receiving, from a base station, radio resource control (RRC) information on a list of physical uplink control channel (PUCCH) spatial relation configurations used to configure spatial settings for a PUCCH transmission; and
based on a PUCCH resource used for repetitions of the PUCCH transmission including first and second spatial settings and a number of slots for the repetitions of the PUCCH transmission being configured as 2, transmitting, to the base station, an uplink control signal on the PUCCH resource using the first and second spatial settings for first and second repetitions of the PUCCH transmission, respectively.

2. The method of claim 1 , further comprising receiving, from the base station, a medium access control (MAC) control element (CE) activating two PUCCH spatial relation configurations associated respectively with the first and second spatial settings among the list of PUCCH spatial relation configurations.

3. The method of claim 1 , further comprising receiving, from the base station, downlink control information (DCI) indicating the PUCCH resource.

4. The method of claim 1 , wherein each PUCCH spatial relation configuration of the list of PUCCH spatial relation configurations is associated with a synchronization signal block (SSB), a channel state information-reference signal (CSI-RS), or a sounding reference signal (SRS).

5. The method of claim 1 , further comprising receiving, from the base station, a downlink signal on a physical downlink shared channel (PDSCH),
wherein the uplink control signal includes feedback information for the downlink signal.
