In the embodiment of the present invention, " multiple " refer to two or more."and/or" describes the incidence relation of affiliated partner, indicates may exist three kinds of relationships, for example, A and/or B, can indicate: individualism A exists simultaneously A and B, these three situations of individualism B.Character "/" typicallys represent the relationship that forward-backward correlation object is a kind of "or".
Two base stations adjacent for frequency point, the frequency spectrum adjustment of some base station, such as uplink spectrum is converted into downstream spectrum and carries out downlink data transmission, it is more likely that another base station can be interfered, to generate the interference between adjacent spectra.Such as, flexibly duplex (flexible duplex), the enhancing technologies such as interference management and service adaptation (enhanced interference management and traffic adaptation, eIMTA) may all introduce the interference between adjacent spectra.
Referring to FIG. 1, it is a kind of schematic diagram of flexible duplex provided in an embodiment of the present invention.As shown in Figure 1, usually upstream band is used for transmission upstream data, downstream bands are used for transmission downlink data, guard band can be set between upstream band and downstream bands.When downlink traffic is apparently higher than upstream traffic, uplink frequency spectrum resource is superfluous, and down frequency spectrum resources are insufficient, therefore part uplink frequency spectrum resource can be used to transmit downlink data, at this point, the partial frequency spectrum resource in upstream band is converted to down frequency spectrum resources, downlink data transmission is carried out.It is similar therewith that down frequency spectrum resources are converted into uplink frequency spectrum resource.This technology by uplink and downlink frequency spectrum resource flexible conversion is both flexible duplex technology.
Referring to FIG. 2, it is a kind of schematic diagram of a scenario of flexible duplex provided in an embodiment of the present invention, it is applied in frequency division duplex (frequency division duplex, FDD) communication system.As shown in Figure 2, adjacent base station 01 and base station 02, base station 01 is using fixed uplink spectrum and downstream spectrum, base station 02 is using flexibly duplex, i.e. frequency spectrum can the flexible conversion between uplink spectrum and downstream spectrum according to actual needs, such as in some cases, downstream spectrum is not enough, uplink spectrum is available free, so that it may which part sub-frame of uplink is converted to downlink subframe.As shown in Figure 1, in the uplink spectrum of base station 02, there are 4 sub-frame of uplink to be used as downlink subframe, the power of downlink transfer is larger, downlink subframe after so this 4 conversions may interfere 4 sub-frame of uplink corresponding in 01 uplink spectrum of base station, and as shown in the figure, solid line represents useful signal, dotted line represents interference, and the uplink (solid line expression) of terminal 03 will receive the interference of the downlink transfer (dotted line expression) of base station 02.
