  • Publication number: 20190297552
    Abstract: The present disclosure generally relates to techniques to increase reliability of communications within a network during a low reliability period. The network may include a user equipment (UE) communicatively coupled with one or more transmit/receive points (TRPs), with the communications between the UE and the one more TRPs requiring a reliability above a first reliability threshold. A processor of a network entity may identify a low reliability period which occurs when the reliability of the communications is determined to be below a second reliability threshold. The processor may cause the network to perform one or more remedial actions to increase the reliability during the low reliability period.

  • Publication number: 20190289616
    Abstract: Methods, systems, and devices for wireless communications are described. An access node may schedule traffic with different levels of priority for communications with a user equipment. The access node may receive a time-sensitive networking time-aware schedule from a first interface via an Ethernet frame that defines a set of periodic time intervals reserved for transmitting traffic with a high-priority (e.g., hard-real time traffic). In some cases, one or more frequency resources may additionally be reserved for the high-priority traffic. Accordingly, during the reserved time intervals, if the high-priority traffic is present, the access node may transmit the high-priority traffic on the reserved frequency resource(s). Outside the reserved time intervals, the access node may schedule lower-priority traffic on the reserved frequency resource(s) in addition to the other resources.

  • Publication number: 20190261394
    Abstract: Methods, systems, and devices for dynamic monitoring and scheduling in retransmission are described for wireless communications. For example, a receiving device may receive a data transmission in a first receiver bandwidth, determine that a data packet of the data transmission was unsuccessfully decoded, switch to a second receiver bandwidth that is wider than the first receiver bandwidth or narrower than the first receiver bandwidth (e.g., based on determining that the data packet was unsuccessfully decoded), and receive a retransmission of the data packet in the second receiver bandwidth. In another example, a transmitting device may schedule a data transmission according to a first receiver bandwidth, receive an indication that a data packet of the data transmission was unsuccessfully decoded, and schedule a retransmission of the data packet according to a second receiver bandwidth that is wider than the first receiver bandwidth or narrower than the first receiver bandwidth.

  • Patent number: 10368305
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may attempt to access a network at a local area network access point without prior context information. The access point may be a hotspot operating in unlicensed spectrum according to a Long Term Evolution (LTE)-based standard. The UE may be unable to determine if it is authorized to access the network, so the UE may attempt to obtain system information that provides a list of service providers supported by the network. The UE may then determine whether it has credentials for a supported service provider, and the UE may access the network using those credentials when a supported service provider is recognized. Other broadcast messages may provide information about system information for supported service providers. A UE that is unable to access the network using stored credentials may attempt access using a random access channel procedure.

  • Publication number: 20190190635
    Abstract: Methods, systems, and devices for wireless communications are described. A first node (e.g., a user equipment (UE)) may receive a timing synchronization signal from a second node (e.g., a base station) over a cellular wireless communication link. In some aspects, the timing synchronization signal may indicate mapping information to synchronize the first node with the second node. The mapping information may be for synchronizing a first time of a first clock of the first node to a second time of a second clock of a second node. The first node may synchronize the first time of the first clock to the second time of the second clock based at least in part on the mapping information and the synchronization information. The first node may transmit a timing control based on a timing of the second clock to a device connected to the first node via a local wired interface.

  • Publication number: 20190174314
    Abstract: Aspects of the present disclosure describe authentication of a user equipment (UE) in a network. It can be determined, by the UE, to access a discovered network for wireless communications, and based on a service provider associated with the discovered network, to use a modified universal subscriber identity module (USIM) subscription stored in the UE for authentication with the discovered network. The UE can obtain a subscriber identifier for authenticating on the discovered network via the authentication, where the subscriber identifier is generated based at least in part on a service provider identifier associated with the service provider and a modified mobile subscriber identity associated with the service provider. The UE can send the subscriber identifier to a node of the discovered network for the authentication.

  • Patent number: 10271227
    Abstract: Methods, systems, and devices for enhanced neighbor discovery through enhanced automatic neighbor relations (ANR) and for detecting cell identifier confusion and are described. Neighboring base stations may provide information to one another, including using ANR, that may avoid or help to resolve cell identity confusion. For example, a NHN-ID may be defined to avoid or resolve cell identify confusion. A wireless device, such as a base station or a user equipment (UE), may determine whether neighboring cells are using a common cell identifier and may adjust operations accordingly. For example, a device may detect physical cell identity (PCI) confusion by determining whether two neighboring cells have the same PCI and different Evolved Universal Terrestrial Access Network (E-UTRAN) Cell Global Identifiers (ECGIs) or different Neutral Host Network Identifier (NHN-IDs). A network entity may then inform the neighboring cells having the same PCI of the confusion.

  • Patent number: 10182421
    Abstract: A method for managing spectrum resources by a network node in a wireless communication system may include determining an availability of a first channel of a spectrum, and assigning a second channel to a secondary carrier in response to determining that the first channel is available. In the alternative, or in addition, the method may include unassigning the second channel to the secondary carrier in response to determining that the first channel is unavailable. The spectrum may be, or include, Authorized Shared Access (ASA) spectrum. The method may be performed by one or more nodes of a network that is a secondary user of the spectrum. The channel may be deemed unavailable when in use by a primary user of the ASA spectrum. A wireless communication apparatus include a processor coupled to a memory holding instructions for execution by the processor to cause the apparatus to perform operations as described above.
