Abstract

In a method for transmitting data in a wireless communication system supporting a low latency service according to the present invention, a method performed by a first UE comprises transmitting to an eNB an urgent signal (US) for informing of occurrence of an event related to an urgent situation; receiving from the eNB a response to the urgent signal through two PHICH (Physical HARQ Indication Channel) resources; and transmitting to the eNB urgent data including detailed information related to the occurred event on the basis of the received response, wherein each PHICH resource is determined by a Physical Resource Block (PRB) index of the resource to which the urgent signal is transmitted.

Dependent claims

A method for transmitting and receiving data in a wireless communication system, the method performed by a user equipment (UE) and comprising:

transmitting and receiving the data with an evolved Node B (eNB) through a radio frame,
wherein the radio frame includes a downlink (DL) radio frame and an uplink (UL) radio frame,
wherein the radio frame includes a legacy transmission time interval (TTI) and a short TTI,
wherein the legacy TTI includes two slots,
wherein each slot included in the legacy TTI includes a first short TTI and a second short TTI,
wherein the first short TTI and the second short TTI include a control region to which a control channel is allocated and a data region to which a data channel is allocated,
wherein downlink control information (DCI) related to uplink transmission of the first short TTI and the second short TTI is allocated to a control region of the first short TTI belonging to the downlink radio frame, and
wherein, when a highest physical resource block (PRB) index of the first short TTI is allocated as highest PRB index of a frequency band configured for the UE, a lowest PRB index of the second short TTI is allocated consecutively to the highest PRB index of the first short TTI.
