So-called static ICIC mainly refers to that network based pre-configured resource is distributed and power control scheme carries out user's scheduling, and the system resource that this scheme is distributed in whole network operation process does not change according to the variation of user and business.Typical static ICIC method has partial frequency multiplexing (FFR, FractionalFrequcncy Reuse) method and soft-frequency reuse (SFR, Soft Frequency Reuse) method etc.The advantage of static ICIC is to realize simply, can not cause larger burden to network signal, and shortcoming is that scheduling of resource flexibility is low, cannot change and adjust and optimize according to Network.And because static ICIC often only adopts partial-band resource to avoid interference at cell edge, frequency reuse is greater than 1, thereby can make the availability of frequency spectrum decline, cause spectrum efficiency to have certain loss.
And dynamic I CIC refers to that network conventionally can be in real time carries out scheduling of resource (base station often inform by transmit load instruction information (LoadInformation) on X2 interface the base station adjustresources of adjacent cell divides to be equipped with reduce presence of intercell interference) according to this cell load and disturbed condition notice adjacent cell, the resource of also can be in real time adjusting this community according to adjacent cell by the load that sends the mode of Load Information and notify and disturbed condition is distributed.Dynamic I CIC is a kind of dynamic cell resource scheduling scheme of full rate, and spectrum efficiency is higher.
In the prior art, for dynamic I CIC, at present general way is that base station is distributed according to this local resource and the situation of load disturbance, sends the Load Information that carries these situation information to all adjacent cells base station.The defect of this mode that prior art adopts is, do not consider between this community and different adjacent cell annoyance level not duplicate situation conventionally, the result causing is probably to carry out unnecessary resource adjustment to the less adjacent cell of actual interference, affected on the contrary the total quality of network, and, for the less adjacent cell of actual interference, although without it is carried out to resource adjustment, but this cell base station still can send Load Information to this adjacent cell base station, and this also can cause some unnecessary wastings of resources.

Embodiment
The problem that may affect network quality and cause the unnecessary wasting of resources in order to solve the load instruction information send mode existing in prior art, inventor is to Long Term Evolution (LTE as shown in Figure 1, Long-Tcrm Evolution) the Cellular Networks networking schematic diagram of system is analyzed, in this schematic diagram, listed the chief component in LTE system, having comprised: the adjacent cell of base station (as the base station 1～4 in Fig. 1), user terminal, Target cell (Tu Zhong community 1) and Target cell (as community 2～7 is the adjacent cell of community 1).
System based on as shown in Figure 1, in dynamic ICIC scheme, base station 1 under community 1 can statistics community 1 load and disturbed condition, then to all adjacent cells in adjacent cell list, the base station (comprising base station 2～4) under respectively sends Load Information.In fact, suppose that the user terminal that is currently located at community 1 is close to the fringe region of community 7 in community 1, usually, the suffered interference of this user terminal is mainly to derive from community 7 (in this case, community 7 can be called " main interference source community "), but the scheme that adopts prior art to provide, main interference source community can not gone to distinguish in base station 1, but Load Information can be sent to base station 2～4, thereby can make the signalling expense between base station larger, and, under also can causing non-main interference source community, the unnecessary signaling in base station is processed and scheduling of resource operation.
Known by above-mentioned analysis, the suffered interference of user terminal generally derives from main interference source community, if can determine main interference source community from the adjacent cell of Target cell, can only need to carry out ICIC to those main interference source communities just can meet and significantly reduce the object that user terminal is disturbed, and, also can not cause unnecessary signaling processing and the scheduling of resource operation in base station under non-main interference source community.Particularly, system based on as shown in Figure 1, if can determine the main interference source community of user terminal, then only to base station under these main interference source communities, send Load Information, such as, for the situation shown in Fig. 1, only to base station, 4 send Load Information to realize the scheduling of resource of base station 4, and to base station, 2,3 do not send Load Information), so just avoid the unnecessary scheduling of 2, the 3 pairs of resources in base station, thereby can not cause the problem of network quality variation and the unnecessary wasting of resources.
By above-mentioned analysis, inventor has proposed a kind of delivery plan of load instruction information.Below in conjunction with accompanying drawing, the scheme that the embodiment of the present invention is provided is described in detail.
First, the embodiment of the present invention provides a kind of sending method of load instruction information, and the idiographic flow schematic diagram of the method as shown in Figure 2, comprises the following steps:
Step 21, the signal strength information of the adjacent cell of the Target cell that under Target cell, base station reception user terminal sends, and definite adjacent cell sign;
Step 22, base station is according to the Load Information that under the information of radio resource allocation of the signal strength information receiving, Target cell and each adjacent cell, sends base station under Target cell, from definite adjacent cell sign, determine the sign that the disturbance regime of Target cell is met to the interference adjacent cell of predetermined disturbance regime;
Step 23, under the community that under Target cell, indicate to the adjacent cell ID of interference base station, base station sends the Load Information that comprises the sign of disturbing adjacent cell.
The said method providing by the embodiment of the present invention, under Target cell, base station is after determining the sign of the interference adjacent cell that the disturbance regime of Target cell is met to predetermined disturbance regime, under the community of indicating to the sign of definite interference adjacent cell, base station sends Load Information and realizes the adjustment to resource, rather than need to realize the adjustment to resource to base station transmission Load Information under all adjacent cells, therefore, said method is when reaching resource adjustment object, without to base station under the less adjacent cell of the interference of Target cell is sent to Load Information, under disturbing less adjacent cell, base station is also without resource is carried out to unnecessary adjustment, thereby can solve the problem that the load instruction information send mode existing in prior art may affect network quality and cause the unnecessary wasting of resources.
In the embodiment of the present invention, in order to reach better technique effect, can also be further improved said method, below introduce in detail the concrete improvement that said method is done.
Take Fig. 1 as example, the adjacent cell of community 1 is community 4,5,6,7, in theory, 4～7 Dou Huidui communities 1, community produce certain interference, yet, for the user terminal in community 1, the adjacent cell that it is produced to larger interference is generally the adjacent cell geographically more close with this user terminal.As shown in Figure 1, with user terminal close together Wei community 7.In embodiments of the present invention, in order accurately to determine and the sign of the adjacent cell of user terminal close together, in above-mentioned steps 21, under Target cell, base station determines that the process of adjacent cell sign just can realize by following sub-step:
First, under Target cell, base station receives the adjacent cell sign that user terminal sends, such as, the user terminal in Fig. 1 can, by the mode of adjacent cell measurement, be determined the sign of adjacent cell 4～7;
Then, under Target cell, base station determines that user terminal is with respect to the direction of arrival angle of base station under Target cell, and determine respectively the relative angular orientation between base station and affiliated base station, Target cell under each adjacent cell, such as, can, with reference to definite direction of arrival angles such as Capon algorithm of the prior art, linear prediction algorithm, MUSIC algorithms, at this, no longer those algorithms be repeated.It should be noted that, for the follow-up comparison that realizes relative angular orientation and direction of arrival angle, direction of arrival angle and relative angular orientation should determine that benchmark determines according to same angle;
Finally, according to the difference between direction of arrival angle and each relative angular orientation, from the sign of the adjacent cell that receives, choose the sign of the corresponding adjacent cell of difference that is less than predetermined angular threshold value, as definite adjacent cell sign.
By above-mentioned sub-step, be equivalent to realize the accurate location of user terminal, the adjacent cell sign simultaneously also sending from user terminal, more accurately filter out the sign of the nearer adjacent cell of distance users terminal, and because distance users terminal adjacent cell far away is generally less to the interference of this user terminal, therefore can ignore those user terminal is disturbed and it does not carried out to resource adjustment compared with little adjacent cell.
In addition, in the ordinary course of things, the interference that the user terminal in cell edge is often subject to is larger, therefore, in the embodiment of the present invention, can preferably in the user terminal of cell edge, investigate the disturbed condition of minizone.In order to realize this purpose, before above-mentioned steps 21, can further include step:
Under Target cell, user terminal, according to the wireless parameter measurement result of user terminal to send up, is determined behind edge, Target cell in base station, to user terminal, sends measuring control information.Thereby in step 21, the signal strength information that under Target cell, base station receives is exactly in this user terminal at edge, Target cell, to receive the signal strength information of the adjacent cell measuring after measuring control information.
In the embodiment of the present invention, the improvement of said method is also embodied in to the signal strength information of the adjacent cell that is greater than predetermined signal strength threshold value that base station receives under Target cell signal strength information can send for user terminal.The signal that is not more than this threshold value due to signal strength information is less to the interference of user terminal, generally can ignore it, therefore, can according to predetermined signal strength threshold value, to signal strength information, once be filtered by user terminal, the benefit of operation is also like this, can save user terminal and send the required resource of this part signal strength information that is not more than predetermined signal strength threshold value.
It should be noted that, the load instruction information that under the Target cell of mentioning in above-mentioned steps 22, base station sends according to base station under the resource allocation information of signal strength information, Target cell and each adjacent cell, determine that the sign that the disturbance regime of Target cell is met to the interference adjacent cell of predetermined disturbance regime can have various ways, such as, the step that wherein a kind of mode comprises is as follows:
First, the sign that is greater than the first adjacent cell that the signal strength information of predetermined signal strength threshold value is corresponding, according to signal strength information, is chosen in base station from definite adjacent cell sign under Target cell;
Then, under Target cell, base station is according to the resource allocation information of Target cell, determine the first physical resource block message that user terminal is shared, the load instruction information sending according to base station under the first adjacent cell, determine the second shared physical resource block message of user terminal in the first adjacent cell, and by comparing the first physical resource block message and the second physical resource block message, determine the second physical resource block message consistent with the first Physical Resource Block information matches;
Finally, adjacent cell sign corresponding to the second physical resource block message consistent with the first Physical Resource Block information matches is defined as disturbing the sign of adjacent cell.
In addition it should be noted that, before the step 23 of the said method providing in the embodiment of the present invention, can also further determine for the resource dispatching strategy that disturbs adjacent cell, definite mode of this resource dispatching strategy can be that the load instruction information sending according to base station under the information of radio resource allocation of definite signal strength information, Target cell and each adjacent cell is determined.Such as, based on above-mentioned steps, after determining the second physical resource block message consistent with the first Physical Resource Block information matches, just can determine that the resource dispatching strategy that corresponding adjacent cell is carried out to scheduling of resource is " adjustresources piece is to avoid user terminal to use the second Physical Resource Block ".Again such as, based on above-mentioned steps, when determining that the second physical resource block message that the first Physical Resource Block information matches is consistent is when less, also can determine that corresponding resource dispatching strategy is " can adjust without the distribution to Resource Block " or " only to mating consistent part Resource Block with first resource piece in the second Physical Resource Block, adjusting " etc.
After determining resource dispatching strategy, when Xiang base station, base station sends load instruction information under Target cell, just the sign of definite resource dispatching strategy and corresponding interference adjacent cell can be carried in load instruction information, send to corresponding base station.
In the step comprising at aforesaid way, the sign of the adjacent cell that the signal strength information that is greater than predetermined signal strength threshold value of predetermined number is corresponding also can be chosen at random in base station from definite adjacent cell sign under Target cell, or corresponding to signal strength information order from high to low, from definite adjacent cell sign, choose at random successively the sign of the adjacent cell that the signal strength information of predetermined number is corresponding, etc.
