Abstract: An example device for presenting media data includes a memory configured to store media data; and one or more processors implemented in circuitry and configured to: receive a first set of media data of a media bitstream; in response to determining that a second set of media data of the media bitstream following the first set of media data will not be received within a period of time, predictively generate replacement media data for the second set of media data using at least a subset of the first set of media data; and present the first set of media data and the replacement media data.

Abstract: Non-terrestrial networks (NTNs) may establish uplink (UL) and downlink (DL) radio frame timing structures to efficiently account for propagation delay and propagation delay variation associated with communications in the NTN. NTNs may manage (synchronize) radio frame timing structures of base stations (e.g., satellites) and user equipment (UEs) in the NTN. Further, UEs may determine timing advance (TA) values to be applied to UL transmissions based on their respective scheduling offset (e.g., offset in UL and DL radio frame timing structures), as well as based on propagation delay or round trip time (RTT). As such, served UEs may determine UL timing such that UL transmissions from the UEs to a satellite arrives at the satellite in a time synchronized manner. In other cases, a satellite may determine UL timing, based on reception timing, such that various UEs in the NTN may implement uniform UL and DL radio frame timing structures.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may release a connection with a first network entity and determine a first virtual coverage area of the UE based on a geographic location of the UE associated with the release of the connection. The UE may obtain a message that includes area information. The area information may be indicative of one or more second virtual coverage areas, which the UE may use in determining whether to monitor for a paging early indication (PEI). Based on the first virtual coverage area and the one or more second virtual coverage areas may monitor for a paging message, such as the PEI or downlink control information (DCI) associated with a paging occasion.

Abstract: Methods, systems, and devices for wireless communications are described. The method may include establishing a connection between the UE and a network node of a non-terrestrial network, identifying, based on a synchronization failure event and while the UE is in a connected mode in accordance with establishing the connection, that a location failure condition has occurred for the connection, and performing, at least in part in response to the location failure condition, one or more actions of a location failure recovery procedure to restore a synchronization associated with the connection.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a time-domain resource for an uplink transmission. The UE may determine a time period, during which the UE is to refrain from monitoring for downlink communications, based at least in part on the time-domain resource for the uplink transmission and at least one of a first time offset associated with a difference in starting time between an uplink radio frame and a corresponding downlink radio frame at the UE, a second time offset associated with an uplink-downlink timing interaction for the UE, or a network-indicated offset. Numerous other aspects are provided.

Abstract: Some techniques and apparatuses described herein enable a user equipment (UE) to autonomously modify one or more transmission parameters, other than a transmit power, for uplink communications after detecting a change in pathloss. The UE may modify the one or more transmission parameters without receiving instructions from a base station, such as in downlink control information, with updated value(s) for the one or more transmission parameters. As a result, the UE and the base station avoid the round trip delay that would otherwise be required to modify the transmission parameter(s) and perform link adaptation. Some techniques and apparatuses described herein apply to non-terrestrial networks with a large round trip delay. Other aspects are described.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for wireless communication via a non-terrestrial network (NTN). In one aspect, a method for wireless communication includes initiating, by a user equipment (UE), a registration process with a network entity of an NTN to access the NTN. The method also includes transmitting, by the UE to the network entity, UE capability information of the UE. The method further includes receiving, by the UE from the network entity, a handover command, the handover command comprising a handover time indicator associated with a target handover time for the UE to perform a handover operation from a first beam to a second beam. Other aspects and features are also claimed and described.

Abstract: Methods, systems, and devices for wireless communication are described. A communication device, such as a user equipment (UE) may identify information for transmitting to a base station of a non-terrestrial network. The UE may identify that one or more resources allocated for transmitting the information are available based at least in part on identifying the information. The one or more resources include one or more types of uplink resources including physical random access channel (PRACH) resources or physical uplink shared channel (PUSCH) resources for the random access procedure, a PUSCH for a scheduling request (SR), or a physical uplink control channel (PUCCH) for a configured grant, or a combination thereof. As a result, the UE may transmit, to the base station, a message over the one or more resources allocated for the information based at least in part on identifying the one or more resources.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit buffer status information using configured periodic uplink resources. For example, a base station may configure dedicated periodic uplink resources, periodic random access resources, or periodic uplink grants to enable the UE to transmit the buffer status information. In some cases, the periodic random access resources may enable the UE to transmit a first message of a four-step or two-step random access procedure to indicate the buffer status information. Additionally or alternatively, the base station may configure a type of scheduling request for the UE to transmit that can indicate whether a buffer size falls within a range, where the base station then can more accurately allocate uplink resources in an uplink grant for the UE to transmit the uplink data based on receiving this type of scheduling request.
