A wireless device receives one or more messages. The one or more messages comprise a sidelink priority for a sidelink transmission via a sidelink resource pool; a first priority threshold for the sidelink resource pool; and a second priority threshold for the sidelink resource pool. The sidelink transmission overlapping with a configured uplink transmission is transmitted based on comparing the sidelink priority with: the first priority threshold in response to the configured uplink transmission being a first priority class; and the second priority threshold in response to the configured uplink transmission being a second priority class.
