  • Publication number: 20200107285
    Abstract: Generally, the described techniques provide for a device determining or receiving signaling including a packet delivery time window configuration that indicates delivery windows within which transmissions may be held and/or delivery opportunities within which communications are expected to be transmitted. For example, the device may identify a packet delivery time window configuration for communications with another device. The packet delivery window configuration may indicate a periodicity, offset, start time, end time, and/or duration of the delivery windows, among other information. Based on the identified packet delivery time window configuration, the device may delay transmission of the data packet (e.g., for the duration of one or more configured delivery windows). At, for example, the end of the respective delivery window, the device may deliver the data packet to a network device for which the information of the data packet is to be used.

  • Publication number: 20200107339
    Abstract: Generally, the described techniques provide for a core network signaling to a base station a delay budget configuration that indicates a determined latency for communications between a core network, base station, and a user equipment (UE). In some cases, the core network may determine a first variable delay budget between the core network and a base station based on capability information associated with the wireless communications system. The core network may transmit the delay budget configuration to the base station, where the delay budget configuration may include the first delay budget. The base station may be able to determine a delay between the UE and the base station based on the delay budget configuration. Using the delay budget configuration, the base station may then schedule communications with the UE.

  • Patent number: 10609613
    Abstract: The disclosure provides for a user equipment (UE) to change from a first network to a second network for an internet protocol (IP) multimedia subsystem (IMS) call. Initially, the UE has a connection to a first network providing an IP address for the UE. The UE may receive, via the first network, a message indicating an incoming IMS call. The UE may transmit one or more IMS call setup messages on the first network at an IP layer. The UE may change the connection from the first network to a second network that uses a same identifier for the UE (e.g., the IP address). The UE may complete setup of the IMS call on the second network using the same identifier for the UE.

  • Publication number: 20200059338
    Abstract: Methods, systems, and devices providing for media access control (MAC) control element (CE) configuration and triggering of sounding reference signal (SRS) are described. For example, a MAC packet data unit (PDU) may include MAC CEs and may indicate (e.g., via one or more bits in fields included in the MAC PDU, such as a MAC subheader) that one or more MAC CEs include one or more SRS configuration parameters. Such SRS configuration parameters may be used by a wireless device to determine an SRS configuration, or to update or reconfigure SRS configuration parameters of an existing or previously defined SRS configuration. In some cases, downlink control information (DCI) may be coupled to a MAC CE, such that the coupled DCI may provide additional SRS configuration parameters to be used in conjunction with SRS parameters indicated by the MAC CE. In such cases, the MAC PDU may indicate a coupling configuration.

A data flow may be established via the wireless communications network, in which one or more system messages associated with the data flow may provide timing information for the data flow. A first node within the wireless communications network may receive a request for establishing such a data flow with a user equipment (UE). The first node may receive timing information for the data flow via one or more system messages associated with the data flow, and establish the data flow based at least in part on the timing information.

  • Publication number: 20190373630
    Abstract: Methods, systems, and devices for wireless communication are described. A wireless device may receive a semi-persistent scheduling (SPS) grant of initial resources for receiving a transmission, receive, in a group control channel, a resource allocation for additional resources for receiving the transmission, determine resources for receiving the transmission based on the resource allocation and the SPS grant, and receive the transmission on the determined resources. A base station may transmit a SPS grant for scheduling a transmission on a set of resources, receive a feedback report from a user equipment (UE) indicating the UE requires additional resources for receiving the transmission, generate, based at least on the UE requiring the additional resources, a resource allocation for scheduling the additional resources for the UE, transmit the resource allocation in a group control channel, and transmit the transmission on the set of resources and the additional resources.

  • 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.
