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: This disclosure provides systems, methods and apparatuses for network selection in a service interruption scenario. In some aspects, a user equipment (UE) may receive an indication that a condition is associated with a first network to which the UE is registered. The UE may perform a network selection procedure based at least in part on receiving the indication. In some aspects, the network selection procedure includes a legacy network selection procedure and is associated with roaming information received by or configured on the UE. In some aspects, a UE may receive an indication that a condition is associated with a network to which the UE is registered. The UE may provide, for display and based at least in part on receiving the indication, network selection information associated with a set of networks. The network selection information may include an indication that a given network accommodates inbound roamers.

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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network device, a UE route selection policy (URSP) rule that indicates a preference for a multi-access protocol data unit (PDU) session and a preferred quantity and preferred types of access links for the multi-access PDU session. The UE may establish the multi-access PDU session using the preferred quantity and the preferred types of access links indicated by the URSP rule. Numerous other aspects are described.

Abstract: Techniques for managing access combinations for multiple access protocol data unit (PDU) sessions are described. A communication device may receive control signaling indicating a configuration for a multiple access PDU session associated with a plurality of access links. The plurality of access links may be associated with a first type of access, a second type of access, or a combination thereof. The communication device may select a mode for allocation of a data flow associated with the multiple access PDU session to the plurality of access links based at least in part on the received control signaling. The communication device may allocate the data flow associated with the multiple access PDU session to the plurality of access links based at least in part on the selected mode, and transmit the allocated data flow over the plurality of access links associated with the two types of access.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network node (e.g., a session management function (SMF)) may receive policy and charging control (PCC) rules that include control information associated with a non-integrated aggregation (NIA) protocol data unit (PDU) session requested by a user equipment (UE). The SMF may communicate, to the UE, one or more access traffic steering, switching, and splitting (ATSSS) rules derived from the PCC rules, wherein the one or more ATSSS rules are for controlling traffic steering, switching, and splitting associated with the NIA PDU session in an uplink direction. The network node may communicate, to a user plane function (UPF), N4 interface rules derived from the PCC rules, wherein the N4 interface rules are for controlling traffic steering, switching, and splitting associated with the NIA PDU session in a downlink direction. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques support authentication and authorization (AA) for various services provided by a network and supported by a user equipment (UE). A UE may transmit a container to a first network entity requesting AA for a first service. The container may include an indicator of the first service, and the indicator may indicate or distinguish the first service from multiple services. The first network entity may query a third network entity based on the indicator of the first service to discover a second network entity supporting AA for the first service. The first network entity may then transmit an indicator of the first service to the second network entity, and the second network entity may select a fourth network entity supporting AA for the first service.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network entity may receive policy and charging control (PCC) rules that indicate that a multi-access (MA) protocol data unit (PDU) session is to be established with a redundant steering mode. The network entity may transmit N4 interface rules that indicate the redundant steering mode and parameters for the MA PDU session, such as an uplink duplication factor, a downlink duplication factor, an uplink redundant bitrate, a downlink redundant bitrate, or an access path to duplicate. The network entity may transmit access traffic steering, switching, and splitting (ATSSS) rules that indicate, for the MA PDU session, an indication to use the redundant steering mode and the parameters. Numerous other aspects are described.
