    Abstract: The present disclosure relates to a 5th generation (5G) or pre-5G communication system for supporting a higher data transmission rate beyond a 4th generation (4G) communication system such as long term evolution (LTE). The present disclosure is to transmit a downlink control channel in a wireless communication system. An operation method of a base station comprises the steps of: transmitting information on a configuration of a control channel using a plurality of transmission beams; transmitting control information through the control channel, using the plurality of transmission beams; and transmitting data through a data channel allocated by the control information, using at least one of the plurality of transmission beams.

    Abstract: The present disclosure relates to a communication technique which combines IoT technology with a 5G communication system for supporting a higher data transfer rate than existing 4G systems, and a system thereof. The present disclosure can be applied to an intelligent service (for example, a smart home, a smart building, a smart city, a smart car or a connected car, and services related to health care, digital education, retail business, security and safety, etc.) on the basis of 5G communication technology and IoT-related technology. The present method provides a power headroom information transmission method of a terminal, the headroom information transmission method including: a step of determining whether to transmit second power headroom information, on the basis of information about each beam included in first power headroom information, in a wireless communication system supporting beamforming; and a step of transmitting the second power headroom information to a base station when the transmission of the second power headroom information is determined.
