What is claimed is:1. A method for a terminal, the method comprising:receiving a radio resource control (RRC) message including a plurality of identity information related to uplink (UL) transmission, the plurality of identity information including an indication indicating a type of a reference signal related to the UL transmission and an index of the reference signal; receiving, from a base station, a medium access control-control element (MAC-CE) including information associated with a physical uplink control channel (PUCCH) and the reference signal; selecting a beam for the UL transmission based on the indication; and transmitting an UL signal based on the selected beam, wherein one identity information among the plurality of identity information is indicated by the MAC CE, and wherein the UL signal corresponds to control information transmitted on the PUCCH. 2. The method of claim 1 , wherein the type indicates at least one type of: a channel state information-reference signal (CRI-RS), a synchronization signal block (SSB), or a sounding reference signal (SRS). 3. The method of claim 1 , wherein the index comprises at least one of: a channel state information-reference signal (CSI-RS) resource identity information, synchronization signal block (SSB) identity information, or sounding reference signal (SRS) resource identity information. 4. A terminal comprising:a transceiver; and at least one processor configured to:receive, from a base station via the transceiver, a radio resource control (RRC) message including a plurality of identity information related to uplink (UL) transmission, the plurality of identity information including an indication indicating a type of a reference signal related to the UL transmission and an index of the reference signal, receive, from the base station via the transceiver, a medium access control-control element (MAC-CE) including information associated with a physical uplink control channel (PUCCH) and the reference signal, select a beam for the UL transmission based on the indication, and transmit, via the transceiver, an UL signal based on the selected beam, wherein one identity information among the plurality of identity information is indicated by the MAC CE, and wherein the UL signal correspond to control information transmitted on the PUCCH. 5. The terminal of claim 4 , wherein the type indicates at least one type of: a channel state information-reference signal (CRI-RS), a synchronization signal block (SSB), or a sounding reference signal (SRS). 6. The terminal of claim 4 , wherein the index comprises at least one of: a channel state information-reference signal (CSI-RS) resource identity information, synchronization signal block (SSB) identity information, or sounding reference signal (SRS) resource identity information. 7. A method for a base station, the method comprising:transmitting, to a terminal, a radio resource control (RRC) message including a plurality of identity information related to uplink (UL) transmission, the plurality of identity information including an indication indicating a type of reference signal related to the UL transmission and an index of the reference signal; transmitting, to the terminal, a medium access control-control element (MAC-CE) including information associated with a physical uplink control channel (PUCCH) and the reference signal; selecting a beam for UL reception based on the indication; and receiving an UL signal from the terminal based on the selected beam, wherein one identity information among the plurality of identity information is indicated by the MAC CE, and wherein the UL signal corresponds to control information transmitted on the PUCCH. 8. The method of claim 7 , wherein the type indicates at least one type of: a channel state information-reference signal (CRI-RS), a synchronization signal block (SSB), or a sounding reference signal (SRS). 9. The method of claim 7 , wherein the index comprises at least one of: a channel state information-reference signal (CSI-RS) resource identity information, synchronization signal block (SSB) identity information, or sounding reference signal (SRS) resource identity information. 10. A base station, comprising:a transceiver; and at least one processor configured to:transmit, to a terminal via the transceiver, a radio resource control (RRC) message including a plurality of identity information related to uplink (UL) transmission, the plurality of identity information including an indication indicating a type of reference signal related to the UL transmission and an index of the reference signal, transmit, to the terminal via the transceiver, a medium access control-control element (MAC-CE) including information associated with a physical uplink control channel (PUCCH) and the reference signal, select a beam for UL reception based on the indication, and receive, via the transceiver, an UL signal from the terminal based on the selected beam, wherein one identity information among the plurality of identity information is indicated by the MAC CE, and wherein the UL signal correspond to control information transmitted on the PUCCH. 11.
