A wireless device may transmit a first message, for a random access procedure, including a contention resolution identifier of the wireless device. The wireless device may receive, via a first slot indicated by downlink control information (DCI), a first response of the first message. The first response may include the contention resolution identifier and indicate a slot offset and a start symbol. The wireless device may receive a second response of the first message from the start symbol of a second slot, wherein the second slot is based on a time offset and the slot offset with respect to the first slot.
