Fig. 4 shows the schematic diagram of wireless telecommunication system configuration according to another embodiment of the present invention.In this embodiment, for convenience of description, show device for mobile communication with user's device one vocabulary, and show with millimicro cellular base stations one vocabulary and to carry out millimicro cellular base stations or millimicro cellular base stations.As shown in Figure 4, wireless telecommunication system comprises 3 millimicro cellular base stations 410,420 and 430, millimicro cellular base stations 410 comprises user's device 412,414,416 respectively, millimicro cellular base stations 420 comprises user's device 422,424,426 respectively, and millimicro cellular base stations 430 comprises user's device 432,434,436 respectively.When initial, the user device of the original group member of each millimicro cellular base stations for itself serving, so the g of group of millimicro cellular base stations 410 correspondences 410The member be { 412,414,416}, the g of group of millimicro cellular base stations 420 correspondences 420The member be { 422,424,426}, and the g of group of millimicro cellular base stations 430 correspondences 430The member be { 432,434,446}.In this embodiment, as shown in Figure 4, user's device 412 is the covering scopes that are positioned at millimicro cellular base stations 410,420 and 430 overlapping, user's device 422 is the covering scopes that are positioned at the overlapping of millimicro cellular base stations 410 and 420, and user's device 434 is the covering scopes that are positioned at the overlapping of millimicro cellular base stations 410 and 430.Because user's device 412 is in the covering scope of millimicro cellular base stations 420 and 430, therefore be subjected to the serious interference of millimicro cellular base stations 420 and 430, so user's device 412 is added to the g of group of millimicro cellular base stations 420 and 430 respectively 420With g 430In.Similarly, user's device 422 is in the covering scope of millimicro cellular base stations 410 with user's device 434, therefore is subjected to the serious interference of millimicro cellular base stations 410, so user's device 422 and 434 is added to the g of group of millimicro cellular base stations 410 410In.User's device 412 is the covering scopes that are positioned at millimicro cellular base stations 430, therefore is subjected to the serious interference of millimicro cellular base stations 430, so user's device 412 is added to the g of group of millimicro cellular base stations 430 430In.Therefore, after the information of upgrading neighbor base station, the g of group of millimicro cellular base stations 410 correspondences 410The member become { 412,414,416,422,434}, the g of group of millimicro cellular base stations 420 correspondences 420The member become { 412,422,424,426}, and the g of group of millimicro cellular base stations 430 correspondences 430The member become { 412,432,434,446}.Wherein, because of the g of group 410With g 430Comprise user's device 434 simultaneously, therefore, when disposing the resource of user's device 434, must be configured simultaneously by millimicro cellular base stations 410 and 430, the expression g of group 410With g 430To form a distribution group.Similarly, because of the g of group 410With g 420Comprise user's device 422 simultaneously, therefore, when disposing the resource of user's device 422, must be configured the expression g of group by millimicro cellular base stations 410 and 420 cooperations 410With g 420To form a distribution group; In like manner, because of the g of group 410, g 420, g 430Comprise user's device 412 simultaneously, therefore, when disposing the resource of user's device 412, must be configured the expression g of group by millimicro cellular base stations 410,420 and 430 cooperations 410, g 420With g 430To form a distribution group.
Get back to Fig. 2, because device for mobile communication 310 is the wherein member in the group of evolution millimicro cellular base stations 110 and 210 simultaneously, therefore, evolution millimicro cellular base stations 110 and 210 must cooperation ground Resources allocation be given device for mobile communication 310.Similarly, because device for mobile communication 320 is the wherein member in the group of evolution millimicro cellular base stations 210 and 110 simultaneously, therefore, evolution millimicro cellular base stations 210 and 110 also must cooperation ground Resources allocation be given device for mobile communication 320.
So, evolution millimicro cellular base stations 110 and 210 then carries out group's cooperation formula resource and distributes (step S218), available resources cooperation ground according to evolution millimicro cellular base stations 110 and 210 carries out resource distribution to device for mobile communication 310 and 320, and after configuration is finished, respectively resource allocation result is given device for mobile communication 310 and device for mobile communication 320 (step S220, S222).Detailed group's cooperation formula resource allocation step will be illustrated in down.
In this embodiment, group's cooperation formula resource allocation methods is to be that unit carries out the resource distribution and each group can carry out resource and distribute voluntarily subsequently according to group size around detected with the group, and the resource distribution result is transferred to group updating on every side again.Wherein, the order that determines group allocation be with maximum on every side group (that is: the group with group member quantity of local maximum) begin, this principle can make that the resource usage degree reaches the highest in the zone in advance.In addition, the principle that resource is distributed has higher priority with the user's device that does not satisfy minimum transmission conditions as yet, unnecessary resource is carried out additional allocation again, and if when the resource that can use satisfies user's need for equipment in the group inadequately, millimicro cellular base stations under this group can allow to require millimicro cellular base stations around it to abandon using to have distributed but be not resource for the minimum resources demand condition that satisfies its member (UE), then distribute to user's device in this group, to satisfy its minimum resources demand condition.Afterwards, after maximum on every side group's resource assigns, other still unappropriated group carry out resource in regular turn according to above-mentioned principle again and distribute.
Each group the inside needs to note two things.At first, when supposing that other contiguous millimicro cellular base stations has kept certain a resource to a user, then this millimicro cellular base stations also will keep this part resource to this user, is repeated to use to avoid resource, interrupts probability (outage rate) thereby reduce to use.Secondly, in order to make system transmissions flow (system throughput) that good performance also can be arranged, in some embodiment, resource allocation methods of the present invention is further resource to be assigned as the main resource (primary resource) of the necessary resource of expression and the less important resource (secondary resource) of representing the inessential resource of additional allocation.Specifically, main resource is the resource distribution that meets the minimum resources demand of each user's device, and less important resource has then disposed the resource remaining available resource afterwards that meets its minimum resources demand for all user's devices.For instance, the minimum resources demand of supposing user's device is two resource block (resource block, RB), and this UE can use three resource block RB1, RB2, RB3 after the resource distribution, then wherein two resource block RB1, RB2 will be denoted as main resource, and another resource block RB3 will be denoted as less important resource, and this extra resource is used to provide better usefulness.When supposing to have any one millimicro cellular base stations to find oneself not had enough resources to the user's device in its group, this millimicro cellular base stations can be from originally designated, but the resource block (example is resource block RB3 as in the previous example) that belongs in the less important resource requires to be used as its main resource, to satisfy the minimum resource requirements of its group's the inside user's device.
Specifically, group of the present invention cooperation formula resource allocation methods can more be subdivided into three steps, is respectively initialization step, measuring process and resource distribution step.At first, in each resource allocation cycle, all millimicro cellular base stations and user's device thereof are carried out initialization step, begin to carry out initialization.Then, in measuring process, the received signal-to-jamming ratio of all user's measurement devices example is also upgraded the signal-to-jamming ratio example that measures and is given contiguous millimicro cellular base stations, sets up cooperative relationship with the millimicro cellular base stations of relevant vicinity.Can form a plurality of groups according to the information that comprises the signal-to-jamming ratio example of renewal, afterwards, can group be that unit carries out resource distribution just.
For instance, in an embodiment, suppose total K millimicro cellular base stations in the service network, each millimicro cellular base stations comprises M device for mobile communication or the user's device (UE) in the service, and always has N available resource block.Then initialized step will be set up following set, it comprises that resource block set R, a user (for example: minimum quality of service (Quality of services, QoS) demand) set Q and resource requirement set D gather U, a millimicro cellular base stations set F, a cooperation formula cluster set G, a minimum resources demand.Resource block set R is expressed as R 1xN={ r 1..., r N, r wherein nRepresent n resource block.The user gathers U, is expressed as U KxM={ u 1,1..., u 1, M, u 2,1..., u K, M, u wherein K, mM the UE that represents k millimicro cellular base stations.u K, mIn content for distributing to u K, mResource block.For instance, u K, m={ r 2, r 3In order to represent u K, mCan use resource block r 2With r 3Millimicro cellular base stations set F is expressed as F 1xK={ f 1..., f K, f wherein kThe subclass of representing k millimicro cellular base stations.For instance, f 1The subclass of representing the 1st millimicro cellular base stations.Subclass f kIn content for distributing to f kResource block.For instance, f k={ r 2, r 3In order to represent f kCluster set g kIn UE all can use resource block r 2With r 3Cluster set g kTo be discussed at down.
Cooperation formula cluster set G is expressed as G 1xK={ g 1..., g K, g wherein kExpression is subjected to f kThe set that all UE of influence form.When initial, g k={ u K, 1..., u K, M.Subclass g among the G kIn order to represent f kNeed cooperation ground Resources allocation to give which UE.In other words, g kIn content be other millimicro cellular base stations when preparing to want allocated resource to wherein any UE, f kNeed with the UE of other millimicro cellular base stations collaboration process.For instance, suppose millimicro cellular base stations f 1Corresponding cluster set g 1Comprise millimicro cellular base stations f 2User's device u 2,1The time, then as millimicro cellular base stations f 2Prepare to want allocated resource to user's device u 2,1The time, millimicro cellular base stations f 1Just need and millimicro cellular base stations f 2Coact to handle user's device u 2,1Resource distribute.
Minimum resources requirements set Q is expressed as Q KxM={ q 1,1..., q 1, M, q 2,1..., q K, M, q wherein K, mRepresent m user's of k millimicro cellular base stations minimum QoS resource requirement.For instance, q K, m={ 2} is in order to represent u K, m2 resource block of minimum needs.Resource requirement set D is expressed as D KxM={ d 1,1..., d 1, M, d 2,1..., d K, M, d wherein K, mM UE resource needed quantity representing k millimicro cellular base stations.For instance, d K, m={ 2} is in order to represent u K, mNeed 2 channel resource blocks.
In some embodiment, can use a threshold value to come the basis for estimation of Resources allocation as whether, but the present invention is not limited to this with needing cooperation.For instance, threshold value can decide according to a service quality (QoS) scope of calculating, but the invention is not restricted to this.When a certain specific user's device is lower than threshold value by the measured signal-to-jamming ratio example of its contiguous millimicro cellular base stations, represent that it is subjected to this contiguous millimicro cellular base stations and seriously disturbs, and therefore just adds the subclass g of contiguous millimicro cellular base stations so far with this specific user's device kIn.That is to say, as user's device u K, mMeasured millimicro cellular base stations f kTo millimicro cellular base stations f K 'Signal-to-jamming ratio example when being lower than threshold value, when carrying out resource distribution, millimicro cellular base stations f K 'Must be with user u K, mList consideration jointly in.It is to be configured the channel resource to its UE that serves for the millimicro cellular base stations configuration that prevents from serving is same as the contiguous millimicro cellular base stations contiguous millimicro cellular base stations of its interactive interference (particularly with) that group-wise resource of the present invention is distributed.Suppose millimicro cellular base stations f kIn user u K, mMeasure its contiguous millimicro cellular base stations f K 'Signal-to-jamming ratio example when being lower than a threshold value, u then K, mMust be injected towards f K 'Group in, become f K 'A member in the corresponding group.
Fig. 5 assists to carry out the method flow diagram that resource is distributed required signal measurement according to the embodiment of Fig. 1 is described by user's device (UE).
As step S502, each UE corresponding one measures request, measure the signal-to-jamming ratio example of the millimicro cellular base stations of its service millimicro cellular base stations and vicinity, and basis signal interference ratio measurement result, link foundation (link creation) by its millimicro cellular base stations of serving millimicro cellular base stations and particular ambient vicinity.That is to say that UE disturbs the ratio measurement result with basis signal, send to the millimicro cellular base stations of the vicinity of disturbing and link request, add with request in the group of these contiguous millimicro cellular base stations.After linking foundation, as step S504, UE carries out channel quality assessment, and as step S506, according to the channel quality assessment result, estimates required resources requirement.For instance, UEu K, mCan carry out channel quality assessment obtains all and comprises u K, mThe present resource configuration state of the corresponding millimicro cellular base stations of group, and according to obtained present resource configuration state with and minimum resources require q K, mCalculate required requested resource demand d K, mAfter calculating required requested resource demand, as step S508, UE will comprise the information updating of the resource requirement demand that estimates to its serving BS.
When service millimicro cellular base stations receives the required requested resource demand d that calculates that descends all UE from it K, mLastest imformation after, the resources requirement that utilizes each UE to estimate carries out group's cooperation formula resource distribution of this case, afterwards, again the resource distribution result is returned to UE and is updated to other contiguous millimicro cellular base stations.So UE will be according to the resource distribution result, carry out communication with resource block and the millimicro cellular base stations of appointment.In some embodiment, UE can transmit these information that measure simultaneously and give service millimicro cellular base stations and the millimicro cellular base stations that is disturbed.
After initialization and measuring process are finished, all subclass g kThe information of user in its contiguous millimicro cellular base stations will intactly be upgraded.Suppose u K, mBe g simultaneously kWith g K 'In a wherein member time, then millimicro cellular base stations k and k ' must cooperation the ground configurating channel give user u K, mIn group of the present invention cooperation formula resource allocation methods, will be from cluster set g kAround have local maximum cluster group membership's quantity in the millimicro cellular base stations group begin configuration.
In some embodiment, aforesaid group cooperation formula resource allocation methods can carry out according to following steps: (1) sets up a set W earlier, and it comprises all groups with local maximum cluster group membership's quantity; (2) to each g of group among the W k, according to set f k' present inking device state, q is satisfied in configuration K, mThe r of number nGive g kIn user u K, m, wherein gather f K 'For comprising u K, mArbitrary g K 'Corresponding millimicro cellular base stations.When there not being enough remaining available resource r nCan support q K, mThe time, dispose the less important resource r of appointment randomly n, up to satisfying q K, mPerhaps without any less important resource r nTill.Simultaneously, with the r that has disposed nBe made as 1; (3) to each g of group among the W K 'According to set f K 'Present configuration status, dispose R fifty-fifty 1xNMiddle remaining available resource r nGive g kIn user u K, m, simultaneously, with the r that has disposed nBe made as 0; And (4) carry out the information updating step: to any g that is assigned to kIn user u K, mResource r n, u K, m← u K, m∪ { r n, f k← f k∪ { r n, g K '← g K '/ { u K, m}
Fig. 6 assists to carry out the method flow diagram that resource is distributed according to the embodiment of Fig. 1 is described by the millimicro cellular base stations.As step S602, the collect information sent from each UE of millimicro cellular base stations.Then, as step S604, the millimicro cellular base stations is according to the signal-to-jamming ratio example measurement result of the UE of contiguous millimicro cellular base stations, upgrades and determines its group member.In some embodiment, the signal-to-jamming ratio of a UE of contiguous millimicro cellular base stations example measurement result can be sent or directly be sent from this UE by the millimicro cellular base stations of this UE.For instance, to millimicro cellular base stations f k, if any contiguous millimicro cellular base stations f is arranged K 'User's device u K ', mMeasurement report point out the millimicro cellular base stations f that it measures K 'To millimicro cellular base stations f kSignal-to-jamming ratio example when being lower than threshold value, expressing possibility is subjected to millimicro cellular base stations f kThe serious interference is therefore just with this user's device u K ', mBe added to millimicro cellular base stations f kThe g of group kIn.That is to say, when carrying out resource distribution, millimicro cellular base stations f kMust be with user u K ', mList consideration jointly in.Therefore, step S604 can be subjected to all millimicro cellular base stations f kThe UE that disturbs is added to the g of its group kIn.After determining group member, as step S606, the millimicro cellular base stations distributes according to group of the present invention cooperation formula resource and specific configuration sequence, begins to carry out the group-wise resource and distributes.As described above, it is to decide configuration sequence according to the detected size of group on every side that the millimicro cellular base stations carries out the resource distribution according to specific configuration sequence, with cluster set g kAround have local maximum cluster group membership's quantity in the millimicro cellular base stations group preferentially begin configuration, the group with local time multigroup group membership quantity takes second place, the rest may be inferred.All groups according to this specific configuration sequence in regular turn to its member (that is: user's device) carry out resource and distribute.What need prompting is, if a certain millimicro cellular base stations finds that it is not the group with local maximum cluster group membership's quantity, just wait for a period of time, other group on every side with more group member quantity has all finished after the resource distribution by the time, carries out resource distribution again.In addition, in this step, the millimicro cellular base stations is configured and disposes equably remaining available resource with available resources and gives all users (as step S608) according to the minimum resources demand.Clearer and more definite, the millimicro cellular base stations will dispose the resource of the minimum resources demand of all UE that satisfy in its group and give each UE.When the resource that disposes as all UE all satisfied the minimum resources demand and the residue available channel resources is still arranged, the millimicro cellular base stations disposed the residue available channel resources equably and gives all users.Wherein, be called main resource (primary resource) again in order to the resource that satisfies the minimum resources demand, and remaining available resource is called less important resource (secondary resource).In addition, the principle that resource is distributed has higher priority with the UE that does not satisfy minimum transmission conditions as yet, unnecessary resource is carried out additional allocation again, and if when the resource that can use satisfies UE demand in the group inadequately, the affiliated millimicro cellular base stations of this group can allow to require its on every side the millimicro cellular base stations abandon use distributed but be not resource for the minimum resources demand condition that satisfies its member (user's device) (that is: the r that has been configured n=0 less important resource), then the UE that distributes in this group uses, to satisfy its minimum resources demand condition.At last, as step S610, the millimicro cellular base stations indicates each UE to use those resources to carry out communication the information updating of configuration result each UE to its group, simultaneously, with the information updating of configuration result to contiguous millimicro cellular base stations.And other does not finish the group of millimicro cellular base stations of the vicinity of distribution as yet, just can carry out follow-up resource in regular turn according to above-mentioned principle and distribute with reference to the configuration result of this millimicro cellular base stations.
Because it is to be unit with the UE in the group of millimicro cellular base stations that aforesaid resource is distributed, but not be unit with its UE that is served, and the UE in the group may stride the contiguous millimicro cellular base stations of a plurality of interactive interference, the resource allocation that can guarantee to be attached to simultaneously those UE of more than one millimicro cellular base stations can not be repeated to use, and the resource allocation of the UE in the non-zone that overlaps in the reusable contiguous millimicro cellular base stations, interruption probability capable of reducing using also obtains better system data flow.Though do not illustrate in the drawings, but evolution millimicro cellular base stations 110,210 can comprise a wireless module separately, in order to carrying out the function of wireless transmission and reception, and comprise a control module, in order to handle the above-mentioned resource allocation methods that carries out of being assisted by the millimicro cellular base stations.
What need prompting is that in previous embodiment, the arbitration that group's cooperation formula resource is distributed can be undertaken by millimicro cellular base stations oneself, need not just can realize by another central control system.In other embodiment, all base station from home can more be connected to for example self-organizing network of LTE (Self Organizing Networks of a control node, SON) control of one on node, and group's cooperation formula resource distribution also can be carried out the arbitration of group and resource distribution by the unified repayment of millimicro cellular base stations to this control node by the control node.

Fig. 8 A and Fig. 8 B are the information sequence figure according to an embodiment of the described group-wise resource distribution of the wireless telecommunication system of Fig. 7.In present embodiment, suppose that each millimicro cellular base stations comprises the group of a correspondence, wherein, the member of group is subjected to all user's devices that the affiliated millimicro cellular base stations of this group disturbs.User's device that initial group member is served for each millimicro cellular base stations itself.As shown in Figure 7, device for mobile communication 310 and device for mobile communication 320 are positioned at the covering scope of evolution millimicro cellular base stations 110,210 simultaneously, therefore, device for mobile communication 310 and device for mobile communication 320 can receive the signal of self-evolution millimicro cellular base stations 110 and 210 simultaneously.Device for mobile communication 310 at first is connected to control node 700 by evolution millimicro cellular base stations 110, after a while, device for mobile communication 310 receives from the measurement request (step S802) of controlling node 700 by evolution millimicro cellular base stations 110, in the request of measuring, indicated and to have carried out a group-wise resource distribution, therefore need carry out signal strength measurement to specific adjacent network node.When receiving the measurement request, controller module 314 require wireless module 312 detect evolution millimicro cellular base stations 110 with and the signal strength signal intensity of contiguous evolution millimicro cellular base stations 210, and according to the signal strength signal intensity that measures, obtain evolving millimicro cellular base stations 110 with and the signal-to-jamming ratio example (step S806) of contiguous evolution millimicro cellular base stations 210.After measuring end, controller module 314 sends the signal-to-jamming ratio example that measures to evolution millimicro cellular base stations 110 (step S808) by a measurement report by wireless module 312.Obtain after the measurement report from device for mobile communication 310, evolution millimicro cellular base stations 110 transfers to control node 700 (step S810) with measurement report.Since measurement report indicated evolution millimicro cellular base stations 110 with and the signal-to-jamming ratio example of contiguous evolution millimicro cellular base stations 210 less than a set threshold value, expression device for mobile communication 310 has the serious interference of the millimicro cellular base stations 210 that is subjected to evolving, therefore, must notify evolution millimicro cellular base stations 210 that device for mobile communication 310 is included in its group.So, the signal-to-jamming ratio example that control node 700 is repaid corresponding to device for mobile communication 310 is less than threshold value, transmit group update request notice evolution millimicro cellular base stations 210, request evolution millimicro cellular base stations 210 is incorporated as its group member (step S816, S820) with device for mobile communication 310.After evolution millimicro cellular base stations 210 is received from the control signal of controlling node 700, just device for mobile communication 310 is included in its group, therefore, the group of evolution millimicro cellular base stations 210 will comprise device for mobile communication 310.Similarly, device for mobile communication 320 at first is connected to control node 700 by evolution millimicro cellular base stations 110, after a while, device for mobile communication 320 receives from the measurement request (step S804) of controlling node 700 by evolution millimicro cellular base stations 210, and specific adjacent network node is carried out signal strength measurement.When receiving the measurement request, controller module 324 require wireless module 322 detect evolution millimicro cellular base stations 210 with and the signal strength signal intensity of contiguous evolution millimicro
