Abstract: As one of energy saving mechanisms for a new radio access technology (NR), a power saving state may be defined according to the present invention. More specifically, a user equipment (UE) enters an active state, monitors a first radio frequency (RF) bandwidth for the active state, enters the power saving state, and monitors a second RF bandwidth, which is restricted to M MHz within the first RF bandwidth, for the power saving state.

Abstract: A method for a transmission-side device to transmit a signal in a wireless communication system is disclosed. To this end, the transmission-side device forms a multiplexed block by multiplexing a primary synchronization signal (PSS), a secondary synchronization signal (SSS) and a physical broadcast channel (PBCH) signal in time and frequency domains, wherein the PSS and the SSS form a synchronization signal (SS) by being multiplexed by the time-division multiplexing (TDM) method, and the SS and PBCH signals form the multiplexed block by being multiplexed by the TDM or frequency-division multiplexing (FDM) method.

Abstract: Disclosed in the present application is a method for receiving by a terminal a multicast signal in a wireless communication system. Specifically, the method comprises the steps of: attempting to receive, from a network, a control signal for scheduling a multicast signal; receiving the multicast signal from the network and performing decoding on the basis of the control signal; and transmitting a data negative acknowledgement signal to the network when the decoding of the multicast signal fails, wherein a control negative acknowledgement signal is transmitted to the network when the reception of the control signal has failed.

Abstract: The transmission apparatus maps a plurality of code blocks obtained from data to a time-frequency resource, and transmits the plurality of code blocks therefrom. The time-frequency resource comprises L number of time symbols in the time domain, where L is an integer greater than 1. Each of the L number of time symbols comprises one or more different code blocks from among the plurality of code blocks. The plurality of code blocks is mapped in the time-frequency resource so that one complete code block is one time symbol.
