Abstract:
According to one embodiment of the present invention, a method by which a wireless communication device including a plurality of antennas transmits and receives a wireless signal in an unlicensed band in a wireless communication system comprises the steps of: performing a clear channel assessment (CCA) by using the plurality of antennas for a predetermined time interval in the unlicensed band; and transmitting the wireless signal through the unlicensed band when it is determined that the unlicensed band is in an idle state in which the unlicensed band is not occupied by other wireless communication devices, wherein the step of performing the CCA can comprise the steps of: acquiring one reference value by using energy sensing indicators (ESIs) measured through the plurality of antennas; and comparing the reference value with a CCA threshold value so as to determine whether the unlicensed band is in an idle state.

Claim (Index 16):
A wireless communication apparatus for transmitting and receiving a wireless signal in an unlicensed band in a wireless communication system, comprising:\n an RF (Radio Frequency) unit configured to transmit and receive a wireless signal; and a processor configured to control the RF unit, wherein, when performing CCA (Clear Channel Assessment) using a plurality of antennas for a predetermined time duration in the unlicensed band, the wireless communication apparatus is configured to: obtain one reference value using energy sensing indicators (ESIs) measured through the plurality of antennas, determine whether the unlicensed band is idle state by comparing the reference value with a CCA threshold, and transmit a wireless signal through the unlicensed band when the unlicensed band is determined as an idle state where the unlicensed band is unoccupied by other wireless communication apparatuses.
