Method for terminal for carrying out uplink communication in wireless communication system, and terminal using method
Provided are a method for a terminal for carrying out uplink communication in a wireless communication system, and an apparatus using the method. The method receives an uplink communication-related parameter independently configured for each analog beam, and carries out the uplink communication on the basis of the parameter. If the uplink communication is carried out using a particular analog beam, then an uplink communication-related parameter configured on the particular analog beam is applied to the uplink communication.
1. A method of performing physical uplink control channel (PUCCH) transmission to a base station (BS) by a user equipment (UE) in a wireless communication system, the method comprising:
receiving, from the BS, a plurality of settings for the PUCCH transmission, wherein each of the plurality of settings includes i) PUCCH power control parameters and ii) information for one of a plurality of reference signals;
receiving, from the BS, a signal informing of a setting among the plurality of settings for the PUCCH transmission;
determining a transmission power for the PUCCH transmission based on at least one power control parameter included in the setting; and
performing the PUCCH transmission using the transmission power,
wherein the UE transmits the PUCCH using a beam based on the information for one of a plurality of reference signals.
2. The method of claim 1 , wherein the setting comprises information related to an identity of a reference signal among the plurality of reference signals.
3. The method of claim 1 , wherein the at least one power control parameter comprises an open-loop power control parameter.
4. The method of claim 1 , wherein the at least one power control parameter comprises information for a path loss.
5. The method of claim 1 , wherein the at least one power control parameter comprises information for a transmit power control (TPC) accumulation operation.
6. A user equipment (UE) configured to perform physical uplink control channel (PUCCH) transmission to a base station (BS) in a wireless communication system, the UE comprising:
at least one transceiver;
at least one processor; and
at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed, cause the at least one processor to perform operations comprising:
receiving, from the BS, a plurality of settings for the PUCCH transmission, wherein each of the plurality of settings includes i) PUCCH power control parameters and ii) information for one of a plurality of reference signals;
receiving, from the BS, a signal informing of a setting among the plurality of settings for the PUCCH transmission;
determining a transmission power for the PUCCH transmission based on at least one power control parameter included in the setting; and
performing the PUCCH transmission using the transmission power,
wherein the UE transmits the PUCCH using a beam based on the information for one of a plurality of reference signals.
7. The UE of claim 6 , wherein the setting comprises information related to an identity of a reference signal among the plurality of reference signals.
8. The UE of claim 6 , wherein the at least one power control parameter comprises an open-loop power control parameter.
9. The UE of claim 6 , wherein the at least one power control parameter comprises information for a path loss.
10. The UE of claim 6 , wherein the at least one power control parameter comprises information for a transmit power control (TPC) accumulation operation.
11. A method of receiving a physical uplink control channel (PUCCH) by a base station (BS) in a wireless communication system, the method comprising:
transmitting, to a user equipment (UE), a plurality of settings for a PUCCH transmission by the UE to the B S, wherein each of the plurality of settings includes i) PUCCH power control parameters and ii) information for one of a plurality of reference signals;
transmitting, to the UE, a signal informing of a setting among the plurality of settings for the PUCCH transmission; and
receiving, from the UE, the PUCCH of which transmission power is determined based on at least one power control parameter included in the setting,
wherein the UE transmits the PUCCH using a beam based on the information for one of a plurality of reference signals.
12. The method of claim 11 , wherein the setting comprises information related to an identity of a reference signal among the plurality of reference signals.
13. The method of claim 11 , wherein the at least one power control parameter comprises an open-loop power control parameter.
14. The method of claim 11 , wherein the at least one power control parameter comprises information for a path loss.
15. The method of claim 11 , wherein the at least one power control parameter comprises information for a transmit power control (TPC) accumulation operation.
