Abstract: Disclosed is a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system such as long term evolution (LTE). Disclosed is a method by which a terminal transmits a buffer status report (BSR) in a communication system, comprising the steps of: allocating an uplink resource from a base station; comparing the number of padding bits with a value obtained by summing the size of the BSR and the size of a sub-header of the BSR; and transmitting, to the base station according to the comparison result, the BSR including information indicating the presence or absence of a field representing a buffer size for at least one logical channel group (LCG).

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.

Abstract: Disclosed is a fifth generation (5G) or pre-5G communication system for supporting higher data transmission rates beyond fourth generation (4G) communication systems such as LTE systems. A data communication method includes receiving information about a reception rate of a signal from a second user equipment (UE) performing device-to-device (D2D) communication with a first UE, receiving location information about at least one of the first UE and the second UE, determining a data communication configuration for the D2D communication based on the reception rate information and the location information, and transmitting the determined data communication configuration to at least one of the first UE and the second UE.
