    摘要: The present disclosure relates to 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). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method of operating a terminal for a slot aggregation signaling is provided. The method includes receiving control information including slot aggregation information from a base station, receiving data in aggregated slots based on the slot aggregation information from the base station, and transmitting an acknowledgement (ACK) corresponding to the data to the base station.

    摘要: Methods and apparatuses are provided in which a base station transmits a synchronization signal (SS) physical broadcast channel (PBCH) block (SSB) associated with a master information block (MIB) including first configuration information for a first control resource set (CORESET) associated with a common search space (CSS). System information is transmitted. The terminal obtains MIB based on the SSB, monitors first control information for scheduling the system information on the CSS based on a first aggregation level, and receives the system information based on the first control information. A radio resource control (RRC) connection is established with the terminal based on the system information. An RRC message is transmitted to the terminal including second configuration information for a second CORESET associated with a UE specific search space (USS), based on the RRC connection. The terminal monitors second control information for the UE on the USS based on a second aggregation level.

    摘要: The present disclosure relates a communication technique that fuses a 5G communication system supporting a higher data transmission rate following a 4G system with IoT technology and a system therefor. The present disclosure can be applied to intelligent services (e.g., smart homes, smart buildings, smart cities, smart cars or connected cars, health care, digital education, retail, security and safety related services, etc.) on the basis of 5G communication technology and IoT related technology. A method for transmitting a scheduling request (SR) of a terminal according to the present invention comprises the steps of: receiving SR configuration information; performing channel sensing of an unlicensed band in case that the SR is triggered in the unlicensed band; and waiting for SR transmission in case that a channel is occupied as a result of the channel sensing.

    摘要: A method of control information transmission for a terminal in a mobile communication system, and an apparatus therefor are provided. In the method of control information transmission, the terminal acquires unlicensed frequency channel occupancy information based on the control information received from a base station and transmits the unlicensed frequency channel occupancy information to other terminals operating on the same unlicensed frequency. The method of control information transmission includes receiving a first control information from a base station using a first radio communication protocol, acquiring channel occupancy information based on the first control information, and transmitting a second control information including the channel occupancy information to another terminal using a second radio communication protocol.
