After the target adjacent area receives Load Information information, the HII bitmap that the HII bitmap-converted of eNB is become the target adjacent area according to frequency and the bandwidth information of target adjacent area and service eNB, and then determine to be subject to the RB that eNB disturbs, thereby avoid using the RB that is interfered as far as possible.
The embodiment of the invention provides three groups of concrete data to determine the concrete implementation of method so that the high interference indication information to be described.
First group of data: suppose service eNB residential quarter F
DL_low=2110MHz, N
Offs-DL=0MHz, N
DL=0MHz, system bandwidth BW
Channel=5MHz, the effectively shared bandwidth BW of RB
RB=0.18*25=4.5MHz; Adjacent area F
DL_low=2110MHz, N
Offs-DL=4150MHz, N
DL=4170.7MHz, system bandwidth BW
Channel=10MHz, the effectively shared bandwidth BW of RB
RB=0.18*50=9MHz.
Service eNB begins to travel through the adjacent area, obtains self and adjacent area RB carrier frequency and bandwidth information, judges whether self and adjacent area have overlapping frequency spectrum.With above parameter difference substitution formula one, calculate the carrier frequency F of service eNB
DLBe 2110MHz, wherein, the initial frequency of first RB of service eNB is F
DL-BW
RB/ 2=2107.75MHz; The carrier frequency of the adjacent area that calculates is 2112.07MHz, and wherein, the initial frequency of first RB is F
DL-BW
RB/ 2=2107.57MHz; The initial frequency of second RB is F
DL-BW
RB/ 2+0.18=2107.75MHz; By result of calculation as seen, the 2nd RB of first RB of service eNB and adjacent area begins fully overlapping, and namely the RB index difference is 1, as shown in Figure 3.
Service eNB judges whether there is high interference the adjacent area on overlapping frequency spectrum.Service eNB produces the HII bitmap of 25 RB according to the loading condition of local area, and as shown in Figure 4, the upper HII value of front 6 RB of service eNB residential quarter is 1.The the 2nd to 25 RB of service eNB and the spectrum overlapping of adjacent area RB, in the RB of these spectrum overlappings, the HII value on the 1st to the 6th RB is 1, therefore, the 2nd to the 6th RB of service eNB can produce high interference to the adjacent area.To have the adjacent area that produces high interference on overlapping frequency spectrum and the overlapping frequency spectrum and be set to the target adjacent area.
Travel through all residential quarters, find all target adjacent areas, and the HII bitmap of all target adjacent areas and service eNB is generated HII information add among the Load Information and send.
The adjacent area receives Load Information and high interference RB is dodged.After the adjacent area receives Load Information, obtain carrier frequency and the bandwidth information of described service eNB, and to calculate the RB index difference according to the carrier frequency of service eNB and bandwidth information be+1.The adjacent area is with the biasing of the 1st to 6 the RB index system one-plus-one individual 1 of HII=1, and 2-7 RB produces high interference in the adjacent area namely to draw service eNB.Service eNB will produce high interference on 2-7 the RB in adjacent area, then the adjacent area is avoided using 2-7 RB as far as possible, thereby avoid the generation of disturbing.
Second group of data supposed service eNB residential quarter F
DL_low=2110MHz, N
Offs-DL=0MHz, N
DL=0MHz, system bandwidth BW
Channel=5MHz, the effectively shared bandwidth BW of RB
RB=0.18*25=4.5MHz; Adjacent area F
DL_low=2110MHz, N
Offs-DL=4150MHz, N
DL=4170.7MHz, system bandwidth BW
Channel=5MHz, the effectively shared bandwidth BW of RB
RB=0.18*25=4.5MHz.
Service eNB begins to travel through the adjacent area, obtains self and adjacent area RB carrier frequency and bandwidth information, judges whether self and adjacent area have overlapping frequency spectrum.With above parameter difference substitution formula one, calculate the carrier frequency F of service eNB
DLBe 2110MHz, wherein, the initial frequency of first RB of service eNB is F
DL-BW
RB/ 2=2107.75MHz.
The carrier frequency of the adjacent area that calculates according to formula one is 2113.78MHz, and wherein, the initial frequency of first RB is F
DL-BW
RB/ 2=2111.53MHz; The difference of the initial frequency of the initial frequency of first RB of adjacent area and first RB of eNB obtains RB index difference, i.e. (2111.53-2107.75)/0.18=21 divided by the shared bandwidth of RB.So the RB index of service eNB and the RB index difference of adjacent area are-21, the 22nd RB of service eNB and first RB of adjacent area are fully overlapping, and namely front four RB of rear four RB of service eNB and adjacent area are overlapping, as shown in Figure 5.
Service eNB judges whether there is high interference the adjacent area on overlapping frequency spectrum.Service eNB produces the HII bitmap of 25 RB according to the loading condition of local area, as shown in Figure 5, and the upper HII=1 of the 1st, 2,4,5,6,9 RB of service eNB residential quarter.
Service eNB is got the rear sky that is that occurs simultaneously with the RB set of lap and the RB set of HII=1, although service eNB and adjacent area are described overlapping frequency spectrum is arranged, but service eNB does not produce high interference on overlapping frequency spectrum, therefore service eNB can not produce high interference to the adjacent area, described adjacent area is not the target adjacent area, and service eNB does not need the information to this adjacent area transmission HII yet.
The 3rd group of data suppose that service eNB residential quarter and adjacent area carrier frequency determined by 1 and 4 of E-UTRA (Evolved Universal Terrestrial Radio Access, the UMTS land face radio access of evolution) operational frequency bands respectively, and N
DLBe respectively 0 and 2399.Bandwidth is respectively 5MHz and 10MHz.
According to formula one, calculate service eNB and the adjacent area carrier frequency is respectively 2110MHz and 2154.9MHz.Service eNB is according to frequency and its working band of bandwidth calculation and the adjacent area zero lap of adjacent area, and described adjacent area is not the target adjacent area, and described service eNB does not need the information to this adjacent area transmission HII.
