Method and apparatus for transmitting or receiving uplink signal for terminal supporting multiple ttis, multiple subcarrier spacings, or multiple processing times in wireless communication system

A terminal for transmitting control information in a wireless communication system, the terminal supporting a plurality of transmission time interval (TTI) lengths and, the terminal comprising:

• a receiver and a transmitter;
• and
• a processor that controls the receiver and the transmitter,
• wherein the processor receives downlink data, transmits a hybrid automatic retransmission request-acknowledgement/non-acknowledgement (HARQ-ACK) on a first physical uplink control channel (PUCCH), when transmission timings of the first PUCCH for transmitting the HARQ-ACK that corresponds to the downlink data and a second PUCCH for transmitting a scheduling request (SR) overlap with each other,
• wherein the first PUCCH includes a smaller number of symbols than the second PUCCH and
• wherein when a timing where the first PUCCH and the second PUCCH overlap with each other does not correspond to a SR transmission timing of the first PUCCH, the SR is not transmitted.

A method of receiving control information that is transmitted by a terminal supporting a plurality of transmission time interval (TTI) lengths in a wireless communication system, the method being performed by a base station (BS) and comprising:

• transmitting downlink data;
• and
• receiving a hybrid automatic retransmission request-acknowledgement/non-acknowledgement (HARQ-ACK) on a first physical uplink control channel (PUCCH), when transmission timings of the first PUCCH for transmitting the HARQ-ACK that corresponds to the downlink data and a second PUCCH for transmitting a scheduling request (SR) overlap with each other,
• wherein the first PUCCH includes a smaller number of symbols than the second PUCCH and
• wherein when a timing where the first PUCCH and the second PUCCH overlap with each other does not correspond to a SR transmission timing of the first PUCCH, the SR is not received.
