Abstract: A method for transmitting signals by a user equipment (UE) in a multi input multi output (MIMO) communication system is disclosed. The method comprises steps of receiving two or more MIMO layer configurations per bandwidth part (BWP); receiving a medium access control (MAC) control element (CE) indicating a first MIMO layer configuration for a downlink reception via a first BWP and a second MIMO layer configuration for an uplink transmission via a second BWP among the two or more MIMO layer configurations; and transmitting and receiving signals based on the first and second MIMO layer configurations.

Abstract: Provided are a method for reporting a power headroom and an apparatus using the same. The apparatus computes and reports a power headroom for a physical uplink shared channel (PUSCH) that is transmitted in a first transmission period of a first band having a first subcarrier interval. The power headroom is computed on the basis of at least one second transmission interval of a second band having a second subcarrier interval which overlaps with the first transmission interval.

Abstract: One disclosure of the present specification proposes a method for receiving a Narrowband Reference Signal (NRS) by a Narrow band Internet of Things (NB-IoT) device. The method may comprise receiving the NRS on at least one or more orthogonal frequency division multiplexing (OFDM) symbols. The one or more OFDM symbols are in a time division duplex (TDD) subframe. If the TDD subframe corresponds to a TDD special subframe, the one or more OFDM symbols for receiving the NRS is determined based on which TDD special subframe configuration index among a plurality of TDD special configuration indexes is used by the TDD special subframe.

Abstract: Disclosed, in the present invention, are a method for transmitting, by a base station, a downlink signal in a wireless communication system supporting an unlicensed band, and a device for supporting the same. More particularly, in accordance with one embodiment of the present invention, when acknowledgment timing of each terminal (for example, an interval length from a time point of receiving downlink data to a time point of transmitting acknowledgment information for the downlink data) is set flexibly (or independently), a base station may determine a reference downlink resource for contention window size (CWS) adjustment by considering the acknowledgement timing and perform downlink signal transmission by adjusting CWS on the basis of the acknowledgment information received for the reference downlink resource.

Abstract: The disclosure of the present specification provides a method for transmitting, by a user device, hybrid automatic repeat request (HARQ) positive-acknowledgment (ACK)/negative-acknowledgment (NACK) information. The method may comprise the steps of: determining a channel coding scheme to be used for transmitting the HARQ ACK/NACK information through an uplink physical channel, on the basis of first information; and performing channel coding of the HARQ ACK/NACK information according to the determined channel coding scheme. The channel coding scheme may include at least one of a channel coding scheme, a cyclic redundancy check (CRC) architecture, a channel encoder size, and a modulation scheme.
