Abstract: A method for transmitting a sounding reference signal (SRS) by a by a user equipment (UE) includes: receiving, from a base station, first information on a number of SRS symbols configured for one slot and second information on a number of repetitions of symbols configured for transmission of an SRS; determining whether the number of repetitions is greater than the number of the SRS symbols; when the number of repetitions is greater than the number of the SRS symbols, determining the number of repetitions of the symbols by a value identical to the number of the SRS symbols; and transmitting the SRS based on the determined number of repetitions. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station, or a network.

Abstract: According to the present invention, a method of transmitting and receiving an uplink phase tracking reference signal between a user equipment and a base station in a wireless communication and an apparatus supporting the same are disclosed.
According to an example applicable to the present invention, a user equipment can transmit an uplink PT-RS to a base station using the actual number of PT-RS ports which is determined based on the maximum uplink phase tracking reference signal (PT-RS) ports received from the base station and a precoding matrix set to the UE.
