Systems, devices, and techniques for random access in a wireless communication network are described. A described technique performed by a user equipment (UE) includes transmitting a first message of a two-step random access procedure to a node of a wireless communication network; receiving, in response to the first message, a downlink control information (DCI) message via a physical downlink control channel (PDCCH) and a second message of the two-step random access procedure via a physical downlink shared channel (PDSCH) in accordance with the DCI message; determining, by the UE, a physical uplink control channel (PUCCH) resource based on the second message; and transmitting, by the UE, hybrid automatic repeat request-acknowledgement (HARQ-ACK) feedback for the second message on the determined PUCCH resource.
