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 configured to transmit control information in a wireless communication system, the terminal supporting transmission time intervals (TTIs) of different lengths, the terminal comprising:

• a receiver and a transmitter;
• at least one processor;
• and
• at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
• in a state in which (i) a scheduling request (SR) is prepared as part of a transmission of a first TTI-based physical uplink control channel (PUCCH), and (ii) the first TTI-based PUCCH overlaps in time with a second TTI-based PUCCH, where a number of symbols in the second TTI is less than a number of symbols in the first TTI:
• dropping the transmission of the first TTI-based PUCCH;
• determining whether to transmit the SR on the second TTI-based PUCCH based on whether the second TTI-based PUCCH coincides with a second TTI-based SR transmission instance;
• and
• based on the second TTI-based PUCCH not coinciding with the second TTI-based SR transmission instance, not transmitting the SR on the second TTI-based PUCCH.

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

• in a state in which (i) a scheduling request (SR) is prepared by the terminal as part of a transmission of a first TTI-based physical uplink control channel (PUCCH), and (ii) the first TTI-based PUCCH overlaps in time with a second TTI-based PUCCH, where a number of symbols in the second TTI is less than a number of symbols in the first TTI:
• not receiving transmission of the first TTI-based PUCCH;
• and
• based on the second TTI-based PUCCH not coinciding with a second TTI-based SR transmission instance, not receiving the SR on the second TTI-based PUCCH.

At least one non-transitory computer-readable storage medium encoded with at least one computer program comprising instructions that, when executed by at least one processor, perform operations of transmitting control information in a terminal supporting transmission time intervals (TTIs) of different lengths, the operations comprising:

• in a state in which (i) a scheduling request (SR) is prepared as part of a transmission of a first TTI-based physical uplink control channel (PUCCH), and (ii) the first TTI-based PUCCH overlaps in time with a second TTI-based PUCCH, where a number of symbols in the second TTI is less than a number of symbols in the first TTI:
• dropping the transmission of the first TTI-based PUCCH;
• determining whether to transmit the SR on the second TTI-based PUCCH based on whether the second TTI-based PUCCH coincides with a second TTI-based SR transmission instance;
• and
• based on the second TTI-based PUCCH not coinciding with the second TTI-based SR transmission instance, not transmitting the SR on the second TTI-based PUCCH via a transceiver of the terminal.
