Abstract: A user equipment (UE) may be configured to join a group call, which may include mission critical (MC) data. The UE may be configured to receive, through a broadcasted group discovery channel (GDCH), a list of group call services and corresponding session description protocol (SDP) information for establishing the group call services. The UE may be configured to determine at least one group call service of the group call services to receive. The UE may be configured to establish the at least one group call service based at least in part on the corresponding SDP information received through the broadcasted GDCH.

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: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be a UE that performs a PTT/PTX call setup for communication via MBMS. In a first configuration, the UE sets up a unicast bearer with an eNB, and sends group call setup signaling to the eNB while setting up the unicast bearer. In a second configuration, the UE sets up a unicast bearer with an eNB, and receives group call setup signaling from the eNB while setting up the unicast bearer. In a third configuration, the UE receives a group page while in an RRC idle state, and receives group call setup signaling based on information in the group page.

Abstract: An example client device includes a middleware unit for receiving media data either via a broadcast service or a unicast service, depending on whether the broadcast service is available. The client device also includes a streaming client, such as a Dynamic Adaptive Streaming over HTTP (DASH) client. The DASH client sends requests to retrieve media data via the middleware unit. The middleware unit may cache media data received via the broadcast service, such that even when the broadcast service is not active, if the streaming client requests media data that was previously received via the broadcast service, the middleware unit may provide the media data to the streaming client from the cache, rather than requesting the media data from an external server device specified in the request from the streaming client.

Abstract: An example device for advertising a segment availability time when transporting media data includes a middleware unit configured to determine a playback duration, X, for segments of media data, determine a current time at a first scheduled burst, aburst, of a multicast channel (MCH) scheduling period (MSP) for a first segment having segment number a, determine an MSP duration, DMSP, calculate a segment availability time for a second segment having segment number b according to a formula that uses X, aburst, a, b, and DMSP as inputs, and advertise the segment availability time for the second segment.

Abstract: Embodiment systems, methods, and devices enable data streams of a broadcast service to be carried in multiple communication sessions in any transport protocol providing file transport information and the transmission of objects, an example of which is File Delivery Over Unidirectional Transport (“FLUTE”). A session description may include a category attribute indicating the type of data carried in such a protocol session. A schedule fragment may include references to a session description for each such protocol session associated with a service. A common listing of configuration parameters may be generated for all such protocol sessions associated with a service. A different listing of configuration parameters may be generated for each such protocol session associated with a service. A flag setting in a diary file may indicate one or more such protocol session associated with a service over which in-band update fragments may be broadcast.

Abstract: A UE receives a list of neighboring cells of a serving cell serving the UE, and a list of SAIs. The list of neighboring cells may be included in a first system information message and the list of SAIs may be included in a second system information message. The first and second messages may be the same message, e.g., SIB15, or may be different messages SIB4/SIB5 and SIB15. The list of SAI includes those SAI supported by at least one of the serving cell and the neighboring cells. At least one of the SAIs is formatted to include mapping information that maps the SAI to one or more of the neighboring cells included in the list of neighboring cells. The UE processes the at least one SAI to determine the one or more neighboring cells that support the SAI.

Abstract: A device for receiving streaming data includes a broadcast or multicast middleware unit configured to receive the streaming data via a second service and a proxy unit configured to be disposed between the middleware unit and a client application, the proxy unit further configured to receive an indication of whether the streaming data is to be received via a first service or the second service, when the indication indicates that the streaming data is to be received via the first service: disable the middleware unit; and receive the streaming data via the first service, and when the indication indicates that the streaming data is to be received via the second service: activate the middleware unit to receive the streaming data via the second service, wherein the second service comprises at least one of a broadcast service or a multicast service; and receive the streaming data from the middleware unit.
