Abstract: Disclosed herein are a method and a device for transmitting a message in an initial access procedure by a user equipment (UE) in a wireless communication system. According to the present disclosure, a UE may transmit to a base station capability information associated with transmission power of the UE and the information may include a subset including at least one transmit precoding matrix indicator (TPMI) supported by the UE. The UE may receive first control information for transmitting a message associated with an initial access and the control information may include a TPMI used for the UE to transmit the message. Thereafter, the UE may transmit to the base station the message by using transmission power determined based on the TPMI and the transmission power may be determined according to whether the TPMI is included in the at least one TPMI.

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.
