摘要：
A wireless device receives one or more configuration parameters for uplink bandwidth parts (BWPs) of a cell. A first preamble, for a random-access procedure, is transmitted via a first uplink BWP of the uplink BWPs. A random-access response comprising a backoff indicator is received. A backoff window associated with the backoff indicator is started. A second uplink BWP of the uplink BWPs, that is different from the first uplink BWP, is selected for transmission of a second preamble during the backoff window. The wireless device transmits, via the second uplink BWP and based on the selecting, the second preamble for the random-access procedure.
