  • Publication number: 20220295362
    Abstract: Methods are provided for dynamically deactivating synchronization signal block (SSB) beams based on uplink noise. Uplink noise is monitored at a cell site over a configurable period of time. Upon the uplink noise being determined to be above a threshold value, SSB beams corresponding to user equipment that are contributing to the uplink noise are determined. Based on a magnitude of the uplink noise at the cell site, one or more SSB beams of the SSB beams are dynamically deactivated at the cell site.

  • Patent number: 11445421
    Abstract: A wireless communication network to serve a wireless User Equipment (UE) with a wireless communication service over multiple wireless communication links. The wireless communication network comprises a primary access node, a first support access node, and a second support access node. The primary access node receives signal metrics for the support access nodes from the wireless UE, determines add thresholds for the support access nodes based on the amount of active UEs served by the primary access node, and converts the signal metrics for the support access nodes into add values for the support access nodes. When the add values are greater than the add thresholds, the primary access node signals the corresponding ones of the support access nodes to serve the wireless UE. The corresponding ones of the support access nodes exchange user data with the wireless UE.

  • Patent number: 11445571
    Abstract: A Radio Access Network (RAN) is configured to serve wireless User Equipment (UEs). The RAN comprises a Baseband Unit (BBU) and a Tower Mounted Amplifier (TMA). The BBU determines an amount of proximate wireless UEs that have transmit power levels that fall below a proximity threshold and when the amount of the proximate UEs exceeds a concentration threshold. When the proximate UEs exceeds the concentration threshold, the BBU schedules the proximate wireless UEs to use proximate UE Transmit Time Intervals (TTIs) and schedules other wireless UEs to use other TTIs. The BBU transfers control signals to deactivate TMA amplification during the proximate UE TTIs and to activate the TMA amplification during the other TTIs. The TMA receives UE signals, and in response to the control signals, deactivates TMA amplification on UE signals during the proximate UE TTIs and activates TMA amplification on UE signals during the other TTIs.

  • Patent number: 11445402
    Abstract: In a wireless communication network, a wireless network core and wireless access nodes exchange user data using data rates. The wireless access nodes wirelessly exchange the data with the wireless UE over radio bands. The wireless network core determines a data rate level for the wireless UE based on the data rates. Subsequently, the wireless network core identifies a serving wireless access node and a serving radio band. The wireless network core determines a new data rate based on the data rate level and the serving radio band. The wireless network core and the serving wireless access node exchange new data using the new data rate. The serving wireless access node wirelessly exchanges the new data with the wireless UE over the serving radio band.

  • Patent number: 11445426
    Abstract: Systems and methods are provided for setting handover thresholds and dynamically initiating handovers based on antenna parameters and wireless device location. A processor identifies an antenna having a sector power ratio exceeding a predefined threshold. Undesirable locations for wireless devices relative to the antenna are determined based on stored information and a first handover threshold is set for wireless devices served by the antenna and in undesirable locations. When a wireless device is found in the undesired location and the sector power ratio exceeds the predefined threshold, the first handover threshold is met. A handover may be initiated.

  • Patent number: 11432183
    Abstract: A method and system to control carrier aggregation in a wireless communication system including a first access node and a second access node, where the first access node has a first respective backhaul connection, where the second access node has a second respective backhaul connection, where the first access node supports serving user equipment devices (UEs) with standalone connectivity, and where the first and second access nodes cooperatively support serving UEs with dual connectivity. A method includes detecting that the second respective backhaul connection of the second access node is threshold heavily loaded. And the method includes, based at least in part on the detecting that the second respective backhaul connection of the second access node is threshold heavily loaded, causing the first access node to suppress an extent of carrier-aggregation service that the first access node will provide to any standalone-connected UEs, to help free up capacity for dual-connectivity service.

  • Patent number: 11425770
    Abstract: A method and system for controlling dual-connectivity service in a system where a first access node provides service on a first air interface and a second access node provides service on a second air interface, and where (i) in a single-connection-uplink mode for the dual-connectivity service, uplink user-plane communication is carried on just the second air interface and (ii) in a split-uplink mode for the dual-connectivity service, uplink user-plane communication is split between the first air interface and the second air interface. An example method includes determining an uplink Multi-User Multiple-Input-Multiple-Output (MU-MIMO) grouping efficiency of the second air interface and, based on the determined uplink MU-MIMO grouping efficiency of the second air interface, controlling whether to provide the dual-connectivity service in the single-connection-uplink mode or rather in the split-uplink mode.
