    Abstract: Techniques for physical uplink control channel (PUCCH) operation with multiple transmission and reception point (multi-TRP) are disclosed. In some embodiments, determining PUCCH transmission repetition may include determining that an original PUCCH transmission overlaps a slot boundary between a first slot for PUCCH transmission and a second slot for PUCCH transmission, and configuring a PUCCH repetition of the original PUCCH transmission. The PUCCH repetition may include one or more symbols of the original PUCCH transmission and may be located in one or more slots other than the first slot and the second slot. The PUCCH repetition may be configured by a downlink control information (DCI) configuration that includes a physical downlink shared channel to hybrid automatic repeat request acknowledgement feedback (PDSCH-to-HARQ_feedback) timing indicator, a PUCCH repetition number field that configures a number of transmissions of the PUCCH repetition, or a PUCCH resource indicator field that configures a number of transmissions of the PUCCH repetition.

    Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform multiple TTI PUSCH transmissions in a wireless communication system as well as code block groups (CBGs) based retransmissions operations. A UE may perform radio resource control (RRC) signaling with a network entity to configure a data structure that may include one or more sets of physical uplink shared channel (PUSCH) transmission configurations, where each set of PUSCH transmission configurations span multiple TTIs. The wireless device may be configured to receive, from the network entity, a downlink control information (DCI) message that may include a time domain resource assignment field (TDRA) that may indicate a set of PUSCH transmission configurations included in the data structure. The wireless device may perform PUSCH transmissions spanning multiple TTIs according to the indicated set of PUSCH transmission configurations over an unlicensed band.
