing a signal generated by the radio to be broadcast by the signal transmitting and receiving component to form at least a portion of a sector of coverage provided by the antenna. Additionally, the signal generated by the radio may be modifiable, allowing the beam of coverage emitted by the signal transmitting and receiving component to be adjusted (e.g., in any one of an x, y, and/or z-plane) for a particular operating environment.

  • Patent number: 10314055
    Abstract: System, methods, and computer-readable media herein dynamically assign bands to primary and secondary component carriers for inter-carrier aggregation capable devices. In embodiments, an inter-carrier aggregation capable device is identified as being within a coverage area of a cell site component that is controlled by a base station. When the device is within a predefined distance of the cell site component, throughput of the device is analyzed. When the throughput indicates that the device is impacted by noise and/or interference at the cell site, the base station assigns a band to a primary component carrier based on the sector power ratio (SPR) of a corresponding antenna.

  • Patent number: 10187895
    Abstract: A method and system to help control air interface resource allocation. A base station monitors for each served UE a ratio of physical resource block (PRB) allocation to queued data, as a PRB/data ratio. The base station then detects that the PRB/data ratio of a first served UE has been threshold lower than the PRB/data ratio of each of a plurality of second served UEs, and the base station responsively selects at least one of the second UEs based on its modulation and coding scheme (MCS) being relatively high, and the base station limits PRB allocation to the selected UE to help reduce its PRB/data ratio and to thereby help achieve a level of fairness in PRB allocation.

  • Patent number: 10171282
    Abstract: Dynamic amplitude modulation in a telecommunications network in response to user reported performance indicators is described. The performance indicators may be associated with at least one user device and/or at least one antenna. For example, the performance indicators may include reference signal received power (RSRP), antenna gain, and/or insertion loss (IL). The performance indicators may trigger generation of new amplitude weights or values and application of the new amplitude weights or values to the telecommunications network.
