Problems solved by technology

However, when the transmission power is too large in the downlink transmission to a different UE, it causes unnecessary interference to the UE
Also, if the base station does not perform downlink transmission to a different UE due to concern about interference even though there is little interference to the UE, resources are wasted

Abstract

Provided are a method for transmitting a physical uplink shared channel (PUSCH) of a terminal in an unlicensed band and a device using the same method. The method comprises: receiving first information indicating a symbol index and second information indicating a length; and transmitting, in at least one slot capable of transmitting the PUSCH, the PUSCH by using a time resource determined on the basis of the first information and the second information.

Description

technical field [0001] The present disclosure relates to wireless communication, and more particularly, to a method for a UE to transmit an uplink shared channel in an unlicensed frequency band and a device using the method. Background technique [0002] A wireless communication system is a multiple-access system that supports communication with multiple users by sharing available system resources (eg, bandwidth, transmission power, etc.). Examples of multiple-access systems include Code Division Multiple Access (CDMA) systems, Frequency Division Multiple Access (FDMA) systems, Time Division Multiple Access (TDMA) systems, Orthogonal Frequency Division Multiple Access (OFDMA) systems, Single Carrier Frequency Division Multiple Access ( SC-FDMA) system, multi-carrier frequency division multiple access (MC-FDMA) system, etc. [0003] figure 1 An example of a 5G usage scenario to which the technical features of the present disclosure are applicable is illustrated. figure 1 T...
