Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may transmit, to a second network node during a first time period, at least one packet of a first protocol data unit (PDU) set, the at least one packet of the first PDU set comprising PDU set information associated with a second PDU set. The first network node may transmit, to the second network node during a second time period that occurs subsequent to the first time period, at least one packet of the second PDU set. Numerous other aspects are described.

Signaling of protocol data unit set information

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

Techniques and systems are provided for image processing. For instance, a process can include obtaining, from one or more image sensors, a first image of an environment; determining semantic labels for a plurality of pixels of the first image based on whether each pixel of the plurality of pixels is associated with an object in the first image to generate a semantically segmented image; applying a two-dimensional line representation of the first image to the semantically segmented image to generate a labeled 2D line representation; back-projecting the labeled 2D line representation to three dimensions to generate a line representation model; fusing the line representation model and the semantically segmented image to generate a labeled line representation model; and outputting the labeled line representation model.

Edge-based geometry representation for cross layer applications

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

Various embodiments provide systems and methods for supporting synchronized delivery of packets of different type media streams of a service. Various embodiments enable wireless device and/or network assistance of packet synchronization in downlink (DL) and/or uplink (UL) transmissions.

Supporting inter-media synchronization in wireless communications

In an aspect, an answerer receives, from an offeror, a first plurality of quality of service (QoS) parameters for a multimedia session, the first plurality of QoS parameters including first loss and/or latency parameters indicating first desirable maximum end-to-end packet loss and/or latency for the multimedia session, determines that the first desirable maximum end-to-end packet loss is higher than a second desirable maximum end-to-end packet loss, the first desirable maximum end-to-end packet latency is higher than a second desirable maximum end-to-end packet latency, or both, and sends, to the offeror, a second plurality of QoS parameters for the multimedia session, the second plurality of QoS parameters including a second loss parameter indicating the second desirable maximum end-to-end packet loss, a second latency parameter indicating the second desirable maximum end-to-end packet latency, or both.

Considerations on quality of service (QOS) hints for an uplink streaming service

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

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

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

Methods and apparatus are disclosed for session initiation in a conference. In one aspect, a method for communicating between multiple parties is disclosed. The method comprises generating, at a first device, a first message for transmission to a second device. The method further comprises receiving, at the first device, a second message for establishing a conference. The second message includes a list of one or more concurrent codec capabilities supported by the second device. The list of one or more concurrent codec capabilities supported by the second device comprises an indication of whether one or more resources usable for one or more concurrent instances of a first listed codec may instead be used for one or more concurrent instances of a second listed codec.

Methods and apparatus for use of compact concurrent codecs in multimedia communications

Various embodiments may provide methods, systems, and devices for supporting application level discovery of Radio Access Network (RAN) statistics and/or events. Various embodiments may provide methods, systems, and devices for supporting application level signaling of Quality of Service (QoS) requirements.

Interface between a radio access network and an application

Methods, systems, and devices for wireless communications are described. A wireless communications entity, such as a user equipment (UE), a base station, a network core, or an application server, may identify a round-trip time (RTT) latency requirement that may pertain to a round-trip latency in wireless communications between the UE and the base station. The wireless communications entity may identify a one one-way directional delay budget that satisfies the RTT latency requirement for an application of an application server. The application server may be in communication with the UE via the base station. The wireless communications entity may modify a value of the one-way directional delay budget and transmit a message that is associated with the modified value of the one one-way directional delay budget.

Round-trip time as a latency performance indicator

An example device for processing extended reality (XR) data includes a processors configured to: parse entry point data of an XR scene to extract information about one or more required virtual objects for the XR scene, the required virtual objects including a number of dynamic virtual objects equal to or greater than one, each of the dynamic virtual objects including at least one dynamic media component for which media data is to be retrieved; initialize a number of streaming sessions equal to or greater than the number of dynamic virtual objects using the entry point data; configure quality of service (QoS) and charging information for the streaming sessions; retrieve media data for the dynamic virtual objects via the streaming sessions; and send the retrieved media data to a rendering unit to render the XR scene to include the retrieved media data at corresponding locations within the XR scene.

Split rendering of extended reality data over 5G networks

A method of communication includes receiving configuration data at a first device, the configuration data indicating a first packet loss rate threshold associated with a first codec configuration. The method includes determining a packet loss rate at the first device, the packet loss rate associated with one or more first packets received at the first device from a second device. The method includes, based on determining that a decoder of the first device has the first codec configuration and that the packet loss rate satisfies the first packet loss rate threshold, sending, to the second device, a request to change a codec configuration of the second device. The method also includes receiving a second packet at the first device from the second device, the second packet encoded based on a second codec configuration.

Codec configuration adaptation based on packet loss rate
