Abstract: A method and device for dynamically allocating resources to a frequency band of a short transmission time interval (TTI) in a wireless communication system is provided. Specifically, a plurality of first downlink channels and a second downlink channel included in a subframe corresponding to one TTI are received, wherein the plurality of first downlink channels are received during sTTIs and the second downlink channel is received during the TTI. The plurality of first downlink channels are sequentially received. The plurality of first downlink channels are demodulated using control information included in a downlink control information (DCI) used for the second downlink channel and an RRC message. The control information and RRC message indicate frequency resources for the plurality of first downlink channels.

Abstract: The present specification relates to a method for transmitting uplink data (UL data) in a wireless communication system for supporting a low latency service, and the method executed by a first terminal is characterized by including the steps of: transmitting, to a base station, an urgent signal (US) for informing occurrence of an event related to an urgent situation; receiving, from the base station, a response to the urgent signal through two physical HARQ indication channel (PHICH) resources; and transmitting, to the base station, urgent data including detailed information related to the event that has occurred based on the received response. Each of the PHICH resources is determined by a physical resource block (PRB) index of a resource through which the urgent signal is transmitted.

Abstract: Disclosed is a method of transmitting a synchronization signal from a moving cell base station in a wireless communication system. The present invention includes mapping a moving cell synchronization signal sequence generated on a basis of a sequence assigned for a moving cell to a frequency region and transmitting the mapped moving cell synchronization signal sequence. Moreover, the moving cell synchronization signal sequence may be mapped to the frequency region different from a prescribed frequency region for transmitting a synchronization signal for a user equipment unsupportive of the moving cell.
