The circuitry, in operation, obtains, from the DCI signalling, a scheduling indication. The scheduling indication indicates a number, N, of transport blocks (TBs), N being greater than 1, and a scheduling gap, K. The scheduling gap indicates an offset in time-domain between the reception of the DCI signalling and the N TBs. The circuitry determines, if K is smaller than a minimum scheduling gap, Kmin, based on the DCI signalling and Kmin, that zero or more resources are scheduled by the DCI signalling. Each of the zero or more scheduled resources is i) at least Kmin slots after a slot carrying the DCI signalling, and ii) to be used for a transmission of a TB of the N TBs.
