    Abstract: A communication method and system for converging a fifth generation (5G) communication system for supporting higher data rates beyond a fourth generation (4G) system with a technology for internet of things (IoT) includes intelligent services based on the 5G communication technology and the IoT-related technology. A method by a terminal for transmitting uplink data in a wireless communication system comprises receiving downlink control information for scheduling of uplink transmission in a cell from a base station and transmitting the uplink data to the base station on the supplementary uplink if the indicator indicates the scheduling of the uplink transmission is associated with the supplementary uplink in the cell. The downlink control information includes an indicator indicating whether the scheduling of the uplink transmission is associated with a supplementary uplink in the cell.

    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 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 disclosure, a terminal of a communication system can transmit, to a base station, information related to a mobile characteristic or a channel time-varying characteristic, receive information related to reference signal transmission from the base station, generate a reference signal on the basis of the information related to reference signal transmission, and transmit the reference signal to the base station.

    Abstract: A communication system is provided. The communication system supports higher data rates Beyond 4th-Generation (4G) communication system such as Long Term Evolution (LTE). A first apparatus in a wireless communication system is provided. The apparatus includes an antenna array, at least one transceiver, and at least one processor. The transceiver is configured to transmit signals by using a beam set, and receive a signal for indicating at least one beam in the beam set from a second apparatus. The processor is configured to determine an auxiliary beam pair, based on the at least one beam. The transceiver is configured to transmit reference signals to the second apparatus by using the auxiliary beam pair, and receive feedback information relating to the auxiliary beam pair from the second apparatus. The at least one processor is configured to determine, based on the feedback information, a communication direction relating to the second apparatus.
