The handling of scalable data streams by network entities is rendered less complex by, in the data stream, accompanying packets which actually carry data by packets of a different packet type which have a scalability axes descriptor defining the number of scalability axes and a semantic meaning thereof. In another aspect, the handling of scalable data streams by network entities is rendered more efficient by conveying level and/or profile descriptors using packets other than the data carrying packets, with profile and/or level descriptors being divided up into a first set explicitly signaling the definition of the available coding option set and/or available syntax element value range for a respective operation point, and a second set of profile and/or level descriptors which signal the definition of the available coding option set and/or available syntax element value range for their respective operation points by reference another profile and/or level descriptor.

Scalable data stream and network entity

Concepts are described, including encoding, processing and decoding of a data stream having a video encoded thereinto, wherein the video comprises a plurality of pictures, wherein the data stream comprises a plurality of pictures in at least two layers, wherein the pictures of at least one layer are split into a predetermined layer-specific number of subpictures, one or more of the pictures or subpictures of one layer corresponds to one picture or subpictures in one or more other layer, and at least one of the subpictures comprises boundaries for boundary extension for motion compensation, and an indication that at least one of the boundaries of corresponding subpictures or corresponding pictures in different layers are aligned with each other.

A video decoder () for decoding an encoded video signal comprising encoded picture data to reconstruct a plurality of pictures of a video sequence of a video. The video decoder () comprises an input interface () configured for receiving the encoded video signal comprising the encoded picture data. Moreover, the video decoder () comprises a data decoder () configured for reconstructing the plurality of pictures of the video sequence depending on the encoded picture data. Moreover, further video decoders, video encoders, systems, methods for encoding and decoding, computer programs and encoded video signals according to embodiments are provided.

An apparatus for providing immersive media content to a plurality of receivers is described. The apparatus obtains for a representation of the immersive media content a plurality of tiles, the plurality of tiles covering some or all of the representation, and, for some or all of the plurality receivers, transmits to each receiver one or more of the tiles, the one or more tiles covering at least a viewport associated with the respective receiver.

Immersive viewport dependent multiparty video communication

A user device, UE, for a wireless communication system communicates with one or more further UEs using a sidelink, SL. The UE is to operate in a Discontinuous Reception, DRX, mode. When being out-of-coverage, the UE is to obtain one or more resources available for a transmission

Interpolation between explicitly signaled CPB (or HRD) parameters at selected bit rates is used to achieve a good compromise between CPB parameter transmission capacity and CPB parametrization effectiveness and may be, particularly, made in an effective manner.

Video coding using a coded picture buffer

An embodiment of a user equipment supports conditional handovers to one or more cells of a cellular network. The user equipment is configured to receive configuration data from the cellular network. The configuration data indicates for a plurality of target cells of the cellular network, conditions to trigger a conditional handover to any of the target cells. The user equipment is further configured to check the conditions with respect to appliance, and, in case of appliance, trigger the conditional handover.

A concept for transmitting information from a client to a server is described, the client being for streaming visual content from the server and for integrating the visual content into a 3D scene of a user application, and the client being for obtaining a rendered view of the 3D scene.

Client-server communication for streaming of visual content

A video decoder for decoding a video from a data stream is configured to decode an indication from the data stream which is valid for a sequence of pictures of the video, and indicates that RASL pictures within the sequence of pictures are coded in a manner excluding a predetermined set of one or more coding tools.

Video coding concept allowing for limitation of drift

A video data stream is rendered reducible in a manner so that the reduction leads to a restriction of pictures of the reduced video data stream to merely a predetermined subarea of the pictures of the original video data stream and in a manner so that transcoding, such as re-quantization, may be avoided and a conformance of the reduced video data stream relative to the codec underlying the original video data stream be maintained. This is achieved by providing the video data stream with information including an indication of the predetermined subarea and replacement indices for redirecting the indices included by the payload portion so as to refer to, and/or replacement parameters for adjusting the first set of coding parameter settings so as to result in, a second set of coding parameter settings.

Concept for picture/video data streams allowing efficient reducibility or efficient random access

A device for communicating in a wireless communication network to transmit transmission information by transmitting a wireless signal in a random access channel of wireless communication network includes a wireless interface configured for transmitting the wireless signal and a control unit configured for providing the wireless signals so as to include a random access preamble. The control unit is configured for selecting the random access preamble/that the random access preamble is associated with the transmission information.

Data-centric event-based random access procedure

A user device, UE, for one or more wireless communication systems, includes one or more transceiver chains. The UE shares at least one transceiver chain with at least two connections to the one or more wireless communication systems. The UE is connected to one or more network entities, like a gNB or another UE, with the connections, and perform one or more operations on the connections at respective operation occasions. When the UE transmits or receives on a current one of the connections, it does not to transmit or receive on the other connections.

In the field of wireless communication systems or networks, the design of resource pools as they may be used in sidelink communications among users of the wireless communication system, for example in V2X applications, is described. In particular, an improved resource pool design, for example for resource pools to be used in sidelink communications in V2X services in view of the advantages defined by the NR 5G standard, is presented.

A user device, UE, for a wireless communication system is described. The wireless communication system has a plurality of user devices, UEs. The UE communicates with one or more further UEs using a sidelink, SL. To operate in a Discontinuous Reception, DRX, mode, the UE receives a DRX configuration from one of a plurality of DRX configuration sources. The plurality of DRX configuration sources are ranked such that each of the DRX configuration sources has a rank different from the remaining DRX configuration sources, and the UE is to select the DRX configuration from the DRX configuration source having the highest rank among the available DRX configuration sources.

NR sidelink discontinuous reception

A user device, UE, for a wireless communication system is described. The wireless communication system includes a plurality of user devices, UEs. The UE communicates with one or more transmitting UEs using a sidelink, supports a certain number of HARQ processes, and buffers one or more transmissions for each HARQ process. During a unicast communication with a transmitting UE using the sidelink, the UE receives from the transmitting UE a transmission during a transmission time interval, the transmission associated to control data, e.g. SCI, including a HARQ process ID, buffers the received transmission for the HARQ process, and combines the buffered transmissions prior to decoding. In case a successfully identified transmission is not buffered, the UE indicates to the transmitting UE that the transmission is not buffered at the UE.
