1. A method comprising:
receiving, by a wireless device:
first configuration parameters of a first uplink carrier and a second uplink carrier of a first cell, wherein the second uplink carrier is a licensed carrier; and
second configuration parameters of a third uplink carrier and a fourth uplink carrier of a second cell, wherein the fourth uplink carrier is an unlicensed carrier;
receiving a first downlink control information (DCI) indicating switching from the first uplink carrier to the second uplink carrier;
receiving a second DCI indicating switching from the third uplink carrier to the fourth uplink carrier;
determining whether to transmit a confirmation for uplink carrier switching based on the uplink carrier switching being to the licensed carrier or the unlicensed carrier;
based on determining that the first DCI is for the licensed carrier:
switching from the first uplink carrier to the second uplink carrier; and
not transmitting the confirmation; and
based on determining that the second DCI is for the unlicensed carrier:
switching from the third uplink carrier to the fourth uplink carrier; and
transmitting the confirmation.
