Patent ID: 11121836

Abstract:
Disclosed are a method for transmitting and receiving data in a wireless communication system and a device therefor. Specifically, a method for transmitting and receiving, by a user equipment, data in a wireless communication system supporting a short transmission time interval (TTI) may include: receiving, through at least one of a physical downlink control channel (PDCCH) depending on a radio frame structure based on a first TTI or a short PDCCH (sPDCCH) based on a second TTI, downlink control information related to the second TTI, wherein the number of symbols corresponding to the second TTI is smaller than the number of symbols corresponding to the first TTI; and receiving downlink data related to the second TTI through a short physical downlink shared channel (sPDSCH) depending on the radio frame structure based on the second TTI by using the downlink control information.
