Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A block-request streaming system provides for improvements in the user experience and bandwidth efficiency of such systems, typically using an ingestion system that generates data in a form to be served by a conventional file server (HTTP, FTP, or the like), wherein the ingestion system intakes content and prepares it as files or data elements to be served by the file server. The system might include controlling the sequence, timing and construction of block requests, time based indexing, variable block sizing, optimal block partitioning, control of random access point placement, including across multiple presentation versions, dynamically updating presentation data, and/or efficiently presenting live content and time shifting.
