Data transmission block transmitting and receiving method and device

The invention provides a data transmission block transmitting and receiving method and device, and the method comprises the steps: determining a first type of cells which support dispatching distribution signal transmission, and determining a second type of cells which only support data transmission; transmitting a first type of dispatching distribution signals and one of more dispatching distribution signals of the second type in the first type of cells, wherein the first type of dispatching distribution signals are used for indicating the transmission of the same data transmission block at a plurality of transmission time intervals contained in a preset time, and the second type of dispatching distribution signals which are transmitted at the preset transmission time intervals of the preset time are used for indicating the transmission of the data transmission block at the preset transmission time intervals; and transmitting the data transmission block in the second type of cells according to the first type of dispatching distribution signals, and transmitting the data transmission block in the first type of cells and/or the second type of cells according to the second type of dispatching distribution signals, thereby solving problems that the utilization rate of related technological resources is not high and the transmission efficiency of the data block is low, and improving the transmission efficiency of data and resource utilization rate.
