    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus at a user equipment (UE) in a non-terrestrial network (NTN) are provided. The UE may be configured to receive one or more timing advance (TA) commands from an NTN. In response to a transmission timing error between a transmission TA of the UE and a reference timing exceeding a threshold, the UE may be configured to transmit an uplink transmission with a timing change having a total timing adjustment, other than a propagation delay adjustment due to an NTN node position update and a network-controlled common TA value, that satisfies one or more threshold requirements.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, an uplink grant for a physical uplink shared channel (PUSCH) that is to overlap in time with a physical uplink control channel (PUCCH) used for hybrid automatic repeat request (HARQ) feedback for at least multicast, the uplink grant including a downlink assignment index (UL-DAI) indication that indicates at least one of: whether the HARQ feedback of the PUCCH is to be multiplexed on the PUSCH, or a size for the HARQ feedback. The apparatus may communicate, with the network entity, in accordance with the UL-DAI indication. Numerous other aspects are described.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network entity, configuration information associated with a semi-static hybrid automatic repeat request (HARQ) feedback codebook for multicast messages. The UE may receive, from the network entity, a physical downlink control channel (PDCCH) message, associated with a radio network temporary identifier (RNTI), scheduling one or more multicast physical downlink shared channel (PDSCH) messages. The UE may transmit, to the network entity, one or more fallback HARQ feedback indications, associated with the one or more multicast PDSCH messages, in lieu of transmitting the semi-static HARQ feedback codebook, in accordance with the configuration information and associated with at least one of the RNTI or a feedback configuration associated with the RNTI. Numerous other aspects are provided.

    Abstract: Methods, systems, and devices for wireless communications are described Generally, the described techniques provide for a user equipment (UE) to perform a beam switching operation from a current beam to a target beam based on a beam switching duration. The UE may transmit a capability report that may include an antenna pointing capability, a list of one or more detailed capabilities, or both to another device, such as a network entity (e.g., a satellite). The UE may perform the beam switching operation based on the capability report. The UE may perform a random access procedure as part of a change of association operation. The UE may receive a control message from the other device, which may be the network entity, that includes an identity of a target network entity, one or more resources for the random access procedure, an indication of the beam switching duration, or any combination.
