This application discloses a remote apparatus, a base station, a random access method, a storage medium, and a program product, and relates to the field of communications technologies. The remote apparatus includes a radio frequency apparatus and a baseband apparatus, where the baseband apparatus is configured to perform partial or total physical layer protocol processing on data of UE, and respond to a random access preamble sent by the UE. In this application, after receiving the random access preamble of the UE, the remote apparatus may directly respond to the random access preamble by using the baseband apparatus, and does not need to send the random access preamble to a centralized control apparatus, so that the centralized control apparatus responds to the random access preamble.
