Abstract: The present disclosure relates to a communication technique and system thereof that fuse a 5G communication system with IoT technology for supporting a higher data rate than a 4G system. The present disclosure may be applied to intelligent services (e.g., smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail, security and safety related services, etc.) on the basis of 5G communication technology and IoT related technology. A method for controlling a base station according to one embodiment of the present invention may comprise the steps of: generating a first packet including data to be transmitted to a terminal on an unlicensed band; determining whether a channel sensing for using the unlicensed band is completed when the generation of the first packet is completed; and as a result of the determination, when the channel sensing for using the unlicensed band is not completed, omitting a transmission of the first packet.

Abstract: The disclosure relates to a 5G or pre-5G communication system for supporting higher data transmission rates than 4G communication systems such as LTE systems. According to the disclosure, a method for performing beamforming by a base station in a wireless communication system comprises obtaining transmission time proportions allocated to a plurality of beam directions and performing beamforming to send control information in the plurality of beam directions based on the obtained transmission time proportions. A base station configured to perform beamforming in a wireless communication system, includes a transceiver configured to perform beamforming communication with a UE, and a processor configured to obtain transmission time proportions allocated to each of a plurality of beam directions, and control beamforming for sending control information based on the obtained transmission time proportions.

Abstract: The present disclosure provides methods and apparatuses for transmitting data, by a base station, in an unlicensed frequency. A method according to a representative embodiment includes: transmitting a first signal for determining whether a data transmission is possible in an unlicensed frequency band; transmitting a second signal for reserving a data transmission in the unlicensed frequency band when the data transmission in the unlicensed frequency band is possible; and transmitting first data to a terminal through the unlicensed frequency band after transmitting the second signal. In an aspect, the base station determines whether other communication devices do not use the unlicensed frequency band, and transmits a channel reservation signal having a period shorter than a resource allocation period during a predetermined period of time, thereby pursuing coexistence with other communication devices and improving the performance of a communication system at the same time.
