Embodiment

Technical scheme provided by the present invention has finally solved descending interfere information and has obtained inadequate situation, makes new UE more accurate to the assessment of descending interference when the Resources allocation of Target cell, thereby reduce, disturbs, and 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 resource distribution for Target cell, so application Zhong Zhe community refers to Target cell; Meanwhile, in implementation, variable all be take dBm actual value as unit.

The community of first how to confirm being carried out to interference coordination describes, and then the definite of time slot priority is described, and finally the sortord of time slot priority is described.

One, carry out the determining of community of interference coordination.

Fig. 1 is the cell determining method implementing procedure schematic diagram that carries out interference coordination, as shown in the figure, can comprise the steps:

Step 101, obtain the measurement report that UE reports;

Step 102, according to measurement report, obtain the pilot measurement result of cell-of-origin, Target cell and other adjacent area;

Step 103, according to pilot measurement result, determine the community carry out interference coordination.

When obtaining the measurement report that UE reports, one of can be 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 reporting by UE in handoff procedure obtains measurement report, report by UE in handoff procedure is obtained measurement report, reported by UE in handoff procedure.

Concrete, in step 101,102 enforcement, 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 result of cell-of-origin, Target cell and other adjacent area, and will obtain the Neighboring Cell List of Target cell, in enforcement, can be denoted as AdjCellList.

In enforcement, obtaining pilot measurement result is to do for the resource selection under handoff scenario, so for simple implementation, can adopt handover measurement reporting information to select to carry out the community of interference coordination; Certainly, can allow each NodeB and UE measurement under RNC report, but implement more complicated like this.

In the enforcement of step 103, when carrying out the community of interference coordination according to pilot measurement result is definite, can determine in the following manner the community of carrying out interference coordination:

PCCPCH_RSCP _targetCell-PCCPCH_RSCP _otherCell-i< δ (formula 1), wherein:

PCCPCH_RSCP _targetCellfor the pilot measurement end value of Target cell,

PCCPCH_RSCP _otherCell-ifor the pilot measurement end value of adjacent area i,

δ is Target cell and adjacent area pilot tone difference, in enforcement, for fear of being selected in of too many weak adjacent area, therefore set this thresholding.

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

Concrete, for each adjacent area, after searching the pilot measurement result of each community in AdjCellList, just can judge.

Further, in enforcement, can further include: in determining the community of carrying out interference coordination according to pilot measurement result, do not comprise that Shi，Jiang cell-of-origin, cell-of-origin increases into carrying out in the community of interference coordination.

Concrete, be met all interference Neighboring Cell List of formula 1; If list does not comprise cell-of-origin, 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 that cell-of-origin is disturbed, consider.In enforcement, in formula 1, do not comprise the judgement of cell-of-origin, but after being met all interference Neighboring Cell List of formula 1, if list does not comprise cell-of-origin, 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 that cell-of-origin is disturbed, consider.Should be greater than a cell-of-origin N dB in Target cell owing to switching, i.e. switching dependent threshold in formula, so be weighted to Target cell pilot value-relative threshold to it.

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

Two, determining time slot priority.

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

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

Step 202, according to TCP, determine time slot priority.

In enforcement, in step 201, the interference adjacent cell of the required TCP of obtaining can adopt determined community of carrying out interference coordination in scheme one, so just can utilize determined community of carrying out interference coordination, determine in the time slot priority that travels through and attempt access time institute's foundation according to time slot priority query.But, for each, disturb adjacent cell, also can adopt other conventional meanses to determine, just adopt that aforesaid way determines carry out the community of interference coordination time, can be because using adjacent area that handover measurement reports, poor etc. former thereby can obtain better effect to the received power of Zhong Ge adjacent area, interference coordination alternative cell according to switching UE.

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 percentage form of maximum transmission power, by certain processing method, can make the TCP of adjacent area between RSPA (Radio network Signalling Process Assemble, radio network signaling disposable plates) plate obtain in the storage area of this plate neighboring BS information.When implementing by certain processing method, such as a kind of simple processing method is, utilize between different signal command boards, to have existed in RNC in communication mode, to add the TCP information that transmits.

Performing step at 202 o'clock, according to TCP, determining in the enforcement of time slot priority, mode is below provided in embodiment, the following describes as follows:

Mode one

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

TCP is processed in the following manner:

${\mathrm{TCP}}_{j,j,h}^{\&prime;}={\mathrm{TCP}}_{i,j,h}\&times;{10}^{\frac{{\mathrm{\&alpha;}}_i}{10}},$ α _ifor the path loss weighted value calculating by PCCPCH information;

When Dang Ge community PCCPCH transmitting power is identical:

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

When Huo，Ge community PCCPCH transmitting power is different:

α _i=(PCCPCH_RSCP _i-PCCPCH_Power _i)-(PCCPCH_RSCP _t-PCCPCH_Power _t) (formula 3)

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

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

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

PCCPCH_Power represents the transmitting power of PCCPCH.

Concrete, for each, disturb adjacent area, because TCP value is the transmitting power of NodeB side, therefore can consider a path loss weight coefficient, in enforcement, can set a switch control, by it, decide under present case, whether to need this weighting.Weighting scheme can not enumerate, and formula 2, formula 3 are two kinds of weights account forms wherein.Wherein, formula 2 thinks that all cell downlink maximum transmission power are identical, and formula 3 has considered that all cell downlink maximum transmission power may be different.

The effect that path loss weighting is processed is to revise the potential serious interference degree in homogeneous-frequency adjacent-domain, because TCP is the transmitting power of base station, there is no path loss impact, therefore need to revise, in order to avoid Yu compare Jin community, compare Yuan community TCP consistent, but may cause the situation of disturbing different impact to UE.So take formula 2, formula 3 in embodiment has carried out implementation as example; But, in theory, by other mode, be also fine, as long as can realize, revise the potential interference strength this purpose in homogeneous-frequency adjacent-domain, formula 2, formula 3 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 2, formula 3, in implementation process, can need to carry out to determine in conjunction with practice the processing mode of corresponding path loss weighting.

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

if closed, directly use current TCP value

the meaning of its value is still percentage.

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

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

In concrete enforcement, when Target cell is counted to interference effect, a switch can be simply set, in order to control whether Target cell is counted to 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.

According to aforesaid way, determining after the TCP of time slot priority, in execution step 202, can implement as follows:

$P_{j,h}=\frac{\underset{i=1}{\overset{N}{\mathrm{\&Sigma;}}}{\mathrm{TCP}}_{i,j,h}\&times;{10}^{\frac{{\mathrm{MaxTransPower}}_i+{\mathrm{\&alpha;}}_i}{10}}}{\underset{i=1}{\overset{N}{\mathrm{\&Sigma;}}}{10}^{\frac{{\mathrm{MaxTransPower}}_i}{10}}}$ (formula 4)

Or,

$P_{j,h}=\frac{{\mathrm{TCP}}_{t,j,h}\&times;{10}^{\frac{{\mathrm{MaxTransPower}}_t}{10}}+\underset{i=1}{\overset{N}{\mathrm{\&Sigma;}}}{\mathrm{TCP}}_{i,j,h}\&times;{10}^{\frac{{\mathrm{MaxTransPower}}_i+{\mathrm{\&alpha;}}_i}{10}}}{{10}^{\frac{{\mathrm{MaxTransPower}}_t}{10}}+\underset{i=1}{\overset{N}{\mathrm{\&Sigma;}}}{10}^{\frac{{\mathrm{MaxTransPower}}_i}{10}}}$ (formula 5)

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

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

For TCP _{i, j, h}, in mode one, owing to directly using TCP value, therefore also can replace with

also,, if switch opens, TCP value in adjacent area is done following processing:

if closed, directly use current TCP value

the meaning of its value is still percentage.

The reason illustrating is, in following mode two, owing to having changed 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 by Operation and Maintenance interface, all can see this parameter, also can know this parameter by RNC.

In concrete enforcement, when calculating time slot priority, according to the measured value obtaining and the control of two switches, can add up total interference value to h descending time slot of j carrier wave of Target cell, N is for disturbing adjacent area number; Using TCP measured value like this, control through two switches, and the consideration of path loss weighting, finally obtain time slot priority, because concrete account form is a lot, as long as total can count the mode of the interference value of a time slot and can adopt, can not enumerate here, in two kinds of above-mentioned modes, formula 4 has been described a kind of priority account form of not considering Target cell TCP; 5 of formula have been described a kind of priority account form of considering Target cell TCP.

Mode two

In each carrier wave of each community under current RNC, descending time slot TCP cycle, upgrade, in order to interference coordination with reference to time, because TCP is NodeB public measured value, and may there is the different UE in a plurality of positions in this descending time slot, these UE are different from the position relation of current switching UE, and the interference causing is not identical yet.Therefore, further, can also implement as follows to reach descending interference assessment more accurately.

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

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

1), configure all UE periodic report pilot measurements.

2), introduce new event definition, when meeting entry condition or meeting, all trigger UE report measurement report while leaving condition.The general measurement report that switches use reporting measurement reports when meeting entry condition only, in order to support the measurement report that interference coordination needs, has added at the satisfied UE reporting measurement reports that also triggers while leaving condition.Whether can control by a parameters R eportOnLeave meeting reporting measurement reports while leaving condition.Specifically can be with reference to the A3 event implementation in TS36.331.

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

The meaning of proofreading and correct is that user AOA direction is tabled look-up on GOB directional diagram, and obtains the actual the party possible figuration gain that makes progress, for the weighting to transmitting power below, to embody the effect of intelligent antenna figuration.

To carrying out angular divisions according to the AOA of each reporting of user, the enforcement of calculating more accurately descending interference describes below.

For the alone family of every time slot, directly TCP is deposited in to the corresponding list cell of maximum direction.

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

RNC side is preserved GOB (the Grid Of Beam of the coupling antenna type of different districts, beam scanning method) directional diagram, according to the estimation of AOA, in directional diagram, take AOA direction as maximum, and with for example, angle within a thresholding (3dB) of figuration direction maximum, confirm its position in following table.For multi-user, a plurality of users' directional diagram need to be superposeed, and consideration and the angle of figuration direction maximum in a threshold range, deposit in respectively.

For aforesaid way, only preserved the angle of maximum direction and disturbed, do not think over the impact of secondary lobe, can more carefully the every user side who completes be deposited in to stack considering, at next step, superpose, to obtain better effect.Inaccuracy because directional diagram is estimated, may more produce effect for larger differential seat angle here.

RNC side can one of periodic maintenance have been considered the interference reference quantity of direction, can pass through a switch here, considers to carry out the interference assessment of different accuracy.When switch cuts out, consider a kind of rough assessment, to a kind of periodic maintenance of choosing of each community as following table, for angular range, can select any spacing, only example is wherein a kind of below:

For certain carrier wave, take certain sector as example, every 10 degree retain a value, and TCP ' represents the time slot transmitting 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 6)

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

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

${{\mathrm{TCP}}^{\&prime;}}_{j,k,h}=\underset{k=1}{\overset{K}{\mathrm{\&Sigma;}}}({\mathrm{TCP}}_{j,k,h}/\mathrm{BRU}\_{\mathrm{NUM}}_k-{\mathrm{PathLoss}}_{i,k}),$ (formula 7)

BRU_NUM _krefer to k BRU (Basic Resource Unit, the basic resources unit) number that user is shared.

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

${{\mathrm{TCP}}^{\&prime;}}_{j,k,h,\mathrm{AOA}}=\underset{k=1}{\overset{K}{\mathrm{\&Sigma;}}}({\mathrm{TCP}}_{j,k,h}/\mathrm{BRU}\_{\mathrm{NUM}}_k\&times;\mathrm{Directional}\_\mathrm{Coeff}(\mathrm{AOA}\_{\mathrm{est}}_{i,k})-{\mathrm{PathLoss}}_{i,k})$ Formula 8

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

One of RNC side periodic maintenance has been considered the interference reference quantity of direction, to a kind of periodic maintenance of choosing of each community as following table:

For the current UE that need to use new resources in Target cell, at RNC, can use interference reference information that first two steps obtain to disturb and evade.

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

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

When precise evaluation switch opens,

$P_{j,h}=\underset{i=1}{\overset{N}{\mathrm{\&Sigma;}}}{{\mathrm{TCP}}^{\&prime;}}_{i,j,h,\mathrm{AOA}}.$ (formula 9)

When precise evaluation switch cuts out,

$P_{j,h}=\underset{i=1}{\overset{N}{\mathrm{\&Sigma;}}}{{\mathrm{TCP}}^{\&prime;}}_{i,j,h}$ (formula 10)

By above-mentioned enforcement, can be found out.In mode one,

account form is:

${\mathrm{TCP}}_{i,j,h}^{\&prime;}={\mathrm{TCP}}_{i,j,h}\&times;{10}^{\frac{{\mathrm{\&alpha;}}_i}{10}}$ Or ${\mathrm{TCP}}_{i,j,h}^{\&prime;}={\mathrm{TCP}}_{i,j,h};$

P _{j, h}account form is:

$P_{j,h}=\frac{\underset{i=1}{\overset{N}{\mathrm{\&Sigma;}}}{\mathrm{TCP}}_{i,j,h}\&times;{10}^{\frac{{\mathrm{MaxTransPower}}_i+{\mathrm{\&alpha;}}_i}{10}}}{\underset{i=1}{\overset{N}{\mathrm{\&Sigma;}}}{10}^{\frac{{\mathrm{MaxTransPower}}_i}{10}}},$

Or,

$P_{j,h}=\frac{{\mathrm{TCP}}_{t,j,h}\&times;{10}^{\frac{{\mathrm{MaxTransPower}}_t}{10}}+\underset{i=1}{\overset{N}{\mathrm{\&Sigma;}}}{\mathrm{TCP}}_{i,j,h}\&times;{10}^{\frac{{\mathrm{MaxTransPower}}_i+{\mathrm{\&alpha;}}_i}{10}}}{{10}^{\frac{{\mathrm{MaxTransPower}}_t}{10}}+\underset{i=1}{\overset{N}{\mathrm{\&Sigma;}}}{10}^{\frac{{\mathrm{MaxTransPower}}_i}{10}}}.$

In mode two,

account form is:

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

Or,

${{\mathrm{TCP}}^{\&prime;}}_{j,k,h,\mathrm{AOA}}=\underset{k=1}{\overset{K}{\mathrm{\&Sigma;}}}({\mathrm{TCP}}_{j,k,h}/\mathrm{BRU}\_{\mathrm{NUM}}_k\&times;\mathrm{Directional}\_\mathrm{Coeff}(\mathrm{AOA}\_{\mathrm{est}}_{i,k})-{\mathrm{PathLoss}}_{i,k}).$

P _{j, h}account form is:

$P_{j,h}=\underset{i=1}{\overset{N}{\mathrm{\&Sigma;}}}{{\mathrm{TCP}}^{\&prime;}}_{i,j,h,\mathrm{AOA}}$ Or $P_{j,h}=\underset{i=1}{\overset{N}{\mathrm{\&Sigma;}}}{{\mathrm{TCP}}^{\&prime;}}_{i,j,h}.$

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

Three, the sortord of time slot priority.

The method implementing procedure schematic diagram of Fig. 3 for accessing by the sequence of time slot priority, as shown in the figure, can comprise the steps:

Step 301, in current SDCA time slot priority query, shielding TCP interference value is greater than the DL time slot of thresholding;

Step 302, according to shielding after SDCA time slot priority list access;

Step 303, the UE of access failure is carried out to reduction of speed;

If still with regard to access failure, all UL, DL time slot are all obtained after time slot priority list according to the sequence of SDCA time slot queuing strategy after step 304 reduction of speed, access.

All UL, DL time slot refer to that those time slots of deleting at the DL time slot of deleting TCP interference value and be greater than thresholding are at interior all time slots.

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

In order to prevent that certain carrier wave from both having existed the DL time slot of TCP maximum, there is again the DL time slot of TCP minimum, this carrier wave that finally comprehensively gets off is still come situation above.Here adopt 2 resources of taking turns 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, and according to above-mentioned said SDCA carrier wave/time slot queuing strategy, sorts, and obtains carrier wave/time slot priority list, accesses.During carrier wave sequence, the total number of DL time slot need to deduct deleted time slot.If access failure, need to attempt reduction of speed, if still just failure after reduction of speed enters next round.

				Carrier wave 1TS2/TS3	?	Carrier wave 2TS2/TS3	?
Carrier wave 1TS2/TS4	?	Carrier wave 2TS2/TS4	?
				Carrier wave 1TS2/TS5	?	Carrier wave 2TS2/TS5	?
Carrier wave 1TS2/TS6	?	Carrier wave 2TS2/TS6	?
				……	……	……	……
