Embodiment

Technical scheme provided by the present invention finally solves descending interfere information and obtains insufficient situation, makes new UE more accurate to the assessment of descending interference when Target cell Resources allocation, thus reduces interference, promotes quality of service.Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.

In implementation, owing to carrying out Resourse Distribute for Target cell, so application Zhong Zhe community refers to Target cell; Meanwhile, in implementation variable all in units of dBm actual value.

First the sortord of slot priorities is described, then the determination of slot priorities is described, finally to how determining that the community of carrying out interference coordination is described.

One, the sortord of slot priorities.

Fig. 1 carries out by the sequence of slot priorities the method implementing procedure schematic diagram that accesses, as shown in the figure, can comprise the steps:

Step 101, in the queue of current SDCA slot priorities, shielding TCP interference value is greater than the DL time slot of thresholding;

Step 102, according to shielding after the list of SDCA slot priorities access;

Step 103, reduction of speed is carried out to the UE of access failure;

If still with regard to access failure after step 104 reduction of speed, after all UL, DL time slots are all obtained slot priorities list according to the sequence of SDCA time slot queuing strategy, access.

All UL, DL time slots refer to is deleting those time slots that DL time slot that TCP interference value is greater than thresholding deletes at interior all time slots.

In enforcement, when carrying out carrier wave/time slot sequence to Target cell, receiving, SDCA (the Slow Dynamic Channel Allocation of Target cell, slow dynamic channel allocation) carrier frequencies method acquiescence adopts NodeB public-measurement, DL (Down Link, down link) time slot queuing strategy acquiescence employing NodeB public-measurement, UL (Up Link, up link) time slot queuing strategy does not require the method still adopting community originally to configure here.When DL adopts TCP to measure, can with reference to the P obtained in following formula _{j, h}enforcement.In enforcement, the SDCA adopted is a kind of RRM (Radio Resource Management, RRM) algorithm, the mode of adjustment can according to the BRU of the business different choice of fixing queuing, fixed service (Basic Resource Unit, basic resources unit) several queueing form such as resource selection, also can control the uplink and downlink timeslot of the priority access of each carrier frequency in every community (N frequency).Then the SDCA based on public-measurement in the present embodiment.

In order to prevent certain carrier wave from both there is the maximum DL time slot of TCP, there is again the DL time slot that TCP is minimum, finally comprehensively getting off this carrier wave still by situation about coming above.Here 2 resources of taking turns are adopted to attempt:

The first round, the time slot that total interference TCP of DL time slot is more than or equal to thresholding (configurable under community) is deleted, according to above-mentioned said SDCA carrier wave/time slot queuing strategy, sorts, obtain carrier wave/slot priorities list, access.During carrier wave sequence, the total number of DL time slot needs to deduct deleted time slot.If access failure, need to attempt reduction of speed, if still just failure after reduction of speed, enter next round.

Second takes turns, and all UL, DL time slots all participate in above-mentioned said SDCA carrier wave/time slot queuing strategy, sort, obtain carrier wave/slot priorities list, access.

Further, can also take number of resources difference according to business, carrier wave priority and slot priorities can be considered simultaneously.

When after the priority weighting obtaining all uplink and downlink timeslots, carrier wave priority does not re-use the average weight sequence of all time slots, but from each carrier wave, select the uplink/downlink time slot combinations meeting resource requirement, and obtained the priority weighting of this combination by up-downgoing weighting.The up-downgoing demand of such as to be switched business is single time slot, then calculate following table according to the slot priorities factor:

Combination of resources	Priority weighting	Combination of resources	Priority weighting
				Carrier wave 1 TS1/TS3		Carrier wave 2 TS1/TS3
Carrier wave 1 TS1/TS4		Carrier wave 2 TS1/TS4
				Carrier wave 1 TS1/TS5		Carrier wave 2 TS1/TS5
Carrier wave 1 TS1/TS6		Carrier wave 2 TS1/TS6
				Carrier wave 1 TS2/TS3		Carrier wave 2 TS2/TS3
Carrier wave 1 TS2/TS4		Carrier wave 2 TS2/TS4
				Carrier wave 1 TS2/TS5		Carrier wave 2 TS2/TS5
Carrier wave 1 TS2/TS6		Carrier wave 2 TS2/TS6
				......	......	......	......

Finally, sort to the priority of all alternative resource combinations calculated, the time slot combinations of prioritizing selection the best carries out Resourse Distribute trial.

Two, to the determination of slot priorities.

Below to step 102 obtaining in slot priorities list process according to the sequence of SDCA time slot queuing strategy, determine the execution mode of slot priorities.

Fig. 2 is the defining method implementing procedure schematic diagram of slot priorities, as shown in the figure, can comprise the steps:

Step 201, obtain the TCP of each descending time slot of each interference adjacent cell;

Step 202, determine slot priorities according to TCP.

In enforcement, in step 201, the required interference adjacent cell obtaining TCP can adopt determined community of carrying out interference coordination in scheme one, so just can utilize determined community of carrying out interference coordination, determine travel through according to slot priorities queue and attempt access time institute's foundation slot priorities.But, for each interference adjacent cell, also can adopt other conventional meanses to determine, just adopt aforesaid way to determine carry out the community of interference coordination time, then can because using adjacent area that handover measurement reports, better effect can being obtained according to switching UE to reasons such as the received power differences of Zhong Ge adjacent area, interference coordination alternative cell.

In the enforcement of step 201, TCP (Transmitted carrier power, carrier transmit power) be NodeB public measured value, measure the transmitting carrier power of each time slot and report with the percents of maximum transmission power, by certain processing method, the TCP of adjacent area between RSPA (Radio network Signalling ProcessAssemble, radio network signaling disposable plates) plate can be made to obtain in the storage area of this plate neighboring BS information.When being implemented by certain processing method, such as a kind of simple processing method is, utilizes to have existed in communication mode between different signal command board in the rnc to add and transmits TCP information.

When performing step 202, determining in the enforcement of slot priorities according to TCP, embodiments provides mode below, the following describes as follows:

Mode one

In enforcement, after the TCP measured value of each descending time slot obtaining each interference adjacent area, the correction to measured value can be considered, therefore, further, can also comprise:

TCP is processed in the following manner:

α _ifor the path loss weighted value calculated by PCCPCH information;

When each community PCCPCH transmitting power is identical:

α _i=(PCCPCH_RSCP _i-PCCPCH_RSCP _t) (formula 1),

Or, when each community PCCPCH transmitting power is different:

α _i=(PCCPCH_RSCP _i-PCCPCH_Power _i)-(PCCPCH_RSCP _t-PCCPCH_Power _t) (formula 2)

I subscript represents current interfered cell, and t subscript represents Target cell, and unit is dB.

J, h represent h descending time slot of a jth carrier wave of community respectively.

α _irepresent the path loss weighting coefficient values of i-th interfered cell.

PCCPCH_Power represents the transmitting power of PCCPCH.

Concrete, for each interference adjacent area, because TCP value is the transmitting power of NodeB side, therefore a path loss weight coefficient can be considered, a switch control rule in enforcement, can be set, be decided under present case the need of this weighting by it.Weighting scheme can not enumerate, and formula 1, formula 2 are wherein two kinds of weight computing modes.Wherein, formula 1 thinks that all cell downlink maximum transmission power are identical, and formula 2 considers all cell downlink maximum transmission power may be different.

The effect of path loss weighting process is to revise the potential serious interference degree in homogeneous-frequency adjacent-domain, because TCP is the transmitting power of base station, path loss is not had to affect, therefore need to revise, in order to avoid community far away consistent with nearer community TCP, but may cause on UE the situation disturbing different impact.So in embodiment with the formula 1, formula 2 carried out implementation for example; But, in theory, also be fine by other mode, as long as can realize revising the potential interference strength this purpose in homogeneous-frequency adjacent-domain, formula 1, formula 2 are only for instructing those skilled in the art specifically how to implement the present invention, but do not mean and only can use formula 1, formula 2, in implementation process, can need in conjunction with practice the processing mode determining corresponding path loss weighting.

So, if switch opens, then TCP value in adjacent area is done and can be treated to:

if closed, then directly use current TCP value TCP ' _{i, j, h}=TCP _{i, j, h}.The meaning of its value is still percentage.

In enforcement, after the TCP measured value of each descending time slot obtaining each interference adjacent area, can consider whether Target cell is counted interference effect, therefore, further, can also comprise:

Obtain the TCP of each descending time slot of this community, and determine slot priorities according to the TCP of this community and each interference adjacent cell.

In concrete enforcement, when Target cell is counted interference effect, a switch can be simply set, in order to control whether Target cell is counted consideration, if this switch opens, the TCP of Ze Jiangzhe community includes final priority in and considers, otherwise only uses the adjacent area except Target cell to calculate.

After determine the TCP determining slot priorities according to aforesaid way, in execution step 202, can implement as follows:

$P_{j,h}=\frac{\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{\mathrm{TCP}}_{i,j,h}\×{10}^{\frac{\mathrm{MaxTrans}{\mathrm{Power}}_i+{\mathrm{\α}}_i}{10}}}{\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{10}^{\frac{\mathrm{MaxTrans}{\mathrm{Power}}_i}{10}}}$ (formula 3)

Or,

$P_{j,h}=\frac{{\mathrm{TCP}}_{t,j,h}\×{10}^{\frac{\mathrm{Max}{\mathrm{TransPower}}_t}{10}}+\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{\mathrm{TCP}}_{i,j,h}\×{10}^{\frac{M{\mathrm{axTransPower}}_i+{\mathrm{\α}}_i}{10}}}{{10}^{\frac{\mathrm{Max}{\mathrm{TransPower}}_t}{10}}+\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{10}^{\frac{{\mathrm{MaxTransPower}}_i}{10}}}$

(formula 4)

Wherein, j, h represent h descending time slot of a jth carrier wave of community respectively, and N is interference adjacent area number.

I subscript represents current interfered cell, and t is Target cell, P _{j, h}for the priority of h descending time slot of a jth carrier wave.

For TCP _{i, j, h}, in mode one, owing to directly using TCP value, therefore also can replace with TCP _{i, j, h}; Also namely, if switch opens, then TCP value in adjacent area does following process:

if closed, then directly use current TCP value TCP ' _{i, j, h}=TCP _{i, j, h}.The meaning of its value is still percentage.

The reason illustrated is, in following mode two, owing to changing computational methods, so TCP has been with subscript, to show the difference with mode one;

MaxTransPower _ishi Gai community maximum transmission power, it is the important parameter of RNC, generally all can see this parameter by Operation and Maintenance interface, also namely can know this parameter by RNC.

In concrete enforcement, when calculating slot priorities, according to the measured value of acquisition and the control of two switches, can add up total interference value to h descending time slot of the jth of a Target cell carrier wave, N is interference adjacent area number; Like this at use TCP measured value, through the control of two switches, and the consideration of path loss weighting, finally obtain slot priorities, because concrete account form is a lot, as long as total the mode that can count the interference value of a time slot can adopt, can not enumerate here, in above-mentioned two kinds of modes, formula 3 describes a kind of priority account form not considering Target cell TCP; Formula 4 describes a kind of priority account form considering Target cell TCP.

Mode two

Each carrier wave of each community under current RNC, descending time slot TCP cycle are being upgraded, during in order to interference coordination reference, because TCP is NodeB public measured value, and the different UE in multiple position may be there is in this descending time slot, these UE are different from the current position relation switching UE, and the interference caused is not identical yet.Therefore, further, can also implement as follows to reach descending interference assessment more accurately.

1, AOA (the Angel Of Arrival of user of each carrier wave in all communities under current RNC, each time slot is obtained, angle of arrival) and TCP special measurement information, in concrete enforcement, these parameters also can by being configured to NodeB periodic report or reporting events obtains;

2, the PCCPCH_RSCP information of all connection UE under obtaining current RNC, in concrete enforcement, these parameters also can by being configured to UE periodic report or reporting events; Reporting schemes can comprise:

1), all UE periodic report pilot measurements are configured.

2), introduce new event definition, all trigger UE when meeting entry condition or meeting and leave condition and report measurement report.Cai the measurement report of general switching is the reporting measurement reports when meeting entry condition only, in order to the measurement report supporting interference coordination to need, adding and also triggering UE reporting measurement reports when meeting and leaving condition.Whether meet leave condition time reporting measurement reports can be controlled by a parameter ReportOnLeave.Specifically can with reference to the A3 event implementation in TS36.331.

In enforcement, according to the AOA of the user of each carrier wave, each time slot, can correct by the interference of GOB directional diagram to each time slot.

The meaning corrected is tabled look-up on GOB directional diagram in user AOA direction, and obtain the upwards possible figuration gain of actual the party, with later to the weighting of transmitting power, to embody the effect of intelligent antenna figuration.

Carry out angular divisions to the AOA according to each reporting of user below, the enforcement calculating descending interference is more accurately described.

For every time slot single user, directly by TCP stored in the corresponding list cell in maximum direction.

For the situation of every time slot multi-user, need to calculate respectively, a more comprehensive maximum direction unit stored in.Computational methods are as follows:

GOB (the Grid Of Beam of the coupling antenna type of preservation different districts, RNC side, beam scanning method) directional diagram, according to the estimation of AOA, in directional diagram with AOA direction for maximum, and with the angle of figuration direction maximum within a thresholding (such as 3dB), confirm its position in the following table.For multi-user, need by the directional diagram of multiple user superpose, and consider with the angle of figuration direction maximum in a threshold range, respectively stored in.

For aforesaid way, only save the angle interference in maximum direction, do not think over the impact of secondary lobe, can by consider more carefully by every user side of completing to superposition stored in, superpose at next step, to obtain better effect.Due to the inaccuracy that directional diagram is estimated, here may be more effective for larger differential seat angle.

RNC side periodic maintenance one can consider the interference reference quantity in direction, can pass through a switch here, considers the interference assessment of carrying out different accuracy.When the switch is closed, consider a kind of assessment roughly, choose a kind of periodic maintenance as following table namely to each community, can select any spacing for angular range, only example is wherein a kind of below:

For certain carrier wave, for certain sector, every 10 degree of reservations one value, TCP ' represents the slot transmission power after weighted direction

During for switch opens, according to the PCCPCH_RSCP of every user's periodic report above, the path loss that can obtain every user is:

PathLoss=PCCPCH_Power-PCCPCH_RSCP (formula 5)

Then after the path loss obtaining each UE, approximate calculation can go out current area each descending time slot of certain carrier wave to the interference of other community, for numerous method, only list two kinds here:

For K user of a jth carrier wave h descending time slot, consider that it takies the impact of resource and path loss:

${{\mathrm{TCP}}^{\′}}_{j,k,h}=\underset{k=1}{\overset{K}{\mathrm{\Σ}}}({\mathrm{TCP}}_{j,k,h}/{\mathrm{BRU}\_\mathrm{NUM}}_k-{\mathrm{PathLoss}}_{i,k})$ (formula 6)

BRU_NUM _krefer to BRU (Basic Resource Unit, the basic resources unit) number shared by a kth user.

For K user of a jth carrier wave h descending time slot, consider that it takies the impact of resource and path loss and AOA:

${{\mathrm{TCP}}^{\′}}_{j,k,h,\mathrm{AOA}}=\underset{k=1}{\overset{K}{\mathrm{\Σ}}}({\mathrm{TCP}}_{j,k,h}/{\mathrm{BRU}\_\mathrm{NUM}}_k\×\mathrm{Directional}\_\mathrm{Coeff}(\mathrm{AOA}\_{\mathrm{est}}_{i,k})-{\mathrm{PathLoss}}_{i,k})$

Formula 7

Wherein: Directional_Coeff (AOA_est _{i, k}) be the figuration gain that AOA finds on GOB directional diagram.

RNC side periodic maintenance one considers the interference reference quantity in direction, chooses a kind of periodic maintenance as following table to each community:

TCP ' represents the slot transmission power after weighted direction

To need for current the UE using new resources in Target cell, the interference reference information that first two steps can be used to obtain at RNC carries out interference to be evaded.

TCP ' is revised TCP value, still reports with the percents of maximum transmission power, by certain processing method, the TCP ' of (between RSPA plate) adjacent area between plate can be made to obtain in the storage area of this plate neighboring BS information.

For N number of homogeneous-frequency adjacent-domain of all current time slots, for Target cell jth carrier wave h descending time slot, calculate its priority, because statistical is a lot, illustrating here is only wherein two kinds:

When precise evaluation switch opens,

$P_{j,h}=\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{{\mathrm{TCP}}^{\′}}_{i,j,h,\mathrm{AOA}}$ (formula 8)

When precise evaluation switch cuts out,

$P_{j,h}=\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{{\mathrm{TCP}}^{\′}}_{i,j,h}$ (formula 9)

As can be seen from above-mentioned enforcement.In mode one, TCP ' _{i, j, h}account form is:

or TCP ' _{i, j, h}=TCP _{i, j, h};

P _{j, h}account form is:

$P_{j,h}=\frac{\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{\mathrm{TCP}}_{i,j,h}\×{10}^{\frac{\mathrm{MaxTrans}{\mathrm{Power}}_i+{\mathrm{\α}}_i}{10}}}{\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{10}^{\frac{\mathrm{MaxTrans}{\mathrm{Power}}_i}{10}}},$

Or,

$P_{j,h}=\frac{{\mathrm{TCP}}_{t,j,h}\×{10}^{\frac{\mathrm{Max}{\mathrm{TransPower}}_t}{10}}+\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{\mathrm{TCP}}_{i,j,h}\×{10}^{\frac{M{\mathrm{axTransPower}}_i+{\mathrm{\α}}_i}{10}}}{{10}^{\frac{\mathrm{Max}{\mathrm{TransPower}}_t}{10}}+\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{10}^{\frac{{\mathrm{MaxTransPower}}_i}{10}}}.$

In mode two, TCP ' _{i, j, h}account form is:

${{\mathrm{TCP}}^{\′}}_{j,k,h}=\underset{k=1}{\overset{K}{\mathrm{\Σ}}}({\mathrm{TCP}}_{j,k,h}/{\mathrm{BRU}\_\mathrm{NUM}}_k-{\mathrm{PathLoss}}_{i,k})$

Or,

${{\mathrm{TCP}}^{\′}}_{j,k,h}=\underset{k=1}{\overset{K}{\mathrm{\Σ}}}({\mathrm{TCP}}_{j,k,h}/{\mathrm{BRU}\_\mathrm{NUM}}_k\×\mathrm{Directional}\_\mathrm{Coeff}(\mathrm{AOA}\_{\mathrm{est}}_{i,k})-{\mathrm{PathLoss}}_{i,k}).$

P _{j, h}account form is:

$P_{j,h}=\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{{\mathrm{TCP}}^{\′}}_{i,j,h,\mathrm{AOA}}$ Or $P_{j,h}=\underset{i=1}{\overset{N}{\mathrm{\Σ}}}{{\mathrm{TCP}}^{\′}}_{i,j,h}.$

Wherein, mode one is a kind of simplification evaluation measures; Second mode is one evaluation measures more accurately; Two kinds of modes have all used this statistic of TCP, and a mode one parameter alpha characterizes the weight coefficient of path loss change; And mode two is except TCP, also directive gain (directional_coeff) be have selected to each UE, and accurate circuit loss value (pathloss), so more accurate than alpha.

Three, the determination of the community of interference coordination is carried out.

When determining slot priorities, need to determine each interference adjacent cell, below to how determining that interference adjacent cell is described.

Fig. 3 is the cell determining method implementing procedure schematic diagram carrying out interference coordination, as shown in the figure, can comprise the steps:

The measurement report that step 301, acquisition UE report;

Step 302, obtain the Pilot Measurement of cell-of-origin, Target cell and other adjacent area according to measurement report;

Step 303, determine the community of carrying out interference coordination according to Pilot Measurement.

When obtaining the measurement report that UE reports, can one of in the following manner or combination obtain measurement report:

The internal measurement report acquisition measurement report that the alien frequencies event that the same frequency event reported by UE in handoff procedure obtains measurement report, reported by UE in handoff procedure is obtained measurement report, reported by UE in handoff procedure.

Concrete, step 301,302 enforcement in, the same frequency event (as 1G) that can report according to UE in handoff procedure, alien frequencies event (as 2A), inner (additional with frequency/alien frequencies) measurement report, obtain the Pilot Measurement of cell-of-origin, Target cell and other adjacent area, and will the Neighboring Cell List of Target cell be obtained, can AdjCellList be denoted as in enforcement.

In enforcement, obtaining Pilot Measurement is do for the resource selection under handoff scenario, so in order to simple implementation, can adopt handover measurement reporting information to select the community will carrying out interference coordination; Certainly, each NodeB and UE measurement under RNC can be allowed to report, but implement more complicated like this.

In the enforcement of step 303, when determining the community of carrying out interference coordination according to Pilot Measurement, the community of carrying out interference coordination can be determined in the following manner:

PCCPCH_RSCP _targetCell-PCCPCH_RSCP _otherCell-i< δ (formula 10), wherein:

PCCPCH_RSCP _targetCellfor the Pilot Measurement value of Target cell,

PCCPCH_RSCP _otherCell-ifor the Pilot Measurement value of adjacent area i,

δ is Target cell and neighbor pilot difference, in enforcement, in order to avoid being selected in of too many more weak adjacent area, therefore sets this thresholding.

In formula, the PCCPCH of PCCPCH_RSCP is basic Common Control Physical Channel (Primary Common Control Physical Channel), RSCP is received signal code power (Received Signal Code Power).This value is selected to use, because this value generally can be thought " reception pilot signal strength ", that a UE accesses community, and the important parameter used in the judgement of switching cell, namely this value must be greater than a certain thresholding just accessible (such as-85dBm), this value difference of two communities is greater than some thresholdings just can adjudicate switching, and therefore this value is one of crucial factor, therefore selects it.In enforcement, also can adopt other parameters, be want to reach phase same-action.

Concrete, for each adjacent area, just can judge by after the Pilot Measurement of searching each community in AdjCellList.

Further, can further include in enforcement: when not comprising cell-of-origin in the community of determining to carry out interference coordination according to Pilot Measurement, cell-of-origin is increased in the community of carrying out interference coordination.

Concrete, be met all interference Neighboring Cell List of formula 10; If list does not comprise cell-of-origin, then supplement and add, and think that the pilot tone of cell-of-origin is PCCPCH_RSCP _targetCell-th _{switch relative threshold}, in order to increase, the weighting of cell-of-origin interference is considered.In enforcement, in formula 10, do not comprise the judgement of cell-of-origin, but after being met all interference Neighboring Cell List of formula 10, if list does not comprise cell-of-origin, then supplementing and add, and think that the pilot tone of cell-of-origin is PCCPCH_RSCP _targetCell-th _{switch relative threshold}, to increase, the weighting of cell-of-origin interference is considered.Due to the N number of dB in cell-of-origin should be greater than in Target cell, the switching dependent threshold namely in formula when switching, so be weighted to Target cell pilot value-relative threshold to it.

The object of above-mentioned enforcement is: use adjacent area that handover measurement reports to determine the scope of interference coordination alternative cell; And poor according to the received power of switching UE to Zhong Ge adjacent area, interference coordination alternative cell, remove the adjacent area that interference is more weak, thus avoided multiprocessing and increased error; Finally also supplemented cell-of-origin and enter, it is more thorough to make the consideration of interference.
