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.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications. In some aspects, a mobile device may receive configuration information, associated with configuring a state of the mobile device, via a unicast transmission, and may access a header-compressed broadcast transmission using the configuration information received via the unicast transmission. In some aspects, a network entity may transmit configuration information, to facilitate decompression of a header-compressed broadcast transmission, via a unicast transmission to a mobile device of a plurality of mobile devices, and may transmit the header-compressed broadcast transmission to the plurality of mobile devices in accordance with the configuration information.

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.
