A wireless device receives one or more downlink control information. The one or more downlink control information indicate negative acknowledgements. The negative acknowledgements are for one or more first code block groups of a first transport block corresponding to a first hybrid automatic repeat request (HARQ) process and one or more second code block groups of a second transport block corresponding to a second HARQ process. The wireless device determines that a size of a first configured grant is sufficient to retransmit the one or more first code block groups and the one or more second code block groups. Based on the determining, the wireless device retransmits, via radio resources of the first configured grant, the one or more first code block groups and the one or more second code block groups.
