Abstract: Disclosed is a method for a wireless device for transmitting a random-access preamble. The method may comprise the steps of: generating a sequence of a random-access preamble; and mapping the sequence of a random-access preamble to one sub-carrier wave from among 12 sub-carrier waves of a frequency domain. The mapping step may comprise the step for carrying out a first hop between a plurality of sub-regions. Each sub-region may comprise a previously set number of sub-carrier waves. The mapping step may additionally comprise the step for carrying out a second hop from among the sub-carrier waves within any one sub-region.

Abstract: Disclosed is a method for a terminal reporting channel status information (CSI) to a base station in a wireless communication system. The method comprises receiving, via an upper later, information associated with a single CSI process comprising a firs enhanced multiple input multiple output (eMIMO) type and a second eMIMO type; reporting, to a base station, a first CSI updated on the basis of a first channel status information-reference signal (CSI-RS) corresponding to the first eMIMO type received from a first subframe; and receiving, from the base station, a triggering message of a second CSI calculated on the basis of a second CSI-RS corresponding to the second eMIMO type from a second subframe.

Abstract: Provided are a method and apparatus for reporting channel state information (CSI) by a user equipment in a wireless communication system. A user equipment may receive first configuration information related to the reporting of CSI from a base station receive, and may report CSI to the base station based on the first configuration information. In this case, the first configuration information includes resource configuration information related to a physical uplink shared channel (PUCCH) resource for reporting the CSI. The PUCCH resource may be configured for each of at least one bandwidth part (BWP) activated for the reporting of the CSI.

Abstract: The present invention relates to a wireless access system supporting an unlicensed band and provides methods for performing a channel access process for transmitting different types of signals, and devices supporting the same. According to one embodiment of the present invention, a method for transmitting different types of signals in a wireless access system supporting an unlicensed band can comprise the steps of: performing a first channel process (CAP) for transmitting a first type of signal; and transmitting a transmission burst including the first type of signal through the unlicensed band if it is determined that a serving cell (SCell) of the unlicensed band is in an idle state after performing the first CAP. At this time, at least one of first parameters for performing the first CAP can be set to be value less than that of second parameters for performing a second CAP for transmitting a second type of signal.
