1. A network node comprising transceiver circuitry and control circuitry, whereby the transceiver circuitry, under control of the control circuitry, is configured to:
initiate transmission of first data to a first mobile device and second data to a second mobile device, the first data corresponding to a transport block (TB), the TB comprising a plurality of code block groups (CBGs), each of the plurality of CBGs corresponding to a respective set of code blocks (CBs),
transmit, to the first mobile device, an indication of preemption granularity;
transmit, to the first mobile device, a preemption indicator that contains information identifying transmission resources that were allocated for transmission of the first data but that were preempted to transmit the second data;
receive hybrid automatic repeat request (HARQ) feedback for the first data, wherein a respective HARQ acknowledgement (ACK) or negative acknowledgement (NACK) is provided for each of the plurality of CBGs comprised in the TB, a HARQ ACK is provided for a respective CBG if each of the CBs of the respective CBG is successfully received, and a HARQ NACK is provided for a respective CBG if at least one of the CBs comprised in the respective CBG is not successfully received;
transmit, to the first mobile device, downlink control information (DCI) indicating a retransmission, wherein the retransmission corresponds to a portion of the first data, wherein the portion of the first data corresponds to at least one CBG of the plurality of CBGs comprised in the TB, the DCI comprises an indication of the at least one CBG, and the DCI indicates a time window for receiving the at least one CBG at the mobile device; and
transmit, to the first mobile device, the at least one CBG in accordance with the DCI.
