Fig. 3 is the schematic flow sheet of N carrier frequency on-channel network method in the embodiment of the invention one.Referring to Fig. 3, this method may further comprise the steps:
Step 301: utilize the sky branch effect of smart antenna, each true sector is divided into three virtual sectors.
In the network that uses circle battle array smart antenna, the sub-district is equal to the sector.Suppose to represent a true cell in the wireless network with a circle or regular hexagon, when using circle battle array smart antenna in the network, the principle that the present invention divides virtual sectors is: utilize the sky branch effect of smart antenna, with the 360/N degree is subregion circumference angle, and each true cell evenly is divided into N virtual sectors.
According to mentioned above principle, the plot planning of present embodiment is: with 120 degree is subregion circumference angle, and each true cell evenly is divided into three virtual sectors.

Because the constraint of actual landform, the shape of sub-district may be irregular, and therefore, in actual applications, the subregion circumference angle of the shape of sub-district and virtual sectors correspondence can be made accommodation according to actual conditions.
Step 303: the DOA according to UE inserts corresponding virtual sectors with UE.
In this step, because NodeB has used smart antenna, therefore, when NodeB receives the signal that comes from UE in this sub-district, can make estimation to the DOA of UE, and virtually this UE is included into one of three virtual sectors according to resulting DOA, that is: when the DOA that detects certain UE as NodeB belongs to the scope of a certain virtual sectors that step 301 divides, just this UE is inserted or switch and go into this virtual sectors.
So far, finish N carrier frequency on-channel network method flow process in the embodiment of the invention one.
After carrying out plot planning according to embodiment one described method, the suffered co-channel interference situation analysis of UE and NodeB is as follows:
The suffered descending co-channel interference of UE shows as: in the neighbor cell of certain sub-district, UE place, with this UE under virtual sectors with the interference of the base station transmit signals of frequently virtual sectors to this UE, promptly in the neighbor cell with the interference of the base station transmit signals of virtual sectors frequently to UE in the virtual sectors of a certain frequency in this sub-district.Referring to Fig. 4, suppose that certain UE is in the virtual sectors 1, its adjacent same frequency virtual sectors is 2,3,4,5,6 and 7 these six virtual sectors.Wherein, the border of virtual sectors 2,3 and 4 base station distance virtual sectors 1 is nearer, but because the wave beam forming effect of smart antenna, virtual sectors 2,3 and 4 base station down wave beam main lobe can not point to the UE in the virtual sectors 1, so technical solution of the present invention can suppress base station transmit signals in virtual sectors 2,3 and 4 well to the interference of UE in the virtual sectors 1; Though and the base station down wave beam main lobe of virtual sectors 5,6 and 7 can point to the UE in the virtual sectors 1, but, since their base station from the beeline on the border of virtual sectors 1 all greater than 1.5 times of virtual sectors radius, so base station transmit signals also can access effective inhibition to the interference of UE in the virtual sectors 1 in virtual sectors 5,6 and 7.
The suffered up co-channel interference of NodeB shows as: in the neighbor cell of certain sub-district, NodeB place, with this NodeB under virtual sectors with the interference that transmits this NodeB base station is received of UE in the virtual sectors frequently, i.e. the interference that transmits base station in the virtual sectors of a certain frequency in this sub-district is received with the UE in the virtual sectors frequently in the neighbor cell.Referring to Fig. 4, be example with the NodeB in the virtual sectors 1, its adjacent same frequency virtual sectors is 2,3,4,5,6 and 7 these six virtual sectors.Wherein, the NodeB of virtual sectors 5,6 and 7 base station frontier distance virtual sectors 1 is nearer, but, because the DOA of the signal that UE is launched in these virtual sectors all drops on outside the DOA scope of virtual sectors 1 definition, both spatially have stronger resolvability, make the base station when carrying out the input processing, can eliminate co-channel interference well; And the beeline of the NodeB in the virtual sectors 1 of the UE in virtual sectors 2,3 and 4 is all greater than 1.5 times of virtual sectors radius, so the UE in virtual sectors 2,3 and 4 transmits, also can access effective inhibition to the interference of the up reception in base station in the virtual sectors 1.
As seen from the above-described embodiment, the present invention at first utilizes the sky branch effect of smart antenna, is subregion circumference angle with 120 degree, and each true cell evenly is divided into three virtual sectors; Then, dispose different carrier frequency, be the identical carrier frequency of virtual sectors configuration of same orientation in each true cell for three virtual sectors in the same true cell; At last, the DOA according to UE inserts corresponding virtual sectors with UE.So, can utilize on the one hand the beam shaping effect of smart antenna, make the main lobe direction difference of base station transmit signals in the nearer homogeneous frequency adjacent area of frontier distance, thereby effectively suppress the descending co-channel interference of homogeneous frequency adjacent area; On the other hand, DOA according to UE inserts corresponding virtual sectors with UE, make NodeB in the nearer homogeneous frequency adjacent area of frontier distance to differentiate and come from the upward signal of this sub-district UE, thereby effectively suppressed the descending co-channel interference of homogeneous frequency adjacent area according to the DOA of upward signal; This shows that the present invention can effectively reduce interference between common-frequency near regions.
Being example with circle battle array smart antenna in the above embodiments has been described in detail the embodiment of technical solution of the present invention, is introduced implement the present invention in the system that uses the linear array smart antenna below.
Embodiment two:
Present embodiment is implemented the present invention in the TD-SCDMA system of 3 carrier frequency of 5MHz bandwidth, in the system, the smart antenna that NodeB adopted is three fan linear array smart antennas.
Fig. 5 is the schematic flow sheet of N carrier frequency on-channel network method in the embodiment of the invention two.Referring to Fig. 5, this method may further comprise the steps:
Step 501: utilize the sky branch effect of smart antenna, each true sector is divided into N virtual sectors.
In the network that uses the linear array smart antenna, if represent the group number of employed smart antenna with x, then true cell is divided into x true sector by smart antenna, and true cell with the corresponding relation of true sector is: the corresponding true sector of a 360/x degree subregion of each true cell.Therefore, in the network that uses three fan linear array smart antennas, each true cell is subregion circumference angle by smart antenna with 120 degree, evenly is divided into three true sectors, and the reception and the emission of radiofrequency signal carried out in each true sector by a linear array smart antenna.
When using the linear array smart antenna in the network, the principle that the present invention divides virtual sectors is: each true sector is divided into N virtual sectors, make that the covering radial distance of the virtual sectors that mediates is distal to the virtual sectors that is in two side positions in each true sector.According to mentioned above principle, in the present embodiment, each true sector is divided into 3 virtual sectors.
Step 502: the virtual sectors that mediates in three true sectors for same true cell disposes different carrier frequency respectively, is that the virtual sectors that is in two side positions in three true sectors of same true cell disposes the carrier frequency of the virtual sectors in centre position in the true sector that is close to virtual sectors, also the virtual sectors for same orientation in each true cell disposes identical carrier frequency.
After dividing according to step 501 pair true sector, three true sectors in each true cell all are divided into three virtual sectors.In this step, the virtual sectors that mediates in three true sectors for same true cell disposes respectively after different carrier frequency, the carrier frequency for the virtual sectors in centre position in the true sector that virtual sectors disposes and this virtual sectors is close to that is in two side positions in three true sectors of same true cell, will form in the sub-district as shown in Figure 6 and divide.
Fig. 6 is that the virtual sectors in the true cell is divided schematic diagram in the embodiment of the invention two.Referring to Fig. 6, represent to dispose the virtual sectors of same carrier, represent to dispose the virtual sectors of different carrier frequency with the virtual sectors shown in the different gray scales with the virtual sectors shown in the same grayscale among the figure.Wherein, regular hexagon is represented a true cell, three mark off three true sectors in this sub-district by the outward extending straight line in regular hexagon center, the virtual sectors that mediates in three true sectors illustrates with different gray scales, three virtual sectors in the same true sector illustrate with different gray scales, and it is identical with the virtual sectors in centre position in the true sector of its next-door neighbour to be in the gray scale of the virtual sectors of two side positions in the true sector.For example, virtual sectors shown in the figure 1,1 ' and 1 " be three virtual sectors of being divided in the same true sector, illustrate with different gray scales; Virtual sectors 1,2 and 3 is respectively the virtual sectors that mediates in three true sectors, illustrates with different gray scales; With virtual sectors 2 ' and 3 " next-door neighbour true sector be virtual sectors 1,1 ' and 1 " true sector, place, and the virtual sectors that mediates in this true sector is a virtual sectors 1, therefore, virtual sectors 2 ' and 3 " gray scale identical with virtual sectors 1; similarly, virtual sectors 1 " with 3 ' gray scale and virtual sectors 2 identical, virtual sectors 1 ' and 2 " gray scale identical with virtual sectors 3.If three carrier frequency are designated as F respectively
1, F
2And F
3, then in this step, can dispose F respectively for virtual sectors 1,2 and 3
1, F
2And F
3, and be virtual sectors 2 ' and 3 " configuration F
1, be virtual sectors 1 " and 3 ' configuration F
2, be virtual sectors 1 ' and 2 " configuration F

Then, divide schematic diagram according to virtual sectors shown in Figure 6, the identical carrier frequency of virtual sectors configuration for same orientation in each true cell can obtain plot planning as shown in Figure 7.
Fig. 7 is the plot planning schematic diagram of virtual sectors in the embodiment of the invention two.Referring to Fig. 7, wherein, each regular hexagon is represented a true cell as shown in Figure 6, sees also the related description of Fig. 6 about the division of virtual sectors in a certain true cell, does not repeat them here.In Fig. 7, represent to dispose the virtual sectors of same carrier, represent to dispose the virtual sectors of different carrier frequency with the virtual sectors shown in the different gray scales with the virtual sectors shown in the same grayscale.For example, the carrier frequency that is disposed in the virtual sectors shown in the figure 1,2,3,4,5,6 and 7 is identical.
Because the constraint of actual landform, the shape of cell/section may be irregular, and therefore, in actual applications, the division of the shape of cell/section and corresponding virtual sector can be made accommodation according to actual conditions.
Step 503: the DOA according to UE inserts corresponding virtual sectors with UE.
In this step, similar with embodiment one step 303, when the DOA that detects certain UE as NodeB belongs to the scope of a certain virtual sectors that step 501 divides, just this UE is inserted or switch and go into this virtual sectors.
So far, finish N carrier frequency on-channel network method flow process in the embodiment of the invention two.
After carrying out plot planning according to embodiment two described methods, the suffered co-channel interference situation analysis of UE and NodeB is as follows:
The suffered descending co-channel interference of UE shows as: in the adjacent sectors of certain sector, UE place, with this UE under virtual sectors with the interference of the base station transmit signals of frequently virtual sectors to this UE.Referring to Fig. 7, suppose that certain UE is in the virtual sectors 1, its adjacent same frequency virtual sectors is 2,3,4,5,6 and 7 these six virtual sectors.Wherein, the border of virtual sectors 6 and 7 base station distance virtual sectors 1 is nearer, but because the wave beam forming effect of smart antenna, virtual sectors 6 and 7 base station down wave beam main lobe can not point to the UE in the virtual sectors 1, so technical solution of the present invention can suppress base station transmit signals in virtual sectors 6 and 7 well to the interference of UE in the virtual sectors 1; Though the base station down wave beam main lobe of virtual sectors 2 and 5 can point to the UE in the virtual sectors 1, but, because their base station is far away from the border of virtual sectors 1, so base station transmit signals also can access effective inhibition to the interference of UE in the virtual sectors 1 in virtual sectors 2 and 5; Virtual sectors 3 and 4 base station, far away apart from the border of virtual sectors 1 on the one hand, its base station down wave beam main lobe can not point to the UE in the virtual sectors 1 on the other hand, and therefore, base station transmit signals also can access effective inhibition to the interference of UE in the virtual sectors 1 in the virtual sectors 3 and 4.
The suffered up co-channel interference of NodeB shows as: in the adjacent sectors of certain sector, NodeB place, with this NodeB under virtual sectors with the interference that transmitting this NodeB base station is received of UE in the virtual sectors frequently.Referring to Fig. 7, be example with the NodeB in the virtual sectors 1, its adjacent same frequency virtual sectors is 2,3,4,5,6 and 7 these six virtual sectors.Wherein, the NodeB of virtual sectors 6 and 7 base station frontier distance virtual sectors 1 is nearer, but, because the DOA of the signal that UE is launched in these virtual sectors all drops on outside the DOA scope of virtual sectors 1 definition, both spatially have stronger resolvability, make the base station when carrying out the input processing, can eliminate co-channel interference well; UE in the virtual sectors 2 and 5 distance of NodeB in the virtual sectors 1 is far away, so the interference that the UE in virtual sectors 2 and 5 transmits to the up reception in base station in the virtual sectors 1 also can access effective inhibition; UE in the virtual sectors 3 and 4, far away apart from the border of virtual sectors 1 on the one hand, the DOA of the signal that its UE launched all drops on outside the DOA scope of virtual sectors 1 definition on the other hand, both spatially have stronger resolvability, therefore, the interference that transmits to the up reception in base station in the virtual sectors 1 of the UE in the virtual sectors 3 and 4 also can access effective inhibition.
As seen from the above-described embodiment, the present invention is in the system that uses the linear array smart antenna, at first, utilize the sky branch effect of smart antenna, each true sector is divided into three virtual sectors, then, the virtual sectors that mediates in three true sectors for same true cell disposes different carrier frequency respectively, dispose the carrier frequency of the virtual sectors in centre position in the true sector that is close to this virtual sectors for the virtual sectors that is in two side positions, and be the identical carrier frequency of virtual sectors configuration of same orientation in each true cell, at last, DOA according to UE inserts corresponding virtual sectors with UE, so, the up co-channel interference and the descending co-channel interference that have effectively suppressed homogeneous frequency adjacent area have reached the purpose of the co-channel interference between effective reduction neighbor cell.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.All any modifications of being done within the spirit and principles in the present invention, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
