Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor one or more first conditions pertaining to non-cellular communications between the UE and a non-cellular network while the UE is operating in a dual networking mode for steering, switching, or splitting traffic (e.g., an access traffic steering, switching, and splitting (ATSSS) mode) between the non-cellular network and a cellular network. The UE may predict an availability status of at least the non-cellular network based on at least one of the one or more first conditions. In some cases, the UE may determine whether to change dual networking modes based on the availability status and may communicate in accordance with the same or a different dual networking mode using at least one of the cellular network, the non-cellular network, or a combination thereof based on the prediction.

Abstract: 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 registering with a first public land mobile network (PLMN) of a first network operator in response to detection of an interruption event associated with a second PLMN of a second network operator; determining that the interruption event has ended; and taking one or more actions to communicate with the second PLMN in response to the ending of the interruption event, wherein taking the one or more actions to communicate with the second PLMN is based on a constraint associated with access attempts to the second PLMN.

Abstract: Systems and techniques are described for processing media content, such as samples of sparse media content whose sample durations can be unknown at the time of decoding the samples, include obtaining, at a current time instance, a current fragment comprising at least a current time component. From the current time component, a modified duration is obtained for at least one media sample, the modified duration indicating a time duration by which a presentation of a previous media sample of a previous fragment is to be extended or reduced in relation to the current time instance. The at least one media sample is presented for a time duration based on the modified duration.

Abstract: A device for retrieving media 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 a media presentation indicating that container parsing of media data of a bitstream can be started at a resync point of a segment of a representation of the media presentation, the resync point being at a position other than a start of the segment and representing a point at which the container parsing of the media data of the bitstream can be started; use the manifest file to form a request to retrieve the media data of the representation starting at the resync point; send the request to initiate retrieval of the media data of the media presentation starting at the resync point; and present the retrieved media data.

Abstract: An example device for retrieving media data includes a memory configured to store media data; and one or more processors implemented in circuitry and configured to: receive data indicating a packet loss signaling mechanism, the packet loss signaling mechanism comprising at least one of that segments are sent in chunks, that transport object identifiers (TOIs) are sequential, or that a last packet of an object assigned to a TOI has a specific flag set in a header of the last packet, a base URL, a maximum latency, or a synchronization point in a file delivery header; detect loss of a packet using the at least one of the packet loss signaling mechanisms, the lost packet including missing media data; generate a byte range request for the missing media data using information of the file delivery header; and deliver a proper media object to a media application.
