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 method of transmitting uplink control information (UCI) by a user equipment in a wireless communication system, includes the steps of receiving downlink control information (DCI) indicating a transmission time of the UCI through a prescribed frequency band in a first subframe, receiving a downlink data based on the DCI, and transmitting UCI associated with the downlink data in a second subframe based on the indicated transmission time of the UCI. In this case, the prescribed frequency band on which the DCI is transmitted is configured by a plurality of DCCUs (downlink control channel units) for transmitting the DCI, and the UCI may be transmitted on an UCCU (uplink control channel unit) in the second subframe, a frequency band of the first UCCU being same as a frequency band corresponding to a DCCU of a lowest frequency among the plurality of DCCUs.
