Interactive resource coordination information can be following any and combinations thereof：To this cell using and/or the resource that will use（Referred to herein as resource include one or more of：Space, time, frequency and power resource）Statement, to this cell using and/or the statement of the occupation mode of resource that will use, the status information of this cell.Wherein, for channel resource, resource coordination refers to whether the transmitting of adjacent cell or receiving channel can be configured as providing service for the terminal of adjacent cell.Such as, radio node A can have two kinds of borrow modes when the component frequency resource b of this cell is borrowed into the terminal to portion's cell, a kind of mode is while b is borrowed into the edge customer to adjacent cell, the wireless terminal of the central area of this cell still receives the business provided by the radio node of this cell using b, the UE that now transmitting or receiving channel resource of the radio node of this cell on b remains as this cell takes, therefore, transmitting or receiving channel resource on b can not be borrowed by adjacent cell；Another way is that radio node A borrows b after the edge customer to adjacent cell, and the wireless terminal of this cell does not use b, in this case, and transmittings or receiving channel resource of the radio node A on b can also be borrowed by adjacent cell.Specifically, this cell using and/or the resource declarations that will use include it is following any and combinations thereof：The power configuration for the time/frequency source block that the emission space orientation or/and angle of coverage width, this cell for the time/frequency source block that the time for the time/frequency source block that this cell takes and frequency location, this cell take take；This cell using and/or the statement of the occupation mode of resource that will use include the statement to mode is used as described below：In special time, space, frequency some resources are used in the way of this cell is exclusive；Some resources are used in the way of being shared with adjacent cell in special time, space, frequency；The status information of this cell includes：The load in time/frequency source block that this cell takes is indicated.Wherein, to this cell using and/or the occupation mode of resource that will use be claimed as exclusive mode in the case of, resource coordination information further comprises at least one of：The angular width information of this cell excipient wave beam, the saltus step information of the launch angle of this cell excipient wave beam spatially；To this cell using and/or the occupation mode of resource that will use be claimed as sharing mode in the case of, resource coordination information further comprises at least one of：The holding time pattern or time pattern number of frequency hopping pattern of this cell in the specific general resources of frequency i or frequency hopping pattern numbering, this cell to specific frequency spectrum resource.In addition, the status information of this cell includes business state information, network state information etc..And network state information is specifically included：To the measurement amount of adjacent cell（The handover measurement amount carried out such as terminal）, this cell loading condition, the disturbed condition of this cell, the quantity of cell-edge terminals and portfolio etc.；Interaction frequency can be divided into high time delay interaction and the interaction of 4Shi time delays；High time delay interaction can be using a few tens of milliseconds as the cycle；The interaction of family name's time delay can be with several milliseconds, for the cycle, such as, and each wireless sub-frame completes an interaction,
Wireless son it is small it is loyal be lms ~ 5ms. it is further to note that, when this cell radio node is simultaneously when Duo Group several adjacent cell radio nodes are adjacent, its resource coordination information interacted is the synthesis of the resource status of multigroup several the adjacent cell radio nodes adjacent to its.(three）Step faints S106 in step Sudden, and this cell radio node determines that the operation of used resource in following special time period of its own and several adjacent cell radio nodes can be following any：Operation 1:This cell radio node is ranked up to the priority of this cell and adjacent cell；This cell radio node is realized to this cell and the resource allocation of adjacent cell according to priority ranking and predetermined resource allocation rule, and preferably, this cell radio node uses list in the resource for locally forming this cell and adjacent cell；Operation 2:This cell radio node is ranked up to the gesture of this cell and adjacent cell;Sequence and predetermined resource allocation rule of this cell radio node according to pair potential, are realized to this cell and the resource allocation of adjacent cell, and preferably, this cell radio node uses list in the resource for locally forming this cell and adjacent cell.Wherein, can be according to cell load in operation 1（Operate 1-1) or resource utilization（Operation 1-2) determine the priority of cell, so, the cell of highest priority for pack heaviest cell or the utilization rate highest cell to the resource block that conflicts；And in above-mentioned operation 2, the gesture of cell can be determined according to the numbering or geographical coordinate of cell radio node.For example, order numbering is minimum（Or it is maximum）Cell " gesture " it is maximum, in another example, can be according to from the east to the west（Or from west to east）, from south to north（Or from north to south）, from top to bottom（Or from top to bottom）Order determine the gesture of radio node, sequentially come foremost according to this（Or it is rearmost）Cell its " gesture " is maximum.Above-mentioned operation can be applied in combination, for example, in the case of two cells have identical load, affected 1-1 will be unable to implement, at this point it is possible to be further introduced into operation 2;In the case where having same asset utilization rate in two cells, operation 1-2 will be unable to implement, and can now be further introduced into operation 2.Predetermined resource allocation rule above-mentioned described in detail below.The resource allocation rule can be：During resource is distributed to this cell and adjacent cell, state that the resource used states that the resource used can avoid the cell conflicted in space, time, any dimension of frequency with other cells for it,
The radio node of cell uses the resource that it is stated in special time period；On the other hand, during resource is distributed to this cell and adjacent cell, state that the resource used states that the resource used all has the cell conflicted in space, time, any dimension of frequency with other cells for it, this cell radio node causes the cell with limit priority or highest gesture in the cell that there is resource declarations conflict to occupy its resource stated so that the low cell of priority abandons the resource of its statement.And for the cell for the resource for abandoning its statement, this cell is in a radio frames, according to the priority orders or the height of gesture of the cell for the resource for abandoning its statement, in the resource dimension of time, frequency, space angle, the order that one or more combinations according to predetermined time, frequency, angle are formed, the resource that the cell is stated can be met by being searched in the vacant resource of presence.Specifically, the principle of lookup resource can be：In the cell of resource of its statement is not got, the cell of highest priority finds available resources in this radio frames first（Resource block), since the starting of this radio frames, first can meet the resource block for the resource that the radio node is stated（Group）It is used as the resource for distributing to the radio node.And if the cell for not getting the resource of its statement searches the resource stated less than oneself in a radio frame, resource will be abandoned and use statement.By above-mentioned processing, minizone resource can be avoided to use upper direct conflict, particularly avoid using upper conflict in resource between cell-edge terminals.In this step, interference sensitivity of this cell radio node according to adjacent cell in the frequency that this cell radio node is used, coordinates power resource of this cell in frequency and uses.For example, being limited in the maximum transmission power in these frequency resources, adjustment user on these frequencies or business arrangement etc..It so can further reduce inter-cell interference.It is further preferred that in step s 106, this cell radio node can also determine the occupation mode to resource except determining the resource that its own and several adjacent cell radio nodes are used in following special time period.For example, the determination to the occupation mode of resource can be realized by handling as follows：（1) occupation mode for the resource that this cell radio node is stated its own and several adjacent cell radio nodes is counted, and will state resource using mode of the most resource using mode of number of times as this cell and portion's cell；If there is two or more equal resource using mode of statement number of times, then resource using mode of the resource using mode stated the cell with limit priority or highest gesture as this cell and adjacent cell；Or（2) resource using mode of the resource using mode for being stated the cell with limit priority or highest gesture as this cell and adjacent cell.
In resource coordination method according to embodiments of the present invention, only using an arbitrary cells as this cell exemplified by be illustrated, from the point of view of the overall process form and result that multiple adjacent cells are constituted, this cell radio node and several adjacent cell radio nodes difference are in different geographical locations, according to resource coordination method according to embodiments of the present invention, the resource coordination information of this cell and its adjacent cell is handled with completely the same processing rule, in one group of adjacent cell that this cell is picked out, all formation one is corresponding with this group of neighbouring relations respectively, identical resource uses list.That is, when adjacent cell radio node mentioned above is as this cell radio node, its processing procedure is also as described above.The present invention further will be described by instantiation below.It is a kind of be used for implement resource coordination between cells method according to embodiments of the present invention wireless access network as shown in Fig. 2 including：Radio node 201a ~ 201g, two wireless terminals 202a and 202b.Each radio node is covered each by different cells, the central area of each cell（Shadow region）Frequency reuse be 1.In the fringe region of each cell, realized and covered using 1/3 frequency reuse.Wireless terminal 202a is in the fringe region of WAP 201a coverage cells, and wireless terminal 202b is in the fringe region of WAP 201g coverage cells.In the network planning, it is assumed that its numbering is respectively：Radio node 201a--->2000-001 radio nodes 201b--->The c of 2000-002 radio nodes 201-->2000-003 radio nodes 201d--->2000-004 radio nodes 201e->2000-005 radio nodes 201f->2000-006 radio nodes 201g->2000-007 carries out resource coordination in said system using the resource coordination method of minizone according to embodiments of the present invention.First, for example, in time interval 1, each radio node determines the neighbouring relations of oneself first, here, each radio node selects seven neighbouring base stations as its neighbor base station, that is, N=7, also, for each radio node, N is 7;
Then, each radio node determines to whether there is cell-edge terminals in the region of oneself covering.Radio node 201a ■ are according to RSRP (Reference symbol received power) measurement amount for being used to switch blunt wireless terminal 202a upper 4, and it is edge termination to determine wireless terminal 202a（Because including the pilot tone of two adjacent cells for exceeding intensity pre-determined threshold in the RSRP that wireless terminal 202a is reported：), and this edge termination 202a position is near this cell and WAP 201g coverage cells, the boundary of WAP 201f coverage cells（Because the WAP 201g that wireless terminal 202a is reported, WAP 201f RSRP intensity exceed pre-determined threshold);As radio node 201a process and method, RSRP (Reference symbol received power) measurement amount for being used to switch that radio node 201g is reported according to wireless terminal 202b, it is edge termination to determine wireless terminal 202b, and this edge termination 202b position is near this cell and WAP 201g coverage cells, the boundary of WAP 201f coverage cells.Next, for example, in time interval 2, in order to allow wireless terminal 202a to send data to its month business node wireless node 201a with high-speed, radio node 201a statements are used for the resource block that cell edge is covered using WAP 201g, WAP 201f is belonged to（As shown in figure 3, in figure 3, " serving cell " marked is " this cell ", " adjacent cell " marked is " adjacent cell "）, and this resource is sent to by X2 interfaces by WAP 201g, WAP 201f using statement;In order to allow wireless terminal 202b to send data to its service node radio node 201g with high-speed, radio node 201g statements are used for the resource block that cell edge is covered using WAP 201a, WAP 201f is belonged to（As shown in Figure 3）, and this resource is sent to by X2 interface by WAP 201a, WAP 201f using statement;In this process (time interval 2), oneself is equally sent to the adjacent cells such as WAP 201a, WAP 201g by radio node 201f without using the information of any general resources of frequency i.Finally, for example, in time interval 3, carrying out resource coordination between cells.Due to WAP 201a, WAP 201g itself resources stated and the resource contention of other side's statement, thus according to predetermined resource allocation rule described above（Or referred to as conflict arbitration mechanism）In concrete operations be mediated.It is for instance possible to use the operation 2 being mentioned above.So, WAP 201a, WAP 201g determine its " gesture " according to respective numbering, and the principle used here is：The sequence number of radio node is smaller, then its " gesture " is bigger.Radio node 201a numbering is 2000-001, and radio node 201g numbering is 2000-007, therefore, and radio node 201a " gesture " is more than radio node 201g
" gesture ", therefore, by radio node 201a use its state resource, and radio node 201g then can using first of this radio frames can meet its resource use state resource set of blocks in corresponding resource block as oneself future usage resource.After clash handle, the situation that WAP 201a, WAP 201g obtain resource is as shown in Figure 4（In Fig. 4, " the moon blunt business cell " marked is " this cell ", " 4) 5 nearly cell " i.e. " the 4p cells " marked).Examples detailed above, which describes 4 bars each radio nodes, is used for the situation of the coordination of the resource block that cell edge is covered to the terminal of fringe region, but the resource block that can be equally used on the whole frequency band wireless access network of the method for the invention coordinates the situation to the terminal of fringe region.In addition, examples detailed above is the implementation method provided by uplink exemplified by the coordination of resource, but the downlink resource 1 that the method for the invention provided can be equally used for minizone does tune.In summary, by means of the present invention, pass through the interaction of minizone, cell can be caused independently to determine its resource use and mode of operation in following special time, both it can realize that the resource to minizone on the whole frequency band of wireless access network carried out dynamic coordinate, resource that can also be to minizone on specific partial-band carries out dynamic coordinate, so as to so that the available resources of cell-edge terminals expand to whole system frequency band, realize the optimization of minizone resource distribution, the optimization of throughput of system, and then can lift wireless terminal and transmission rate.The preferred embodiments of the present invention are the foregoing is only, are not intended to limit the invention, for those skilled in the art, the present invention there can be various modifications and variations.Within the spirit and principles of the invention, any modification, equivalent substitution and improvements made etc., should be included in the scope of the protection.
