Method and device for transmsising and receiving physical uplink control channel between user equipment and base station in wireless communication system

A method for receiving an uplink control signal by a base station (BS) in a wireless communication system, the method comprising:

• transmitting, to a user equipment (UE), configuration information on presence or absence of frequency hopping for transmission of a physical uplink control channel (PUCCH) being composed of four or more symbols;
• and
• receiving, from the UE, the PUCCH including a demodulation reference signal (DM-RS) and uplink control information (UCI), which are time-division-multiplexed (TDMed) on different symbols according to symbol duration of the PUCCH and the presence or absence of the frequency hopping,
• wherein when the symbol duration of the PUCCH is equal to or less than X-symbol duration (where X is a natural number), resource locations to which the DM-RS and UCI are mapped are configured to vary according to the presence or absence of the frequency hopping, and
• wherein when the symbol duration of the PUCCH is more than the X-symbol duration (where X is the natural number), the resource locations to which the DM-RS and UCI are mapped are configured to be fixed regardless of the presence or absence of the frequency hopping.

A user equipment (UE) for transmitting a physical uplink control channel (PUCCH) to a base station (BS) in a wireless communication system, the UE comprising:

• a transmitter;
• a receiver;
• and
• a processor connected to the transmitter and receiver,
• wherein the processor is configured to:
• receive, from the BS, configuration information on presence or absence of frequency hopping for transmission of the PUCCH being composed of four or more symbols;
• determine resource locations of a demodulation reference signal (DM-RS) and uplink control information (UCI), which are included in the PUCCH and time-division-multiplexed (TDMed) on different symbols according to symbol duration of the PUCCH and the presence or absence of the frequency hopping;
• and
• transmit the PUCCH based on the determined resource locations of the DM-RS and UCI,
• wherein when the symbol duration of the PUCCH is equal to or less than X-symbol duration (where X is a natural number), the resource locations to which the DM-RS and UCI are mapped are configured to vary according to the presence or absence of the frequency hopping, and
• wherein when the symbol duration of the PUCCH is more than the X-symbol duration (where X is the natural number), the resource locations to which the DM-RS and UCI are mapped are configured to be fixed regardless of the presence or absence of the frequency hopping.
