1. A user equipment (UE) comprising:

  • a receiver configured to receive a downlink control information (DCI) format that configures transmissions of a number of physical uplink data channels (PUSCHs) over a number of subframes up to a predetermined maximum number of NSF subframes, wherein the DCI format includes;

    a number of subframes field that is represented by ┌

    log2 (NSF)┐

    bits and indicates a number nSF

    NSF of subframes for nSF PUSCH transmissions,a timing offset field that includes a timing offset ot for a subframe of a first of the PUSCH transmissions that is determined as n+k+ot, wherein n is a subframe of the DCI format reception and k is a minimum number of subframes for a PUSCH transmission after the DCI format reception,a hybrid automatic repeat request (HARQ) process number field that is represented by ┌

    log2(NHARQ)┐

    bits and indicates a HARQ process number nHARQ from a total of NHARQ HARQ processes, wherein HARQ process number nHARQ applies for the first PUSCH transmission, HARQ process number (nHARQ j−

    1)modNHARQ applies for a j-th of the PUSCH transmissions, and 1≦

    j≦

    nSF,a new data indicator (NDI) field that is represented by NSF bits and indicates whether a PUSCH transmission, from the nSF PUSCH transmissions, conveys a new data transport block (TB) or a retransmission of a data TB; and

    a transmitter configured to transmit the nSF PUSCH transmissions over the nSF subframes,wherein ┌



    is a ceiling function that rounds a number to its immediately next larger integer and log2(x) is a logarithm function with base 2 resulting a logarithm with base 2 for number x.
