  • Patent number: 11671820
    Abstract: A wireless access node control Multiple Input Multiple Output (MIMO) layers for a User Equipment (UE). A radio wirelessly exchanges network signaling with the User Equipment (UE) and exchanges the network signaling with baseband circuitry. The baseband circuitry exchanges the network signaling with the radio. The baseband circuitry determines a UE capability and identifies radio band status for the UE. The baseband circuitry selects a number of the MIMO layers for the UE based on the UE capability and the radio band status. The baseband circuitry precodes user data into precoded data for the selected number of MIMO layers and transfers the precoded data to the radio. The radio receives the precoded data from the baseband circuitry and wirelessly transmits the precoded data to the UE over the selected number of MIMO layers.

  • Patent number: 11665764
    Abstract: Systems and methods are provided for dynamically determining optimal 5G New Radio (NR) configuration for dual Radio Access Technology (RAT) technology capable user equipment (UE). After receiving an indication a UE has connected to a particular sector, an eNodeB having a nonstandalone (NSA) 5G node and a standalone (SA) 5G node requests historical information or geotagged data corresponding to the UE. The eNodeB determines a NSA signal quality for a 5G node of the eNodeB and a SA signal quality of the 5G SA node. Based on a delta of the NSA signal quality and the SA signal quality being below a predetermined threshold, the eNodeB uses the historical information or the geotagged data to dynamically assign the UE to the NSA 5G node or the SA 5G node.

  • Publication number: 20230141889
    Abstract: Methods and systems are provided for dynamically disabling beamforming functionality of one or more frequency bands. For example, a frequency band may have beamforming enabled. One or more user devices may be connected to the frequency band having beamforming enabled for access to a wireless telecommunications network. User devices connected with the frequency band may be at various locations of a network cell of the wireless telecommunications network (e.g., a cell center, middle cell, cell edge). Fading information may be received by one or more of the user devices connected with the frequency band. One or more fading channel measurements of the first frequency band may be above a threshold. In some embodiments, a fading channel measurement of the first frequency band is higher than another available frequency band having beamforming enabled. As such, beamforming of the first frequency band can be dynamically disabled.

  • Publication number: 20230137792
    Abstract: Systems and methods are provided for dynamically modifying beamforming weights based on MU-MIMO user device pairings. A quantity of MU-MIMO user device pairings served by a node is determined. Based on a maximum quantity of potential MU-MIMO user device pairings for the node, it is determined that a quantity of the MU-MIMO user device pairings for the node is below a threshold. Because the quantity of the MU-MIMO user device pairings is below the threshold, beamforming weights are modified to widen a vertical main lobe to increase the quantity of MU-MIMO user device pairings.

  • Publication number: 20230119265
    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.
