Abstract
Provided is a method for transmitting a sounding reference signal (SRS) in a wireless communication system. Specifically, a method performed by a user equipment includes: receiving from a base station resource configuration information for transmitting the SRS on a specific component carrier (CC); performing carrier switching from a first component carrier to a second component carrier; and transmitting the SRS to the base station on the switched component carrier based on the received resource configuration information.
Claims20
A method for transmitting a sounding reference signal (SRS) in a wireless communication system, the method performed by a user equipment, the method comprising:
- receiving, from a base station (BS), resource configuration information for transmitting the SRS;
- performing carrier switching from a first component carrier (CC) to a second component carrier,
- wherein a subcarrier spacing of the first component carrier is different from a subcarrier spacing of the second component carrier, and
- wherein a carrier switching start position in the first component carrier is determined based on (i) a start position of a transmission symbol interval of the SRS and (ii) a carrier switching time;
- and
- transmitting, to the BS, the SRS on the second component carrier based on the resource configuration information.
A user equipment configured to transmit a sounding reference signal (SRS) in a wireless communication system, the user equipment comprising:
- a receiver and a transmitter;
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
- receiving, from a base station (BS) through the receiver, resource configuration information for transmitting the SRS;
- performing carrier switching from a first component carrier (CC) to a second component carrier,
- wherein a subcarrier spacing of the first component carrier is different from a subcarrier spacing of the second component carrier, and
- wherein a carrier switching start position in the first component carrier is determined based on (i) a start position of a transmission symbol interval of the SRS and (ii) a carrier switching time;
- and
- transmitting, through the transmitter, the SRS to the BS on the second component carrier based on the resource configuration information.
An apparatus configured to control a user equipment to transmit a sounding reference signal (SRS) in a wireless communication system, the apparatus comprising:
- at least one processor;
- and
- at least one computer memory operably connectable to the at least one processor and storing instructions that, when executed by the at least one processor, perform operations comprising:
- receiving, from a base station (BS), resource configuration information for transmitting the SRS;
- performing carrier switching from a first component carrier (CC) to a second component carrier,
- wherein a subcarrier spacing of the first component carrier is different from a subcarrier spacing of the second component carrier, and
- wherein a carrier switching start position in the first component carrier is determined based on (i) a start position of a transmission symbol interval of the SRS and (ii) a carrier switching time;
- and
- transmitting the SRS to the BS on the second component carrier based on the resource configuration information.
