Disclosed are a method for transmitting a PUSCH and a device therefor, the method comprising the steps of: receiving an uplink (UL) grant from a base station; selecting at least one radio resource among a first radio resource which is a radio resource allocated by the UL grant, and a predetermined second radio resource; and transmitting a PUSCH using the selected at least one radio resource, wherein the second radio resource is a radio resource enabling PUSCH transmission without receiving the UL grant. ## Claims ### Claim 1 A method for transmitting a physical uplink shared channel (PUSCH) by a User Equipment (UE) in a wireless communication system, the method comprising: receiving an uplink (UL) grant from a base station; selecting at least one radio resource of a first radio resource and a second radio resource, the first radio resource being a radio resource allocated by the UL grant and the second radio resource being preconfigured; and performing PUSCH transmission using the at least one selected radio resource, wherein the second radio resource is a radio resource available for the PUSCH transmission without receiving the UL grant. ### Claim 2 (depends on 1) The method of claim 1, wherein, when the first radio resource and the second radio resource are radio resources for different frequency regions in the same slot, the at least one radio resource is selected as only one of the first radio resource and the second radio resource based on a preconfigured priority. ### Claim 3 (depends on 2) The method of claim 2, wherein the preconfigured priority is at least one priority selected from among a priority according to sizes of the radio resources, a priority according to reliability of the radio resources, and a priority according to HARQ feedback timing corresponding to transmission of the radio resources. ### Claim 4 (depends on 2) The method of claim 2, wherein the preconfigured priority is a priority according to a characteristic of a payload transmitted from a higher layer of the UE to a physical layer. ### Claim 5 (depends on 2) The method of claim 2, wherein the preconfigured priority is a priority according to reliability or a latency requirement for uplink control information (UCI). ### Claim 6 (depends on 1) The method of claim 1, wherein the at least one radio resource is selected from the first radio resource and the second radio resource based on a preconfigured priority, wherein the preconfigured priority is a priority according to whether piggyback of uplink control information (UCI) is allowed on the first radio resource and the second radio resource. ### Claim 7 (depends on 6) The method of claim 6, wherein the preconfigured priority further comprises a priority according to a type of the received UL grant. ### Claim 8 (depends on 1) The method of claim 1, wherein, when the first radio resource and the second radio resource are radio resources for different slots and an interval between the slots is within a preconfigured interval, wherein the at least one radio resource is selected as the first radio resource. ### Claim 9 (depends on 8) The method of claim 8, wherein the preconfigured interval is configured based on HARQ timing for the second radio resource. ### Claim 10 (depends on 8) The method of claim 8, wherein, when the first radio resource by the UL grant is acquired during repetition using the second radio resource, wherein the at least one radio resource is selected as the first radio resource, and wherein the repetition using the second radio resource is halted. ### Claim 11 (depends on 8) The method of claim 8, wherein, when the first radio resource by the UL grant is acquired after completion of repetition using the second radio resource, wherein the at least one radio resource is selected as the first radio resource, and wherein the UE performs the repetition again using the first radio resource. ### Claim 12 (depends on 1) The method of claim 1, further comprising: receiving, from the base station, a halting signal for halting transmission of the PUSCH using the second radio resource, wherein, when the halting signal is received, the at least one radio resource is determined only as the first radio resource. ### Claim 13 (depends on 1) The method of claim 1, further comprising: receiving, from the base station, a permission signal for permitting simultaneous transmission of the PUSCH using the first radio resource and the second radio resource at the same time. ### Claim 14 (depends on 13) The method of claim 13, wherein, when the permission signal is received and the first radio resource and the second radio resource are radio resources for different frequency regions in the same slot, the first radio resource and the second radio resource are used for different transport blocks. ### Claim 15 (depends on 13) The method of claim 13, wherein, when the permission signal is received, and the first radio resource and the second radio resource are radio resources for different frequency regions in the same slot, wherein a transmission power for the second radio resource is allocated prior to a transmission power for the first radio resource in consideration of a path loss. ### Claim 16 (depends on 13) The method of claim 13, wherein, when the permission signal is received, and the first radio resource and the second radio resource include a third radio resource overlapped in a slot and frequency domain, wherein the at least one radio resource is selected as the first radio resource with a portion corresponding to the third radio resource punctured or rate-matched in the first radio resource. ### Claim 17 (depends on 1) The method of claim 1, wherein the first radio resource and the second radio resource are distinguished by at least one of a demodulation reference signal (DMRS) sequence, a DMRS mapping pattern, and a cyclic redundancy check (CRC) mask. ### Claim 18 A User Equipment (UE) for transmitting a physical uplink shared channel (PUSCH) in a wireless communication system, comprising: a radio frequency (RF) module configured to transmit and receive signals to and from a base station; and a processor configured to: control the RF module to receive an uplink (UL) grant from a base station; select at least one radio resource of a first radio resource and a second radio resource, the first radio resource being a radio resource allocated by the UL grant and the second radio resource being preconfigured; and control the RF module to perform PUSCH transmission using the at least one selected radio resource, wherein the second radio resource is a radio resource available for the PUSCH transmission without receiving the UL grant.
