Method and device for transmitting uplink control channel in wireless communication system

A base station in a wireless communication system, the base station comprising:

• a transceiver;
• and
• a controller coupled to the transceiver,
• wherein the controller is configured to:
• transmit, to a user equipment (UE), configuration information for a physical uplink control channel (PUCCH), wherein the configuration information includes information configuring a single frequency network (SFN) scheme for simultaneous transmission across multi-panel (STxMP);
• transmit, to the UE, downlink control information (DCI) indicating a first transmission configuration indicator (TCI) state for a first PUCCH and a second TCI state for a second PUCCH, which are associated with the configuration information;
• and
• receive, from the UE, the first PUCCH based on the first TCI state and the second PUCCH based on the second TCI state, and
• wherein the first PUCCH and the second PUCCH are received based on the SFN scheme.

A method performed by a user equipment (UE) in a wireless communication system, the method comprising:

• receiving, from abase station, configuration information for a physical uplink control channel (PUCCH), wherein the configuration information includes information configuring a single frequency network (SFN) scheme for simultaneous transmission across multi-panel (STxMP):
• receiving, from the base station, downlink control information (DCI) indicating a first transmission configuration indicator (TCI) state for a first PUCCH and a second TCI state for a second PUCCH, which are associated with the configuration information;
• and
• transmitting, to the base station, the first PUCCH based on the first TCI state and the second PUCCH based on the second TCI state, and
• wherein the first PUCCH and the second PUCCH are transmitted based on the SFN scheme.
