Claim 19:
20. A system comprising:
a base station comprising one or more first processors and first memory storing first instructions that, when executed by the one or more first processors, cause the base station to:
transmit 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; and
a wireless device comprising one or more second processors and second memory storing second instructions that, when executed by the one or more second processors, cause the wireless device to:
receive the one or more configuration parameters indicating the PUSCH resource for transmission of the MsgA payload of the contention-free two-step random-access procedure;
receive, 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, clear the PUSCH resource of the contention-free two-step random-access procedure.
