Method and apparatus for transmitting srs in wireless celluar mobile communication system

A method by a terminal connected to a first cell operating by a frequency division duplex (FDD) mode for transmitting a signal, the method comprising:

• receiving a message configuring a second cell operating by a time division duplex (TDD) mode, wherein a sounding reference signal (SRS) transmission in an uplink pilot time slot (UpPTS) is configured to the second cell;
• identifying a position of a symbol for transmitting the SRS in the UpPTS of the second cell;
• and
• determining whether to transmit the SRS in the position of the symbol based on a result of the identification.

A method by a base station for receiving a signal, the method comprising:

• transmitting, to the terminal, a message configuring a second cell operating by a time division duplex (TDD) mode on a first cell operating by a frequency division duplex (FDD) mode, wherein a sounding reference signal (SRS) reception in an uplink pilot time slot (UpPTS) is configured to the second cell;
• identifying a position of a symbol for receiving the SRS in the UpPTS of the second cell;
• and
• determining whether to receive the SRS in the position of the symbol based on a result of the identification.

A terminal connected to a first cell operating by a frequency division duplex (FDD) mode for transmitting a signal, the terminal comprising:

• a transceiver configured to transmit and receive a signal;
• and
• a controller configured to:
• control the transceiver to receive a message configuring a second cell operating by a time division duplex (TDD) mode, wherein a sounding reference signal (SRS) transmission in an uplink pilot time slot (UpPTS) is configured to the second cell,
• identify a position of a symbol for transmitting the SRS in the UpPTS of the second cell, and
• determine whether to transmit the SRS in the position of the symbol based on a result of the identification.
