Abstract: A wireless device may determine whether a sidelink transmission has higher priority than an uplink transmission. The determination may be based on comparing a priority value of the sidelink transmission to a first priority threshold for ultra reliable low latency (URLLC) uplink transmissions in response to the uplink transmission being URLLC, and the determination may be based on comparing the priority value of the sidelink transmission to a second priority threshold for non-URLLC uplink transmissions in response to the uplink transmission being non-URLLC. Based on the determining, the wireless device may transmit at least one of the sidelink transmission or the uplink transmission.
