1. A terminal comprising:
a receiver that receives a single medium access control control element (MAC CE) to activate first spatial relation information for a first transmission and reception point (TRP) and to activate second spatial relation information for a second TRP; and
a processor that applies the first spatial relation information to a first physical uplink control channel (PUCCH) to be transmitted to the first TRP, and applies the second spatial relation information to a second PUCCH to be transmitted to the second TRP,
wherein the processor:
if the terminal is provided with a Radio Resource Control (RRC) signaling, controls to transmit the first PUCCH and the second PUCCH in a single slot, and
if the terminal is not provided with the RRC signaling, controls to transmit the first PUCCH and the second PUCCH each in different slots, and
wherein a first Hybrid Automatic Repeat reQuest ACKnowledgement (HARQ-ACK) transmitted to the first TRP and a second HARQ-ACK transmitted to the second TRP have a same content.
