METHOD FOR TRANSMITTING UPLINK IN UNLICENSED BAND AND DEVICE USING SAME

摘要

Provided are a method for transmitting uplink in an unlicensed band and a device using the same. The device performs a clear channel assessment (CCA) inside a transmission window in an unlicensed band to thereby confirm whether a channel is idle. When the channel is idle, the device transmits an uplink transmission block inside the transmission window in the unlicensed band.
