Abstract: The present invention relates to the technical field of communications, and specifically relates to a method and device for determining the initial positions of a downlink data channel. The present invention solves the problem of determining the initial positions in the time domain of a downlink data channel when the resources occupied by a downlink control channel in the time domain are variable. The method comprises: 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 said 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, so that the terminal can accurately receive downlink data, thereby enhancing the efficiency and reliability of the terminal reception of downlink data, and further enhancing the spectrum efficiency as well as the user experience.

Abstract: The present disclosure discloses a method and a device for communication. The method includes: determining, by the user equipment, a specific uplink-downlink sub-frame configuration when the uplink-downlink sub-frame configuration information is not received by the user equipment during the period; and communicating with a network side equipment by the user equipment during the period based on the specific uplink-downlink sub-frame configuration. By the solution of the present disclosure, a probability of the situation that the user equipment cannot communicate with the network normally as the user equipment does not correctly receive the physical layer control signaling which carries the uplink-downlink sub-frame configuration information and is sent from the network side is reduced, and user throughput is improved.
