Abstract: The present specification relates to a method and a device for randomizing a signal that satisfies ε-differential privacy, the method receiving a signal having a specific value of a bit error rate (BER), and generating a randomized signal on the basis of the signal, and then transmitting the randomized signal to a machine learning server. If a differential privacy mechanism is provided in a physical layer, true randomness of a wireless channel causes security to be less vulnerable than that of a pseudo random mechanism provided by an application, communication delay is reduced, and the power of the device can be reduced.

Abstract: Provided are a method and equipment for performing device-to-device communication by sharing an uplink resource and a sidelink resource in a wireless communication system. Particularly, a first terminal transmits a reference signal to a base station. The first terminal receives a downlink control signal from the base station. The downlink control signal includes beam limiting information indicating a beam, which is not used for reducing interference with an uplink signal, when the first terminal transmits a sidelink signal. The first terminal transmits the sidelink signal to a second terminal by using beams excluding the beam indicated by the beam limiting information. The sidelink signal is transmitted through a resource pool in which the uplink resource and the sidelink resource are overlapped in time and frequency domains.

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.
