9. A user equipment for receiving a downlink channel in a wireless communication system, the user equipment comprising:a transceiver;
a processor; and
a computer memory that is operably connectable to the processor and that has stored thereon instructions which, when executed, cause the processor to perform operations comprising:
receiving, via the transceiver, a first physical downlink control channel (PDCCH) associated with a first physical downlink shared channel (PDSCH) of a first transmission time interval (TTI) and a second PDCCH associated with a second PDSCH of a second TTI configured in the first TTI; and
decode the second PDSCH not the first PDSCH in the first TTI, in the state in which the user equipment is unable to decode the first PDSCH and the second PDSCH in a same TTI,
wherein the first TTI has a first TTI length in a time domain, and
wherein the second TTI has a second TTI length shorter than the first TTI length in the time domain.
