1. A method comprising:
receiving, by a wireless device, one or more configuration parameters indicating a physical uplink shared channel (PUSCH) resource for transmission of a message A (MsgA) payload of a contention-free two-step random-access procedure;
receiving, from a radio resource control (RRC) layer of the wireless device, a request to reset a medium access control (MAC) layer of the wireless device; and
in response to the request and based on the one or more configuration parameters indicating the PUSCH resource for the MsgA transmission, clearing the PUSCH resource of the contention-free two-step random-access procedure.
