    Abstract: Systems and techniques or transmitting and receiving a sounding reference signal (SRS) in a wireless communication system. In some implementations, a method for transmitting, by a terminal, an SRS in a wireless communication system includes: receiving configuration information for transmission of the SRS from a base station; and transmitting the SRS to the base station by using one or more SRS resources for transmission of the SRS, the configuration information including the one or more SRS resources and information relating to usage of the one or more SRS resources, wherein a guard period relating to the one or more SRS resources is configured, and when the transmissions of the guard period and a particular uplink channel configured for the terminal overlap each other, the priority between the guard period and the particular uplink channel is configured to be the same as that between the SRS and the particular uplink channel.

    Abstract: A method for a base station to transmit a signal allowing a terminal to remove phase noise in an mmWave communication system, according to an embodiment of the present specification, may be provided. Here, the method for transmitting a signal for removing phase noise comprises: a step of generating a phase tracking reference signal (PTRS) and a first RS; a step of assigning the PTRS and the first RS to a resource block; and a step of transmitting the assigned PTRS and first RS, wherein the step of assigning the PTRS and the first RS includes a step of changing a frequency location of the PTRS if the PTRS and the first RS collide in the resource block, wherein the changed PTRS frequency location may be changed to a frequency location, across frequencies on which a predetermined demodulation reference signal (DMRS) port, associated with the PTRS, in a DMRS port group is located, which is closest to the existing PTRS frequency location and avoids collision with the first RS.

    Abstract: This specification provides a method for transmitting, by a user equipment (UE), a CSI (Channel State Information) report in a wireless communication system. More specifically, the method includes: receiving, from a base station, downlink control information (DCI) including information for triggering the CSI report; computing CSI based on the number of symbols related to a time for computing the CSI; and transmitting the CSI report to the base station, in which the number of symbols related to the time for computing the CSI is defined based on information for the number of antenna ports, information for a CSI-RS resource, information for a bandwidth granularity, and information for a CSI codebook type.

    Abstract: A method of receiving phase tracking reference signal (PT-RS) by a user equipment (UE) in a wireless communication system, the method includes determining one or more resource blocks to which the PT-RS is mapped among N resource blocks allocated to the UE; and receiving the PT-RS via the one or more second resource blocks, wherein the N resource blocks are indexed as second resource block indices 0 to N−1 from a resource block having a lowest index of first resource block indices to a resource block having a highest index of the first resource block indices, wherein the PT-RS is mapped to the one or more resource blocks having indices of the second resource block indices and the indices are determined based on a first value related to a frequency density of the PT-RS and a second value related to a resource block offset, wherein the first value is determined based on a scheduled bandwidth related with the N resource blocks allocated to the UE, and wherein N is a natural number.
