In yet another example, if a HARQ feedback transmission and another transmission are scheduled on overlapping resources, a UE may be configured to multiplex bits of the HARQ feedback transmission and the other transmission or drop the other transmission.

Abstract: This disclosure provides systems, methods, and apparatus, including computer programs encoded on computer storage media, for multiple downlink control information (DCI) message handling for multiple control resource set (CORESET) groups. In one aspect, a user equipment (UE) may provide separate or joint feedback for data messages received from different CORESET groups. In some examples, the UE may be configured with code block group (CBG)-based transmissions for a component carrier (CC) or a CORESET group in a CC. If implementing a dynamic codebook, the UE may track separate transport block (TB)-based and CBG-based downlink assignment indexes (DAIs) for each CORESET group or may track joint TB-based and CBG-based DAIs across the set of CORESET groups to handle the CBG configuration. Additionally, or alternatively, if implementing a semi-static codebook, the UE may apply skipping rules across the set of CORESET groups or separately for each CORESET group to reduce signaling overhead.

A receiving device (such as user equipment (UE)) may receive a downlink grant including an indication to report channel state information. The receiving device may identify, based on the downlink grant, a number of channel state information processing units associated with reporting the channel state information, and may determine that an available number of channel state information processing units is less than the number of channel state information processing units. In some cases, the receiving device may allocate, based on the determining, a set of channel state information processing units including the available number of channel state information processing units and one or more additional channel state information processing units. The receiving device may then transmit the channel state information report based on the set of channel state information processing units.
