Abstract: A method and device for determining the initial positions of a downlink data channel are provided. The method includes: a base station transmits to a terminal a generated indication signaling, and the terminal determines, on the basis of the received indication signaling, the time domain initial positions of the downlink data channel in L downlink TTIs. With the method, when the downlink control channel only appears in a part of the positions in a frequency domain or does not appear at all, and when the downlink control channel does not occupy the complete downlink control area in the time domain or the resources occupied by the downlink control channel in the time domain are variable, the base station can still accurately notify the terminal the time domain initial positions of the downlink data channel.
