Embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer; To combine the accompanying drawing in the embodiment of the invention below; Technical scheme in the embodiment of the invention is carried out clear, intactly description; Obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
In one embodiment of the invention, utilizing cell edge frequency band is fixed, and (Resource Block, RB) number is also fixing thereupon for the Resource Block of the available edge band of sub-district.When sub-district or adjacent area edge band load variations, can not adjust available edge band RB number adaptively, can cause band resource waste and resource fragmentation.In addition, under the mode of this built-in edge frequency band, when the light and adjacent area edge band load of this utilizing cell edge frequency band load increases; It is lower this sub-district RB utilance to occur; And the adjacent area edge customer is dispatched at center frequency-band, and the edge customer that the adjacent area so just possibly occur uses identical frequency resource, Inter-Cell Interference Coordination (Inter-Cell Interference Coordination with this Cell Edge User; ICIC) effect reduces greatly, and the performance of edge customer also can worsen.
Fig. 1 is the method flow sketch map of first embodiment of the invention, comprising:
Step 11: the base station is the corresponding initial edge frequency bands of a plurality of cell allocation, the initial edge frequency band non-overlapping copies of adjacent sub-district correspondence in said a plurality of sub-districts.
Generally, a base station subordinate's sub-district number is three, in order to reduce the interference between each sub-district, need be the different initial edge frequency band of these three cell allocation.Fig. 2 is an initial edge bandwidth assignment sketch map in the one embodiment of the invention, referring to Fig. 2, is one group with 3 sub-districts, and it is example that the initial edge frequency band of the interior sub-district of group needs non-overlapping copies.
Above-mentioned sub-district can specifically comprise the sub-district of different mode, and for example, in Fig. 2, from top to bottom, three sub-districts are respectively pattern 1 sub-district, and pattern 2 sub-districts and mode 3 sub-district in each mode cell, need allocations of edge frequency band and center frequency-band.Wherein, the RB of the lowest frequency end of each edge band is the edge band starting point; Partial-band at least in the frequency band except that the edge frequency band is a center frequency-band.In addition; The corresponding initial edge frequency band of each mode cell normally ICIC effect frequency band 1/3; The RB number that ICIC effect frequency band takies is that the RB number of cell system bandwidth occupancy deducts Physical Uplink Control Channel (Physical Uplink Control Channel, the maximum RB number that PUCCH) takies.
Suppose that the RB that ICIC effect frequency band takies is RB1～RB18, each mode cell takies 1/3 of ICIC effect frequency band respectively, and then the edge band that takies of pattern 1 sub-district is RB1～RB6, and the center frequency-band that takies is RB7～RB18; The edge band that pattern 2 sub-districts take is RB7～RB12, and the center frequency-band that takies is RB1～RB6 and RB13～RB18, and the edge band that the mode 3 sub-district takies is RB13～RB18, and the center frequency-band that takies is RB1～RB12.As can beappreciated from fig. 2, the corresponding initial edge frequency band in the sub-district of different mode is a non-overlapping copies.
Step 12: if the required edge band in a sub-district in said a plurality of sub-district surpasses corresponding initial edge frequency band; Then obtain the situation that takies of RB resource of initial edge frequency band of the adjacent area of a said sub-district; And, take the idle RB resource of the initial edge frequency band of said adjacent area according to the situation that takies and the said edge band that the sub-district is required of the RB resource of the initial edge frequency band of said adjacent area.
For example; When if the edge customer of pattern 1 sub-district increases; Its required edge band increases; Possibly surpass corresponding initial edge frequency band, the edge band that then this moment, pattern 1 sub-district took possibly expanded on the initial edge frequency band of pattern 2 sub-districts or mode 3 cell initial edge band direction, takies the idle RB resource of the initial edge frequency band of adjacent mode cell.
Specific as follows; Suppose that the initial edge frequency band that pattern 1 sub-district takies is RB1～RB6; The initial edge frequency band that pattern 2 sub-districts take is RB7～RB12; The initial edge frequency band that the mode 3 sub-district takies is RB13～RB18, wherein the starting point of filling part (RB1, RB7, RB13) expression edge band.In the practical application scene, pattern 1 and pattern 2 sub-districts begin to take the RB in the initial edge frequency band of each pattern from the starting point of edge band.For example, the required edge band in pattern 1 sub-district need take 1 RB, and then RB1 is occupied; The required edge band in pattern 1 sub-district need take 3 RB, and then RB1-RB3 is occupied; By that analogy, the pattern 1 sub-district edge band scope that can take is RB1～RB6.The situation of pattern 2 sub-districts can be by that analogy.And mode 3 is the RB that preferentially takies the HFS in the initial edge frequency band, and for example, the required edge band in mode 3 sub-district need take 1 RB, and then RB18 is occupied; The required edge band in mode 3 sub-district need take 3 RB, and then RB16-RB18 is occupied; By that analogy, until the starting point of edge band, promptly the mode 3 sub-district edge band scope that can take is RB13～RB18.
If when the user increased on the edge of in pattern 1 sub-district, required edge band need take 8 RB, promptly surpass 6 RB of its original allocation, then need on the direction of module 2 sub-districts or mode 3 sub-district, expand, take the RB in the corresponding initial edge frequency band in adjacent area.With expansion on the direction of mode 3 sub-district is example, and then the edge band after the expansion of pattern 1 sub-district comprises the Initial R B1～RB6 of self, also comprises RB13 and RB14.Implement in the scene at this kind, the RB15 of the lowest frequency end of the edge band of mode 3 sub-district becomes the edge band starting point, and the edge band starting point integral body that is equivalent to the mode 3 sub-district moves two RB to front end.
Wherein, when the edge band that obtains the adjacent area takies situation, can adopt high interference indication (High Interference Indication; HII) message; For example, adopt the edge band of HII message learn mode 3 sub-districts that the free time is arranged, then expand to mode 3 sub-district direction.
In one embodiment of the invention, the idle RB (the idle RB of mode 3 sub-district) that the starting point of the edge band of the preferential acquisition frequency distance mode in pattern 1 sub-district 1 sub-district is far away.When these distances far away can occupied RB occupied after, in the time of still need taking more RB, then begin the nearer relatively RB (the idle RB of pattern 2 sub-districts) of starting point of the edge band of acquisition frequency distance mode 1 sub-district.Such scheduling resource mode has interference coordination effect between better cell.
Step 13: the base station will take the RB resource of the edge band of a said sub-district that obtains after the said idle RB resource, distribute to the edge customer of a said sub-district.
In the various embodiments of the present invention alleged user refer to can for the user in the communication system as mobile device use subscriber equipment.
Wherein, as shown in Figure 2, when being each mode cell allocated frequency band, comprise edge band and center frequency-band, wherein, edge band is distributed to edge customer and is used, and center frequency-band is distributed to central user and is used.Edge customer and central user can (Reference Signal Received Power, RSRP) value and adjacent area RSRP value be judged according to Serving cell pilot signal received power.For example, if the RSRP value of the RSRP value of pattern 1 sub-district that a certain user of pattern 1 sub-district service measures and pattern 2 sub-districts that measure or mode 3 sub-district less than the value of setting, then this user is an edge customer, otherwise is central user.
Determine user-center user or the edge customer of self service when certain mode cell after, then can center frequency-band RB resource be distributed to central user successively, edge band RB resource is distributed to edge customer successively.Expansion is an example to the mode 3 sub-district with above-mentioned pattern 1 sub-district, and RB1～RB6 that pattern 1 sub-district will be occupied and RB13 and RB14 distribute to the edge customer of pattern 1 sub-district service successively.
In addition, above-mentioned pattern 1 sub-district and pattern 2 sub-districts can be on from the low frequency to the high frequency direction, to distribute, and the mode 3 sub-district can be according to distributing to the low frequency direction from high frequency.For example, be example with the initial edge frequency band that distributes each mode cell, then pattern 1 sub-district priority allocation RB1 distributes RB6 at last, and pattern 2 sub-district priority allocation RB7 distribute RB12 at last, and the mode 3 sub-district is priority allocation RB18 then, distributes RB13 at last.
When present embodiment surpasses the initial edge frequency band of this sub-district through the required edge band of a certain mode cell; Take the RB of the initial edge frequency band of adjacent area; Make the edge band of each sub-district dynamically to take mutually; The edge band of realizing the sub-district can adaptively change, and avoids problems such as the wasting of resources that the built-in edge frequency band causes or resource fragmentation, improves Cell Edge User throughput and RB resource utilization.If the initial edge frequency band of this sub-district is enough, then can not go initiatively to take the edge band resource of other sub-district.This edge band scope of distributing with initial fixation is the basis, dynamically takies the method for other subdistrict frequency band resource according to practical situations, can reduce the design complexities of scheduler.
The initial edge frequency band that takies with pattern 1 sub-district below is RB1～RB6, and the edge band that pattern 2 sub-districts take is RB7～RB12, and the edge band that the mode 3 sub-district takies is that RB13～RB18 is the dynamic assignment mode of example explanation edge band.
Fig. 3 is the schematic flow sheet of the pattern 1 utilizing cell edge frequency band method of salary distribution in the one embodiment of the invention, and Fig. 4 is the corresponding resource allocation structure sketch map of Fig. 3.
Among this embodiment, idle RB resource preferentially comes from the starting point idle RB far away of the initial edge frequency band of the said pattern of distance 1 sub-district.For example: the idle RB (the idle RB of mode 3 sub-district) that the starting point of the initial edge frequency band of preferential acquisition frequency distance mode 1 sub-district, pattern 1 sub-district is far away.When these distances far away can occupied RB occupied after, in the time of still need taking more RB, then begin the nearer relatively RB (the idle RB of pattern 2 sub-districts) of starting point of the initial edge frequency band of acquisition frequency distance mode 1 sub-district.
Among this embodiment, the situation that the adjacent area is taken by pattern 1 sub-district according to idle RB moves the starting point of the initial edge frequency band of this adjacent area to front end.For example: the idle RB that pattern 1 sub-district takies is during from the mode cell (mode cell 3 or mode cell 2) of front end, and the starting point of the initial edge frequency band of the mode cell of front end (mode cell 3 or mode cell 2) needs correspondingly to move to front end.
Referring to Fig. 3, the method for present embodiment comprises:
Step 31: the RB resource of the initial edge frequency band of allocation model 1 sub-district is given the edge customer of pattern 1 sub-district successively.
For example, give edge customer according to the order of RB1～RB6 with the RB resource allocation of the initial edge frequency band of pattern 1 sub-district.
Step 32: if the RB resource allocation of the initial edge frequency band of pattern 1 sub-district finishes, the RB that then obtains the edge band of adjacent area takies situation.
For example, if after RB1～RB6 assigns, also there is the edge customer that does not have the allocations of edge band resource in pattern 1 sub-district, and then the edge band of pattern 1 sub-district can take situation according to the RB of the edge band of adjacent area and expands.
For example, each sub-district is through the mutual HII message of X2 interface between the base station eNB, and the RB that carries each sub-district edge band separately in this HII message takies situation.For example, the mode 3 sub-district is through also idle two RB of its edge band that takies of HII message informing pattern 1 sub-district and since the mode 3 sub-district be from high frequency to the low frequency direction on Resources allocation, if idle two RB, two then idle RB are RB13 and RB14.Certainly, the idle RB number in adjacent area also can be through calculating.For example, the mode 3 sub-district is x through its RB that takies of HII message informing, and then pattern 1 sub-district can obtain the idle RB number in mode 3 sub-district through subtraction y-x, and wherein, y is the RB number of mode 3 cell initial edge band.Can know the RB number that the initial edge frequency band of adjacent area takies during the configuration of each cell initial.
Step 33:, then take RB idle in the initial edge frequency band of mode 3 sub-district, the edge band of pattern 1 sub-district after obtaining expanding if the initial edge frequency band of mode 3 sub-district has the free time.
For example, two idle RB of mode 3 sub-district are RB13 and RB14, and the required edge band in pattern 1 sub-district is equal to, or greater than 8 RB, and then the edge band of pattern 1 sub-district after the expansion comprises RB1～RB6 and RB13, RB14.Certainly, the required edge band in pattern 1 sub-district greater than 6 RB but less than 8 RB, be 7 RB like required edge band, then can only take among the idle RB in mode 3 sub-district, for example, preferential expansion takies RB13.
Step 34: if after taking RB idle in the mode 3 cell initial edge band, pattern 1 sub-district also needs the RB resource of edge band, then takies the RB of the edge band of pattern 2 sub-districts.
For example, the idle RB number of pattern 2 utilizing cell edge frequency bands is α, if the edge band RB number that this moment, pattern 1 sub-district still needed is δ, the edge band RB number that then needs contention mode 2 sub-districts be λ=min (a, δ).Send HII message through the X2 mouth and give the adjacent area; λ the RB resource that contention mode 2 sub-districts begin from the initial RB of edge band; The initial RB of the edge band of pattern 2 sub-districts is corresponding to move λ RB to front end, but the initial RB of edge band of pattern 2 sub-districts moves the edge band most significant end of pattern 2 sub-districts at most.
Specifically can be referring to Fig. 4, if after pattern 1 sub-district takies 2 idle RB of mode 3 sub-district, also need 2 RB; If the idle RB number in pattern 2 sub-districts is equal to, or greater than 2 RB, then take pattern 2 sub-districts from 2 RB that low frequency begins, promptly take RB7 and RB8; At this moment; Because RB7, RB8 are taken by pattern 1 sub-district, then the edge band of pattern 2 sub-districts moves on needing, and promptly need give the edge customer of pattern 2 sub-districts from the RB that RB9 begins the edge band of allocation model 2 sub-districts.
Certainly, if the edge customer of pattern 2 or mode 3 sub-district increases, in the time of need taking more edge band resource, then preferentially take the RB that is taken by pattern 1 sub-district, the edge band resource that pattern 1 sub-district needs rollback to take at this moment.For example, the mode 3 sub-district also need take a RB, and then RB14 also continues to be taken by the mode 3 sub-district, and is no longer taken by pattern 1 sub-district.
In the present embodiment foregoing be with pattern 1 sub-district preferentially on the direction of mode 3 sub-district expansion be example, certainly, pattern 1 sub-district also can preferentially be expanded on pattern 2 sub-district modes.Specific as follows:
When pattern 1 sub-district need be expanded; If pattern 2 edge band RB have the free time, suppose that the idle RB number in pattern 2 sub-districts is d, if the edge band RB number that this moment, pattern 1 sub-district still needed is δ; The edge band RB number that then needs contention mode 2 sub-districts be λ=min (d, δ).Send HII message through the X2 mouth and give the adjacent area; λ the RB resource that contention mode 2 sub-districts begin from the initial RB of edge band; The initial RB of edge band of pattern 2 sub-districts moves λ RB to front end, but the initial RB of edge band of pattern 2 sub-districts moves the edge band most significant end of pattern 2 sub-districts at most.If still can not satisfy the demands, then expand to the idle RB resource of mode 3.If do not have idle RB, then do not expand.When pattern 2 sub-districts or the increase of mode 3 cell edge load, then calculate the edge band RB number that needs, preferentially seize the edge band that is taken by pattern 1, the edge band of pattern 1 sub-district expansion carries out corresponding rollback.
Fig. 5 is the schematic flow sheet of the pattern 2 utilizing cell edge frequency band methods of salary distribution in the one embodiment of the invention, and Fig. 6 is the corresponding resource allocation structure sketch map of Fig. 5.
Among this embodiment, the situation that the adjacent area is taken by pattern 2 sub-districts according to idle RB moves the starting point of the initial edge frequency band of this adjacent area to front end.For example: the idle RB that pattern 2 sub-districts take is during from the mode cell 3 of front end, and the starting point of the initial edge frequency band of the mode cell 3 of front end needs correspondingly to move to front end.
Referring to Fig. 5, the method for present embodiment comprises:
Step 51: the RB resource of the initial edge frequency band of allocation model 2 sub-districts is given the edge customer of pattern 2 sub-districts successively.
For example, give edge customer according to the order of RB7～RB12 with the initial edge bandwidth assignment with reference to Fig. 2.
Step 52: if the RB resource allocation of the initial edge frequency band of pattern 2 sub-districts finishes, the RB that then obtains the edge band of adjacent area takies situation.
For example, if after RB7～RB12 assigns, also there is the edge customer that does not have the RB of allocations of edge frequency band resource in pattern 2 sub-districts, and then the edge band of pattern 2 sub-districts can take situation according to the RB of the edge band of adjacent area and expands.
For example, each sub-district is through the mutual HII message of X2 interface, and the RB that carries edge band separately in this HII message takies situation.For example, pattern 1 sub-district is through also idle two RB of its edge band that takies of HII message informing pattern 2 sub-districts and since pattern 1 sub-district be from the low frequency to the high frequency direction on Resources allocation, if idle two RB, two then idle RB are RB5 and RB6.
Step 53:, then take RB resource idle in the initial edge frequency band of pattern 1 sub-district, the edge band of pattern 2 sub-districts after obtaining expanding if the RB resource of the initial edge frequency band of pattern 1 sub-district has the free time.
For example, two idle RB of pattern 1 sub-district are RB5 and RB6, and the required edge band in pattern 2 sub-districts is equal to, or greater than 8 RB, and then the edge band of pattern 2 sub-districts after the expansion comprises RB7～RB12 and RB5, RB6.Certainly, the required edge band in pattern 2 sub-districts greater than 6 RB but less than 8 RB, be 7 RB like required edge band, then can only take among the idle RB in pattern 1 sub-district, for example, preferential expansion takies RB6.
Step 54: if after taking RB resource idle in the pattern 1 cell initial edge band, pattern 2 sub-districts also need the RB resource of edge band, then take the RB resource of the edge band of mode 3 sub-district.
For example, the idle RB number of mode 3 utilizing cell edge frequency band does, if the edge band RB number that this moment, pattern 2 sub-districts still needed is δ, the edge band RB number that then needs contention mode 3 sub-districts be λ=min (b, δ).Send HII message through the X2 mouth and give the adjacent area; λ the RB resource that contention mode 3 sub-districts begin from the initial RB of edge band; The initial RB of the edge band of mode 3 sub-district moves λ RB to front end, but the initial RB of the edge band of mode 3 sub-district moves the edge band most significant end of mode 3 sub-district at most.
Specific as follows, if after pattern 2 sub-districts take 2 idle RB of pattern 1 sub-district, also need 2 RB.If the idle RB number in mode 3 sub-district is equal to, or greater than 2 RB, then take the mode 3 sub-district from 2 RB that low frequency begins, promptly take RB13 and RB14.At this moment, owing to RB13, RB14 are taken by pattern 2 sub-districts, then the start edge frequency band of mode 3 sub-district moves on needing, and promptly the edge band of mode 3 sub-district is assigned to RB15 at most.
Certainly, if the edge customer of pattern 1 or mode 3 sub-district increases, in the time of need taking more edge band resource, then preferentially take the RB that is taken by pattern 2 sub-districts, the edge band resource that pattern 2 sub-districts need rollback to take at this moment.For example, pattern 1 sub-district also need take a RB, and then RB5 also continues to be taken by pattern 1 sub-district, and is no longer taken by pattern 2 sub-districts.
In the present embodiment foregoing be with pattern 2 sub-districts preferentially on pattern 1 sub-district direction expansion be example, certainly, pattern 2 sub-districts also can preferentially be expanded on the mode of mode 3 sub-district.Specific as follows:
When pattern 2 utilizing cell edge frequency band loads increased, the RB resource of distributing to edge customer was according to distributing to front end from low frequency end.Still can not satisfy the demands after this cell initial edge band takes, then the edge band RB through HII message obtaining mode 3 sub-districts takies situation.If the edge band RB of mode 3 sub-district has the free time, the idle RB of edge band that then calculates mode 3 counts e.If the edge band RB number that this moment, pattern 1 sub-district still needed is δ, the edge band RB number that then needs contention mode 2 sub-districts be λ=min (e, δ).Send HII message through the X2 mouth and give adjacent area, λ the RB that contention mode 3 sub-districts begin from the initial RB of edge band.The initial RB of the edge band of mode 3 sub-district upwards moves λ RB, but the initial RB of the edge band of mode 3 moves the edge band most significant end of mode 3 sub-district at most.If can't satisfy the demands, then oppositely take the idle edge band of pattern 1 to the low frequency end expansion.If pattern 1 no idle RB then do not expand.When pattern 1 or the increase of mode 3 cell edge load, then calculate the edge band RB number that needs, preferentially seize the edge band that is taken by pattern 2, the edge band of pattern 2 sub-districts expansion carries out corresponding rollback.
Fig. 7 is the schematic flow sheet of the mode 3 utilizing cell edge frequency band method of salary distribution in the one embodiment of the invention, and Fig. 8 is the corresponding resource allocation structure sketch map of Fig. 7, and it is example that present embodiment is preferentially expanded on pattern 2 sub-district directions with the mode 3 sub-district.
Among this embodiment, idle RB resource preferentially comes from the nearer idle RB of starting point of the initial edge frequency band of the said mode 3 of distance sub-district.For example: the idle RB (the idle RB of pattern 2 sub-districts) that the starting point of the initial edge frequency band of preferential acquisition frequency distance mode 3 sub-districts, mode 3 sub-district is nearer.After these close together can occupied RB occupied, in the time of still need taking more RB, then begin the starting point RB (the idle RB of pattern 1 sub-district) far away relatively of the initial edge frequency band of acquisition frequency distance mode 3 sub-districts.
Referring to Fig. 7, the method for present embodiment comprises:
Step 71: the RB resource of the initial edge frequency band of allocation model 3 sub-districts is given the edge customer of mode 3 sub-district successively.
For example, give edge customer according to the order of RB18～RB13 with the initial edge bandwidth assignment with reference to figure 2.
Step 72: if the RB resource allocation of the initial edge frequency band of mode 3 sub-district finishes, the RB that then obtains the edge band of adjacent area takies situation.
For example, if after RB18～RB13 assigns, also there is the edge customer that does not have allocations of edge frequency band RB resource in the mode 3 sub-district, and then the edge band of mode 3 sub-district can be expanded according to the situation that takies of the edge band of adjacent area.
For example, each sub-district is through the mutual HII message of X2 interface, and the RB that carries edge band separately in this HII message takies situation.For example, pattern 2 sub-districts are through also idle two RB of its edge band that takies of HII message informing mode 3 sub-district.Since pattern 2 sub-districts be from the low frequency to the high frequency direction on Resources allocation, if idle two RB, two then idle RB are RB11 and RB12.
Step 73:, then take the idle RB resource of the initial edge frequency band of pattern 2 sub-districts, the edge band of the mode 3 sub-district after obtaining expanding if the initial edge frequency band of pattern 2 sub-districts has the free time.
For example, two idle RB of pattern 2 sub-districts are RB11 and RB12, and the required edge band in mode 3 sub-district is equal to, or greater than 8 RB, and then the edge band of the mode 3 sub-district after the expansion comprises RB13～RB18 and RB11, RB12.Certainly, the required edge band in mode 3 sub-district greater than 6 RB but less than 8 RB, be 7 RB like required edge band, then can only take among the idle RB in pattern 2 sub-districts, for example, preferential expansion takies RB12.
Step 74:, then take the idle RB of the initial edge frequency band of pattern 1 sub-district if after taking the idle RB of pattern 2 cell initial edge bands, the mode 3 sub-district also needs edge band.
For example, the idle RB number of pattern 1 utilizing cell edge frequency band does, if the edge band RB number that this moment, the mode 3 sub-district still needed is δ, the edge band RB number that then needs contention mode 1 sub-district be λ=min (c, δ).Send HII message through the X2 mouth and give adjacent area, λ RB resource of contention mode 1 sub-district front end.
Specific as follows, if after the mode 3 sub-district takies 2 idle RB of pattern 2 sub-districts, also need 2 RB,, then take 2 RB of pattern 1 sub-district high frequency if the idle RB number in pattern 1 sub-district is equal to, or greater than 2 RB, promptly take RB5 and RB6.
Certainly, if the edge customer of pattern 1 or pattern 2 sub-districts increases, in the time of need taking more edge band resource, then preferentially take the RB that is taken by the mode 3 sub-district, the edge band resource that the mode 3 sub-district needs rollback to take at this moment.For example, pattern 2 sub-districts also need take a RB, and then RB11 also continues to be taken by pattern 2 sub-districts, and is no longer taken by the mode 3 sub-district.
Through the above-mentioned different method of salary distribution, can realize the variation of the edge band method of salary distribution.
At the commercial initial stage of LTE, load is lighter, and the central user allocation strategy is to distribute away from edge band; Like pattern 1 sub-district and mode 3 sub-district; The edge customer load is all lighter, and the central user of pattern 1 begins to distribute from front end, and the central user of mode 3 sub-district begins to distribute from low-frequency range; The center frequency-band of this sub-district will overlap with the edge band of adjacent area so, cause the central user loss of throughput comparatively serious.In order to reduce interference, can adopt following embodiment.
Fig. 9 is the method flow sketch map of second embodiment of the invention, comprising:
Step 91: this sub-district obtains the situation that takies of the edge band RB of adjacent area.
For example, pattern 1 sub-district is RB7 and RB8 through the edge band that HII message learn mode 2 sub-districts take, and the edge band that the mode 3 sub-district takies is RB16～RB18.
Step 92: this sub-district is not taken by the adjacent area in the RB of the center frequency-band of self resource on the RB as edge band RB, the user of control centre.
With reference to Fig. 2; The center frequency-band of pattern 1 sub-district self is RB7～RB18; Suppose that the RB that the adjacent area takies as edge band RB is RB7, RB8, RB16～RB18, then pattern 1 sub-district will be in (RB7～RB18)-(RB7+RB8+RB16～RB18), the i.e. last scheduling of RB9～RB15 central user.
Present embodiment takies situation through obtaining the adjacent area edge band, combines the center frequency-band situation of self again, can utilize band resource more rationally, fully, improves the performance index of network.
