    Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to mechanisms for using block acknowledgments to acknowledge semi-persistently scheduled (SPS) occasions from multiple SPS configurations. An example method generally includes identifying a slot or subslot scheduled for reporting acknowledgment feedback for an SPS physical downlink shared channel (PDSCH). The method identifies that one or more symbols of the identified slot or subslot that are scheduled to transmit a physical uplink control channel (PUCCH) containing the acknowledgment feedback are semi-static flexible symbols. The method further monitors for a dynamic slot format indicator (SFI) dynamically configuring one or more of the semi-static flexible symbols of the slot or subslot as downlink, uplink, or flexible. The method then decides whether to report the acknowledgment feedback in the scheduled slot or subslot, in a subsequent slot or subslot, or both, based on the monitoring.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine that a first timing value, received in first downlink control information (DCI) that schedules a first sidelink communication, for indicating a time duration between receiving the first DCI and transmitting first sidelink hybrid automatic repeat request (HARQ) feedback for the first sidelink communication is an inapplicable value. The UE may transmit the first sidelink HARQ feedback in a sidelink HARQ acknowledgment codebook based at least in part on receiving a second DCI that includes a second timing value that is a valid numerical value. Numerous other aspects are provided.

    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of a timing advance (TA) offset value for a high frequency range operating band. The UE may communicate in the high frequency range operating band, in accordance with the TA offset value. In some aspects, a UE may receive an indication of at least one of a TA offset value associated with a full-duplex communication mode of a base station or a TA offset value associated with a half-duplex communication mode of a base station. The UE may communicate, with the base station, in accordance with at least one of the TA offset value associated with the full-duplex communication mode of the base station or the TA offset value associated with the half-duplex communication mode of the base station. Numerous other aspects are provided.

    Abstract: Techniques providing opportunistic frequency switching for frame based equipment (FBE), such as may be configured to minimize opportunistic frequency switching delay in FBE new radio (NR) unlicensed (NR-U) networks and/or to provide frequency diversity FBE access based on offset sequences of medium sensing occasions for the carrier frequencies are disclosed. Within the FBE mode network, a base station may configure a pattern of sensing locations in each frame for each frequency transmission unit of the plurality of frequency transmission units, wherein an inter-unit delay of sensing locations between a first frequency transmission unit and a next adjacent frequency transmission unit and between a last frequency transmission unit and the first frequency transmission unit is a fixed duration. Opportunistic frequency switching of embodiments may utilize the medium sensing locations for opportunistically switching between a sequence of the frequency transmission units for implementing frequency diversity FBE access.
