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. The present invention proposes a method and a device, of a terminal using a millimeter wave, for selecting an antenna in order to transmit/receive a signal in a next-generation communication system. According to the present invention, the terminal may select, on the basis of information acquired from a sensor, an antenna having no physical contact or positioned in a relatively high position.

Terminal method and device for switching antenna in real-time

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). According to various embodiments, a device of a terminal, in a wireless communication system, can include at least one processor and at least one transceiver operatively coupled to the at least one processor. The at least one transceiver configured to receive, from a base station, a first signal transmitted using a first beam of the base station and including system information and receive, from the base station, a second signal transmitted using a second beam of the base station and including the system information, and the at least one processor is configured to decode the second signal in combination with the first signal, thereby enabling the system information to be acquired.

Device and method for acquiring system information by decoding signals in wireless communication system

The present disclosure is research (No. GK17N0100, Millimeter-wave 5G Mobile Communication System Development) having been performed with support from 'The Cross-Ministry Giga KOREA Project' funded by the government (Ministry of Science and ICT) in 2017. Disclosed are: a communication technique for merging, with IoT technology, a 5G communication system for 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. According to the present invention, a method by which a transmitter transmits data comprises a step of transmitting a data packet to a receiver, receiving hybrid ARQ (HARQ) feedback information based on a decoded result of the data packet, generating a data packet to be re-transmitted on the basis of the HARQ feedback information, and transmitting, to the receiver, the data packet to be re-transmitted, wherein the HARQ feedback information can include acknowledgment (ACK) or negative-acknowledgment (NACK) and information including a HARQ status of the data packet.

Method and device for efficient HARQ operation

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). According to various embodiments, a device of a terminal, in a wireless communication system, can comprise at least one processor and at least one transceiver operatively coupled to the at least one processor. The at least one transceiver configured to receive, from a base station, a first signal transmitted using a first beam of the base station and including system information and receive, from the base station, a second signal transmitted using a second beam of the base station and including the system information, and the at least one processor is configured to decode the second signal in combination with the first signal, thereby enabling the system information to be acquired.

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 communication technique that fuses, with IoT technology, a 5G communication system for supporting higher data transmission rates than 4G systems, and a system thereof. The present disclosure can be applied to intelligent services (such as smart home, smart building, smart city, smart car, or connected car, health care, digital education, retail business, security and safety-related services, etc.) on the basis of 5G communication technology and IoT-related technology. The present disclosure relates to a method and an apparatus for performing synchronization using previous synchronization information where the previous synchronization information may be information about synchronization that is lost when the terminal turns off a radio frequency module to enter a low power mode.

Method and apparatus for performing enhanced synchronization in wireless 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.
