The control information may include a bitmap that indicates at one or more groups of time and frequency resources excluded/included for the data transmission region. ## Claims ### Claim 1 A method in a wireless device, the method comprising: receiving a signal from a network node indicating a set of time and frequency resources allocated for a data transmission, wherein a first subset of the indicated set of time and frequency resources allocated for the data transmission overlap with time and frequency resources in one or more control regions, the signal further indicating a second subset of time and frequency resources from the one or more control resource regions excluded for the data transmission; and receiving data based on the received signal. ### Claim 2 (depends on 1) The method of claim 1, wherein the signal is a physical downlink control channel (PDCCH). ### Claim 3 (depends on 1) The method of claim 1, wherein the signal comprises a bitmap for indicating the second subset of time and frequency resources from the one or more control resource regions excluded from the data transmission. ### Claim 4 (depends on 1) The method of claim 1, wherein the signal comprises an identifier of at least one control resource region excluded from the data transmission. ### Claim 5 (depends on 1) The method of claim 1, wherein the one or more control resource regions correspond to one or more Control Resource Sets (CORESETs). ### Claim 6 (depends on 1) The method of claim 1, wherein the second subset of time and frequency resources are allocated for a physical downlink control channel (PDCCH). ### Claim 7 (depends on 1) The method of claim 1, wherein the set of time and frequency resources allocated for a data transmission excludes resources outside of the one or more control resource regions. ### Claim 8 (depends on 1) The method of claim 1, wherein the set of time and frequency resources allocated for a data transmission comprises resources within the one or more control resource regions and resources outside of any control resource regions. ### Claim 9 (depends on 1) The method of claim 1, wherein a frequency range of the resources within the one or more control resource regions is one of the same as a frequency range of the resources outside of the one or more control resource regions and different than a frequency range of the resources outside of the one or more control resource regions. ### Claim 10 A wireless device comprising processing circuitry, the processing circuitry operable to: receiving a signal from a network node indicating a set of time and frequency resources allocated for a data transmission, wherein a first subset of the indicated set of time and frequency resources allocated for the data transmission overlap with time and frequency resources in one or more control regions, the signal further indicating a second subset of time and frequency resources from the one or more control resource regions excluded for the data transmission; and transmitting data based on the received signal. ### Claim 11 A method in a network node, the method comprising: determining a set of time and frequency resources allocated for a data transmission, wherein a first subset of the set of time and frequency resources allocated for the data transmission overlap with time and frequency resources in one or more control regions; and transmitting a signal indicating the set of time and frequency resources allocated for a data transmission to a wireless device, the signal further indicating a second subset of time and frequency resources from the one or more control resource regions excluded for the data transmission. ### Claim 12 (depends on 11) The method of claim 11, wherein the signal is a physical downlink control channel (PDCCH). ### Claim 13 (depends on 11) The method of claim 11, wherein the signal comprises a bitmap for indicating the second subset of time and frequency resources from the one or more control resource regions excluded from the data transmission. ### Claim 14 (depends on 11) The method of claim 11, wherein the signal comprises an identifier of at least one control resource region excluded from the data transmission. ### Claim 15 (depends on 11) The method of claim 11, wherein the one or more control resource regions correspond to one or more Control Resource Sets (CORESETs). ### Claim 16 (depends on 11) The method of claim 11, wherein the second subset of time and frequency resources are allocated for a physical downlink control channel (PDCCH). ### Claim 17 (depends on 11) The method of claim 11, wherein the set of time and frequency resources allocated for a data transmission excludes resources outside of the one or more control resource regions. ### Claim 18 (depends on 11) The method of claim 11, wherein the set of time and frequency resources allocated for a data transmission comprises resources within the one or more control resource regions and resources outside of any control resource regions. ### Claim 19 (depends on 11) The method of claim 11, wherein a frequency range of the resources within the one or more control resource regions is one of the same as a frequency range of the resources outside of the one or more control resource regions and different than a frequency range of the resources outside of the one or more control resource regions.
