In order to avoid centralized CoMP, increase as introducing equipment cost caused by additional centerized fusion node, And the resource conflict problem for avoiding Distributed C oMP from occurring, in the embodiment of the present invention, propose a kind of based on token interaction There is association by minizone interface notification and locally for first base station by the method for Distributed C oMP, this method in first terminal set Make other base stations transmitted, and receive the second terminal set of other base stations return, determines current preference in second terminal set It is the highest continuous N number of terminal distribution of current priority when the highest continuous N number of terminal of grade is the terminal in local compass of competency Running time-frequency resource, and allocation result is recorded, and third terminal set and allocation result are passed through into minizone interface notification and local There are other base stations of cooperation transmission.

The preferred embodiment of the present invention is described in detail with reference to the accompanying drawing.

As shown in fig.3, the detailed process of the Distributed C oMP based on token interaction is as follows in the embodiment of the present invention:

Step 300: first terminal set is passed through minizone interface notification to first base station and locally there are cooperation transmissions Other base stations, and receive the second terminal set of other base stations return, wherein it include that first base station is current in first terminal set Terminal to be scheduled in the compass of competency of statistics includes current to be scheduled in other base station compasss of competency in second terminal set Terminal and first terminal set.

In the embodiment of the present invention, during executing step 300, if there is only other base stations, first base station First terminal set is directly notified into other base stations by cell interface, and directly receives the second terminal of other base stations return Set；

For example, first base station compass of competency in dispatch terminal be terminal A and terminal B, other base stations be the second base station, and It to dispatch terminal is terminal C and terminal D in second base station compass of competency, i.e. first terminal collection is combined into terminal A and terminal B, and second Termination set is combined into terminal A, terminal B, terminal C and terminal D, then, first terminal set is directly passed through minizone by first base station Interface directly notifies the second base station, the second base station to send first base station for second terminal set.

At least two other base stations if it exists, then first terminal set is passed through minizone according to preset order by first base station Interface first issues first other base station, is continued to be sent to other subsequent bases according to preset order by first other base station It stands and first base station receives the second terminal set returned by the last one other base station.

For example, to dispatch terminal being terminal A and terminal B in first base station compass of competency, other base stations are the second base station, the Three base stations and the 4th base station, and be terminal C and terminal D to dispatch terminal in the second base station compass of competency, model is administered in third base station To dispatch terminal it is terminal E in enclosing, to dispatch terminal is terminal F in the 4th base station compass of competency, i.e. first terminal collection is combined into end Hold A and terminal B, second terminal collection is combined into terminal A, terminal B, terminal C, terminal D, terminal E and terminal F, it is assumed that preset order according to It is secondary are as follows: first base station, the second base station, third base station and the 4th base station, then, first base station directly passes through first terminal set Terminal A, terminal B, terminal C and terminal D are passed through minizone interface notification the by the second base station of minizone interface notification, the second base station Terminal A, terminal B, terminal C, terminal D and terminal E are passed through the 4th base station of minizone interface notification by three base stations, third base station, the Four base stations by terminal A, terminal B, terminal C, terminal D, terminal E and terminal F by minizone interface notification first base station, i.e., the 4th Second terminal set is sent first base station by base station.

In conclusion first base station there are other base stations of cooperation transmission by carrying out the hair to dispatch terminal with local It send, finally obtains in cooperative base station to dispatch terminal set, i.e., the first round is completed in proper order by preset order, obtain cooperative base station Middle needed dispatch terminal set (cooperative base station is first base station and there are other base stations of cooperation transmission with local).

Step 310: first base station determines that the highest continuous N number of terminal of current priority is local pipe in second terminal set It is the highest continuous N number of terminal distribution running time-frequency resource of current priority, and record allocation result when having jurisdiction over the terminal in range, with And by minizone interface notification and locally, there are other base stations of cooperation transmission by third terminal set and allocation result；Its In, third terminal set is obtained after first base station updates second terminal set according to the allocation result of running time-frequency resource.

In the embodiment of the present invention, first base station by third terminal set and allocation result by minizone interface notification with Locally there are when other base stations of cooperation transmission, it can use but be not limited to following two mode:

First way: third terminal set and allocation result are passed through cell interface according to preset order by first base station It notifies and locally there are other base stations of cooperation transmission.

For example, other base stations be the second base station and third base station, preset order is successively are as follows: first base station, the second base station and Third base station, then, third terminal set and allocation result are sent to the second base station by first base station, then are determined by the second base station Need to send to dispatch terminal information and allocation result, and be sent to third base station.

The second way: third terminal set and allocation result are passed through cell interface according to specified sequence by first base station It notifies and locally there are other base stations of cooperation transmission；Wherein, sequence is specified are as follows: each terminal for including in second terminal set After carrying out priority ranking, the corresponding base station sequence of the terminal of priority from high to low.

For example, other base stations are the second base station and third base station, in first base station compass of competency is eventually to dispatch terminal A is held, in the second base station compass of competency is terminal B to dispatch terminal, and in the compass of competency of third base station is eventually to dispatch terminal C is held, and it (is using unified standard when calculating priority that the sequence of priority, which is followed successively by terminal A, terminal C and terminal B, The priority to dispatch terminal under different base station in compass of competency is calculated, in this way, the priority orders of all terminals are exhausted Pair), then setting sequence is successively are as follows: first base station, third base station and the second base station, then, first base station is by third terminal Set and allocation result are sent to third base station, then determine that need to send ties to dispatch terminal information and distribution by third base station Fruit, and it is sent to the second base station.

In practical applications, when executing step 310, if N=1, first base station determines current in second terminal set It is the highest terminal distribution time-frequency of current priority when one terminal of highest priority is the terminal in local compass of competency Resource, and allocation result is recorded, and third terminal set and allocation result are led to according to preset order by cell interface Know and locally there are other base stations of cooperation transmission；Third terminal set and allocation result can also be passed through according to specified sequence There are other base stations of cooperation transmission for minizone interface notification and local；

For example, as it is known that second terminal collection be combined into it is all currently to dispatch terminal in current cooperative base station compass of competency, respectively It is terminal A to dispatch terminal for terminal A, terminal B, terminal C, terminal D, terminal E and terminal F, and in first base station compass of competency It to dispatch terminal is terminal C and terminal D, end to be dispatched in the compass of competency of third base station in the second base station compass of competency with terminal B It holds and show that the priority orders in second terminal set are followed successively by terminal A, terminal C, end by calculating for terminal E and terminal F Hold D, terminal B, terminal E and terminal F.

If first base station is sent by preset order to dispatch terminal information and allocation result: assuming that preset order Successively are as follows: first base station, the second base station and third base station, then, first base station starts to distribute running time-frequency resource for terminal A, e.g., point The PRB for being 1 with frequency number, and by third terminal set (terminal B, terminal C, terminal D, terminal E and terminal F) and the distribution As a result (PRB that dividing frequency number is 1) is sent to the second base station, the updated terminal to highest priority in dispatch terminal C belongs in the second base station compass of competency, and the second base station is that terminal C distributes running time-frequency resource, e.g., the PRB that dividing frequency number is 2, And by terminal D, terminal B, terminal E and terminal F and all allocation results (PRB and distribution frequency that dividing frequency number is 1 at present The PRB that rate number is 2) it is sent to third base station, the terminal D of highest priority belongs in the compass of competency of third base station at this time, the Three base stations are that terminal D distributes running time-frequency resource, e.g., the PRB that dividing frequency number is 3, and by terminal B, terminal E and terminal F and All allocation results (PRB, the PRB that dividing frequency numbers the PRB for being 2 and dividing frequency number is 3 that dividing frequency number is 1) It is sent to first base station, first base station continues as terminal B distribution running time-frequency resource, and will be whole such as the PRB that dividing frequency number is 4 Hold E and terminal F and all allocation results (PRB that PRB that dividing frequency number is 1, dividing frequency number are 2, dividing frequency The PRB that PRB and the dividing frequency number that number is 3 are 4) it is sent to the second base station, since terminal E is not belonging to the administration of the second base station In range, then the second base station is not processed, and by terminal E and terminal F and all allocation results, (dividing frequency number is 1 The PRB that the PRB and dividing frequency number that PRB that PRB, dividing frequency number are 2, dividing frequency number are 3 are 4) it is sent to the Three base stations, third base station are that terminal E distributes running time-frequency resource, e.g., the PRB that dividing frequency number is 5, and by terminal F and own Allocation result (dividing frequency number be 1 PRB, dividing frequency number be 2 PRB, dividing frequency number be 3 PRB, distribution The PRB that PRB and the dividing frequency number that frequency number is 4 are 5) it is sent to first base station, first base station does not distribute video resource, It is again sent to the second base station, the second base station is not processed, and third base station is re-send to, at this point, third base station is terminal F distribution Running time-frequency resource, e.g., the PRB that dividing frequency number is 6 terminates to send operation (often for one to dispatch terminal distribution running time-frequency resource Afterwards, system can automatically update needed dispatch terminal information and all allocation results).

It is sent when dispatch terminal information and allocation result by preset order, if base station determines priority most It is high it is current to dispatch terminal in local compass of competency, then base station is the terminal distribution running time-frequency resource, and records allocation result, Then updated to dispatch terminal information and all allocation results according to preset order transmission, if base station determines highest priority It is current to which in the non-local compass of competency of dispatch terminal, then base station is directly sent out according to preset order without time-frequency resource allocating It serves secondary received to dispatch terminal information and allocation result.

If first base station is sent by specified sequence to dispatch terminal information and allocation result: first base station according to The priority of terminal determines specified sequence, terminal A, terminal C, terminal D, terminal B, terminal E and the corresponding base station sequence of terminal F Are as follows: first base station, the second base station, the second base station, first base station, third base station and third base station, then, first base station is terminal A distributes running time-frequency resource, e.g., the PRB that dividing frequency number is 1, and by third terminal set (terminal B, terminal C, terminal D, terminal E and terminal F) and the allocation result (PRB that dividing frequency number is 1) be sent to the second base station, the second base station is that terminal C divides With running time-frequency resource, the PRB that such as dividing frequency number is 2, and by terminal D, terminal B, terminal E and terminal F and all points at present It is sent to third base station with result (PRB that the PRB and dividing frequency number that dividing frequency number is 1 are 2), third base station is eventually D is held to distribute running time-frequency resource, e.g., the PRB that dividing frequency number is 3, and terminal B, terminal E and terminal F and all distribution are tied Fruit (PRB, the PRB that dividing frequency numbers the PRB for being 2 and dividing frequency number is 3 that dividing frequency number is 1) is sent to first Base station, first base station are that terminal B distributes running time-frequency resource, e.g., the PRB that dividing frequency number is 4, and by terminal E and terminal F and All allocation results (PRB that PRB that PRB that dividing frequency number is 1, dividing frequency number are 2, dividing frequency number are 3 and The PRB that dividing frequency number is 4) it is sent to third base station, third base station is that terminal E distributes running time-frequency resource, and e.g., dividing frequency is compiled Number be 5 PRB, third base station continue as terminal F distribution running time-frequency resource, e.g., dividing frequency number be 6 PRB, terminate send behaviour (often for one after dispatch terminal distributes running time-frequency resource, system can automatically update needed dispatch terminal information and all points to work With result).

It is sent when dispatch terminal information and allocation result by specified sequence, then base station directly determines preferentially Grade is highest currently to dispatch terminal in local compass of competency, and is the terminal distribution running time-frequency resource, and record allocation result, Then it sends updated to dispatch terminal information and all allocation results.

If N > 1, first base station determines that the highest continuous N number of terminal of current priority is local pipe in second terminal set It is the highest terminal distribution running time-frequency resource of current priority, and record allocation result when having jurisdiction over the terminal in range, and will Third terminal set and allocation result pass through minizone interface notification and other local there are cooperation transmission according to preset order Base station；Alternatively, distributing running time-frequency resource respectively for the highest continuous N number of terminal of current priority, and allocation result is recorded, and will By minizone interface notification and local, there are cooperation transmissions according to specified sequence for third terminal set and all allocation results Other base stations；

For example, as it is known that second terminal collection be combined into it is all currently to dispatch terminal in current cooperative base station compass of competency, respectively It for terminal A, terminal B, terminal C and terminal D, and in first base station compass of competency to dispatch terminal is terminal A and terminal B, second To dispatch terminal it is terminal C in the compass of competency of base station, to dispatch terminal is terminal D in the compass of competency of third base station, by calculating, Show that the priority in second terminal set is sequentially successively terminal A, terminal B, terminal D and terminal C.

If first base station is sent by preset order to dispatch terminal information and allocation result: assuming that preset order Are as follows: first base station, the second base station and third base station, then, first base station is that terminal A distributes running time-frequency resource, and e.g., dividing frequency is compiled Number PRB for being 1, and (dividing frequency number is 1 by third terminal set (terminal B, terminal C and terminal D) and the allocation result PRB) be sent to the second base station, it is updated to be not belonging to the second base station administration model to highest priority terminal B in dispatch terminal In enclosing, then by third terminal set (terminal B, terminal C and terminal D) and the allocation result, (dividing frequency is numbered for the second base station PRB for 1) it is sent to third base station, because the terminal B of highest priority is not belonging in the compass of competency of third base station, then third Base station is sent out by third terminal set (terminal B, terminal C and terminal D) and the allocation result (PRB that dividing frequency number is 1) Be sent to first base station, first base station is that terminal B distributes running time-frequency resource, as dividing frequency number be 2 PRB, and by terminal C and end End D and all allocation results (PRB that the PRB and dividing frequency number that dividing frequency number is 1 are 2) are sent to the second base Stand, since the terminal D of highest priority is not belonging in the second base station compass of competency, then the second base station is not processed, by terminal C and Terminal D and all allocation results (PRB that the PRB and dividing frequency number that dividing frequency number is 1 are 2) are sent to third base It stands, third base station is that terminal D distributes running time-frequency resource, e.g., the PRB that dividing frequency number is 3, and by terminal C and all distribution As a result (PRB that the PRB and dividing frequency number that PRB that dividing frequency number is 1, dividing frequency number are 2 are 3) is sent to the One base station, first base station are not processed, and are being sent to the second base station, and the second base station is that terminal C distributes running time-frequency resource, e.g., distribution The PRB that frequency number is 4 terminates to send operation.

If first base station is sent by specified sequence to dispatch terminal information and allocation result: first base station passes through The priority of terminal determines specified sequence, terminal A, terminal B, terminal D and the corresponding base station sequence of terminal C are as follows: first base station, the One base station, third base station and the second base station, then, first base station is that terminal A distributes running time-frequency resource, and e.g., dividing frequency number is 1 PRB, and continue as terminal B distribution running time-frequency resource, e.g., the PRB that dividing frequency number is 2, then by terminal C and terminal D with And all allocation results (PRB that the PRB and dividing frequency number that dividing frequency number is 1 are 2) are sent to third base station, third Base station is that the terminal D of current highest priority distributes running time-frequency resource, as dividing frequency number be 3 PRB, and by terminal C and (PRB and dividing frequency number that PRB that dividing frequency number is 1, dividing frequency number are 2 are 3 for all allocation results at present PRB it) is sent to the second base station, the second base station is that terminal C distributes running time-frequency resource, and e.g., the PRB that dividing frequency number is 4 terminates hair Send operation.

In addition, if first base station determines that the highest continuous N number of terminal of current priority is not local in second terminal set Second terminal set is then existed by minizone interface notification with local according to preset order and is cooperated by the terminal in compass of competency Other base stations of transmission.

For example, as it is known that second terminal collection be combined into it is all currently to dispatch terminal in current cooperative base station compass of competency, respectively It is terminal A to dispatch terminal for terminal A, terminal B and terminal C, and in first base station compass of competency, in the second base station compass of competency It is terminal B to dispatch terminal, to dispatch terminal is that terminal C by calculating obtains second terminal collection in the compass of competency of third base station Priority in conjunction is successively sequentially terminal B, terminal C, terminal A, it is assumed that preset order is successively are as follows: first base station, the second base station With third base station.So, when first base station determines terminal B not in local compass of competency, directly second terminal set is passed through Corresponding operation is done using mode same as first base station in the second base station of minizone interface notification, the second base station again, herein not It repeats again.

In conclusion sent in cooperative base station (first base station and with local there are other base stations of cooperation transmission) to Dispatch terminal information (it is each to dispatch terminal and to dispatch terminal priority and be to dispatch terminal distribution time-frequency money All allocation results in source) it is known as token, often for one after dispatch terminal distributes running time-frequency resource, system can automatically update all To dispatch terminal information and all allocation results, i.e. token is updated after dispatch terminal distributes running time-frequency resource with each , this Distributed C oMP based on token is to carry out time-frequency resource allocating according to the token of transmission, not only avoids resource Conflict, also improves the efficiency of distribution, refering to shown in Fig. 4.

Further, if first base station receives again and locally there are the 4th terminals that other base stations of cooperation transmission return The allocation result of set and all base stations distribution running time-frequency resource, and continue as belonging to local compass of competency and in the 4th termination set N number of terminal distribution running time-frequency resource of highest priority in conjunction, and distribute the 5th terminal set and all base stations to running time-frequency resource Allocation result other base stations are sent to by cell interface, wherein the 4th terminal set is that other base stations are provided according to time-frequency What the allocation result in source obtained after updating to third terminal set, the 5th terminal set is point of other base stations according to running time-frequency resource It is obtained after being updated with result to the 4th terminal set；Wherein, all base stations refer to first base station and there is the biography that cooperates with local Other defeated base stations.
