In wireless network, adjacent base station can cause co-channel interference if be operated on the same center frequency point.General, carrier wave frequency range relates to center carrier frequence and corresponding two compositing factors of bandwidth.For example; at Long Term Evolution (Long Term Evolution; LTE) in the network; (evolved Node B is operated on the center frequency point of 2 gigahertz (GHZ)s (GHz) when eNB) sending downstream signal evolved base station, and bandwidth is 5 megahertzes (MHz); usually the 5MHz bandwidth further can be divided into Resource Block (Resource Block; RB), be called again Physical Resource Block (Physical Resource Block, PRB).Each PRB is made of 12 carrier waves, and each carrier wave is generally 15KHz or 7.5KHz.(User Equipment UE) can receive the interference of the downstream signal that transmits in the same frequency resource with frequently cell base station from neighbours to be in the subscriber equipment of cell edge region.Here the Radio Resource of mentioning is the Radio Resource of frequency domain.In order to reduce the interference that UE is subjected to, need utilize interference coordination technique.

In order to reduce descending interference, need to carry out downlink interference collaboration between the eNB.Source eNB sends a Relative Narrowband TX Power (Relative Narrowband Tx Power, RNTP) threshold value (threshold) and PRB corresponding relative arrowband transmission power indicative information with it to target eNB.This indication information is bit information, is defined as follows:

Wherein

Be Relative Narrowband TX Power ratio, it is worth less than RNTP _ThresholdThe time, the arrowband transmission power indicative information is 0 relatively, if to Relative Narrowband TX Power ratio, is in the nature the transmitting power on this PRB, does not do ceiling restriction, then is 1.n _PRBNumber number that identifies this PRB is n,

Source base station is transmitted to target BS with the relative arrowband transmission power indicative information formation bit diagram of all PRB correspondences.Bit diagram (10001...) for example, the relative arrowband transmission power indicative information of first " 1 " sign PRB0 is 1, namely the Relative Narrowband TX Power ratio of PRB0 is not done ceiling restriction, the relative arrowband transmission power indicative information of second " 0 " sign PRB1 is 0, be the Relative Narrowband TX Power ratio of PRB1 less than the Relative Narrowband TX Power threshold value, it is lower in the transmitting power of PRB1 to imply source base station.Here, E _A(n _PRB) refer to foreseeable a period of time in future at interval among the Physical Resource Block PRB at antenna port p, OFDM (Orthogonal Frequency Division Multiplexing, OFDM) in the symbol do not comprise reference signal based on subscriber equipment Physical Downlink Shared Channel (Physical Downlink Shared Channel, PDSCH) the maximum rated ERPE of resource element correspondence (Energy Per Resource Element) value; RNTP _ThresholdExpression numerical value, scope is RNTP _Threshold∈ ∞ ,-11 ,-10 ,-9 ,-8 ,-7 ,-6 ,-5 ,-4 ,-3 ,-2 ,-1,0 ,+1 ,+2 ,+3}[dB].

Be defined as follows: $E_{\max \_\mathrm{nom}}^{\left(p\right)}=\frac{P_{\max }^{\left(p\right)}\·\frac{1}{\mathrm{\Δf}}}{N_{\mathrm{RB}}^{\mathrm{DL}}\·N_{\mathrm{SC}}^{\mathrm{RB}}}$

Wherein,

Be the peak power output of base station,

The number of expression downlink resource piece RB (Resource BLock),

Identify the number of the subcarrier (subcarrier) among the RB.Δ f is the bandwidth of subcarrier.

Above-mentioned definition based on PRB also can change the definition based on new unit Radio Resource into.Corresponding parameters or ratio also change the Radio Resource respective value based on new unit into.For example, be revised as

The unit Radio Resource (Unit Resource Block) that the URB sign is new.

$E_{\max \_\mathrm{nom}}^{\left(p\right)}=\frac{P_{\max }^{\left(p\right)}\·\frac{1}{\mathrm{\Δf}}}{N_{\mathrm{URB}}^{\mathrm{DL}}\·N_{\mathrm{SC}}^{\mathrm{URB}}}$

Wherein,

The number of representing descending URB,

Identify the number of the subcarrier among the URB.

If in a carrier frequency band 100 PRB are arranged, then form one by the bitmap (bitmap) of 0 or 1 100 bit informations forming.A carrier frequency band may be made up of a plurality of PRB, if the ratio of the RNTP of source eNB on PRB is no more than predetermined RNTP threshold value, then the value on bitmap of this PRB correspondence is 0, otherwise is 1." 1 " hint source eNB high-power UE that calls on this PRB, and generally, this hints that also source eNB utilizes this PRB that the UE that is in remote cell edge has been carried out scheduling.After target eNB receives this information, can on the PRB of correspondence, not send signal or low-power transmit signals, or not to UE operation dispatching on identical frequency domain resource of own fringe region, to avoid the descending interference that possible source eNB uses the UE of corresponding PRB resource.Yet said method is only applicable to traditional homogeneous network, the network that namely only has macro base station (Macro) to dispose.In homogeneous network, all base station sizes are identical, and performance characteristics approaches, and it is similar to dispose the wireless environment that forms.

Along with the introducing of heterogeneous network, in order to promote the throughput of overall network, in macro base station, disposed small base station (for example, little base station Pico).For macro base station, the residing position of the Macro of Pico and other isomorphisms is different, and may only take a part of frequency domain resource, therefore existingly uses the method for identical RNTP threshold value no longer to be appropriate to interference coordination to all PRB.

Below with reference to the flow process of Fig. 1 description according to the method for the coordinating district interference of the downlink side of the embodiment of the invention.

11, the first base stations generate interference coordination information, and this interference coordination information comprises the RNTP threshold information corresponding with the Radio Resource of specified dimension.Here, specified dimension can comprise at least one in the following dimension: time, frequency and space, time for example, frequency, space, the combination of time and frequency, the combination of the time and space, the combination in frequency and space, the perhaps combination in time, frequency and space.

Generally speaking, the specified dimension of time is characterized by specific radio frames or subframe or OFDM symbol, perhaps specific radio frames or subframe or the OFDM symbol in the designated period time.The specified dimension of frequency is characterized by the frequency band of wireless resource block PRB or other specified width, which width.The specified dimension in space is characterized by the assigned direction angle of base station, perhaps the appointment angle of arrival of base station, perhaps space specified position.

In addition, interference coordination information also comprises indication bit information, whether the RNTP ratio that this indication bit information is used to indicate first base station unit wireless resource block corresponding with the Radio Resource of specified dimension surpass the RNTP threshold value corresponding with the Radio Resource of specified dimension, and whether the upper limit that perhaps is used to indicate the Relative Narrowband TX Power ratio of first base station unit wireless resource block corresponding with the Radio Resource of specified dimension limits.For example, if the RNTP ratio of the unit wireless resource block that first base station is corresponding with the Radio Resource of specified dimension surpasses the RNTP threshold value corresponding with the Radio Resource of specified dimension, perhaps the RNTP ratio upper limit to first base station unit wireless resource block corresponding with the Radio Resource of specified dimension does not limit, and the value of indication bit information is 1; Perhaps the RNTP ratio of the unit wireless resource block corresponding with the Radio Resource of specified dimension as if first base station surpasses the RNTP threshold value corresponding with the Radio Resource of specified dimension, and the value of indication bit information is 0.If when specified dimension only comprised frequency dimension, interference coordination information can comprise the corresponding RNTP threshold information of Radio Resource a plurality of and specified dimension.So, can consider to embody two covers or the above corresponding RNTP threshold information of the Radio Resource with specified dimension of two covers with two or more indication bit information, also can consider to embody two covers or the corresponding RNTP threshold information of the Radio Resource with specified dimension more than two covers an indication bit information.

Particularly, many cover indication bit information are used to indicate the comparative result of the Relative Narrowband TX Power ratio of unit wireless resource block of first base station Relative Narrowband TX Power threshold value corresponding with a plurality of Radio Resources described and specified dimension, the Relative Narrowband TX Power ratio of the unit wireless resource block of described first base station refers to the Relative Narrowband TX Power ratio of the corresponding unit wireless resource block of the Radio Resource of specified dimension of the Relative Narrowband TX Power threshold value corresponding with Radio Resource specified dimension that compare with it.Like this, at each RNTP threshold value corresponding with the Radio Resource of specified dimension, have a bitmap, this bitmap table is understood the RNTP ratio of unit Radio Resource corresponding in the bitmap and the comparative result of RNTP threshold value.The base station sends to the another one base station with a plurality of RNTP threshold values and corresponding bitmap.

Particularly, one cover indication bit information is used to indicate the comparative result of the Relative Narrowband TX Power ratio of unit wireless resource block of described first base station Relative Narrowband TX Power threshold value corresponding with the Radio Resource of the described and specified dimension of appointment, the Relative Narrowband TX Power ratio of the unit wireless resource block of described first base station, refer to the Relative Narrowband TX Power ratio of the corresponding unit wireless resource block of the Radio Resource of specified dimension of the corresponding Relative Narrowband TX Power threshold value of the Radio Resource of described and specified dimension of the appointment that compares with it, wherein the Relative Narrowband TX Power threshold value that the Radio Resource of the described and specified dimension of appointment is corresponding is in the corresponding Relative Narrowband TX Power threshold value of a plurality of Radio Resources described and specified dimension one.Like this, the unit wireless resource block of base station only can select a RNTP threshold value corresponding with the Radio Resource of specified dimension to compare with it, the RNTP ratio of the unit Radio Resource of this base station be the Radio Resource of specified dimension of the RNTP threshold value corresponding with the Radio Resource of this specified dimension corresponding RNTP ratio.The base station with a message bit pattern and or message bit pattern in the RNTP threshold information of every correspondence send to the another one base station.If the corresponding identical RNPT threshold information of multidigit is arranged, the base station can be represented with a RNPT threshold information.

12, the first base stations send interference coordination information to second base station, so that the interference coordination strategy is determined according to this interference coordination information in second base station, to reduce the interference on same sub-band of first base station and second base station.

Optionally, first base station also can send interference coordination information to third party's node earlier, by this third party's node interference coordination information is transmitted to second base station again.General, third party's node is Operations,Administration And Maintenance (OAM, Operation Administration and Maintenance) or UE.

Below with reference to Fig. 2 the flow process according to the method for the coordinating district interference of the downlink side of the embodiment of the invention with respect to method shown in Figure 1 is described.

21, the second base stations receive the interference coordination information that first base station sends, and interference coordination information comprises the RNTP threshold information corresponding with the Radio Resource of specified dimension.Here, specified dimension can comprise at least one in the following dimension: time, frequency or space, time for example, frequency, space, the combination of time and frequency, the combination of the time and space, the combination in frequency and space, the perhaps combination in time, frequency and space.

Optionally, second base station receives the interference coordination information that third party's node is transmitted, and wherein this interference coordination information sends to third party's node by first base station, for example OAM or UE.

The interference coordination strategy is determined according to interference coordination information in 22, the second base stations, to reduce the interference on same sub-band of first base station and second base station.

For example, when the RNTP ratio of first base station unit wireless resource block corresponding with the Radio Resource of specified dimension surpasses the RNTP threshold value corresponding with the Radio Resource of specified dimension, perhaps the upper limit to the Relative Narrowband TX Power ratio of first base station unit wireless resource block corresponding with the Radio Resource of specified dimension does not limit, then second base station is determined not dispatch at this subband, perhaps determines to be reduced in the transmitting power on this subband.

For example, when the RNTP ratio of first base station unit wireless resource block corresponding with the Radio Resource of specified dimension surpasses the RNTP threshold value corresponding with the Radio Resource of specified dimension, then second base station is determined and can be dispatched at this subband, perhaps determines to improve the transmitting power on this subband.

Below with reference to the flow process of Fig. 3 description according to the method for the coordinating district interference of third party's node side of the embodiment of the invention.

31, receive interference coordination information from first base station, wherein interference coordination information comprises the RNTP threshold information corresponding with the Radio Resource of specified dimension, wherein this specified dimension comprises at least one in the following dimension: time, frequency or space.This interference coordination information also comprises indication bit information, whether the RNTP ratio that this indication bit information is used to indicate first base station unit wireless resource block corresponding with the Radio Resource of specified dimension surpass the RNTP threshold value corresponding with the Radio Resource of specified dimension, and whether the upper limit that perhaps is used to indicate the Relative Narrowband TX Power ratio of described first base station unit wireless resource block corresponding with the Radio Resource of specified dimension limits.

32, transmit this interference coordination information at least one second base station, so that the interference coordination strategy is determined according to this interference coordination information in second base station, to reduce the interference on same sub-band of first base station and second base station.

Therefore, can solve problem of co-channel interference in the network design scene according to the method for the coordinating district interference of the invention described above embodiment.Source base station generates by the RNTP threshold value and is combined the interference coordination information of sign with bit information, so that target BS is determined the interference coordination strategy based on such interference coordination information, in order to reduce by first base station and second base station co-channel interference on each subband.

The method according to the coordinating district interference of the embodiment of the invention of will illustrating below is applied to the specific embodiment in the heterogeneous network.The method according to the coordinating district interference of the embodiment of the invention that should be understood that can be applied in the homogeneous network equally.

As shown in Figure 4, Pico and Macro1 isomery are disposed, and Pico has only taken a part of frequency band in the middle of the corresponding frequency band of Macro.For fear of the descending interference to Pico, Macro1 be the Pico correspondence the PRB resource distribution RNTP threshold value, for example a ThresholdA.Accordingly, when the transmitting power of Macro1 on corresponding PRB resource is higher than ThresholdA, the bit information " 1 " of the PRB of correspondence can be sent to Pico, otherwise the bit information " 1 " of the PRB of correspondence is sent to Pico.Pico need be the PRB reduction power of " 1 " at bit information just when identical frequency domain resource scheduling UE, avoids co-channel interference, perhaps avoids edge UE scheduling on this frequency domain resource.Simultaneously, because far away with the Macro2 distance with the Macro1 that penetrates of taking place frequently, Macro1 is the RNTP threshold value of Macro2 setting, and ThresholdB for example can be more greatly.Because, Macor1 send at this moment powerful signal to the influence of Macro2 much smaller than the influence to Pico.Further, Macro1 separates a part of frequency domain resource and is not used in scheduling UE, for example allocated bandwidth is used to Pico or be used for enhanced physical down control channel (ehanced Physical Downlink Control Channel, ePDCCH), the transmit power needs of the demand of the transmitted power on the resource and other resources is different in this section for Macro1 so, may be on the low side or higher, and can send signal by the transmitted power of in the past homogeneous network on other frequency domain resource.

Adjust the transmitting power of target eNB on different PRB for the transmission power information that takes full advantage of source eNB, namely the power of source eNB and target eNB is adjusted, and then reduce co-channel interference.Source eNB need send to target eNB with different RNTP threshold informations and the bit information of different PRB correspondences, rather than all PRB use identical threshold value and provide bit information at this threshold value in the prior art.

On the contrary, when source eNB separation frequency domain resource is used to Pico, if all PRB adopt RNTP threshold T hresholdB in the past, though then the transmitting power of the frequency domain resource correspondence of this separation is lower than ThresholdB, but be reference with ThresholdA, this means that target eNB receives ThresholdB, and the bit information of discovery on the frequency domain resource of separating is less than 0, then high-power emission on identical Radio Resource, and the true RNTP threshold T hresholdA of in fact separated frequency domain resource may be very approaching with ThresholdB, causes the generation co-channel interference of this high-power emission high probability.In like manner, if Macro separates the part frequency domain resource, send with high power, if all PRB adopt identical RNTP threshold value, then also can cause the setting of target eNB transmitting power to make a mistake, and then produce co-channel interference.

Therefore, eNB is divided into a plurality of subbands with whole bandwidth, and wherein each subband can be unit with PRB, is unit with other width perhaps.ENB sends to target eNB with RNTP threshold value and the transmitting power bit information corresponding with the RNTP threshold value of subband correspondence.Here, the RNTP threshold value of each subband correspondence can be got different value according to the needs of concrete deployment scenario in the whole bandwidth.Whole bandwidth can be the part of downstream bands, and whole bandwidth is at target eNB and source eNB.After target eNB is received this information, according to RNTP threshold value and the corresponding bit information of each subband, determine whether oneself can dispatch UE at the subband of correspondence, and the size of transmitting power.

Particularly, source eNB sends to target eNB with different RNTP threshold values and the transmitting power bit information corresponding with the RNTP threshold value of PRB correspondence, so that target eNB is according to the real RNTP threshold value of each PRB and the transmitting power bit information corresponding with this RNTP threshold value, determine the transmitting power of oneself, in order to use rational power and wireless resource scheduling UE, avoid descending co-channel interference.

Further, source eNB can send RNTP threshold value and the bit information of whole bandwidth PRB correspondence to target eNB, and perhaps source eNB sends every cover RNTP threshold value and the bit information corresponding with every cover RNTP threshold value to target eNB.

Should be understood that the PRB here also can change the information that other can identify frequency band into, perhaps the frequency domain resource of other granularities.

Therefore in another embodiment, Radio Resource can comprise the information of frequency and time two dimensions, can be further interference coordination information be expanded to time-domain from frequency domain alternately.For example, in the LTE network, from the time angle, down link signal is that unit sends with the radio frames, and a radio frames is generally 10 milliseconds (ms), and wherein every 1ms is a subframe.In heterogeneous network as shown in Figure 5, in order to reduce the interference to a plurality of Pico, guarantee Macro1 with the performance of a plurality of Pico that cover frequently, Macro1 can be chosen in cycle regular hour interior low-power ground and send signal in some subframe.Such as, in the 0-9 wireless sub-frame, 0 work song frame transmits by the power P 3 of not disturbing the regional Pico3 of A point, and obviously Macro1 can not interfere with Pico2 and Pico1 at the downstream signal that this subframe sends.The throughput demand of considering Pico2 and Pico1 may be bigger than Pico3, and Macro1 can not be interfered to determine transmitting power with other subframes according to B point or C point according to the needs of Pico2 or Pico1.Accordingly, for neighbours' macro base station Macro2, need determine oneself to be used for the RNTP parameter of interference coordination and Radio Resource and the power that is used for scheduling according to the RNTP parameter of the enterprising step refining of time-domain.

In the certain hour period T, source eNB sends to target eNB with transmit power threshold on the different subframes, and the bit information that perhaps whether the RNTP ratio of the RNTP parameter (being the RNTP threshold value on the different subframes) of transmit power threshold correspondence on the different subframes and the unit wireless resource block corresponding with the Radio Resource in fixed time territory is surpassed with the corresponding RNTP threshold value of the Radio Resource in fixed time territory sends to target eNB.After target eNB is received above-mentioned information, adjust own to corresponding Radio Resource or scheduling and the transmitting power of corresponding subframe on the time.In a period of time T, the threshold value of the transmitting power on the different subframes can be different.

Further, interference coordination information further can also be refine to time-domain and frequency domain two dimension.For example, source eNB can send to target eNB with the RNTP threshold value of the Radio Resource correspondence in fixed time territory and assigned frequency territory, and perhaps target eNB sends to target eNB according to the bit information whether the RNTP ratio of the RNTP threshold value of the Radio Resource correspondence in fixed time territory and assigned frequency territory and the unit wireless resource block corresponding with the Radio Resource in fixed time territory and assigned frequency territory surpasses with the corresponding RNTP threshold value of the Radio Resource in fixed time territory and assigned frequency territory.Target eNB is determined to disturb scheduling strategy according to the interference coordination information of receiving: for example, whether dispatch UE in the resource of correspondence, perhaps with much power dispatching UE.If corresponding bit information shows that the down transmitting power of Radio Resource correspondence in fixed time territory and assigned frequency territory is greater than the RNTP threshold value, then target eNB will be according to the interference coordination information of receiving, avoid as far as possible dispatching UE in identical time-domain and frequency domain resource, perhaps with low-power scheduling UE.
