Abstract: Provided are a method and equipment for transmitting uplink data by using a non-orthogonal code multiple access technique in a wireless communication system. Particularly, a terminal receives, from a base station, allocation information on physical resource blocks. The terminal acquires a spreading factor on the basis of the number of physical resource blocks included in the allocation information. The terminal determines a NoMA codebook set on the basis of the spreading factor. The terminal transmits uplink data generated on the basis of terminal-specific codewords included in the NoMA codebook set.

Abstract: The present invention provides a method for reducing a wireless positioning error by a target node in a multi-node system. Specifically, the method comprises the steps of: receiving information on the positions of anchor nodes from the anchor nodes, respectively; performing ranging of each of the anchor nodes; and when the target node is in a first state, transmitting information on the position of the target node to neighboring nodes except for each of the anchor nodes. The target node is capable of communicating with at least one of another target node, a target node related to an autonomous driving vehicle, a base station or a network.

Abstract: A method for a base station processing an in-band emission interference signal caused when the base station operating in a Full Duplex Radio (FDR) mode transceives signals using a Frequency Division Multiplexing (FDM) manner includes transmitting a downlink signal in a flexible downlink duration of an uplink band; and processing the in-band emission interference signal caused by transmission of the downlink signal in an uplink duration of the uplink band, wherein the processing of the in-band emission interference signal is performed by puncturing a corresponding resource of the uplink duration, wherein the resource on the downlink signal is transmitted is mirrored to the corresponding resource of the uplink duration from a Direct Current (DC) subcarrier as a reference.

Abstract: Provided is a method and device for transmitting uplink data by using a non-orthogonal code multiple access scheme in a wireless communication system. Specifically, a terminal supporting multiple layers receives an NoMA MCS index from a base station. The NoMA MCS index is selected from an NoMA MCS table on the basis of the quality of an uplink channel. The NoMA MCS table is defined in advance as a table including the NoMA MCS index, the number of multiple layers, and a modulation order. The number of multiple layers is determined according to the NoMA MCS index. The terminal transmits the uplink data configured on the basis of the NoMA MCS index, via the multiple layers.

Abstract: A user equipment (UE) receives UE group information indicating a first UE group to which the UE belongs, and transmits uplink (UL) data and a demodulation reference signal (DM-RS), which is for demodulating the UL data, on the basis of the UE group information. The DM-RS is transmitted by means of a first uplink demodulation reference signal (UL DM-RS) resource, which corresponds to the first UE group to which the UE belongs, among a plurality of UL DM-RS resources respectively corresponding to one or more UE groups.
