Abstract: Methods and apparatuses are provided in which a user equipment (UE) receives a system information block (SIB) from a network. The UE identifies at least one downlink (DL) period based on a first uplink (UL)/DL configuration included in the SIB. The UE monitors a physical downlink control channel (PDCCH) during the at least one DL period using a discontinuous reception (DRX) operation. The UE obtains downlink control information (DCI) for indicating at least one second UL/DL configuration as a format for one or more time intervals from the monitored PDCCH. The UE determines the format for the one or more time intervals based on the obtained DCI. The monitoring of the PDCCH includes monitoring the PDCCH in an active time of a DRX cycle. The active time includes a time when the UE performs continuous reception.

Abstract: Disclosed are a communication technique for merging, with IoT technology, a 5G communication system for supporting a data transmission rate higher than that of a 4G system and a system therefor. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. Disclosed is a method by which a terminal performs a random access, comprising: receiving, from a serving base station, a handover command including configuration information indicating a dedicated random access resource and a common random access resource determining whether to perform a random access by using at least one of the dedicated random access resource and the common random access resource according to predetermined criteria; and performing the random access on the basis of the determination result.
