  • Patent number: 12010633
    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.

  • Publication number: 20240163756
    Abstract: A method and system for dynamically controlling connectivity of a user equipment device (UE) when the UE has standalone connectivity with a first access node under a first radio access technology (RAT). An example method includes the UE detecting that the UE is within threshold strong coverage of a second access node under a second RAT, and the UE making a selection between (i) responsively handing over from the first access node to the second access node and (ii) having dual-connectivity with the first access node and the second access node. Further, the example method includes the UE informing the first access node of the UE's selection, perhaps together with an inter-RAT measurement report reporting that the UE is within threshold strong coverage of the second access node, and the first access node responsively taking action in accordance with the UE's selection.

  • Patent number: 11979777
    Abstract: Systems and methods are provided for optimizing use of wireless communication technologies for a UE. The method can include determining that the UE has established a first wireless communication link to a first node that can use both a first and a second wireless communication protocol, then determining whether, prior to connecting to the first node, the UE was previously connected to a second node that only utilizes the first wireless communication protocol (e.g., standalone 5G). If the UE was previously connected to the second node and moved to the first node because of fallback or handover procedures, a second communication link is established between the UE and the second node without analyzing single information corresponding to the UE.

  • Publication number: 20240136708
    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.

  • Patent number: 11930459
    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.
