1. A method comprising:
receiving, by a wireless device, one or more messages comprising one or more configuration parameters for a cell, wherein the cell comprises:
a normal uplink (NUL) carrier;
a supplementary uplink (SUL) carrier; and
a downlink carrier comprising at least two downlink bandwidth parts (BWPs);
selecting, for a random-access procedure of the cell, an uplink carrier among the NUL carrier and the SUL carrier based on a measured quality of each downlink BWP of the at least two downlink BWPs, wherein the uplink carrier is the NUL carrier based on an average of the measured quality of each downlink BWP of the at least two downlink BWPs being equal or greater than an uplink carrier threshold; and
transmitting, via the NUL, a random-access preamble for the random-access procedure.
