A base station transmits, to a wireless device, configuration parameters of a configured grant of an unlicensed cell. Based on the configured grant, the base station receives from the wireless device: one or more code block groups of a transport block, and a code block group transmission information indicating a presence of the one or more code block groups for the transport block. A downlink control information is transmitted that includes: a first field indicating that the base station received the code block group transmission information, and a second field indicating hybrid automatic repeat request feedback for each code block group of the one or more code block groups.
