Abstract: The disclosure relates to a fifth generation (5G) or sixth generation (6G) communication system for supporting a higher data transmission rate. A communication method, a user equipment (UE), a base station, and a storage medium are provided. The method includes receiving, by a UE, information related to physical random access channel (PRACH) resources, determining available PRACH resources in an energy saving state and/or non-energy saving state of a base station, and then transmitting a PRACH to the base station based on the available PRACH resources and the state of the base station. The method may reduce the amount of PRACH resources to be monitored by the base station, thereby achieving the purpose of saving power on the base station side.
