1. One or more non-transitory computer-readable media having instructions that, when executed, cause processing circuitry; to:
process downlink control information (DCI) that includes a transmission configuration indicator (TCI) indication;
determine that the DCI does not schedule a data transmission; and
generate hybrid automatic repeat request-acknowledgment (HARQ-ACK) feedback corresponding to the DCI,
wherein to determine that the DCI does not schedule a data transmission, the processing circuitry is to:
determine a type of a radio network temporary identifier (RNTI) used to scramble cyclic redundancy check (CRC) bits of the DCI and determine that the DCI does not schedule a data transmission based on the type of the RNTI; or
detect a value of a field of the DCI and determine that the DCI does not schedule a data transmission based on the value.
