And dynamic I CIC is meant that network usually can be in real time notifies adjacent sub-district to carry out scheduling of resource (base station is often through transmitting base station adjustment resource allocation that load indication information (LoadInformation) informs adjacent sub-district to reduce presence of intercell interference on X2 interface) according to this cell load and disturbed condition, the resource allocation that load of also can be in real time notifying through the mode of sending Load Information according to adjacent sub-district and disturbed condition are adjusted this sub-district.Dynamic I CIC is a kind of dynamic cell resource scheduling scheme of full rate, and spectrum efficiency is higher.
In the prior art, to dynamic I CIC, general way is the situation of base station according to distribution of this local resource and load interference at present, sends the Load Information that carries these situation information to all adjacent cell base stations.The defective of this mode that prior art adopts is; Do not consider this sub-district and the not duplicate usually situation of different adjacent presence of intercell interference degree; The result who causes can carry out unnecessary resource adjustment to the less adjacent sub-district of actual interference, has influenced the total quality of network on the contrary, and; For the less adjacent sub-district of actual interference; Though need not it is carried out the resource adjustment, this cell base station still can send Load Information to this neighbour's cell base station, this also can cause some unnecessary wastings of resources.

Embodiment
In order to solve the problem that the load indication information send mode that exists in the prior art may influence network quality and cause the unnecessary wasting of resources; The inventor is to Long Term Evolution (LTE as shown in Figure 1; Long-Tcrm Evolution) the Cellular Networks networking sketch map of system is analyzed; Listed the chief component in the LTE system in this sketch map, having comprised: the adjacent sub-district (being the adjacent sub-district of sub-district 1 like sub-district 2~7) of base station (like the base station among Fig. 1 1~4), user terminal, Target cell (sub-district 1 among the figure) and Target cell.
Based on system as shown in Figure 1; In dynamic ICIC scheme; The load and the disturbed condition of sub-district 1 can be added up in base station 1 under the sub-district 1, and Load Information is sent in affiliated respectively base station (comprising base station 2~4), the adjacent sub-district of all in adjacent cell list then.In fact, suppose that the user terminal that is currently located at sub-district 1 is in the fringe region that is close to sub-district 7 in the sub-district 1, then usually; The suffered interference of this user terminal mainly is to derive from sub-district 7 (in this case; Sub-district 7 can be called " main interference source sub-district "), but the scheme that adopts prior art to provide, main interference source sub-district can not gone to distinguish in base station 1; But can Load Information be sent to base station 2~4; Thereby can make that the signaling transport overhead between the base station is bigger, and, unnecessary signaling process and the scheduling of resource operation in base station under the non-main interference source sub-district also can be caused.
Can know through above-mentioned analysis; The suffered interference of user terminal generally derives from main interference source sub-district; If can from the adjacent sub-district of Target cell, determine main interference source sub-district; Then can only need carry out ICIC and just can satisfy the purpose that reduces the suffered interference of user terminal significantly those main interference source sub-districts, and, unnecessary signaling process and the scheduling of resource operation in base station under the non-main interference source sub-district also can not caused.Particularly; Based on system as shown in Figure 1, if can determine the main interference source sub-district of user terminal, then only under these main interference source sub-districts the base station send Load Information; Such as; To situation shown in Figure 1, only send the scheduling of resource of Load Information, and do not send Load Information) to base station 2,3 with realization base station 4 to base station 4; So just avoid the unnecessary scheduling of 2, the 3 pairs of resources in base station, thereby can not cause the problem of the network quality variation and the unnecessary wasting of resources.
By above-mentioned analysis, the inventor has proposed a kind of delivery plan of load indication information.Below in conjunction with accompanying drawing, the scheme that the embodiment of the invention is provided is described in detail.
At first, the embodiment of the invention provides a kind of sending method of load indication information, and the idiographic flow sketch map of this method is as shown in Figure 2, may further comprise the steps:
The signal strength information of the adjacent sub-district of the Target cell that base station reception user terminal sends under the step 21, Target cell, and confirm adjacent cell ID;
Step 22; The Load Information that send according to base station under the information of radio resource allocation of the signal strength information that receives, Target cell and each the adjacent sub-district base station under the Target cell; From the adjacent cell ID of confirming, confirm the disturbance regime of Target cell is met the sign of the adjacent sub-district of interference of predetermined disturbance regime;
The Load Information that comprises the sign of disturbing adjacent sub-district is sent in the base station in the base station under the step 23, Target cell under the sub-district of disturbing adjacent cell ID indication.
The said method that provides through the embodiment of the invention; The base station is after determining the sign of the adjacent sub-district of interference that disturbance regime to Target cell meets predetermined disturbance regime under the Target cell; The base station is sent Load Information and is realized the adjustment to resource under the sub-district that the sign of the adjacent sub-district of the interference of confirming is indicated; Rather than need under all adjacent sub-districts, realize adjustment by base station transmission Load Information to resource; Therefore; Said method is when reaching resource adjustment purpose; Need not base station transmission Load Information under the adjacent sub-district less, disturb affiliated base station, less adjacent sub-district also to need not resource is carried out unnecessary adjustment, thereby can solve the problem that the load indication information send mode that exists in the prior art may influence network quality and cause the unnecessary wasting of resources the interference of Target cell.
In the embodiment of the invention,, can also further improve, below introduce in detail the concrete improvement that said method is done said method in order to reach better technique effect.
With Fig. 1 is example; The adjacent sub-district of sub-district 1 is sub-district 4,5,6,7; In theory, sub-district 4~7 all can produce certain interference to sub-district 1, yet; As far as the user terminal in the sub-district 1, to its adjacent sub-district that produces larger interference be generally with this user terminal geographically relatively near adjacent sub-district.As shown in Figure 1, with the user terminal close together be sub-district 7.In embodiments of the present invention, in order accurately to confirm and the sign of the adjacent sub-district of user terminal close together that in above-mentioned steps 21, the base station confirms that the process of adjacent cell ID just can realize through sub-steps under the Target cell:
At first, the base station receives the adjacent cell ID that user terminal sends under the Target cell, such as, the user terminal among Fig. 1 can be confirmed the sign of adjacent sub-district 4~7 through the mode of adjacent cell measurement;
Then; The direction of arrival angle of user terminal with respect to base station under the Target cell confirmed in the base station under the Target cell; And the relative angular orientation between the base station under affiliated base station, definite respectively each adjacent sub-district and the Target cell; Such as, can no longer those algorithms be given unnecessary details at this with reference to definite direction of arrival angles such as Capon algorithm of the prior art, linear prediction algorithm, MUSIC algorithms.Need to prove that for the comparison at follow-up realization relative angular orientation and direction of arrival angle, direction of arrival angle and relative angular orientation should confirm that benchmark confirms according to same angle;
At last, according to the difference between direction of arrival angle and each relative angular orientation, from the sign of the adjacent sub-district that receives, choose sign, as the adjacent cell ID of confirming less than the pairing adjacent sub-district of difference of predetermined angular threshold value.
Through above-mentioned substep; Be equivalent to realize the accurate location of user terminal; Also from the adjacent cell ID that user terminal sends, more accurately filter out the sign of nearer adjacent sub-district, distance users terminal simultaneously; And owing to adjacent sub-district far away, distance users terminal is generally less to the interference of this user terminal, therefore can ignores those user terminal is disturbed less adjacent sub-district and it does not carried out the resource adjustment.
In addition, in the ordinary course of things, it is bigger to be in the interference that the user terminal of cell edge often receives, and therefore, the user terminal that can preferably be in cell edge in the embodiment of the invention is investigated the disturbed condition of minizone.In order to realize this purpose, before the above-mentioned steps 21, can further include step:

At last, the second Physical Resource Block information corresponding adjacent cell ID consistent with the first Physical Resource Block information matches confirmed as the sign of disturbing adjacent sub-district.
Need to prove in addition; Before the step 23 of the said method that the embodiment of the invention provides; Can also confirm further that definite mode of this resource dispatching strategy can be to confirm according to the load indication information that send base station under the information of radio resource allocation of the signal strength information of confirming, Target cell and each the adjacent sub-district to the resource dispatching strategy that disturbs adjacent sub-district.Such as; Based on above-mentioned steps; After determining the second Physical Resource Block information consistent, just can confirm that the resource dispatching strategy that corresponding adjacent sub-district is carried out scheduling of resource is " the adjustment Resource Block uses second Physical Resource Block to avoid user terminal " with the first Physical Resource Block information matches.Again such as; Based on above-mentioned steps; When confirming the second consistent Physical Resource Block information of the first Physical Resource Block information matches more after a little while, can confirm that also corresponding resource dispatching strategy is " can need not the distribution of Resource Block is adjusted " or " only to adjusting with the consistent part Resource Block of first Resource Block coupling in second Physical Resource Block " etc.
After determining resource dispatching strategy, the base station just can be carried on the sign of resource dispatching strategy of confirming and corresponding interference neighbour sub-district in the load indication information when the load indication information is sent in the base station under the Target cell, sends to relevant base station.
