  • Patent number: 10778384
    Abstract: A base station may include one or more processors to receive repetitive data transmitted using a set of subcarriers of a physical resource block (PRB); apply a first orthogonal pattern, assigned to a first user equipment (UE), to a segment of subframes of the received repetitive data; apply a second orthogonal pattern, assigned to a second UE, to the segment of subframes of the received repetitive data, the second orthogonal pattern being different from the first orthogonal pattern; determine first repetitive data, transmitted by the first UE using the set of subcarriers, based on applying the first orthogonal pattern to the segment of subframes of the received repetitive data; and/or determine second repetitive data, transmitted by the second UE using the set of subcarriers, based on applying the second orthogonal pattern to the segment of subframes of the received repetitive data.

  • Publication number: 20200228967
    Abstract: A user device provides, to a network, information associated with the user device, and receives, from the network, a multi-bit network indication that indicates access technologies, services, and network capabilities provided by the network. The user device determines whether the user device is in a home network or a visited network based on the multi-bit network indication. The user device passes bits of the multi-bit network indication to an upper layer when the user device is in the home network or passes a portion of the bits of the multi-bit network indication to the upper layer when the user device is in the visited network. The user device receives a selection of one of the access technologies, the services, or the network capabilities, and receives, from the network, the one of the access technologies, the services, or the network capabilities for the user device based on the selection.

  • Patent number: 10660067
    Abstract: A system described herein may provide a mechanism for efficiently delivering messages to a User Equipment (“UE”) associated with a wireless telecommunications network, such as a UE that is frequently in an inactive state. A message for the UE may be received and buffered. Once the network determines that the UE has transitioned from the inactive state to the active state (e.g., as detected by a Mobility Management Entity (“MME”) or an Access and Mobility Management Function (“AMF”)), the buffered message may be provided to the UE using control plane signaling.

  • Publication number: 20200137621
    Abstract: Systems and methods enable a wireless station in a radio access network to apply slice-based admission control. A wireless station receives, from a core network, network slice data for each network slice available via the wireless station, wherein the network slice data includes a slice identifier and corresponding slice status for each network slice; and receives, from a user equipment (UE) device, a service request that indicates a network slice identifier previously assigned to the UE device. The wireless station applies, based on the network slice data from the core network and the network slice identifier from the UE device, admission controls to forward the service request to the core network when the one of the network slices, corresponding to the network slice identifier, is not congested, and delay or redirect the service request when the one of the network slices, corresponding to the network slice identifier, is congested.

  • Publication number: 20200099580
    Abstract: A wireless network provides differentiated service via a first management device that manages and provisions resources that are located in an edge cloud of the wireless network separate from a second management device that manages and provisions resources that are located in a core cloud of the wireless network. The first management device may provision the edge cloud resources to provide various functionalities and services of the wireless network in a localized manner to user equipment (“UEs”) that are associated with low latency or high reliability requirements. The second management device may provision the core cloud resources to provide the same or different functionalities and services of the wireless network in a centralized manner to UEs that are not associated with low latency and high reliability requirements.

  • Publication number: 20200068430
    Abstract: A method, a device, and a non-transitory storage medium are described in which a network slice-based admission and congestion control service is provided. The congestion control service monitors for congestion in a network slice. When congestion is detected, the congestion control service may adjust an allotment of a resource of a network device or the resource of the network slice from end-to-end. When neither of these adjustments can be made, the congestion control service may use a network slice-based access control barring.

  • Patent number: 10575189
    Abstract: A method for network controlled beam sweeping, may include receiving, at a network control device, location data associated with user equipment (UE) devices within a service area. The method may also include identifying, at each beam sweeping position of a plurality of beam sweeping positions, geo-bins having at least one UE device located within. The method includes receiving, at the network control device, networking requirements and traffic distribution data associated with the UE devices, and determining a sweeping weight for each identified geo-bin, where the sweeping weight is based on the networking requirements and the traffic distribution data associated with the at least one UE device in a geo-bin, and determining a sweeping factor for each beam sweeping position based upon the sweeping weights. The method may also include determining a beam sweeping pattern for all the beam sweeping positions based on the sweeping factors.

  • Patent number: 10548029
    Abstract: A user device receives system information block data from a cell. The user device obtains, from the system information block data, cell metadata that includes a cellular parameter. The user device parses the cell metadata to identify the cellular parameter. The cellular parameter includes an upper layer indicator element, a public land mobile network (PLMN) information list element, and a network capability indicator element. The user device determines, based on the cellular parameter, that the cell is of a particular cell type of a plurality of cell types, and that the cell has a particular capability of a plurality of types of capabilities. The user device performs an action based on the particular cell type or the particular capability.

  • Publication number: 20190342735
    Abstract: A method includes receiving, at a network control component, an enhanced subscriber profile identifier (E-SPID) associated with at least one machine type communications (MTC) user device from a home subscriber server (HSS). The method includes determining whether the E-SPID is in a first range of E-SPID values, wherein the first range of E-SPID values corresponds to a delay that exceeds a threshold, and interacting with a self-organizing network (SON) controller that interacts an operation administration maintenance (OAM) component to control and define a modified E-SPID based on network traffic and coverage in response to a determination that the E-SPID is in the first range of E-SPID values. The method further includes sending the modified E-SPID to at least one enhanced evolved node b (eNodeB) associated with the at least one MTC user device, wherein the at least one enhanced eNodeB is operable to perform access control and scheduling for the at least one MTC user device based on the E-SPID.
