  • Publication number: 20240107377
    Abstract: A method and system for controlling data split of a dual-connected user equipment device (UE) when the UE has at least two co-existing air-interface connections including a first air-interface connection with a first access node and a second air-interface connection with a second access node. An example method includes (i) comparing a level of spectral efficiency of the first air-interface connection with a level of spectral efficiency of the second air-interface connection, (ii) based at least on the comparing, establishing a split ratio that defines a distribution of data flow of the UE between at least the first air-interface connection and the second air-interface connection, and (iii) based on the establishing, causing the established split ratio to be applied. Further the method could include using the comparison as a basis to set one of the UE's air-interface connections as the UE's primary uplink path.

  • 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.

  • Publication number: 20240080682
    Abstract: Systems and methods are provided for dynamically modifying an antenna profile to increase network performance. Initially, it is determined that one or more user devices communicating using at least a first wireless communication protocol and operating using uplink split mode are connected to a sector. Performance of a plurality of other user devices communicating using a second wireless communication protocol and connected to the sector are monitored. Upon determining that the performance of at least one user device of the plurality of other user devices is below a threshold, the antenna profile is dynamically adjusted to narrow a beam associated with the first wireless communication protocol such that at least one or more user devices capable of communicating using at least the first wireless communication protocol is unable to communicate using the first wireless communication protocol.

  • Patent number: 11924777
    Abstract: Dynamically limiting uplink transmit power of wireless devices that are known to be within range of a dense cluster or quantity of access nodes.

  • Patent number: 11917672
    Abstract: A wireless user device wirelessly receives an indication of selected resource blocks in a frequency channel that are selected for radio signal measurement and unselected resource blocks in the frequency channel that are unselected for the radio signal measurement. The wireless user device wirelessly measures a radio signal metric for the selected resource blocks in the radio channel and does not measure the radio signal metric for the unselected resource blocks in the radio channel. The wireless user device wirelessly transfers the radio signal metric for the selected resource blocks in the radio channel. The wireless user device wirelessly receives a schedule for the selected resource blocks in the radio channel. The wireless user device wirelessly receives data over the selected resource blocks in the radio channel based on the schedule.

  • Patent number: 11910253
    Abstract: When a first radio of a UE has an air-interface connection with an access node on a first carrier and the UE encounters a trigger for the UE to scan for and report to the access node coverage on a second carrier, a second radio of the UE, rather than the first radio of the UE, will conduct the scanning, and the first radio of the UE will then report to access node over the air-interface connection on the first carrier a result of the scanning conducted by the second radio. Optimally, the first radio of the UE thus need not tune away from its air-interface connection with the access node in order for the UE to scan for target coverage on the second carrier. And the process could thereby help avoid the interruption of communication between the UE and the access node on the air-interface connection over the first carrier.

  • Patent number: 11901645
    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: 11889543
    Abstract: A wireless access node serves wireless User Equipment (UE) over radio frequency bands. In the wireless access node, radio circuitry wirelessly receives signaling from the wireless UE that indicates received signal strengths and Multiple Input Multiple Output (MIMO) layers for the radio frequency bands. Processing circuitry in the wireless access node selects one of the radio frequency bands based on the received signal strengths and the MIMO layers. The radio circuitry wirelessly exchanges user data with the wireless UE over the selected one of the frequency bands. In some examples, the processing circuitry also uses sector locations of the wireless UE for the frequency bands to select the one of the frequency bands.

  • Patent number: 11882491
    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.
