    Abstract: 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.

    Abstract: A communication technique for convergence between an IoT technology and a 5th generation (5G) communication system for supporting a higher data transmission rate beyond a 4th generation (4G) system, and a system thereof is provided. The method includes intelligence services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail businesses, security and safety related services, and the like.) On the basis of a 5G communication technology and an IoT-related technology. A method includes determining a scheduling-related parameter for at least one user, and transmitting scheduling information indicating the scheduling-related parameter to a radio unit (RU), wherein the scheduling information includes a first section extension field including information relating to a user equipment identifier (ueID) related to the at least one user, and a second section extension field including information relating to a number of ueIDs corresponding to each user.

    Abstract: The present disclosure relates to technologies for sensor networks, machine-to-machine (M2M) communication, machine-type communication (MTC), and the Internet of Things (IoT). The present disclosure may be used for intelligent services based on these technologies (smart homes, smart buildings, smart cities, smart or connected cars, healthcare, digital education, retail business, security and safety, and the like). For sending a payload to multiple users through OFDMA in a wireless LAN system, it is difficult to efficiently allocate resources for OFDMA by using the resource allocation configuration of the existing PPDU. Hence, there is proposed a new PPDU including a first field and a second field.
