Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive an indication of a waveform threshold for selecting a waveform type for transmitting a message of a random access procedure. The UE may select the waveform type for the message of the random access procedure based on the waveform threshold and a value associated with a power of signals received at the UE. The UE may transmit the message of the random access procedure to a network entity according to the waveform type selected for the message.

Abstract: A UE may receive, from at least one cell via at least one bit in a MIB or a SIB, a barring indication based on a supported network of the at least one cell and a supported network of the UE. The supported network of the at least one cell may correspond to a TN or an NTN, and the supported network of the UE may correspond to a TN or an NTN. The UE may skip, based on the received barring indication, a selection of the at least one cell for communication. Accordingly, the UE may not camp on the at least one cell. The barring indication for NTN-supporting UEs and for TN-supporting UEs may be separately indicated via the MIB or the SIB.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a report of a maximum transport block size supported by the UE for if hybrid automatic repeat request (HARQ) feedback is enabled and a maximum transport block size for is HARQ is disabled. The UE may receive, based at least in part on transmitting the report, one or more transport blocks that have a transport block size that does not exceed the maximum transport block sizes supported by the UE. In some aspects, the UE may receive an indication of a length of a span for receiving a set of bits from channel encoder output for a transport block or a redundancy version of a transport block. Numerous other aspects are provided.

Abstract: Various aspects relate to adjusting communication timing in response to a switch from one feeder link to another feeder link in a non-terrestrial network. For example, when a satellite moves out of the coverage area of a first ground network entity (or if the first ground network entity is turned off), the satellite switches to a second ground network entity. The resulting switch from a first feeder link for the first ground network entity to a second feeder link for the second ground network entity may cause a timing glitch that adversely affects the UEs under the coverage of the satellite. The disclosure relates in some aspects to sending an indication of the switch and/or a common timing adjust command to all of the UEs affected by the feeder link switch.

Abstract: Methods, systems, and devices for wireless communications are described in which random access preambles may be designed to provide for relatively low inter-carrier interference (ICI) of adjacent available frequency resources in a non-terrestrial network (NTN). Random access preambles for NTN random access requests may be selected from a first set of random access preambles that are different from a second set of random access preambles for terrestrial random access requests. The first set of random access preambles may be a subset of the second set of random access preambles. The first set of random access preambles may be provided for contention-based random access (CBRA) and contention-free random access (CFRA) preambles may be configured by a base station from random access preambles that correspond to or are different from the second set of random access preambles.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a radio resource control (RRC) reconfiguration message from a base station including a configuration for communicating with the base station, and the base station may transmit an RRC reconfiguration complete message to the base station (e.g., in response to the RRC reconfiguration message). The UE may then apply the configuration in the RRC reconfiguration message for communicating with the base station after transmitting the RRC reconfiguration complete message. That is, the UE may delay application of the configuration in the RRC reconfiguration message until after the UE transmits the RRC reconfiguration complete message. Using these techniques, ambiguity between the base station and the UE on when the configuration is applied by the UE may be minimized, resulting in improved throughput and reduced latency in a wireless communications system.

Abstract: An example first client device for transmitting augmented reality (AR) media data includes a memory configured to store media data including voice data and augmented reality (AR) data; and one or more processors implemented in circuitry and configured to: participate in a voice call session with a second client device; receive data indicating that an AR session is to be initiated in addition to the voice call session from the second client device; receive data to initiate the AR session; and participate in the AR session with the second client device using the data to initiate the AR session.

Abstract: Methods, systems, and devices for wireless communications are described. A network node and a user equipment (UE) may establish a connection between the UE and the network node of a non-terrestrial network. The UE may receive, from the network node and based on a type of orbit around Earth of the network node, a first value or the first value and a second value associated with a position or a velocity of the network node relative to a terrestrial-based reference. The UE and the network node may communicate based on the position or the velocity of the network node, or both. In some cases, the position or the velocity of the network node is based on an altitude of the network node, the first value, the second value, and a third value.

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: Methods, systems, and devices for wireless communication at a user equipment (UE) are described. A UE may receive a first timing information associated with a first cell and a second timing information associated with a second cell. In some examples, the first cell may be associated with a first non-terrestrial device and the second cell may be associated with a second non-terrestrial device. In some examples, the first cell and the second cell may be associated with a common non-terrestrial device. The UE may calculate a propagation delay in accordance with a type of delay measurement and select a cell based on the propagation delay. The UE may calculate a propagation delay in accordance with a type of delay measurement and reselect a cell based on the propagation delay. In some examples, the propagation delay may be based on the first timing information and the second timing information.
