Method for transmitting and receiving scheduling request between terminal and base station in wireless communication system and device for supporting same

A method of receiving a scheduling request (SR) from a user equipment (UE) by a base station (BS) in a wireless communication system, the method comprising:

• transmitting, to the UE, (i) first information related to first physical uplink control channel (PUCCH) resources for a plurality of SRs, and (ii) second information related to a second PUCCH resource for hybrid automatic repeat request acknowledgement (HARQ-ACK) information, wherein at least one of the first PUCCH resources overlaps in time with the second PUCCH resource;
• and
• receiving a signal comprising (i) the HARQ-ACK information, and (ii) bit information related to the plurality of SRs, which is appended to the HARQ-ACK information,
• wherein, in a state in which at least one of the plurality of SRs is a positive SR, and based on the HARQ-ACK information being larger than 2 bits:
• the bit information related to the plurality of SRs is configured to identify one SR from among the plurality of SRs.

A user equipment (UE) configured to transmit a scheduling request (SR) to a base station (BS) in a wireless communication system, the UE comprising:

• a receiver;
• 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:
• receiving, from the BS, (i) first information related to first physical uplink control channel (PUCCH) resources for a plurality of SRs, and (ii) second information related to a second PUCCH resource for hybrid automatic repeat request acknowledgement (HARQ-ACK) information, wherein at least one of the first PUCCH resources overlaps in time with the second PUCCH resource;
• and
• transmitting a signal comprising (i) the HARQ-ACK information, and (ii) bit information related to the plurality of SRs, which is appended to the HARQ-ACK information,
• wherein, in a state in which at least one of the plurality of SRs is a positive SR, and based on the HARQ-ACK information being larger than 2 bits:
• the bit information related to the plurality of SRs is configured to identify one SR from among the plurality of SRs.
