    Abstract: The present invention relates to a wireless access system supporting millimeter wave (mmWave), and provides a transmission/reception beam scanning method, a channel state information feedback method, and devices supporting the same. According to an embodiment of the present invention, a method for scanning a transmission/reception beam by a millimeter wave (mmWave) terminal in a wireless access system supporting mmWave may comprise the steps of: performing long term beam scanning in period N; transmitting feedback information including a first transmission beam identifier (Tx beam ID) acquired through the long term beam scanning to a mmWave base station; receiving an upper layer signal including reception beam scanning configuration information allocated for short term beam scanning; and performing the short term beam scanning in a reception beam scanning area on the basis of the reception beam scanning configuration information.

    Abstract: A method and apparatus for transmitting and receiving codebook-based channel state information in a wireless communication system are disclosed. A method of performing CSI report by a UE in a wireless communication system according to an embodiment of the present disclosure may comprise: receiving, from a base station, configuration information on the channel state information report; receiving, from the base station, at least one channel state information-reference signal (CSI-RS) based on the configuration information; and transmitting, to the base station, CSI calculated based on the at least one CSI-RS and priority-related information for omission of the corresponding CSI. Here, the priority-related information may be determined based on strongest coefficient information related to the corresponding CSI.
