    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: Methods and apparatuses for transmitting coding indication information and determining a precoding matrix, for use in resolving the problem that the resolution of code words in a codebook generated by using a combination of a beam vector subgroup and column selection cannot be flexibly adjusted. The method comprises: determining first precoding indication information and second precoding indication information, the first precoding indication information corresponding to a first-stage precoding matrix, the second precoding indication information corresponding to a direction weighting vector and a phase adjustment factor, the direction weighting vector being used for performing interpolation processing on parts representing angles corresponding to beam vectors in the all beam vectors in each polarization direction in the first-stage precoding matrix, the phase adjusting factor being used for performing phase adjustment on different polarization directions of the first-stage precoding matrix, and the first-stage precoding matrix, the direction weighting vector, and the phase adjustment factor being used for generating a precoding matrix. The resolution of a precoding matrix is flexibly adjusted by using a direction weighting vector.

    Abstract: Embodiments of the present application relate to the technical field of wireless communication, in particular a D2D switchover method, system, and device, for solving the problem in prior art of the lack of mechanism for D2D switchover for D2D user devices under appropriate conditions so as to ensure the short-distance transmission quality in the situation where an LTE system has too high a load and interference is too strong. Embodiments of the present invention comprise: a network device determines, according to resource management information and/or channel status information whether a D2D user device needs to perform a D2D switchover; when the D2D user device is determined to need to perform a D2D switchover, the D2D user device is triggered to switch to a heterogeneous system and conduct end-to-end communication, or to conduct end-to-end communication via the network device, or to conduct in the current system end-to-end communication not controlled by the network device. The method in the embodiments of the present invention ensures that D2D devices can perform D2D switchover under appropriate conditions even when an LED system has too high a load and interference is too strong, thereby enhancing the end-to-end communication performance.
