APERIODIC TRANSMISSION METHOD AND APPARATUS FOR SOUNDING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM |
| 摘要 |
A method for transmitting, by a user equipment (UE), an aperiodic sounding reference signal (SRS) in a wireless communication system, the method including receiving, via a physical downlink control channel (PDCCH), downlink control information (DCI) for downlink scheduling. The DCI includes an SRS request for triggering transmission of the aperiodic SRS. The method further includes detecting the SRS request; and transmitting the aperiodic SRS on an uplink (UL) component carrier (CC), which is linked to a downlink (DL) CC in which a physical downlink shared channel (PDSCH) is scheduled by the DCI, among a plurality of UL CCs. If a carrier indicator field (CIF) is configured, the UL CC is indicated by the CIF. |

1. A method for transmitting, by a user equipment (UE), an aperiodic sounding reference signal (SRS) in a wireless communication system, the method comprising:
receiving, via a physical downlink control channel (PDCCH), downlink control information (DCI) for downlink scheduling, wherein the DCI includes an SRS request for triggering transmission of the aperiodic SRS; detecting the SRS request; and transmitting the aperiodic SRS on an uplink (UL) component carrier (CC), which is linked to a downlink (DL) CC in which a physical downlink shared channel (PDSCH) is scheduled by the DCI, among a plurality of UL CCs, wherein if a carrier indicator field (CIF) is configured, the UL CC is indicated by the CIF. |
