  • Patent number: 11575422
    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.

  • Publication number: 20230026417
    Abstract: A wireless UE wirelessly attaches to a network controller over a source RAN. The UE transfers UE capabilities that comprise a Public Land Mobile Network Identifier (PLMN ID) and transfers a slice request for a network slice type to the network controller over the source RAN. The network controller selects a network slice based on the requested network slice type. The network controller selects a mobility profile that comprises handover criteria based on the requested slice type and the PLMN ID. The UE exchanges user data with a user plane over the selected network slice. The UE determines a handover requirement based on the handover criteria and identifies a set of target RANs. The UE selects one of the target RANs based on the handover criteria and hands over to the target RAN. The UE exchanges additional user data with user plane over the network slice and the target RAN.

  • Patent number: 11563466
    Abstract: Methods, media, and systems are provided for restricting an uplink Multiple Input Multiple Output (MIMO) assignment based on fading, battery data, or location data associated with a user device in an mmWave system. Fading data, location data, or battery data is received from one or more user devices. Based on the received data, a determination is made using the data received (e.g., determining the battery data of the user device is below a threshold or determining the location of the user device). In response, the assignment of the user device to an uplink MIMO layer of available MIMO layers is restricted. The restricted uplink MIMO layer is a higher MIMO layer than another MIMO layer of the available MIMO layers. In response to restricting the assignment, the user device may be assigned to an available MIMO layer that is a lower MIMO layer than the restricted MIMO layer.

  • Publication number: 20230016918
    Abstract: A method and system to dynamically reassign RF spectrum from a first access node to a second access node, where the first access node provides service on a first carrier having a carrier bandwidth. An example method includes (i) selecting a frequency portion of the carrier bandwidth to reassign, the selecting being based on the frequency portion having higher determined noise than one or more other frequency portions of the carrier bandwidth, and (ii) based on the selecting, reassigning the selected frequency portion from the first access node to the second access node to be used by the second access node as at least part of a second carrier on which to provide service. Upon reassigning of the selected frequency portion, the second access node could then provide service on the reassigned portion and the first access node could continue to provide service on a remainder of the first carrier.

  • Publication number: 20230018640
    Abstract: Methods and systems are provided for using antenna sector power ratio (SPR) to determine dynamic spectrum sharing. Frequency bands associated with a cell site can support at least one wireless communication protocol. In some embodiments, a plurality of frequency bands for a plurality of cell sites are identified. SPR values for each frequency band may be determined, and a frequency band having the lowest SPR value may be identified. For example, a frequency band having a lower SPR value that is also below a particular threshold may be assigned a wireless communication protocol that was previously assigned to another frequency band having a higher SPR value. Based on assigning the frequency band another wireless communication protocol, a user device may be provided resources via that wireless communication protocol.

  • Patent number: 11558920
    Abstract: A wireless User Equipment (UE) controls a wireless network slice type that has slice requirements. In the UE, source Radio Resource Control (RRC) circuitry exchanges source signaling with a source Access and Mobility Management Function (AMF). During the exchange of the source signaling, target RRC circuitry exchanges target signaling with target AMFs and determines AMF characteristics. The target RRC circuitry compares the AMF characteristics to the slice requirements and selects one of the target AMFs based on the comparison. The source or target RRC circuitry exchange additional target signaling with the selected one of the target AMFs to use the wireless network slice type. User-plane circuitry exchanges user data with the wireless network slice which is controlled by the selected target AMF.

  • Patent number: 11540180
    Abstract: When an access node is providing a UE with carrier-aggregation service on a PCell in combination with one or more SCells and the UE engages in a voice call including uplink voice communication on the PCell, the access node will determine that there is a threshold high level of IMD on the uplink resulting from concurrent downlink transmissions, and the access node will responsively swap the UE's PCell with one of the UE's one or more SCells. In a representative implementation, the decision to swap these carriers in the UE's connection could be based on a further determination that the level of IMD on the uplink of the SCell is not threshold high.

  • Patent number: 11532880
    Abstract: Systems, methods, and computer-readable media herein dynamically adjust the number of elements active within a neighboring base station in order to reduce the back lobe overlap and thus reduce the interference caused by such an overlap. User devices assigned to communicate with an antenna array are monitored to determine if they are experiencing a decreased level of performance which may be caused by an overlapping back lobe from a neighboring cell site. If the user device's performance falls below a threshold value, the gain associated with the neighboring cell site is dynamically reduced in order to reduce the back lobe overlap.
