    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a radio resource control (RRC) configuration that indicates that hybrid automatic repeat request (HARQ) feedback associated with a downlink HARQ process is disabled or enabled. The UE may receive a downlink control information (DCI) communication that overrides the RRC configuration. The UE may selectively transmit HARQ feedback, associated with the downlink HARQ process, for a downlink transmission based at least in part on the DCI communication. The UE may selectively initiate, based at least in part on selectively transmitting the HARQ feedback, physical downlink control channel (PDCCH) monitoring associated with the downlink HARQ process based at least in part on at least one of the RRC configuration or the DCI communication. Numerous other aspects are described.

    Abstract: Aspects are provided which improve RLM by allowing a UE to apply a longer monitoring window for out-of-sync determinations before the UE triggers an RLM timer for in-sync determinations. The UE first obtains a reference signal from a base station. The UE then determines multiple groups of consecutive out-of-sync indications in response to the reference signal. For example, the UE may perform looped out-of-sync monitoring, multi-cell or carrier monitoring, or a combination of such monitoring to determine the multiple groups of out-of-sync indications. Afterwards, the UE triggers the RLM timer in response to determining the multiple groups of consecutive out-of-sync indications. As a result, the UE may perform additional out-of-sync monitoring during RLM before proceeding with in-sync monitoring, thus allowing the UE to account for rapid BLER changes (ping-pong effects) that may occur in HAPS systems due to tropospheric turbulence and enabling more accurate RLM determinations and minimal RLF detections.

    Abstract: Methods, systems, and devices for wireless communication are described. In some wireless communications systems, a user equipment (UE) may support two or more uplink switching periods for transmit chain switching. The UE may transmit a UE capability message indicating the UE capability to support a first uplink switching period and a second uplink switching period for transmit chain switching. The first uplink switching period and the second uplink switching period may each correspond to different switching periods associated with configuration switches between different transmit chain configurations of the UE. The UE and a base station may select an uplink switching period from among the first uplink switching period and the second uplink switching period. The UE may transmit an uplink data message to the base station after a preparation time that is based on the uplink switching period.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may obtain a first value associated with transmitting an uplink communication that corresponds to a downlink communication received in a non-terrestrial network (NTN). The UE may compare the first value to a second value. The UE may selectively transmit the uplink communication, or selectively process the downlink communication, based at least in part on a result of comparing the first value to the second value. Numerous other aspects are described.
