Embodiment
Embodiments providing a kind of resource regulating method and device, is same user's allocation of transmission resources in order to realize multi-cell cooperating.
Comp technology improves the signal receiving quality of subscriber equipment by the mode of multiple cell cooperative transmitting user data, reduces presence of intercell interference, thus effectively improves power system capacity and edge customer spectrum efficiency.The core realizing multiple cell cooperative transmitting user data how to allow multiple logic independently realize the centralized dispatching (or claiming cooperative scheduling) of resource in community, the embodiment of the present invention proposes a kind of resource scheduling scheme realizing multiple cell centralized dispatching, it is the transfer resource of the subscriber equipment centralized dispatching multiple cell needing multi-cell cooperating transmitting user data by a centralized dispatching device, thus realize coordinated multipoint transmission, and for not needing the user of coordinated multipoint transmission, Ze Ge community independence scheduling transmission resources, namely adopts distributed scheduling scheme.
Mode for dispatching user facility transfer resource in the embodiment of the present invention has two kinds, and one is centralized dispatching, and one is distribution schedule.So-called centralized dispatching is the transfer resource of the multiple community of same user equipment allocation (comprising home cell and another one or multiple designated cell) exactly; So-called distribution schedule, exactly for subscriber equipment only distributes the transfer resource of its home cell.
In the embodiment of the present invention, in each cell, allocate two spike-type cultivars set in advance, one is centralized dispatching resource set, is applied to the process of centralized dispatching; Another kind is distribution schedule resource set, is applied to the process of distribution schedule.Centralized dispatching resource set in each community and the distribution method of distribution schedule resource set can be identical, also can be different.
Further, according to information such as channel qualities, in advance the subscriber equipment in each community is divided into two classes, i.e. distribution schedule subscriber equipment and centralized scheduling user equipment.So-called distribution schedule subscriber equipment, namely only needs the subscriber equipment of the transfer resource taken in its home cell; So-called centralized scheduling user equipment, namely except needing to take except the transfer resource in the centralized dispatching resource set in its home cell, also to take the transfer resource in the centralized dispatching resource set in another designated cell, wherein said designated cell, the i.e. cooperation district of the home cell of this centralized scheduling user equipment, when sending signal to this centralized scheduling user equipment, take the home cell of this centralized scheduling user equipment and the transfer resource of described cooperation district simultaneously.
Preferably, distribution schedule subscriber equipment is the subscriber equipment of center of housing estate, and centralized scheduling user equipment is the subscriber equipment of cell edge.
See Fig. 1, a kind of resource regulating method that the embodiment of the present invention provides totally comprises step:
S101, determine the centralized scheduling user equipment needing the transfer resource simultaneously taking multiple community, and the centralized dispatching resource set of multiple communities corresponding to this centralized scheduling user equipment.
S102, from described centralized dispatching resource set, obtain transfer resource and distribute to described centralized scheduling user equipment.
Wherein, the centralized dispatching resource set of multiple communities that centralized scheduling user equipment is corresponding, comprises the centralized dispatching resource set of the home cell of centralized scheduling user equipment, and the centralized dispatching resource set of another one or multiple designated cell.
Preferably, step S102 comprises:
According to being the scheduling weights that each centralized scheduling user equipment is distributed in advance, dispatching priority sequence is carried out to each centralized scheduling user equipment;
According to the dispatching priority clooating sequence of each centralized scheduling user equipment, from the centralized dispatching resource set that each centralized scheduling user equipment is corresponding, obtain transfer resource and distribute to this centralized scheduling user equipment.
Preferably, from centralized dispatching resource set corresponding to each centralized scheduling user equipment, transfer resource is obtained and the step distributing to this centralized scheduling user equipment comprises:
When there is no the transfer resource that can be scheduled in the centralized dispatching resource set of designated cell corresponding to centralized scheduling user equipment, only from the centralized dispatching resource set of home cell corresponding to this centralized scheduling user equipment, obtain transfer resource and distribute to this centralized scheduling user equipment.
Preferably, the method also comprises the distribution schedule step of transfer resource:
Determine the distribution schedule subscriber equipment of the transfer resource only taking home cell, and the distribution schedule resource set of home cell corresponding to this distribution schedule subscriber equipment; From this distribution schedule resource set, obtain transfer resource and distribute to distribution schedule subscriber equipment.
During for distribution schedule dispatching user facility transfer resource, transfer resource in distribution schedule resource set in the home cell of this distribution schedule subscriber equipment of prioritizing selection, if there is no the transfer resource that can be scheduled in this distribution schedule resource set, then consider the current transfer resource be not scheduled in the centralized dispatching resource set in the home cell of this distribution schedule subscriber equipment of scheduling.
Distribution schedule can be identical with the cycle of centralized dispatching, also can be different; Come into force initial time and the effective time of distribution schedule and centralized dispatching can be identical, also can be different.
In the embodiment of the present invention, for performing the entity of centralized dispatching, it is centralized dispatching device.This centralized dispatching device obtains the centralized dispatching resource set information in multiple community in advance, and the information of centralized scheduling user equipment.
Described centralized dispatching resource set information comprises: the frequency of each community, for information such as the number of the time frequency unit of centralized dispatching and the positions of time frequency unit.
Transfer resource described in the embodiment of the present invention, specifically refers to running time-frequency resource, and running time-frequency resource take time frequency unit as Basic Transmission Unit, each time frequency unit serial number, and the position of time frequency unit can characterize by the numbering of time frequency unit.
The information of described centralized scheduling user equipment comprises: the mark (ID) of centralized scheduling user equipment, the mark (ID) of the home cell of centralized scheduling user equipment, service quality (QoS) information of customer service, the buffer data size of centralized scheduling user equipment, channel quality information, the information such as the mark (ID) of cooperation district.The cooperation district that each subscriber equipment is corresponding can have one, also can have multiple.
In the embodiment of the present invention, the home cell of centralized scheduling user equipment and cooperation district by a base station unified management, also can be managed by different base station.When the home cell of centralized scheduling user equipment and cooperation district are by a base station unified management, centralized dispatching device is positioned at this base station.When the home cell of centralized scheduling user equipment and cooperation district are managed by different base station, centralized dispatching device is positioned at one of them base station.So, the mode that centralized dispatching device obtains the centralized dispatching resource set information of multiple community and the information of centralized scheduling user equipment has two kinds:
When the home cell of centralized scheduling user equipment and cooperation district are by a base station unified management, then centralized dispatching device directly can obtain the centralized dispatching resource set information of multiple community by the mode of internal data information sharing, and the information of centralized scheduling user equipment.Such as, as shown in Figure 2, a BTS management You Sange community, and centralized dispatching device is positioned at this base station, for the Cell Edge User equipment centralized dispatching transfer resource for these three communities.
When the home cell of centralized scheduling user equipment and cooperation district are managed by different base station, as shown in Figure 3, communication interface (this interface can be X2 interface) between then needing by base station is by the centralized dispatching resource set information of multiple community, and the message notice of centralized scheduling user equipment is to the centralized dispatching device being positioned at one of them base station, concrete advice method, can be periodically notify, also can be the triggering notice of event.
Centralized dispatching device obtains the centralized dispatching resource set information of multiple community, and after the information of centralized scheduling user equipment, first according to the scheduling weights of each centralized scheduling user equipment, each centralized scheduling user equipment is sorted, such as, adoption rate justice (PF, Portion Fair) algorithm sorts.After completing sequence, centralized dispatching device putting in order according to this dispatching priority is each the centralized scheduling user equipment scheduling transmission resources in queue.
Centralized scheduling user equipment, needs to take the resource in the centralized dispatching resource set of its home cell and cooperation district simultaneously; If the resource in the centralized dispatching resource set of cooperation district is taken by other centralized scheduling user equipment, the resource in the centralized dispatching resource set of its home cell is then only distributed for centralized scheduling user equipment, the data of this centralized scheduling user equipment are only transmitted in its home cell, does not carry out the cooperative transmission of multiple cell.
In the process for centralized scheduling user equipment allocation of transmission resources, need to consider buffer memory (Buffer) the data message amount of centralized scheduling user equipment, and the attribute such as QoS.
After centralized dispatching device completes the Resourse Distribute to each centralized scheduling user equipment, schedule information corresponding for centralized scheduling user equipment is sent to the Signal transmissions entity in the home cell of this centralized scheduling user equipment.If the home cell of centralized scheduling user equipment and cooperation district are managed by different base station, then the schedule information that centralized scheduling user equipment is corresponding can be sent by the communication interface between base station equally.Wherein, the schedule information that described scheduling user's set is corresponding, comprises the information of the transfer resource for centralized scheduling user equipment distribution.
In the embodiment of the present invention when carrying out transmitting scheduling information by the communication interface between base station, further contemplate the propagation delay time of the communication interface between base station, in centralized dispatching process, the initial time that comes into force of the transfer resource be scheduled should have certain time delay.Therefore, in the embodiment of the present invention, when home cell to each centralized scheduling user equipment sends schedule information, be designated as the initial time that comes into force of the transfer resource that this centralized scheduling user equipment is distributed further, or the transfer resource delay certain hour being designated as the distribution of this centralized scheduling user equipment comes into force.
Further, in order to avoid sending schedule information too frequently, effective time of transfer resource that centralized scheduling user equipment is distributed can be designated as, minimum scheduling time unit of system can be greater than this effective time.The cycle of distribution schedule and centralized dispatching can be different, and the initial time that comes into force, the effective time of the resource of distribution schedule and the resource of centralized dispatching also can be different.
In order to improve frequency spectrum scheduling efficiency, each community is in distribution schedule process, if the information of the current occupied centralized dispatching resource of this community known, then can judge whether also to exist in the centralized dispatching resource set arranged as this community in advance remaining can occupied transfer resource, if existed, then in distribution schedule process, also can by this fractional transmission Resourse Distribute to distribution schedule subscriber equipment.
The Signal transmissions entity of the responsible signal transmission that each logic district is corresponding, after the schedule information obtaining the transmission of centralized dispatching device, determine the transfer resource of centralized scheduling user equipment and correspondence thereof, and the coming into force initial time and effective time of this transfer resource, and when the initial time that comes into force arrives, in effective time section, distributed transfer resource can be adopted to send signal to the centralized scheduling user equipment of correspondence.
Provide the concrete example explanation of centralized dispatching between centralized dispatching and base station in base station below respectively.
Such as, in time division duplex (LTE-TDD) system of the Long Term Evolution of 10MHz bandwidth, have 3 neighbor cells, these 3 neighbor cells are by the control and management of same base station, and centralized dispatching device is positioned at this base station.
Suppose that the transfer resource of each community is divided into 50 basic scheduling units (being called PRB) in frequency, respectively 10 PRBs of the numbering of each community from 1 to 10 are used for centralized dispatching, i.e. PRB1-10, the cycle of centralized dispatching and distribution schedule is all 1 millisecond (ms), time of delay of coming into force is all 1ms, is described for descending centralized dispatching.
Suppose user device set in community 1 for UE11, UE12, UE13}, the weights of dispatching priority are that { P11, P12, P13}, namely dispatch according to the order of UE11, UE12, UE13 successively; Cooperation district is that { 3 ,-1 ,-1}, wherein, 3 represent that cooperation districts are that community 3 ,-1 represents to there is not cooperation district, and namely UE11 is centralized scheduling user equipment, and its cooperation district is community 3, UE12 and UE13 is distribution schedule subscriber equipment; Schedulable PRB number is 50, is respectively PRB1,1, PRB1,2, PRB1,3......PRB1,50; Wherein, the number at most for the PRB of centralized dispatching is 10, is respectively PRB1,1 to PRB1,10.
Suppose user device set in community 2 for UE21, UE22, UE23}, and the weights of dispatching priority be P21, P22, P23}, cooperation district is {-1,1 ,-1}; UE22 is centralized scheduling user equipment, and its cooperation district is community 1.The number of schedulable PRB is 50, is respectively PRB2,1, PRB2,2, PRB2,3......PRB2,50, and wherein, the number at most for the PRB of centralized dispatching is 10, is respectively PRB2,1 to PRB2,10.
Suppose user device set in community 3 for UE31, UE32, UE33}, corresponding scheduling weights are { P31, P32, P33}; Corresponding cooperation district is {-1 ,-1,2}; UE33 is centralized scheduling user equipment, and its cooperation district is community 2.The number of schedulable PRB is 50, is respectively PRB3,1, PRB3,2, PRB3,3......PRB3,50, and wherein, the number at most for the PRB of centralized dispatching is 10, is respectively PRB3,1 to PRB3,10.
First, the distribution schedule of each community is performed:
Community 1: distribution schedule subscriber equipment is that { UE12, UE13}, the weights of dispatching priority are that { P12, P13}, available resources are PRB1,11-50.
Community 2: distribution schedule subscriber equipment is that { UE21, UE23}, the weights of dispatching priority are that { P21, P23}, available resources are PRB2,11-50.
Community 3: distribution schedule subscriber equipment is that { UE31, UE32}, the weights of dispatching priority are that { P31, P32}, available resources are PRB3,11-50.
In each community, the weights according to the dispatching priority of this community distribution schedule subscriber equipment carry out prioritization, then according to the transfer resource that the assignment profile scheduling resource that puts in order is concentrated, suppose that scheduling result is as follows:
Community 1:UE12 takies the PRB1 of this community, 11-40; UE13 takies the PRB1 of this community, 41-50.
Community 2:UE21 takies the PRB1 of this community, 11-50.
Community 3:UE32 takies the PRB1 of this community, 11-30; UE31 takies the PRB1 of this community, 31-50.
Suppose that the initial time that comes into force of the resource being distributed scheduling is the initial time of distribution schedule next time, dispatching cycle is 1ms.
Centralized dispatching device, by the data-interface of inside of base station, obtains the centralized dispatching resource set information of these 3 communities and the information of centralized scheduling user equipment.Also the information dynamic data base of these 3 communities can directly be read to obtain these information.Wherein, the information spinner of centralized scheduling user equipment will comprise: the ID of centralized scheduling user equipment in the 1-3 of community, scheduling weights P, the ID of home cell, the ID of cooperation district, and data to be transmitted amount T.Centralized dispatching resource set information comprises: each community can be used for the total N of the PRB of centralized dispatching and corresponding numbering (Index).
Centralized dispatching device is according to the order from big to small of dispatching priority weights P corresponding to the centralized scheduling user equipment of each community, each centralized scheduling user equipment is sorted, and is followed successively by each centralized scheduling user equipment scheduling transmission resources by ranking results.
Such as, ranking results is: { UE11, UE33, first UE22}, then dispatch UE11, and its home cell is community 1, cooperation district is community 3, the resource then taking community 1 is PRB1,1-8, and the resource simultaneously taking community 3 is PRB3,1-8, certainly for the resource of UE11 scheduling also can be PRB1,1-10 and PRB3,1-10.Then dispatch UE33, its home cell is community 3, and cooperation district is community 2, but the PRB3 in the centralized dispatching resource set of community 3,1-8 is taken by UE11, so this resource for UE33 scheduling is the PRB3 in community 3, PRB2 in 9-10 and community 2,9-10.Finally dispatch UE22, its home cell is community 2, and cooperation district is community 1, but the PRB2 in community 2,9-10 is taken by UE33, and the PRB1 of community 1,1-8 resource is taken by UE11, so this cannot call PRB2 for UE22, the resource of 9-10, and PRB1, the resource of 1-8, that is UE22 this cannot obtain the resource of centralized dispatching, the resource PRB2 of its home cell can only be taken, 1-8.
It should be noted that, the frequency that the PRB for multiple communities of same dispatching user facility is corresponding must be identical, and such as, the resource that UE11 takies community 1 is PRB1,1-8, then the resource taking community 3 is PRB3,1-8, and can not be PRB3,9-10.
So far, the Resourse Distribute of all centralized scheduling user equipment completes, and now surplus resources PRB1 is gone back in community 1,9-10.
The result of dispatching above is passed to the entity being responsible for Signal transmissions in community 1, community 2 and community 3 by internal interface, the initial time that comes into force simultaneously being designated as the resource that centralized scheduling user equipment is distributed is the initial time in next centralized dispatching cycle, for the effective time of the resource of centralized scheduling user equipment distribution is 1ms.
After the Signal transmissions entity of each community obtains the schedule information of centralized scheduling user equipment, at the initial time in next centralized dispatching cycle, for centralized scheduling user equipment sends downstream signal on corresponding PRB, after completing transmission, the information of each cell update centralized scheduling user equipment, and centralized dispatching resource set information.When centralized dispatching device carries out centralized dispatching again, utilize the information of the centralized scheduling user equipment after upgrading, call the resource in new centralized dispatching resource set.
When centralized dispatching device be arranged in three communities be in charge of the base station of a community time, such as, centralized dispatching device is arranged in the base station being in charge of community 2, and community 1 and community 3 are respectively by different BTS managements, now, centralized dispatching device, by the internal data interface of the base station at self place, obtains information and the centralized dispatching resource set information of the centralized scheduling user equipment of community 2.In realization, also directly can read the information dynamic data base of community 2 to obtain these information.Further, centralized dispatching device, by the X2 interface between base station, obtains information and the centralized dispatching resource set information of the centralized scheduling user equipment of community 1 and community 3.After having dispatched, schedule information by internal interface, is passed to the Signal transmissions entity in community 2 by centralized dispatching device, and schedule information is informed to the Signal transmissions entity in community 1 and community 3 by the X2 interface between base station.
After each community obtains schedule information, in next distribution schedule cycle, for distribution schedule subscriber equipment sends downstream signal on corresponding PRB.Suppose that the cycle of centralized dispatching is greater than the cycle of distribution schedule, such as 2 all after dates of the resource of current centralized dispatching after current scheduling completes just work, so in the time period of ensuing 3-10ms, distribution schedule subscriber equipment can use the no resource of centralized dispatching, such as from the 5ms of 11-15ms, in community 1, in centralized dispatching resource set, remaining transfer resource is PRB1,9-10, therefore, this part resource can be dispatched during distribution schedule.
After cycle of distribution schedule reaches, the information of renewal distribution scheduling user's set and the information of distribution schedule resource set, when distribution schedule device corresponding to each community carries out distribution schedule again to this local resource, utilize the information of the distribution schedule subscriber equipment after upgrading, call the resource in new distribution schedule resource set.
