Abstract: The present specification provides a method for transmitting data in a wireless communication system. More specifically, a method performed by a base station comprises the steps of: scrambling bits constituting at least one codeword by using a scrambling sequence; and transmitting, to a mobile station, data including the scrambled bits on a physical channel, wherein an initial value of the scrambling sequence is determined on the basis of a value calculated by floor calculation of a slot index and the number of slots in a radio frame. Due to these features, the initial value of the scrambling sequence can be kept the same during a specific time interval.

Abstract: A method of transmitting, by a user equipment (UE), power measurement information related to beam reporting in a wireless communication system includes: receiving downlink control information (DCI) triggering reporting of the power measurement information; receiving a downlink reference signal for reporting of the power measurement information; and transmitting, to a base station, power measurement information determined based on the received downlink reference signal. A minimum required time for reporting of the power measurement information is (i) calculated as the sum of a first minimum required time from the last timing of the downlink reference signal to a transmission timing of the power measurement information and a second minimum required time between DCI triggering the downlink reference signal and reception of the downlink reference signal or (ii) calculated based on a pre-configured threshold value related to reporting of the power measurement information.

Abstract: The present specification provides a method for transmitting and receiving an uplink channel in a wireless communication system, and a device therefor. Particularly, a method for transmitting an uplink channel by a terminal in a wireless communication system can comprise the steps of: receiving, from a base station, information indicating a first timing offset for channel state information (CSI) reporting and/or a second timing offset for transmitting uplink data; and transmitting an uplink data channel to the base station in a resource region configured in accordance with a specific timing offset value. The specific timing offset value can be set by applying the first timing offset and/or the second timing offset in accordance with the type of information allocated to the uplink data channel.
