Abstract: According to an embodiment of the present disclosure, a terminal may store a time correction value acquired from an RA response message during an RRC layer connection to a base station, receive, from the base station, an uplink resource allocation message including an uplink resource allocated to the terminal, after the RRC layer connection to the base station is released, and when an RRC layer connection to the base station is determined, establish the RRC layer connection to the base station without transmitting an RA preamble message, on the basis of the stored time correction value and the allocated uplink resource.

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 disclosure can be applied to an intelligent service (for example, smart home, smart building, smart city, smart car or connected car, health care, digital education, retail, security and safety-related services, and the like) on the basis of 5G communication technology and IoT-related technology. According to an embodiment of the present invention, a method by which a base station transmits a signal in a wireless communication system comprises the steps of: transmitting, to a terminal through at least one beam, at least one beam index including information on beam direction; receiving, from the terminal, a preferred beam index determined by the terminal; determining a channel matrix between the base station and the terminal on the basis of the preferred beam index; and allowing the base station to transmit a signal to the terminal on the basis of the channel matrix. The study has been performed under the support of the “Government-wide Giga KOREA Business” of the Ministry of Science, ICT and Future Planning.

Abstract: The present disclosure relates to a 5G or pre-5G communication system for supporting a higher data transmission rate beyond a 4G communication system such as LTE. The present invention relates to a method for guaranteeing quality of service in a wireless communication system. More particularly, a method of a base station according to an embodiment of the present invention comprises the steps of: identifying at least one non-Guaranteed bit rate (GBR) bearer configured for an arbitrary communication device; determining whether to guarantee a specific bit rate to the non-GBR bearer, on the basis of at least one of QoS class identifier (QCI) information, allocation and retention priority (ARP) information, and subscriber profile identifier (SPID), which are received from a core network node for the non-GBR bearer; and performing scheduling for the non-GBR bearer on the basis of the determination.

Abstract: The present disclosure relates to a pre-5th-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4th-Generation (4G) communication system such as long term evolution (LTE). According to various embodiments of the disclosure, a base station in a wireless communication system may include at least one transceiver and at least one processor operably coupled with the at least one transceiver, wherein the at least one processor may be configured to receive channel information regarding a plurality of carriers which are set in a terminal, from the terminal, distribute buffer occupancy (BO) of the terminal to the plurality of carriers by sequentially determining buffer usage for each of the plurality of carriers of the terminal based on the channel information, and allocate resources based on the buffer usage.
