Description
Technical field
The present invention relates to mobile communication technology, particularly interference control method and device.
Background technology
At present, mainly in Long Term Evolution (LTE) system adopt following two kinds of networking modes: frequency duplex factor as one is that networking mode and the frequency duplex factor as one of N is 1 networking mode, and N is the positive integer greater than 1.
In first kind of networking mode, total available bandwidth of system is divided into N subband, and pairwise orthogonal, N different sub-district takies N different subband respectively.
Fig. 1 is the networking mode sketch map of N for existing frequency duplex factor as one.As shown in Figure 1; Suppose that total available bandwidth is 60MHz, it is divided into 3 subbands (value that is N is 3), each subband is 20MHz (promptly the system bandwidth of 3 sub-districts is 20MHz); And pairwise orthogonal between 3 subbands, sub-district A, sub-district B and sub-district C take different subbands respectively.
In second kind of networking mode, total available bandwidth not to be divided, different sub-districts all takies total available bandwidth.
Fig. 2 is 1 networking mode sketch map for existing frequency duplex factor as one.As shown in Figure 2, suppose that total available bandwidth is 20MHz, sub-district A, sub-district B and sub-district C all take the bandwidth of this 20MHz.
For first kind of networking mode, because the subband pairwise orthogonal that each sub-district takies, so the interference of minizone is less, but the bandwidth availability ratio under this networking mode is lower.For second kind of networking mode, though can improve bandwidth availability ratio, the interference of minizone is bigger, particularly disturbs particularly serious for edge customer.
To the problems referred to above, other a kind of networking mode has been proposed, i.e. the networking mode of frequency shift channeling in the prior art again.
In this networking mode, total available bandwidth is divided into N subband, N is the positive integer greater than 1, pairwise orthogonal or have lap between N the subband, and have at least between two subbands and have lap; To each subband; Calculate the correlation between itself and other subband respectively, the correlation of being mentioned here is meant that two laps between the subband account for the ratio of the bandwidth sum of two subbands; Lap between two subbands is many more, and the correlation between them is big more; The allocation of subbands that correlation is less is given adjacent sub-district, and the allocation of subbands that correlation is bigger is given the sub-district far away that is separated by.
Fig. 3 is the networking mode sketch map of existing frequency shift channeling.As shown in Figure 3, suppose that total available bandwidth is 22.16MHz, it is divided into 3 subbands (value that is N is 3), each subband is 20MHz, and all has lap between any two, and sub-district A, sub-district B and sub-district C take different subbands respectively.
Can find out that than two kinds of networking modes before, this networking mode has taken into full account interference and these two factors of bandwidth availability ratio of minizone, neither can cause the interference of minizone excessive, also can not cause bandwidth availability ratio low excessively.But also can there be certain problem in this mode in practical application.
Fig. 4 is the down channel sketch map of each sub-district under the networking mode shown in Figure 3.As shown in Figure 4; Broadcast channel (PBCH) takies the middle 1.08MHz frequency band (oblique line filling part) of system bandwidth of each sub-district; Physical Downlink Shared Channel (PDSCH) takies all the other frequency bands (not filling part), and perhaps, synchronizing channel (SS) takies this 1.08MHz frequency band; The PDSCH channel still takies all the other frequency bands, and broadcast channel sends in different subframes with synchronizing channel usually; Can find out that the frequency band pairwise orthogonal that the broadcast channel of 3 sub-districts and synchronizing channel take is for synchronizing channel and the broadcast channel of any one sub-district such as sub-district A; When the load of sub-district C is light; Its PDSCH channel seldom sends, and the interference meeting of the minizone that receives of the broadcast channel of sub-district A and synchronizing channel is very little so, still; If the load of sub-district C is heavier; Its PDSCH channel continues to send, and then can cause serious disturbance to broadcast channel and the synchronizing channel of sub-district A, thereby influence the performance of broadcast channel and synchronizing channel.
