Abstract: Embodiments of the present invention propose a D2D communications method, apparatus, and system. In the solution, a D2D SPS available period in which a first terminal is capable of using a D2D SPS resource is greater than one SC period. Therefore, in the D2D SPS available period, the first terminal needs to determine the D2D SPS resource only one time, and a second terminal also needs to decode SCI only one time to determine the D2D SPS resource. In this way, the first terminal does not need to determine a D2D SPS resource in each SC period, and the second terminal also does not need to decode SCI in each SC period to determine the D2D SPS resource. Therefore, D2D communication efficiency is improved.

Abstract: The present invention relates to the field of communications technologies, and discloses methods for transmitting and storing downlink data, a base station, and a terminal. In this solution, each time when a base station transmits downlink data, bits are selected in such a way that a length and a start point of a sequence that a terminal of any terminal category expects to receive in initial transmission (or retransmission) of a code block are the same as a length and a start point of a sequence that a transmit end determines to transmit for the same code block, so that the terminal can perform reliable decoding. Therefore, a disadvantage is avoided that the terminal cannot correctly perform storing and further cannot correctly perform decoding each time when the terminal stores a retransmitted code block for a same code block, and decoding accuracy of the terminal is improved.
