Conflict handling of multiple DCI

An integrated circuit for a data transmitting device for transmitting data to a data receiving node over a wireless channel in a communication system, the integrated circuit comprising:

• grant receiving circuitry, which, in operation, receives a first resource grant and a second resource grant, wherein the first resource grant is a multiple subframe grant indicating allocation of resources for a plurality of subframes, and the second resource grant is a single subframe grant indicating allocation of resources for a single subframe;
• transmission control circuitry, which, in operation, selects the first resource grant or the second resource grant for data to be transmitted in a first subframe, and selects the first resource grant or the second resource grant for data to be transmitted in a second subframe, wherein,
• in a case where (1) the first subframe is one of the plurality of subframes and the single subframe and (2) the second subframe is another one of the plurality of subframes and is prior to the first subframe, the transmission control circuitry selects the second resource grant for the data to be transmitted in the first subframe, selects the first resource grant for the data to be transmitted in the second subframe, and selects neither the first resource grant nor the second resource grant for data to be transmitted in subframes of the plurality of subframes that are subsequent to the first subframe;
• and
• transmitting circuitry, which, in operation, transmits the data in the first subframe according to the selected first resource grant or second resource grant for the data to be transmitted in the first subframe, and transmits the data in the second subframe according to the selected first resource grant or second resource grant for the data to be transmitted in the second subframe.
