A method in a wireless device comprising: receiving a downlink signal, wherein the downlink signal comprises a Physical Downlink Control Channel, PDCCH, and a Physical Downlink Shared Channel, PDSCH, the PDCCH having first Downlink Control Information, DCI, indicating at least second Downlink Control information, DCI, in the PDSCH; characterized by : performing one of encoding and decoding user data in the PDSCH based on the first DCI and second DCI wherein the first DCI comprises a Modulation and Coding Scheme, MCS, field which has 5 bits, and wherein 3 bits of the MCS field are used to indicate a ratio of resource elements, RE, used for the second DCI over an effective RE number in allocated Physical Resource blocks, PRBs; and determining a number of REs occupied by the second DCI based on the 3 bits of the MCS field of the first DCI by calculating the following: N RE exDCI = ⌈ N PRB DL × R exDCIrate RE ⌉ × N symbol RE where N RE exDCI refers to the number of REs of the second DCI, N PRB DL refers to an allocated Physical Resource Block, PRB, number indicated by the first DCI, N symbol RE refers to an effective RE number per Orthogonal Frequency Division Multiplexing, OFDM, symbol within the allocated PRBs and R exDCIrate RE refers to the 3-bit of the MCS field of the first DCI, and ┌ ┐ refers to a ceiling function. receiving a downlink signal, wherein the downlink signal comprises a Physical Downlink Control Channel, PDCCH, and a Physical Downlink Shared Channel, PDSCH, the PDCCH having first Downlink Control Information, DCI, indicating at least second Downlink Control information, DCI, in the PDSCH; characterized by : performing one of encoding and decoding user data in the PDSCH based on the first DCI and second DCI wherein the first DCI comprises a Modulation and Coding Scheme, MCS, field which has 5 bits, and wherein 3 bits of the MCS field are used to indicate a ratio of resource elements, RE, used for the second DCI over an effective RE number in allocated Physical Resource blocks, PRBs; and determining a number of REs occupied by the second DCI based on the 3 bits of the MCS field of the first DCI by calculating the following: N RE exDCI = ⌈ N PRB DL × R exDCIrate RE ⌉ × N symbol RE where N RE exDCI refers to the number of REs of the second DCI, N PRB DL refers to an allocated Physical Resource Block, PRB, number indicated by the first DCI, N symbol RE refers to an effective RE number per Orthogonal Frequency Division Multiplexing, OFDM, symbol within the allocated PRBs and R exDCIrate RE refers to the 3-bit of the MCS field of the first DCI, and ┌ ┐ refers to a ceiling function. performing one of encoding and decoding user data in the PDSCH based on the first DCI and second DCI wherein the first DCI comprises a Modulation and Coding Scheme, MCS, field which has 5 bits, and wherein 3 bits of the MCS field are used to indicate a ratio of resource elements, RE, used for the second DCI over an effective RE number in allocated Physical Resource blocks, PRBs; and determining a number of REs occupied by the second DCI based on the 3 bits of the MCS field of the first DCI by calculating the following: N RE exDCI = ⌈ N PRB DL × R exDCIrate RE ⌉ × N symbol RE where N RE exDCI refers to the number of REs of the second DCI, N PRB DL refers to an allocated Physical Resource Block, PRB, number indicated by the first DCI, N symbol RE refers to an effective RE number per Orthogonal Frequency Division Multiplexing, OFDM, symbol within the allocated PRBs and R exDCIrate RE refers to the 3-bit of the MCS field of the first DCI, and ┌ ┐ refers to a ceiling function. <EOS>
