Abstract
The present invention relates to a method and apparatus in which a terminal transmits aperiodic sounding reference signals (SRSs) in a wireless communication system. The terminal receives a triggering bit for triggering the transmission of the aperiodic SRSs from a base station, and transmits the aperiodic SRSs through at least one uplink (UL) component carrier (CC) from among a plurality of uplink component carriers.
Claims14
A method of transmitting, by a terminal, an aperiodic sounding reference signal (SRS) in a wireless communication system, the method comprising:
- receiving a triggering bit for triggering transmission of the aperiodic SRS from a base station;
- and
- transmitting the aperiodic SRS through at least one uplink (UL) component carrier (CC) among a plurality of UL CCs.
- wherein the at least one UL CC for transmitting the aperiodic SRS is a UL CC having a system information block (SIB)-2 linkage relation with a downlink (DL) CC for transmitting a UL grant including the triggering bit.
A terminal in a wireless communication system, the terminal comprising:
- a radio frequency (RF) unit for transmitting or receiving a radio signal;
- and
- a processor coupled to the RF unit,
- wherein the processor is configured for:
- receiving a triggering bit for triggering transmission of an aperiodic sounding reference signal (SRS) from a base station;
- and
- transmitting the aperiodic SRS through at least one uplink (UL) component carrier (CC) among a plurality of UL CCs,
- wherein the at least one UL CC for transmitting the aperiodic SRS is a UL CC having a system information block (SIB)-2 linkage relation with a downlink (DL) CC for transmitting a UL grant including the triggering bit.
A method of transmitting, by a terminal, an aperiodic sounding reference signal (SRS) in a wireless communication system, the method comprising:
- receiving a triggering bit for triggering transmission of the aperiodic SRS from a base station, and
- transmitting the aperiodic SRS through at least one uplink (UL) component carrier (CC) among a plurality of UL CCs,
- wherein the at least one UL CC for transmitting the aperiodic SRS is a UL CC indicated by a UL grant including the triggering bit or a UL CC having an index adjacent to the of a UL CC having system information block (SIB)-2 linkage relation with a downlink (DL) CC for transmitting the UL grant including the triggering bit.
