The disclosure relates to a communication technique for combining a 5generation (5G) communication system with an IoT technology to support a higher data transmission rate than a 4generation (4G) system, and a system thereof. The disclosure may be applied to intelligent services (for example, services related to smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail business, security and safety, etc.) based on a 5G communication technology and an IoT-related technology. A method and an apparatus for 5G migration in a frequency interference combination band and, more specifically, to a scheduling method and apparatus for interference control and efficient resource utilization in a mobile communication system supporting a carrier aggregation technology, a dual connectivity or multi-connectivity technology, or the like which simultaneously uses a plurality of frequency resources are provided.

Method and apparatus for 5G migration in frequency interference combination band

Provided are a method and a Base Station (BS) for transmitting a control channel and a method and a User Equipment (UE) for receiving a control channel in a wireless communication system. The BS includes: a transceiver; and at least one processor configured to control the transceiver to receive Beam State Information (BSI) from the UE through at least one first beam, identify a second beam, based on the BSI, and control the transceiver to transmit a first BSI request to the UE through the second beam, identify a third beam, based on information on the at least one first beam, and determine whether control the transceiver to transmit the control channel to the UE through the third beam.

Method and apparatus for transmitting control channel in wireless communication system

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.

Signal transmission method and device using beamforming in wireless communication system

A pre-5-Generation (5G) or 5G communication system is provided for supporting higher data rates than in 4-Generation system. An apparatus of a base station includes: at least one transceiver and at least one processor operatively connected to the transceiver. The transceiver receives channel quality information from a terminal. The processor obtains a first modulation and coding scheme (MCS) level and a number of first resource blocks based on the channel quality information, determines a power boosting value for applying a second MCS level indicating a higher modulation order or a higher code rate than the first MCS level, obtains, based on the power boosting value, a number of second resource blocks corresponding to a transport block size (TBS) value greater than a TBS value corresponding to the number of the first resource blocks in the first MCS level and transmits downlink data based on these determinations.

Apparatus and method for allocating resources in wireless communication system

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.
