    Abstract: Disclosed are a method and an apparatus for transmitting D2D signals, wherein the method comprises: detecting a synchronization signal and/or a D2D signal, and determining a synchronization reference for sending or receiving other D2D signals based on the synchronization signal and/or the D2D signal; based on information carried in the detected synchronization signal and/or the D2D signal, determining a D2D resource configuration; and based on the determined synchronization reference for sending or receiving the other D2D signals and the determined D2D resource configuration, determining a resource position used for transmitting D2D signals, and sending or receiving the other D2D signals in the resource position. By enabling a UE to learn the D2D resource configuration based on the synchronization signal and/or the D2D signal, the present application prevents the UE from always using fixed resources when transmitting D2D signals, thus reducing mutual interference and improving transmission efficiency and quality.

    Abstract: Disclosed are methods and devices for transmitting and receiving data and system for receiving data. A method for transmitting data includes determining, by a transmitting device, a first transmission resource for data transmission, and determining a second transmission resource from a second transmission resource pool corresponding to the first transmission resource; and transmitting, by the transmitting device, to-be-transmitted data over the first transmission resource and the second transmission resource. The receiving device can receive data information over the first transmission resource and the second transmission resource associated with the first transmission resource, so it is able to ensure that the receiving device combines the signals transmitted from a UE at the transmitting device over a plurality of transmission resources and detects the combined signals, so as to improve the detection success rate, thereby to further improve the transmission performance.

    Abstract: The present invention relates to the field of communications, and disclosed are a method and device for determining a PDSCH transmission resource. The method is: in the embodiments of the present invention, a network side determines a mapping relationship between a PDSCH transmission point and a zero-power CSI-RS for UE, and the UE does not receive a PDSCH over a zero-power CSI-RS resource which corresponds to a cell currently transmitting the PDSCH and measures an interference and still receives the PDSCH over a zero-power CSI-RS resource which corresponds to a cell not currently transmitting the PDSCH and measures an interference, thereby ensuring that the UE can accurately measure the interference and further improving the accuracy of CQI estimation; furthermore, the signalling overhead required for realizing the technical solution of the present invention is very small, only some RRC signalings are required, and a dynamic signaling can reuse a current signaling to the greatest extent, in this way, the compatibility of the system is effectively improved and the complexity of implementation is reduced.
