Title: METHOD FOR TRANSMITTING CONTROL SIGNAL AND CHANNEL IN MOBILE COMMUNICATION SYSTEM USING UNLICENSED BAND
Abstract:
The present disclosure relates to a communication method which fuses a 5G communication system with IoT technology to support a higher data transfer rate than a 4G system, and a system thereof. The present disclosure may be applied to intelligent services such as smart homes, smart buildings, smart cars or connected cars, healthcare, digital education, retail business, security and safety services, etc., based on 5G communication technologies and IoT related technologies. More specifically, a method for operating a base station in a mobile communication system using an unlicensed band, according to the present invention, comprises the steps of: transmitting and receiving data to and from a terminal in a first cell; establishing a signal transmission timing related to a start symbol of a slot of a subframe for a second cell; occupying a resource by executing a sensing operation in a band corresponding to the second cell; and executing communication with the terminal in the occupied resource on the basis of the established signal transmission timing.
