METHOD AND APPARATUS FOR TRANSMITTING AND RECEIVING SOUNDING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM

WIPO Patent Application WO/2021/066634

A1

A method of transmitting a sounding reference signal (SRS) by a terminal in a wireless communication system, according to an embodiment of the present specification, comprises: receiving configuration information related to transmission of a sounding reference signal (SRS); transmitting a message including information on power headroom (PH) related to the transmission power of the SRS; and receiving DCI triggering the transmission of the SRS; and transmitting the SRS with transmission power on the basis of a transmission power control command (TPC command) related to control of the transmission power. The SRS is set in a region consisting of at least one symbol excluding the last symbol of a subframe; the message comprises at least one specific field; and the specific field is associated with a specific type of power headroom report.
