  • Publication number: 20200374770
    Abstract: Beamforming techniques can improve base station transmission power and user equipment (UE) sensitivity reception. For example, beamforming can create a narrow beam, which can concentrate signal power in a much smaller region. Combined with base station (gNB) requests and UE location data, an accurate beam can be generated to cover a desired area. 5G base station broadcasts can utilize a globally unique cell identifier (e.g., physical cell identifier), and a locally unique cell identifier (e.g., new radio cell global identifier) to facilitate beamforming and mitigate handover failure.

  • Patent number: 10750437
    Abstract: A method and system for proactively managing a base station neighbor list. A base station or other network node tracks changes to the base station's neighbor list and identifies a recurring pattern of changes, in correspondence with a particular time of day for instance. The base station or other node then proactively changes the base station's neighbor list in anticipation of a recurrence of the identified pattern, such as in anticipation of recurrence of the time of day for instance. Advantageously, this method can help to reduce the extent to which the base station engages in an automatic neighbor relation process, and thus reduce the extent of signaling and other issues associated with engaging in that process.

  • Patent number: 10531315
    Abstract: In modern networks, frequent handovers (e.g., ping-pong) from one AP device to another is a situation that can lead to increased latency, excessive resource utilization, poor quality of service, or radio link failure (RLF). Conventional networks employ mobility robustness optimization (MRO) procedures to balance tradeoffs between setting low thresholds before initiating a handover procedure, thereby increasing the likelihood of ping-pong issues, and setting those thresholds to higher values, thereby increasing the likelihood of RLF. Conventional MRO procedures are tailored to terrestrial-only networks and furthermore merely react to existing issues. Hybrid networks, having both terrestrial and aerial AP devices often witness ping-pong issues and may be implemented with urgency not conducive to using MRO procedures. An architecture is presented that can predict and mitigate ping-pong and other issues in connection with hybrid networks before those issues occur.

  • Patent number: 10470116
    Abstract: Systems and methods are described for determining an access node for a wireless device. A first signal may be transmitted from a first access node with an increased signal level. An indication of a first adjustment factor based on the increased first signal level may also be transmitted from the first access node. Signal information may then be received from a wireless device, where the signal information includes a determined first signal level associated with the first access node and a determined second signal level associated with a second access node. The determined first signal level from the signal information may comprise a received signal level of the first signal decreased by the first adjustment factor. Based on the signal information, one of the first access node and the second access node may be selected for communication with the wireless device and the wireless device may be instructed to communicate with the selected access node.

  • Patent number: 10278124
    Abstract: Methods and systems are provided for calculating a bias value based on radio frequency signal power measurements. A wireless communication device (WCD) measures the powers of radio frequency signals received by the WCD, including a first radio frequency signal transmitted by a first base station of a wireless network and a second radio frequency signal transmitted by a second base station of the wireless network. The first base station transmits radio frequency signals at a higher power than the second base station. The WCD calculates a bias value based on at least one of the measured powers of the first radio frequency signal and the second radio frequency signal. The bias value, in combination with the measured powers of the first and second radio frequency signals, can be used to select one of the first and second base stations.

  • Patent number: 10009915
    Abstract: Systems and methods are described for cross scheduling transmissions from an access node. Data may be communicated between an access node and a wireless device over a first frequency band. A first application and a second application associated with the wireless device may be determined, where each of the applications comprises an application type. Based on the application type one of the first frequency band and a second frequency band may be selected for the first application and the second application, where the selected frequency bands are different. Transmissions associated with the first application may then be scheduled over the frequency band selected for the first application and transmissions associated with the second application may then be scheduled over the frequency band selected for the second application.

  • Patent number: 9923836
    Abstract: Systems and methods are described for configuring a delay based scheduler for an access node. A plurality of packets may be received at an access node, where at least a first packet is associated with an application running on a wireless device in communication with the access node. The plurality of packets may be inspected to determine that one or more of the packets associated with the application are marked, where the mark indicates network congestion. A remaining time for the first packet may be calculated based on a packet delay budget associated with the running application and the determination that one or more of the packets associated with the application are marked. The first packet may then be scheduled for transmission to the wireless device, using a delay based scheduler, based on the calculated remaining time.

  • Patent number: 9918282
    Abstract: Systems and methods are described for determining a power option for an access node. Application requirements for a first plurality of wireless devices in communication with a first access node may be identified for each wireless device. The number of wireless devices that comprise a met application requirement may then be determined. When that number meets a first criteria, a plurality of power options for transmitting a first signal may be determined. For each power option, a second number of the first plurality of wireless devices and a third number of wireless devices in communication with a second access node may be estimated. Based on the estimated numbers for the determined power options, a power option may be selected and the first access node may transmit the first signal according to the selected power option.
