1. A method of transmitting an uplink signal, which is transmitted by a user equipment in a wireless communication system, the method comprising:
- receiving, from a base station (BS), first downlink (DL) scheduling information on an initial transmission of a DL data via a DL control duration of a time unit # n, the time unit # n is configured based on one of a first time unit type and a second time unit type,wherein the first time unit type is used for configuring a time unit to contain the DL control duration, a guard period (GP), an uplink (UL) control duration, and a first DL data duration in time order, andwherein the second time unit type is used for configuring a time unit to contain the DL control duration, a second DL data duration, the GP, the UL control duration, and a third DL data duration in time order;
receiving, from the BS, the DL data via one of the first DL data duration and the second DL data duration of the time unit # n, based on a time unit type configured for the time unit # n,wherein the first time unit type is used when a specific time interval larger than a time interval between reception of the DL data via the first DL data duration and transmission of acknowledgement/negative acknowledgement (ACK/NACK) information is not required, andwherein the second time unit type is used when the specific time interval larger than the time interval between reception of the DL data via the first DL data duration and transmission of the ACK/NACK information is required;
transmitting, to the BS, the ACK/NACK information via an UL control duration of a time unit # n+1 in response to the DL data; and
receiving, from the BS, second DL scheduling information on retransmission of the DL data in a DL control duration of a time unit # n+2,wherein each of the time unit # n+1 and the time unit # n+2 is configured based on the first time unit type.
