Abstract: Enhancements to downlink feedback information (DFI) signaling is disclosed. According to the disclosed aspects, indications of DFI presence in downlink control information (DCI) messaging are provided that limit any increase to DCI overhead for uplink grants. In a first aspect, DFI presence may be signaled using unused or disallowed DCI variable states for indication of DFI presence. In another aspect, a separate bit may be added to a DCI message for indicating DFI presence. Additional aspects include repurposing DCI fields which are specific to cell radio network temporary identifier (C-RNTI)-based uplink grants, or may defining a new RNTI (e.g., DFI-RNTI) for indicating DFI presence. Further aspects may provide for radio resource control (RRC) signaling that configures which DCI variable state can be used to indicate DFI presence.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may indicate a UE capability for processing a physical downlink shared channel (PDSCH) and exclude an indication that the UE is capable of monitoring for more than one PDSCH transmission within a slot, per component carrier (CC). The UE may receive control information indicating a codebook configuration for hybrid automatic repeat request (HARQ) acknowledgment (ACK) and including a parameter that enables or disables such a capability for the UE to monitor for more than one PDSCH transmission within a slot. The UE may monitor for one or more downlink shared channel transmissions based on the control information and generate a HARQ-ACK codebook for the downlink transmissions, the codebook including feedback for one or more CCs based on the parameter in the control information.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network node, control resource set (CORESET) configuration information that is associated with one or more CORESETs. The UE may receive, from the network node and during a slot, a control channel communication via a CORESET of the one or more CORESETs, the CORESET being associated with a configuration that is based at least on part on a slot type associated with the slot, the slot type including at least one of a full-duplex slot type or a half-duplex slot type. Numerous other aspects are described.
