  • Patent number: 10498551
    Abstract: Methods, systems, and devices for wireless communication are described. Data for a broadcast or multicast service may be sent over a control channel. A network device may broadcast a message to indicate a plurality of enhanced multimedia broadcast multicast service (eMBMS) services offered by the network. The mobile device may transmit an indication to the network device identifying an eMBMS service of interest. The network device may transmit a configuration message before broadcasting or multicasting data of the eMBMS service of interest. The configuration message may notify the mobile device of a control channel on which to receive the data related to the eMBMS service. The network device may then broadcast or multicast the eMBMS service data on the control channel. The data may be segmented at a particular protocol layer and mapped to several transmission time intervals within each repetition of the control channel.

  • Publication number: 20190260669
    Abstract: A user equipment (UE) may identify a bearer (e.g., a default bearer) and request establishment of a second bearer (e.g., a high priority bearer) for use in streaming downlink data from, for example, an application server. The UE may determine a status of a playout buffer and select the first bearer or the second bearer for use in streaming the downlink data associated with the application based on the status of the playout buffer. For example, the first bearer may be used be used by default, and the second bearer may be selected if the amount of data in the playout buffer does not satisfy (e.g., is below) a threshold. In some cases, each bearer may be associated with a transmission control protocol (TCP) port associated with a TCP connection. In some cases, each bearer may be associated with different Internet protocol (IP) address.

  • Publication number: 20190239032
    Abstract: Methods, systems, and devices for wireless communications are described for providing local broadcasts for group calls. A user equipment (UE) may request a group call, and either a base station or a local server dedicated to the base station may determine whether to allow the group call based at least in part on an assessed level of interest for the group call. If the group call occurs, the UE may perform one or more aspects of user plane processing for the broadcast data—such as setting Internet protocol (IP) addresses in IP packets, encryption, compression, or media formatting—and may transmit the broadcast data to the base station. The base station may then transmit the broadcast data to one or more interested UEs via one or more multicast transmissions without routing the broadcast data through other network nodes, which may reduce latency and provide other benefits.
