  • Patent number: 11737075
    Abstract: Systems and methods are provided for dynamically reallocating available transmit power on a dual connectivity user device. A retransmission rate is monitored for the user device that can simultaneously communicate using two or more wireless communication protocols. It is determined that the retransmission rate for the user device is above a threshold for communications using a first wireless communication protocol, such as LTE. Channel assignment of a second wireless communication protocol, such as 5G, is reduced, thus allowing the user device to reallocate a portion of the transmit power previously allocated for the second wireless communication protocol to the first wireless communication protocol to improve the retransmission rate for the first wireless communication protocol.

  • Publication number: 20230261705
    Abstract: To wirelessly communicate through a physical barrier, a network communication device determines uplink beamforming information and uplink power information. The network communication device wirelessly transfers the uplink beamforming information and the uplink power information to a serving communication device. The serving communication device wirelessly receives the uplink beamforming information and the uplink power information. The serving communication device receives an uplink signal from a user communication device. The serving communication device beamforms the uplink signal based on the uplink beamforming information. The serving communication device amplifies the uplink signal based on the uplink power information. The serving communication device wirelessly transfers the beamformed and amplified uplink signal to the network communication device. The network communication device wirelessly receives the beamformed and amplified uplink signal from the serving communication device.

  • Patent number: 11729766
    Abstract: A primary wireless access node receives signaling that indicates primary power headroom for a User Equipment (UE) when transmitting to the primary wireless access node and secondary power headroom for the UE when transmitting to a secondary wireless access node. The primary wireless access node determines a primary uplink grant and a secondary uplink grant for the UE and transfers the secondary uplink grant amount to the secondary wireless access node. The primary wireless access node wirelessly transfers the primary uplink grant to the UE and wirelessly receives primary user data from the UE based on the primary uplink grant. The secondary wireless access node receives the secondary uplink grant from the primary wireless access node. The secondary wireless access node wirelessly transfers the secondary uplink grant to the UE and wirelessly receives secondary user data from the UE based on the secondary uplink grant.

  • Patent number: 11729698
    Abstract: A wireless access node serves slice-capable User Equipment (UEs) and slice-incapable UEs. In the wireless access node, a radio exchanges slice data between the slice-capable UEs and a Baseband Unit (BBU). The radio exchanges non-slice data between the slice-incapable UEs and the BBU. The BBU exchanges the slice data with a wireless network slice and exchanges the non-slice data with a network element. The BBU determines its load for the slice-capable UEs. The BBU controls access to the wireless access node by new slice-incapable UEs based on the load for the slice-capable UEs.

  • Publication number: 20230254747
    Abstract: Methods and systems are provided for signal offloading in an mmWave environment (e.g., in the event of high fading). The methods and systems include one or more mmWave nodes that are each configured to wirelessly communicate with a user device in a geographic service area and a Wi-Fi access point configured to wirelessly communicate with the user device. The methods and systems determine that fading or loading of an mmWave signal transmitted by one of the one or more mmWave nodes is above a threshold. In response to the fading or loading being above the threshold, the methods and systems redirect a control signal of the user device through the Wi-Fi access point to the one or more mmWave nodes, such that the user device maintains a dual connection with the Wi-Fi access point via the control signal and the mmWave node.

  • Patent number: 11723096
    Abstract: A method and system for controlling connectivity of a user equipment device (UE), the UE being dual-connectivity capable. The UE detects that the UE has ping-ponged at a threshold high rate between standalone connectivity and dual connectivity. And responsive to at least detecting that the UE has ping-ponged at the threshold high rate between standalone connectivity and dual connectivity, the UE transmits, to an access node serving the UE, a report including an indication that the UE is not dual-connectivity capable, even though the UE is dual-connectivity capable. The access node could then use the indication in the report as a basis to forgo configuring of dual connectivity for the UE, which could thereby help discontinue the ping-ponging.

  • Patent number: 11723099
    Abstract: When a first access node is considering setup of dual-connectivity service for a UE, the first access node could determine that the UE supports dual-band dual-connectivity service in which the UE would be served concurrently by a first access node, under a first radio access technology (RAT) over a first connection on a first frequency band and by a second access node, under a second RAT over a second connection on a second frequency band. To help optimize service when faced with the ability to set up either single-band dual-connectivity for the UE or dual-band dual-connectivity for the UE, the first access node will set up single-band dual connectivity for the UE.

  • Patent number: 11722928
    Abstract: A wireless communication network serves a wireless User Equipment (UE) over a working network slice and a protect network slice. In the wireless communication network, the UE transfers UE capability data to a network control-plane that indicates the working network slice and the protect network slice. The network control-plane generates UE context for the working network slice and the protect network slice. The network control-plane signals the UE context to the UE and to a network user-plane. The UE and network user plane exchange user data over the working network slice based on the UE context. The UE determines when the performance of the working network slice triggers a slice switch based on the UE context. In response to the slice switch, the UE stops using the working network slice. The UE and network user-plane exchange user data over the protect network slice based on the UE context.

  • Publication number: 20230247470
    Abstract: Systems and methods are provided for dynamically changing a channel state information (CSI) reporting protocol by adjusting CSI reporting frequency for a wireless device communicating with an access node within a wireless network. The methods and systems identify a power headroom (PHR) value at a particular wireless device and adjust the CSI reporting frequency when the PHR satisfies a predetermined threshold. The method changes the CSI reporting frequency for the wireless device to enable more frequent CSI reporting over a primary path to the access node to facilitate reallocation of resources.
