METHOD FOR TRANSMITTING SIGNAL ON BASIS OF CLEAR CHANNEL ASSESSMENT IN UNLICENSED BAND CHANNEL, AND MOBILE COMMUNICATION SYSTEM |
摘要 |
Disclosed is a 5G or pre-5G communication system for supporting a data transmission rate higher than that of a 4G communication system such as LTE. Disclosed are: a method for transmitting a signal in an unlicensed band channel on the basis of a counter reduction in the unlicensed band channel of a mobile communication system and a clear channel assessment (CCA) of the channel; and a mobile communication system, and according to an embodiment of the present invention, the method for transmitting a signal in an unlicensed band channel on the basis of a counter reduction in the unlicensed band channel of a mobile communication system and a clear channel assessment (CCA) of the channel comprises the steps of: reducing the counter and performing a CCA for the channel, during a first period of transmitting a discovery signal and data; storing the reduced counter when a second period of transmitting only the discovery signal without the data is started; reducing the counter by using the stored counter and performing the CCA for the channel when a third period of transmitting the discovery signal and the data is started; and transmitting the discovery signal or the data on the channel on the basis of the counter value. |
