Subslot physical downlink control channel monitoring and downlink preemption indication

摘要

Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive multiple physical downlink control channels (PDCCHs) in one or more slots along with data traffic, where one of the PDCCHs includes a downlink preemption indication (DLPI) signifying that a portion of the data traffic was preempted. In some cases, the UE may monitor, within a same slot, for both the data traffic and an additional PDCCH carrying the DLPI and then transmit, within the same slot, a feedback message based on attempting to decode the data traffic, taking into account the DLPI. Additionally, the UE may receive the data traffic via a first service, where the DLPI indicates a second service preempts the first service. In some cases, the DLPI may be transmitted based on the UE being capable of processing the data traffic and transmitting the feedback message within the same slot.
