More particularly, a method for transmitting a PUSCH based on combination of the information about the interlaces and the one or more RB sets included in the DCI. and devices supporting same. ## Claims ### Claim 1 A method of transmitting a uplink signal by a user equipment (UE) in a wireless communication system supporting an unlicensed band, the method comprising: receiving, from a base station (BS), a downlink control information (DCI) including resource allocation information for an interlaced resource block (RB) based Physical Uplink Shared Channel (PUSCH) transmission, wherein the resource allocation information includes information about interlaces and one or more RB sets, which are configured within a bandwidth for a carrier, used for the PUSCH transmission; and transmitting, to the BS, a PUSCH based on a combination of the information about the interlaces and the one or more RB sets included in the DCI, wherein resources for the PUSCH transmission on frequency domain are determined based on an intersection of the interlaces and the one or more RB sets indicated by the resource allocation information. ### Claim 2 (depends on 1) The method of claim 1, wherein each of the interlaces includes 10 RBs equally distributed at intervals of 10 RBs within the bandwidth. ### Claim 3 (depends on 1) The method of claim 1, wherein resources for the PUSCH transmission on frequency domain are allocated in units of interlaces. ### Claim 4 (depends on 1) The method of claim 1, wherein the bandwidth is divided into a plurality of bands and a channel access procedure is performed for each of the one or more RB sets independently, and wherein each of the one or more RB sets used for the PUSCH transmission is a band that the channel access procedure performed by the BS is successful. ### Claim 5 (depends on 1) The method of claim 1, further comprising: receiving, from the BS, information for configuring the interlaced RBs based PUSCH transmission. ### Claim 6 A user equipment (UE) for transmitting an uplink signal in a wireless communication system supporting an unlicensed band, the UE comprising: at least one processor; and at least one computer memory operatively coupled to the at least one processor and configured to cause, when executed, the at least one processor to perform an operation, the operation comprising: receiving, from a base station (BS), a downlink control information (DCI) including resource allocation information for an interlaced resource block (RB) based Physical Uplink Shared Channel (PUSCH) transmission, wherein the resource allocation information includes information about interlaces and one or more RB sets, which are configured within a bandwidth for a carrier, used for the PUSCH transmission; and transmitting, to the BS, a PUSCH based on a combination of the information about the interlaces and the one or more RB sets included in the DCI, wherein resources for the PUSCH transmission on frequency domain are determined based on an intersection of the interlaces and the one or more RB sets indicated by the resource allocation information. ### Claim 7 (depends on 6) The UE of claim 6, wherein each of the interlaces includes 10 RBs equally distributed at intervals of 10 RBs within the bandwidth. ### Claim 8 (depends on 6) The UE of claim 6, wherein resources for the PUSCH transmission in frequency domain are allocated in units of interlaces. ### Claim 9 (depends on 6) The UE of claim 6, wherein the bandwidth is divided into a plurality of bands and a channel access procedure is performed for each of the one or more RB sets independently, and wherein each of the one or more RB sets used for the PUSCH transmission is a band that the channel access procedure performed by the BS is successful. ### Claim 10 (depends on 6) The UE of claim 6, wherein the operation further comprises receiving, from the BS, information for configuring the interlaced RB based PUSCH transmission. ### Claim 11 A method of receiving an uplink signal by a base station (BS) in a wireless communication system supporting an unlicensed band, the method comprising: transmitting, to a user equipment (UE), a downlink control information (DCI) including resource allocation information for an interlaced resource block (RB) based Physical Uplink Shared Channel (PUSCH) transmission of the UE, wherein the resource allocation information includes information about interlaces and one or more RB sets which are configured within a bandwidth for a carrier, used for the PUSCH transmission of the UE, and receiving, from the UE, the PUSCH based on a combination of the information about the interlaces and the one or more RB sets included in the DCI, wherein resources for the PUSCH transmission on frequency domain are determined based on an intersection of the interlaces and the one or more RB sets indicated by the resource allocation information. ### Claim 12 A base station (BS) for receiving an uplink signal in a wireless communication system supporting an unlicensed band, the BS comprising: at least one processor; and at least one computer memory operatively coupled to the at least one processor and configured to cause, when executed, the at least one processor to perform an operation, the operation comprising: transmitting, to a user equipment (UE), a downlink control information (DCI) including resource allocation information for an interlaced resource block (RB) based Physical Uplink Shared Channel (PUSCH) transmission of the UE, wherein the resource allocation information includes information about interlaces and one or more RB sets which are configured within a bandwidth for a carrier, used for the PUSCH transmission of the UE, and receiving, from the UE, the PUSCH based on a combination of the information about the interlaces and the one or more RB sets included in the DCI, wherein resources for the PUSCH transmission on frequency domain are determined based on an intersection of the interlaces and the one or more RB sets indicated by the resource allocation information.
