In embodiments of systems and methods for synchronous content presentation, an Edge server device may receive a decryption key for an encrypted content segment that is or will be delivered to a plurality of wireless devices over the wireless communication network, and may send the decryption key to the plurality of wireless devices after the encrypted content segment has been received by the plurality of wireless devices in a manner that enables the plurality of wireless devices to decrypt the encrypted content segment approximately simultaneously. A wireless device may receive, and optionally temporarily store, the encrypted content segment from the wireless communication network, receive the decryption key from the Edge server device after receiving the encrypted content segment, and decrypt the stored encrypted content segment using the received decryption key.

Synchronous content presentation

An example device for exchanging media data via a network includes a memory configured to store media data; and one or more processors implemented in circuitry and configured to: retrieve data representative of an expected time between a first frame of media data and a second frame of the media data from a media application; receive the first frame of the media data at a first time; wait to process the second frame of the media data until a second time that is equal to or greater than the first time plus the expected time; and process the second frame of the media data at the second time.

Signaling media timing information from a media application to a network element

Disclosed are techniques for wireless communication. In an aspect, a network node configures a quality of service (QoS) profile comprising one or more file-level QoS parameters, wherein the QoS profile applies to one or more files associated with a service flow associated with a user equipment (UE), wherein each file of the one or more files comprises one or more protocol data units (PDUs), and wherein a header of each PDU of the one or more PDUs of the file includes a file identifier and a file type of the file, and enforces the QoS profile on the one or more files.

High bandwidth low latency cellular traffic awareness

Various embodiments may provide streaming service downlink network assistance and/or uplink network assistance mechanisms in a fifth generation (5G) system (5GS) network via an Application Function (AF) computing device in a 5GS. In some embodiments, a computing device and/or the AF computing device may inform the network about needs for capacity for downlink or uplink traffic. Various embodiments may include sending radio access network (RAN) capacity requests to a network computing device of the 5GS network including a 5G RAN. In some embodiments, the network computing device of the 5GS network may be a computing device that is not part of the 5G RAN. In some embodiments, capacity need messages may be sent directly from user equipment (UE) computing devices to computing devices of the 5G RAN. In some embodiments, capacity information of the RAN may be delivered to an AF computing device via an intermediate network function.

Uplink and downlink streaming bit rate assistance in 4G and 5G networks

The present disclosure relates to methods and devices for facilitating using a streaming manifest including a profile signal for content encoded based on a encapsulation format. An example method disclosed herein includes identifying structures associated with first media, wherein the first media is associated with a first streaming format. The example method also includes generating a streaming manifest for the first media, wherein the streaming manifest maps the structures associated with the first media to structures associated with a second streaming format, and including an indication with the streaming manifest, wherein the indication identifies the streaming profile used to map the structures.

Methods and apparatus to facilitate using a streaming manifest including a profile indication

An example device for retrieving media data includes one or more processors implemented in circuitry and configured to receive a manifest file including data indicating a number of segment chunks available for a segment of a representation of media data, the segment comprising an independently retrievable media file having a unique uniform resource locator (URL), determine an identifier for one of the chunks using the data indicating the number of chunks available for the segment, and send a request specifying the identifier for the one of the chunks to a server device.

Retrieving and accessing segment chunks for media streaming

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, a multicast-broadcast user service description message. The UE may communicate, using a multicast-broadcast service (MBS) transport function (MBSTF) client, with an MBS entity of the network entity, in accordance with information included in the user service description message, wherein the MBS entity is split into a multicast delivery function and a unicast application server. Numerous other aspects are described.

Multicast-broadcast user service architecture

Embodiments include methods performed by a processor of a mobile device for allocating resources to a plurality of mobile devices in communication with an Edge network. The processor may receive from the plurality of mobile devices one or more capabilities of each mobile device related to a computing task in which the plurality of mobile devices are participating. The processor may determine a fairness result for the plurality of computing devices based on the one or more capabilities of each mobile device and the computing task. The processor may allocate resources to each of the plurality of mobile devices based on the determined fairness result.

Allocating resources to a plurality of mobile devices

In embodiments of systems and methods for managing end-to-end Quality of Service (QoS) in a communication path spanning a first communication network and a second communication network may include determining by a network element of the first communication network an end-to-end QoS requirement for communicating packets from a packet source to a packet destination via the communication path, determining by the network element a QoS provided by the second communication network within the communication path, and configuring the first communication network to provide sufficient QoS to support the end-to-end QoS requirement based on the QoS provided by the second communication network.

Managing end-to-end quality of service (QoS) in a multi-network communication path

Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication by a user equipment (UE). The method generally includes receiving a public warning system (PWS) message, wherein the PWS message includes information associated with at least one program provided via a multimedia service, and retrieving the at least one program via the multimedia service based on the information indicated in the PWS message.

Convergence of public warning system (PWS) and multimedia service for emergency broadcast

Aspects described herein relate to managing and/or configuring, for a user equipment (UE), unicast and/or multicast radio bearers for unicast and/or multicast cells based on measurement reports generated by the UE.

Techniques for multicast and unicast convergence in wireless communications

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.

Supporting quality of service for media communications

An example device for transporting media data includes: a memory configured to store media data; and one or more processors implemented in circuitry and configured to: determine that a manifest file for a media presentation includes data representing a delta time value for a resynchronization element of a segment of the media presentation; determine a multiple of the delta time value; determine a number of chunks of the segment that are currently available for retrieval using the multiple of the delta time value; send a request to a server device for the chunks of the segment that are currently available, wherein the request omits chunks of the segment that are not currently available; and store data of chunks received in response to the request in the memory.

Determination of availability of chunks of data for network streaming media data

A device for receiving 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 service description including data including one or more playback preferences for the media presentation, the playback preferences including a desired end-to-end latency; retrieve the media data of the media presentation via a network streaming protocol; and present the retrieved media data according to the one or more playback preferences and to achieve the desired end-to-end latency. For example, the playback preferences may specify acceleration or deceleration of playback rates in order to achieve the desired end-to-end latency. Thus, the device may accelerate playback if a buffer is filling too quickly, or decelerate playback if the buffer is emptying too quickly, to prevent buffer overflow or underflow and thereby avoid playback interruptions without changing the latency.

Service description for streaming media data

A base station may perform interleaving of parts of a plurality of transport blocks for a broadcast or multicast transmission across a plurality of time intervals. A size of a transport block of the plurality of transport blocks may be scaled by a scaling factor. The base station may transmit the interleaved parts in the plurality of time intervals.
