Abstract: A method for a terminal transmitting a signal according to a resource allocation priority may comprise the steps of: when a sounding reference signal (SRS) symbol and a physical uplink control channel (PUCCH) symbol are configured so as to overlap, transmitting an SRS in a non-overlapping symbol; and dropping the transmission of the SRS in the overlapping symbol. The present invention can improve communication performance by being able to carry out transmission according to a resource allocation priority rule, when the SRS and PUCCH resource areas overlap.

Abstract: The present specification provides a method for transmitting and receiving a signal by means of a beam in a wireless communication system. The method for a terminal for transmitting and receiving a signal by means of one or more beams according to the present specification may comprise the steps of: receiving sounding reference signal (SRS) resource configuration information for an SRS transmission from a base station, the SRS resource configuration information comprising configuration information indicating one or more previously configured timing advance values for one or more SRS resources; receiving, from the base station, control information indicating a particular SRS resource from among the one or more SRS resources; and transmitting an uplink signal at the configured temporal uplink transmission point using the timing advance value corresponding to the particular SRS resource.

Abstract: A method for transmitting and receiving, by a user equipment (UE), a phase noise compensation reference signal (PCRS) in a wireless communication system is disclosed. The method includes receiving, from a base station, control information related to a transmission of a downlink data, the control information including at least one of a precoding scheme related to the downlink data, a number of transmission ranks, or a modulation and coding scheme (MCS) level; checking a transmission location of a demodulation reference signal (DM-RS) for demodulating the downlink data based on the received control information; and receiving, from the base station, the PCRS on at least one symbol after a transmission symbol of the DM-RS considering the checked transmission location of the DM-RS.
