A pre-5-Generation (5G) or 5G communication system for supporting higher data rates Beyond 4-Generation (4G) communication system such as Long Term Evolution (LTE) is provided. The device of a radio unit (RU) of a base station in a wireless communication system includes at least one transceiver and at least one processor coupled to the at least one transceiver, wherein the at least one processor is configured to receive a first control message including a section extension field from a digital unit (DU) via a fronthaul interface, identify additional information based on the section extension field, and acquire a beamforming weight based on the additional information, wherein the first control message is configured to schedule a terminal in a control plane.

Device and method for fronthaul transmission in wireless communication system

A pre-5th-Generation (5G) or 5G communication system for supporting higher data rates Beyond 4-Generation (4G) communication system such as Long Term Evolution (LTE) is provided. The device of a radio unit (RU) of a base station in a wireless communication system includes at least one transceiver and at least one processor coupled to the at least one transceiver, wherein the at least one processor is configured to receive a first control message including a section extension field from a digital unit (DU) via a fronthaul interface, identify additional information based on the section extension field, and acquire a beamforming weight based on the additional information, wherein the first control message is configured to schedule a terminal in a control plane.

The present disclosure relates to a communication technique for converging IoT technology with a 5G communication system for supporting a higher data transmission rate beyond a 4G system, and a system therefor. The present disclosure may be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart car or connected car, health care, digital education, retail business, a security and safety-related service, etc.) on the basis of 5G communication technology and IoT-related technology. A communication method of a terminal of a mobile communication system, according to one embodiment of the present specification, comprises the steps of: acquiring moving speed information of a terminal; determining a reception beam candidate group on the basis of the moving speed information; and determining a reception beam, in the reception beam candidate group, for receiving a signal.

Beam operation method and device at terminal of beamforming communication system

The present disclosure relates to a pre-5-Generation (5G) or 5G communication system to be provided for supporting higher data rates Beyond 4-Generation (4G) communication system such as Long Term Evolution (LTE). The present disclosure relates to an apparatus and a method for wireless communication. The method may include: measuring beam pairs using signals transmitted from another apparatus using a plurality of carriers; determining a beam pair for the plurality of carriers based on measurement values for the beam pairs; and transmitting information indicating a transmit beam of the beam pair, to the other apparatus.

Apparatus and method for selecting beam in wireless communication system

Disclosed is a 5G or pre-5G communication system to be provided so as to support a data transmission rate higher that of a 4G communication system such as LTE. According to one embodiment of the present invention, a method for receiving data in a wireless communication system by using a channel bonding scheme can comprise the steps of: monitoring reception of a preamble in a preset minimum bandwidth of the entire channel-bondable bandwidth; acquiring data transmission bandwidth information and switching interval time information from the preamble when the preamble is to be received; and receiving data by switching from the minimum bandwidth to the data transmission bandwidth for the acquired switching interval time.

Method and device for saving power of electronic device in wireless communication system

Provided are a method and apparatus for estimating and correcting the phase error in 5G or pre-5G communication systems providing much higher data rates compared to existing 4G communication systems including LTE systems. The existing phase error estimation scheme using a cyclic prefix in the time domain may fail to prevent performance degradation due to inter-carrier interference. In the present invention, it is possible to enhance reception performance of the receiver by estimating and correcting the phase error multiple times within a symbol using a time domain signal and by reducing the influence of inter-carrier interference.
