Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication that a 5G media streaming (5GMS) service is partially available over a 5G multicast/broadcast service (5MBS). The UE may receive information that indicates a first set of resources of the 5GMS service that are accessible or delivered via 5G unicast, and a second set of resources of the 5GMS service that are accessible or delivered via 5MBS, wherein the second set of resources are hosted on a server of the UE. The UE may receive or transmit data associated with the 5GMS service. Numerous other aspects are described.

Abstract: A client device (e.g., user equipment or "UE") may be configured to engage in a media communication session, such as a WebRTC session, with another client device. The client devices may separate a quality of service (QoS) specification from a QoS flow definition, to allow for separate interactive connectivity establishment (ICE) negotiation. The QoS specification may cover all segments of a connection for the media communication session. For example, QoS may be requested for a case where a server (e.g., a Traversal Using Relay Network Address Translation (TURN) server) is hosted by a mobile network operator (MNO). The QoS specification and the QoS flow description may be linked.

Abstract: The present disclosure relates to methods and devices for wireless communication including an apparatus, e.g., a UE and/or one or more networks. In one aspect, the apparatus receives an MBMS video streaming service through broadcast from a first network. In addition, the apparatus determines a failure in association with the reception of the broadcasted MBMS video streaming service. Further, the apparatus receives, based on the determined failure of the broadcasted MBMS video streaming service, the MBMS video streaming service through unicast from a second network. In one configuration, the apparatus transmits information to the second network indicating that the MBMS video streaming service through broadcast from the first network has failed. In such a configuration, the MBMS video streaming service through unicast from the second network is received based on the transmitted information.

Abstract: A device for retrieving media data includes a memory configured to store media data of a media presentation; and one or more processors implemented in circuitry and configured to: retrieve a manifest file for the media presentation, the manifest file including data for an initialization set, the initialization set including initialization parameters for the full duration of the media presentation; initializing playback of the media data of the media presentation using the initialization set; retrieving the media data of the media presentation; and present the media data according to the initialized playback. For example, the initialization parameters may specify a maximum width or a maximum height of pictures of the media presentation or a maximum frame rate of the media presentation. Thus, the processors can process pictures of any size less than or equal to the maximum width/height, or media data equal to or less than the maximum frame rate.

Abstract: A media device pre-fetches media data that is likely to be retrieved. An example media device includes a memory for storing media data, and one or more processors implemented in circuitry and configured to receive information indicating at least one data structure of a plurality of data structures that is likely to be retrieved by a plurality of user devices operated by a respective plurality of users, the data structure including media data, and retrieve the media data of the data structure before receiving requests for the media data from the user devices. The information may be included in, e.g., a manifest file, a special Parameters Enhancing Delivery (PED) message, and/or a separate track of a video file multiplexed with other tracks of the video file.
