METHOD AND APPARATUS FOR TRANSMITTING UPLINK SIGNAL OR UPLINK CHANNEL |
| 摘要 |
A method for transmitting a sounding reference signal (SRS) by a terminal in an environment in which a first carrier corresponding to a first serving cell and a second carrier corresponding to a second serving cell are aggregated is provided. The terminal receives first downlink control information (DCI) which is used for downlink scheduling and includes a first transmit power control (TPC) command through the first serving cell. The terminal controls transmit power of the SRS based on the first TPC command for transmit power control of the SRS. Next, the terminal transmits the SRS through the second serving cell using the controlled transmit power. |

1. A method for transmitting a sounding reference signal (SRS) by a terminal in an environment in which a first carrier corresponding to a first serving cell and a second carrier corresponding to a second serving cell are aggregated, the method comprising:
receiving first downlink control information (DCI) which is used for downlink scheduling and includes a first transmit power control (TPC) command through the first serving cell; controlling transmit power of the SRS based on the first TPC command for transmit power control of the SRS; and transmitting the SRS through the second serving cell using the controlled transmit power. |
