User equipment and method
Abstract:
A user equipment according to an embodiment comprises a processor and a memory coupled to the processor. The processor is configured to receive a first control information from a base station, the first control information designating a first time region on which a first Hybrid Automatic Repeat Request-Acknowledgement (HARQ-ACK) to be transmitted, the first HARQ-ACK corresponding to a first data transmitted on a first Physical Downlink Shared Channel (PDSCH) in which a transmission time interval is shorten than one subframe, the first time region being shorten than one subframe. The processor is configured to attempt to receive a second data transmitted on a second PDSCH in which a transmission time interval is one subframe. The processor is configured to transmit a second HARQ-ACK corresponding to the second data on the first time region.
