In some embodiments, a method performed by a wireless device comprises receiving a resource allocation for an uplink transmission that allocates resources in one or more partially allocated interlaces and performing an uplink transmission on the allocated resources in the one or more partially allocated interlaces in accordance with the resource allocation. In this manner, a low-complexity approach to support flexible frequency domain resource allocation is provided. In addition, using this approach, an interlace may be shared by two or more wireless devices, which may increase spectral efficiency and reduce latency. ## Claims ### Claim 1 A method performed by a wireless device, the method comprising: receiving a resource allocation for an uplink transmission that allocates resources in one or more partially allocated interlaces; and performing an uplink transmission on allocated resources in the one or more partially allocated interlaces in accordance with the resource allocation; wherein the resource allocation comprises: information that indicates the one or more partially allocated interlaces; and one of the group consisting of: information that indicates one or more physical resource blocks within the one or more partially allocated interlaces that are allocated for the uplink transmission from the wireless device; and for each partially allocated interlace of the one or more partially allocated interlaces, information that indicates one or more physical resource blocks within the partially allocated interlace that are allocated for the uplink transmission from the wireless device; wherein the information that indicates the one or more physical resource blocks is defined using a modified New Radio, NR, Resource Allocation, RA, type 1 resource allocation scheme. ### Claim 2 (depends on 1) The method of claim 1 wherein the resource allocation comprises: information that indicates one or more physical resource blocks within the one or more partially allocated interlaces that are allocated for the uplink transmission from the wireless device. ### Claim 3 (depends on 2) The method of claim 2 wherein the information that indicates the one or more partially allocated interlaces comprises a bitmap of length equal to a number of interlaces that can be allocated where bits in the bitmap indicate which interlaces are partially allocated. ### Claim 4 (depends on 2) The method of claim 2 wherein the information that indicates the one or more partially allocated interlaces comprises a bit sequence that maps to a predefined combination of interlaces that are partially allocated. ### Claim 5 (depends on 1) The method of claim 1 wherein the resource allocation comprises: for each partially allocated interlace of the one or more partially allocated interlaces, information that indicates one or more physical resource blocks within the partially allocated interlace that are allocated for the uplink transmission from the wireless device. ### Claim 6 (depends on 5) The method of claim 5 wherein the information that indicates the one or more physical resource blocks for each partially allocated interlace is common information that indicates the one or more physical resource blocks for each partially allocated interlace. ### Claim 7 (depends on 1) The method of claim 1 wherein the uplink transmission is in a wireless communication network with wideband operations consisting of a number of sub-bands, and the wireless device excludes some physical resource block(s) in a guard band between sub-bands or channels. ### Claim 8 (depends on 1) The method of claim 1 wherein the uplink transmission is in a wireless communication network with wideband operations consisting of a number of sub-bands, and the start and length of the one or more sub-bands are indicated by the modified NR RA type 1 resource allocation scheme. ### Claim 9 A wireless device for a cellular communications system, the wireless device adapted to: receive a resource allocation for an uplink transmission that allocates resources in one or more partially allocated interlaces;

and one of the group consisting of: information that indicates one or more physical resource blocks within the one or more partially allocated interlaces that are allocated for the uplink transmission from the wireless device; and for each partially allocated interlace of the one or more partially allocated interlaces, information that indicates one or more physical resource blocks within the partially allocated interlace that are allocated for the uplink transmission from the wireless device; wherein the information that indicates the one or more physical resource blocks is defined using a modified New Radio, NR, Resource Allocation, RA, type 1 resource allocation scheme. ### Claim 10 A method performed by a base station comprising: transmitting, to a wireless device, a resource allocation for an uplink transmission that allocates resources in one or more partially allocated interlaces; wherein the resource allocation comprises: information that indicates the one or more partially allocated interlaces; and one of the group consisting of: information that indicates one or more physical resource blocks within the one or more partially allocated interlaces that are allocated for the uplink transmission from the wireless device; and for each partially allocated interlace of the one or more partially allocated interlaces, information that indicates one or more physical resource blocks within the partially allocated interlace that are allocated for the uplink transmission from the wireless device; wherein the information that indicates the one or more physical resource blocks is defined using a modified New Radio, NR, Resource Allocation, RA, type 1 resource allocation scheme. ### Claim 11 (depends on 10) The method of claim 10 wherein the resource allocation comprises: information that indicates one or more physical resource blocks within the one or more partially allocated interlaces that are allocated for the uplink transmission from the wireless device. ### Claim 12 (depends on 11) The method of claim 11 wherein the information that indicates the one or more partially allocated interlaces comprises a bitmap of length equal to a number of interlaces that can be allocated where bits in the bitmap indicate which interlaces are partially allocated. ### Claim 13 (depends on 11) The method of claim 11 wherein the information that indicates the one or more partially allocated interlaces comprises a bit sequence that maps to a predefined combination of interlaces that are partially allocated. ### Claim 14 (depends on 11) The method of claim 11 wherein the uplink transmission is in a wireless communication network with wideband operations consisting of a number of sub-bands, and the wireless device excludes some physical resource block(s) in a guard band between sub-bands or channels. ### Claim 15 (depends on 11) The method of claim 11 wherein the uplink transmission is in a wireless communication network with wideband operations consisting of a number of sub-bands, and the start and length of the one or more sub-bands are indicated by the modified NR RA type 1 resource allocation scheme. ### Claim 16 (depends on 10) The method of claim 10 wherein the resource allocation comprises: for each partially allocated interlace of the one or more partially allocated interlaces, information that indicates one or more physical resource blocks within the partially allocated interlace that are allocated for the uplink transmission from the wireless device. ### Claim 17 (depends on 16) The method of claim 16 wherein the information that indicates the one or more physical resource blocks for each partially allocated interlace is common information that indicates the one or more physical resource blocks for each partially allocated interlace. ### Claim 18 A base station for a cellular communications system, the base station adapted to: transmit, to a wireless device, a resource allocation for an uplink transmission that allocates resources in one or more partially allocated interlaces; wherein the resource allocation comprises: information that indicates the one or more partially allocated interlaces; and one of the group consisting of: information that indicates one or more physical resource blocks within the one or more partially allocated interlaces that are allocated for the uplink transmission from the wireless device;
