S701：Communication equipment A sends resources mode configuration information to communication equipment B.

Wherein, the resources mode configuration information includes the positional information of self-interference channel estimating resource and quiet The positional information of silent resource.Wherein, self-interference channel estimating resource is used for communication equipment A on the resource Carry out self-interference channel estimation, and silent resource to estimate for the self-interference channel that communication equipment B carries out opposite end Meter.Specifically, the distribution density of the distribution density and silent resource of self-interference channel estimating resource can be with root Flexibly arranged according to demand.Self-interference channel estimating resource, is distributed closeer, self-interference channel on frequency domain The accuracy of estimation is higher, is distributed closeer in time domain, and its dynamic tracking is higher, identical principle, quiet Silent resource, is distributed closeer on frequency domain, the accuracy that the self-interference channel of communication equipment B is estimated is higher, when It is distributed closeer on domain, the dynamic tracking of communication equipment B is higher.If however, both resource distribution In intensive, then can cause volume of transmitted data step-down, accordingly, it would be desirable to rationally be arranged with reference to practical situation. The present embodiment is chosen several resource distribution examples and is illustrated.

Figure 11 is the schematic diagram of self-interference removing method resource distribution embodiment of the present invention, and Figure 12 is this The schematic diagram of invention self-interference removing method resource distribution embodiment two, Figure 13 are eliminated for self-interference of the present invention The schematic diagram of method resource distribution embodiment three, Figure 11 to Figure 13 show self-interference channel estimating resource With the different distribution situation of silent resource, in figure a minimum grid represents a minimum running time-frequency resource Block, as illustrated, with the self-interference channel estimating resource same position of communication equipment A at communication equipment The running time-frequency resource of B is the communication equipment at silent resource, with the silent resource same position of communication equipment A The running time-frequency resource of B is self-interference channel estimating resource.Figure 11 to Figure 13 is given with minimum running time-frequency resource Resource distribution of the block for unit, this is the resource distribution for more refining.
