Method for transmitting and receiving uplink control channel and device therefor

A method for transmitting an uplink control channel, performed in a terminal, the method comprising:

• receiving, from a base station, information on a period of repeated transmissions and a number of repeated transmissions for a scheduling request (SR);
• and
• repeatedly transmitting an uplink control channel including the SR by the number of repeated transmissions according to the period of repeated transmissions,
• wherein the uplink control channel including the SR is transmitted once or two times in a slot.

A method for transmitting an uplink control channel, performed in a terminal, the method comprising:

• receiving, from a base station, information on a period of repeated transmissions and a number of repeated transmissions for a first scheduling request (SR) and information on a period of repeated transmissions and a number of repeated transmissions for a second SR;
• comparing a priority of the first SR with a priority of the second SR, when a part or all of symbols of a first uplink control channel including the first SR according to the period of repeated transmissions for the first SR overlap with a part or all of symbols of a second uplink control channel including the second SR according to the period of repeated transmissions for the second SR;
• and
• transmitting the second uplink control channel without transmitting a part or all of the symbols of the first uplink control channel, when the priority of the second SR is higher than the priority of the first SR,
• wherein each of the uplink control channel including the first SR and the uplink control channel including the second SR is transmitted once or two times in a slot.
