Abstract: A wireless device may transmit a data block based on a low latency operational mode. The device may then transmit a number of redundancy versions of the data block prior to determining whether an acknowledgement (ACK) has been received. In some examples the ACK may be an augmented ACK, which may be based on the number of redundancy versions received prior to successfully decoding the data block, and which may include an additional resource request. In some examples, the device may select an updated modulation and coding scheme (MCS) based on the augmented ACK. In some examples, the device may increase a number of frequency resources (e.g., component carriers) used for transmission based on the augmented ACK.

Abstract: A method for transmitting broadcast signals encodes service data corresponding to each of a plurality of physical paths and time interleaves the encoded service data by using each Time Interleaving (TI) block in an interleaving frame. In the time interleaving, each TI block includes a number of actual Forward Error Correction (FEC) blocks having the encoded service data, and further includes a number of virtual FEC blocks equal to a difference between the number of actual FEC blocks of each TI block and a maximum number of actual FEC blocks. The time interleaving is performed by acquiring a cell position by using a row index, a column index and a twisting parameter, and when the acquired cell position is corresponding to a virtual cell in the number of virtual FEC blocks, the acquired cell position is skipped during a reading operation of the time interleaving.
