摘要： Disclosed are a method for determining and indicating a transmission resource, and a terminal and a base station. The method comprises: a base station and a UE agreeing that at least one subframe of a set number of wireless frames is used as a reference subframe, and considering that all REs in the reference subframe which are probably occupied by a ZP/NZP CSI-RS are REs unable to be used for EPDCCH transmission; and the base station sending to a UE configuration information about REs in other subframes which are occupied by the ZP/NZP CSI-RS in the reference subframe, so that the UE can determine REs in other subframes, which are probably occupied by the ZP/NZP CSI-RS but are in fact not occupied by the ZP/NZP CSI-RS as REs used for the EPDCCH transmission, thereby increasing the number of REs used for EPDCCH transmission, and reducing the system overheads.

摘要： Disclosed are a D2D data transmission method and device. The method comprises: determining, by a D2D data sending end, a state of each sending opportunity in a sending window in the same manner as a D2D data receiving end, wherein the sending window is uniformly divided into a plurality of sending opportunities, and the state of each sending opportunity comprises a data sending state and a silent state; and sending D2D data to the D2D data receiving end in the sending opportunity of each data sending state in the sending window. By means of the technical solution provided in the embodiments of the present application, a D2D data sending end sends data on different resources (sending opportunities) or becomes silent, so that different D2D data sending ends are staggered on the resources, thereby alleviating the influence of “near-far” effects.

摘要： Disclosed are a power control method and device for D2D transmission. The method includes determining an upper limit value of interference power corresponding to a terminal. The upper limit value of the interference power is the maximum interference value which is allowed by a base station and generated by D2D transmission to cellular transmission. The base station sending the upper limit value of the interference power to the terminal the terminal determines the upper limit value of D2D transmission power by using the upper limit value of the interference power. The terminal determines the upper limit value of the D2D transmission power, and determines the D2D transmission power, the D2D transmission power of the terminal device can be controlled, transmitting power of the D2D transmission is controlled to make the interference generated by same to the cellular transmission to a controlled range, and the interference of a D2D signal to a cellular signal is controlled.
