[0285] A way of configuring parameters of the D2D resource area, the configuration parameters include:

[0286] The period of the D2D resource area, the frequency domain resource bandwidth of the D2D resource area, the offset of the wireless frame number (SFN) corresponding to the starting position of the D2D resource area, the number of D2D subframes in the D2D resource area, and the corresponding D2D subframes in the D2D resource area The radio frame position of the D2D resource area, the D2D subframe position in the D2D resource area, the user equipment determines the D2D resource area according to the configuration parameters; or,

[0319] For the discovery type corresponding to the second resource allocation method or the communication type corresponding to the first resource allocation method, in addition to configuring the D2D resource area parameters, it is also necessary to configure the parameters of the D2D user equipment dedicated resources, and the user equipment determines according to the dedicated resource parameters. The resource location dedicated to the user equipment is used to send a discovery signal corresponding to the second resource allocation manner or a communication signal corresponding to the first resource allocation manner.

[0320] The resource location dedicated to the D2D user equipment can be indicated by two parameters in the time domain and frequency domain. Taking the discovery resource as an example, for example: Td2d=0 means that the discovery subframe in the radio frame whose radio frame number SFN is odd in the discovery resource area is The time domain position of a d...

[0326] For the configuration of D2D resources between different adjacent cells, it may be necessary to indicate configuration signaling between the cells. The following uses the D2D discovery technology as an example to illustrate, but it is also applicable to the D2D communication technology.

[0327] For adjacent cells in a synchronous network, timing is synchronized between adjacent cells, and radio frames and radio frame numbers are aligned. Different cells adopt the same discovery resource configuration, so that the user equipment directly determines the discovery resource area of ​​the adjacent cell according to the discovery resource configuration information of the current cell, and receives the discovery signal of the adjacent cell in the discovery resource area.

[0328] For adjacent cells in an asynchronous network, timing between adjacent cells is not synchronized, and radio frames and radio frame numbers are not aligned. Even if different cells adopt the same dis...
