Method for transmitting and receiving multiplexed uplink control channel and localized sounding reference symbol and device therefor

A user equipment (UE) for transmitting an uplink control channel and a localized Sounding Reference Symbol (SRS) which are multiplexed, the user equipment comprising:

• a transmitter;
• and
• a processor,
• wherein the processor is configured to control the transmitter to:
• transmit the uplink control channel by segmenting the uplink control channel into a plurality of uplink control channel sub-blocks in a frequency domain, when a frequency band length of the localized SRS is equal to or smaller than a length of a coherent bandwidth;
• and
• transmit the segmented uplink control channel sub-blocks in one symbol by frequency division multiplexing with at least one localized SRS.

A base station (BS) for receiving an uplink control channel and a localized Sounding Reference Symbol (SRS) which are multiplexed, the base station comprising:

• a receiver;
• and
• a processor,
• wherein the processor is configured to control the receiver to:
• receive the uplink control channel that is segmented into a plurality of uplink control channel sub-blocks in a frequency domain, when a frequency band length of the localized SRS is equal to or smaller than a length of a coherent bandwidth;
• and
• receive the segmented uplink control channel sub-blocks and at least one localized SRS in one symbol based on a frequency division multiplexing scheme.
