Referring now to accompanying drawing, Fig. 1 is saying of the wireless multiple access access communications system 100 according to various aspects Bright.In one example, wireless multiple-access communication system 100 includes multiple base station 110 and multiple terminal 120.Additionally, one or more base stations 110 can communicate with one or more terminals 120.Make For nonrestrictive example, base station 110 can be access point, node B and/or other suitable network Entity.Each base station 110 provides communication overlay for specific geographic area 102a-c.As herein Used and this area institute is normally used, the context used according to term " community ", art Language " community " can refer to base station 110 and/or its overlay area 102a-c.

In order to improve power system capacity, can be by overlay area 102a, the 102b corresponding with base station 110 Or 102c is divided into multiple smaller area (such as, region 104a, 104b and 104c).Each is relatively Zonule 104a, 104b and 104c can (BTS show by respective base station transceiver subsystem Go out) service.As used herein and this area institute is normally used, according to term " sector " institute The context used, term " sector " can refer to BTS and/or its overlay area.In one example, Sector 104a, 104b and 104c in community 102a, 102b or 102c can be by the sky of base station 110 Line group (not shown) is formed, and each of which group antenna is responsible for and community 102a, 102b or 102c A part in terminal 120 communicate.Such as, the base station 110 serving community 102a is permissible There is the second antenna sets that the first antenna group corresponding with sector 104a is corresponding with sector 104b And the third antenna group corresponding with sector 104c.It is to be understood that the application institute is public The various aspects opened can use in having the system of sectorization and/or un-sectorized.Additionally, also It should be appreciated that have all the most wireless of any number of sectorization and/or un-sectorized cells Communication network is within the scope of the appended claims.For simplicity, institute herein The term " base station " used can refer to the station of serving sector and the station of Serving cell.As entered herein One step uses, and " service " access point is that terminal has that with it RL business (data) is transmitted Access point, and " adjacent " (non-serving) access point is terminal and it can have FL business and/or FL And RL control transmission but there is no an access point of RL business.It should be appreciated that such as this paper institute Using, the FL sector in disjoint link scenario is adjacent sectors.Although under for simplicity, Literary composition describes and is usually directed to a kind of system, and each terminal is carried out with a Service Access Point within the system Communication, but it is to be understood that, terminal can communicate with any number of Service Access Point.

According to an aspect, terminal 120 can be scattered in system 100.Each terminal 120 can Being static or movement.As non-limiting example, terminal 120 can be access terminal (AT), Movement station, subscriber equipment, subscriber station and/or other suitable network entity.Terminal 120 can be nothing Line equipment, cell phone, PDA(Personal Digital Assistant), radio modem, handheld device or Other suitable equipment.Additionally, terminal 120 can be in any given time and any number of base station 110 Communicate or do not communicate with base station 110.

In another example, system 100 can use concentration by using system controller 130 Formula architecture, wherein system controller 130 may be coupled to one or more base station 110, and is this A little base stations 110 provide to be coordinated and controls.According to substituting aspect, system controller 130 can be Single network entity or the set of network entity.Additionally, system 100 can use distributed system Structure, in order to allow base station 110 to communicate the most each other.In one example, it is System controller 130 can additionally contain one or more connections of multiple network.These networks can To include the Internet, other packet-based network and/or circuit-switched voice network, these network energy Enough provide to/from the terminal 120 communicated with the one or more base stations 110 in system 100/obtain Information.In another example, system controller 130 can include scheduler (not shown) or Person couples mutually with scheduler, and wherein scheduler can dispatch the transmission going to and/or coming self terminal 120. Or, scheduler can also be positioned at each single community 102a-c, each sector 104a-c or In person's a combination thereof.

In one example, system 100 can use one or more multiple access schemes, such as CDMA, TDMA, FDMA, OFDMA, Single Carrier Frequency Division Multiple Access (SC-FDMA) and/or its The multiple access schemes that it is suitable.TDMA uses Time Division Multiplexing, in this scenario, logical Cross the transmission launching orthogonalization different terminals 120 in different time intervals.FDMA uses frequency division Multiplexing (FDM), in this scenario, by launching orthogonalization difference eventually in different frequency sub-carrier The transmission of end 120.In one example, TDMA and FDMA system can also use code division multiplexing (CDM) transmission of multiple terminal, in this scenario, i.e. it is used in identical time interval or frequency Subcarrier sends, it is possible to use different orthogonal codings (such as, walsh codes) comes orthogonal Change these transmission.OFDMA uses OFDM (OFDM), and SC-FDMA uses single load Ripple frequency division multiplexing (SC-FDM).OFDM and SC-FDM system bandwidth can be divided into multiple just The subcarrier (such as, tone, frequency ...) handed over, each subcarrier can be adjusted by data System.Generally, use OFDM to send modulation symbol in frequency domain, use SC-FDM time Between territory send modulation symbol.Additionally and/or alternatively, system bandwidth can be divided into one or many Individual frequency carrier, each frequency carrier can include one or more subcarrier.System 100 also may be used To use the combination of the Multiple Access scheme of such as OFDMA and CDMA etc.Although merit given herein Rate controls technology and is typically for OFDMA system description, but it is to be understood that, described herein Technology can be applied similarly to any wireless communication system.

In another example, base station 110 in system 100 and terminal 120 can use one or Multiple data channel transmission data, use one or more control transmission signaling.Can be to active The data channel that terminal 120 distribution system 100 uses so that believe in each data of any given time Road is only used by a terminal.Or, data channel can be distributed, wherein to multiple terminals 120 Can overlap or dispatch orthogonally these terminals 120 on a data channel.In order to save system money Source, it is also possible to use such as code division multiplexing shared system 100 among multiple terminals 120 to be used Control channel.In one example, with corresponding control channel compared with, only frequency and in the time just The data channel (such as, not using the data channel of CDM multiplexing) handing over multiplexing is not easily susceptible to due to letter The impact of the loss of orthogonality that the imperfection of road situation and receiver is caused.

According to an aspect, system 100 can by such as system controller 130 and/or each One or more schedulers that base station 110 realizes use centralized dispatching.Use centralized dispatching it is In system, scheduler can rely on the feedback of self terminal 120, makes suitable scheduling decision.One In individual example, in order to allow scheduler to estimate, terminal 120(is wherein fed back receives from this terminal 120) Supported reverse link peak rate and correspondingly distribution system bandwidth, described feedback can include The delta offset increased to the OSI information of feedback.

According to another aspect, within system 100, return link interferences and resources control can be to be Regiment commander comes guaranteed minimum system stability and service quality (QoS) parameter.Give one example, instead Confirm that to link (RL) decoding error probability of message can cause mistake for all forward link transmissions Substrate by mistake.By using strict interference to control on RL, system 100 can promote to control and QoS Business and/or there is the power efficient transmission of other business of stringent error requirements.

Fig. 2 shows the block diagram contributing to realizing the example system 200 of interference and communication resource management. Access terminal (AT) 220 communicates with Service Access Point (AP) 250, wherein Service Access Point 250 can on forward link (FL) 265 to AT 220 launch data and control coded identification and Data and control are received by reverse link (RL) 235.Service AP 250 can be to 220, terminal Resource is sent to distribute.The distribution of this resource transmits about the communication resource (such as, power level and/or power spectrum Density, packet format, modulation system etc.) information so that AT 220 can use this information to Just communicate with AP250.Resource distribution can be managed by scheduler 254, scheduler 254 Distribution can be determined according to the feedback information received from AT 220 on RL 235.It should be noted that It is that scheduler 254 can be connected to such as processor 258 and memorizer 262.Processor 258 can To contribute to realizing the some or all of function of scheduler 254, memorizer 262 can preserve such as The record of dispatching distribution.In one aspect, scheduler 254 can receive and the money that communicates on RL 235 The side-play amount (Δ 239) that source is relevant, in order to according to Δ 239 adjustresources grade with redistribute resource. Can use this redistribute alleviate on other sector AT 220, such as AP's 280 etc is non- The interference that service AP causes.When AP 250 redistributes relatively low to AT 220 after receiving Δ 239 value During operation power, interference can be alleviated.It should be noted that, hereinafter " Δ ", " side-play amount " and " increment " is interchangeably used, and their implication is substantially the same.Δ is discussed below Determine/adjust.

Access terminal 220 can receive information from non-serving access points 280 on forward link 295. Although depict single non-serving AP in example system 200, but it should be noted that AT 220 can To receive information from multiple non-serving AP.These access points just might be used in the moment obtaining service AP 250 To obtain, and form the active set (active set can be stored in such as memorizer 232) of AT 220. Additionally, AT 220 is after obtaining active set, can be in conjunction with the pilot power received and interference and heat Noise ratio (IoT) carries out refine according to predetermined thresholding to active set.Non-serving AP 280 can be monitored The information that (or other non-serving AP of the active set of refine) is launched/broadcasted.Specifically, AT 220 can monitor the instruction of other sector interference (OSI).It should be noted that, can also monitor AP(outside active set is refering to hereafter).Movement station is about whether monitoring the OSI from given sector The decision of instruction can FL geometrical condition based on this sector (such as, the signal of the filtering of capture pilot tone With interference plus noise ratio (SINR)) and combine prespecified thresholding.

Can launch or broadcast the instruction of excessive OSI 299 on the physical channel of forward link 295.? One aspect, in third generation Ultra-Mobile Broadband (3G UMB) system, forward direction OSI channel (F-OSICH) OSI instruction is carried.Despite system specifications, but it is to be understood that, for this The requirement of class channel is big overlay area, because this channel needs be not launched sector (such as, fan District 104a-c) decode at the access terminal that services.Specifically, the channel carrying OSI instruction is permissible The capture pilot tone having and be penetrated into nearby sectors (such as, second and the 3rd closest to sector) Channel (such as, the forward channel quality in forward direction CPICH Common Pilot Channel (F-CPICH), 3G UMB Instruction pilot channel (F-CQIPICH)) the same covering.Additionally, carry the thing of OSI 299 instruction Reason channel needs do not requiring other letter about its transmitting sector in addition to pilot frequency pseudo-random code sequence Just can be decoded in the case of breath.These requirements make: (i) carry the physical control channel of OSI instruction (such as, the F-OSICH in 3G UMB) is non-to the expense of the power required and time-frequency resources Chang Xianzhu；(ii) limit OSI and indicate the speed can launched on channel, generally, often One superframe launches an OSI instruction (refering to hereafter).In 3G UMB, similar F-OSICH it The OSI that the large coverage of the channel of class causes the sector outside the active set obtained to be launched indicates quilt Monitoring, such as, is decoded by access terminal.

Non-serving access points 280 can include OSI formation component 284, and the latter may be coupled to processor 288 and memorizer 292.Assembly 284 can be relative to Transmission Time Interval length or short time period (example As, frame, a subframe) the upper OSI 299 that generates indicates.These instruction is described below.(i) OSI at a slow speed.Long period can correspond to one or more superframe or radio frames.In one aspect, exist In 3G UMB, superframe includes 25 frames, and according to protection of time and Cyclic Prefix, superframe is permissible The most about 24-28ms.In yet another aspect, nothing in third generation Long Term Evolution (3G LTE) system Line frame continues 10ms.The OSI 299 that assembly 284 generates in above-mentioned or longer time are spaced indicates Referred to herein as " at a slow speed " OSI or regular OSI.It should be noted that, OSI can be with tested at a slow speed Average instruction in time interval (such as, a superframe) is corresponding, and when the change of channel disturbance When changing slow, it can reflect non-serving AP(such as effectively, 250) interference observed.Additionally, OSI is presenting constant transmissions pattern (such as, bandwidth in the transmitting procedure including several superframe at a slow speed (BW) distribution and buffer status be not change significantly in) sector in be effective.If in systems Have enough statistic multiplexing (such as, increase the wireless device that those BW of terminal compensation of BW reduce, Or network fully loads), OSI can also represent the interference level in sector exactly at a slow speed.

(ii) quick OSI.In some scenes, such as, load the most completely at those and burst occurs In the communication system of user, OSI 299 instruction in short time period is required.In one aspect, This scene can be realized, it may be assumed that be located adjacent to the single access of two sector borders in situations below Terminal initiates suddenly new transmission after the long enough period of mourning in silence, and to currently occurring in nearby sectors Rl transmission causes significantly interference.It should be appreciated that use is carried OSI 299 at a slow speed and is indicated Physical forward link channel (such as, the F-OSICH in 3G UMB), nearby sectors need flower This terminal that forces several super frame tim e interval reduces it and launches power to make interference drop to acceptable journey Degree.The interim extended at this, the rl transmission in this sector to bear serious interference, And experience substantial amounts of packet error.Stem from the OSI 299 of the interference measurement results of each frame or subframe Instruction is referred to herein as " quickly " OSI.

It should be appreciated that OSI formation component 284 can at each subcarrier or each subband (such as, One group of subcarrier (Fig. 4)) generate indicate with quick OSI at a slow speed.In this scene, quick OSI energy Enough (in time-frequency resources) becomes have enough granularities, enabling judge terminal A or end End B is causing observed interference.

The impact of bursty terminal (such as, access terminal 220) can disappear by using following facts Remove/alleviating, long term channel the most on the forward and reverse links is often height correlation: instead On link, non-serving sector is caused strong interference terminal can most probable at forward link (such as, Forward link 295) on observe the strong signal (such as, pilot signal) from non-serving sector, and Include this sector in its active set.Therefore, each access point in non-serving sector is (such as, Access point 280) can also be via forward link control in addition to launching OSI instruction at a slow speed to access terminal The quick OSI of channels transmit indicates, and wherein forward link control channel is compared with slow OSI indication channel There is relatively low expense.In order to realize described transmission, access terminal needs to include in just launching access point Its active set.In one aspect, this channel can be included in and can send out in 3G UMB system In the forward link fast OSI channel (F-FOSICH) penetrated.It should be appreciated that due to quickly OSI instruction may be used for the most limited a group of access terminal, and such as, those have in its active set Having the access terminal just launching AP, therefore the covering for transmission this type of information requires need not and carry The covering of the channel of OSI instruction requires the biggest at a slow speed.In yet another aspect, mentioned above F-FOSICH may reside in each FL physical layer frame (therefore disclosing the root of its name), this Allow the bursty access terminal (such as, 220) in adjacent sectors in non-serving access points (such as, 280), before causing packet error in the sector serviced, this non-serving access points eliminates rapidly/alleviates to be come From the interference of this terminal.

Then, the function of OSI formation component 284 be will be described in further detail.In order to these functions are described Aspect, being described below reference Fig. 3 and Fig. 4, Fig. 3 and Fig. 4 is the interference metric of example super frame respectively Exemplary plot 300 and frequency domain in the exemplary plot 400 of interference metric, wherein example super frame includes K Illustrative RL physical frames 310₁-310_K.It should be noted that, these frames continue AP 250 and 280 with And the specified quantitative time specified by the specification of the wireless system of AT 220 work.In one aspect, symbol Number numerology determines time span.Giving one example, in 3G UMB, multiframe can continue almost 1ms, includes the Cyclic Prefix of varying number the most in a frame, superframe include K=25 frame (with Lead code).In order to generate OSI instruction, non-serving access points (such as, non-serving AP 280) can According to it in different time-frequency resources (such as, frame 310₁-310_K) interference volume that observes makes By tolerance, and use the function of measured interference.Additionally, for the instruction sending excessive interference, can With by thresholding (or tolerance limit) interference metric values I_TH320 use as reference value.It should be appreciated that Some factors may determine that I_TH, and these factors are generally determined by service supplier: target peak Value Data speed, target spectral efficiency, target latency, the complexity of base station/access point and cost etc.. Equally, it is possible to relative to reference value I^(REF)350 weigh interference with dB, wherein reference value I^(REF)350 Can be determined by other source of the thermal noise in such as system and system noise.

In one aspect, can be designed for determining the process/method of interference level, this includes following four Individual aspect.(1) model measure can be for OSI at a slow speed and the average interference of quick OSI.Institute There is frequency resource (such as, Fig. 4 subcarrier 410₁-410_MOn) and at some (recently) reverse links Frame (such as, 310_J-310_K, wherein J < K) on averagely obtain ＜ I ＞^(slowly)330.Or, make super All frequencies in frame, the meansigma methods of each frame are by given constant (such as, 25ms, 3G UMB In the time span of a superframe) infinite-duration impulse response (IIR) wave filter, it is possible to obtain average Value.In figure 3, interfering frequency meansigma methods 340₁-340_KIt is for each frame 310₁-310_KInstruction 's.If average interference ＜ I ＞^(slowly)330 are higher than thresholding I_TH320, then OSI formation component 284 is just sent out Go out the instruction of excessive OSI.As discussed above, calculate meansigma methods and can capture wireless communication sector In slowly varying change.In one aspect, in 3G UMB system, non-serving access points (example As, 280) can be according to the long-term average (filter of the average interference measured by all frequency resources Ripple version) the OSI instruction that generates uses regular OSI channel (F-OSICH) average dry to control Disturb.About quick OSI, at such as subcarrier (such as, all subcarriers 410₁-410_MOr subcarrier 410₁-410_MA subset) or the frequency resource of subband etc on be averaged, can generate quickly Average interference value 340₁-340_K.As shown in Figure 4, can be for each subcarrier in frequency domain Determine quick OSI: value 420₁-420_MWith at particular frame, (Fig. 4 provides frame 310_JThe interference of observation in) Metric is corresponding.It should be noted that, for each frame (such as, frame 310_J), except at frequency Average (such as, ＜ I ＞ in rate resource^(soon)340_JOutside), it is also possible to by interference value 420₁-420_MDistribution To quick OSI.

Processor (such as, processor 288) can calculate these meansigma methodss, and with process (1) Relevant other calculates, and result can be saved in memorizer (such as, memorizer 292).This Outward, processor (such as, processor 288) can promote in time-frequency domain for interference level Measurement；Data can be stored in memorizer (such as, memorizer 292).

(2) for OSI at a slow speed and quick OSI, OSI formation component 284 can use one side Method, the method includes monitoring interferometry distribution (such as, value 340₁-340_KRepresent at frame 310₁-310_K On distribution) the high percentage point (such as, afterbody (tail)) of cumulative distribution function (CDF).As Described below, the interference level using the method to obtain referred to herein as is disturbing for afterbody.Monitoring Tail value is very suitable for ensureing lowest performance on a control channel and/or keeping communication, controls channel one Receiver repeat requests to be avoided (such as, hybrid automatic repeat-request (HARQ)) in the case of as, because of If there is flying up of interference level the most in a sector in this, control channel more susceptible to To packet error, the impact of information dropout.About OSI at a slow speed, OSI formation component 284 can be for Nearest frame in superframe generates the distribution (such as, 340 that each frame is average_J-340_KWith corresponding CDF), Subsequently, it is thus achieved that the tail interference value I corresponding with specific percentage point (such as, 90%)_TAIL(S)；At I_TAIL(S) Higher than I_THOSI instruction is sent in the case of 320.For quick OSI, work as I_TAIL(F)Value is higher than thresholding (such as, I^(TH)320), time, OSI formation component 284 can send OSI instruction, wherein I_TAIL(F) Corresponding with specific interference value, and this specific interference value with for a class frequency resource (such as, Value 420₁-420_M) interference level distribution CDF high percentage point be correlated with.Processor is (such as, Processor 288) these other average and relevant to this process calculating can be calculated, and permissible Result is saved in memorizer (such as, memorizer 292).Additionally, processor (such as, processes Device 288) measurement for interference level in time-frequency domain can be promoted；The data measured are permissible It is stored in memorizer (such as, memorizer 292).

(3) or, or additionally, OSI formation component 284 can use based on (1) and (2) Mixed method: for OSI at a slow speed or quick OSI, realizes having thresholding ＜ I ＞ simultaneously_THAverage interference Measure and there is thresholding I^(TAIL)Tail interference metric.When average and tail interference levels exceed respectively 〈I〉_THAnd I^(TAIL)Time, OSI formation component 284 is issued by corresponding with at a slow speed or quickly OSI excessive OSI indicates.It should be appreciated that the OSI instruction generated according to OSI formation component 284, These thresholdings are set up for OSI at a slow speed or quick OSI.Processor (such as, processor 288) can To calculate these other average and relevant to this process calculating.Data and result can be stored in In memorizer (such as, memorizer 292).Additionally, processor (such as, processor 288) is permissible Promote in time-frequency domain for the measurement of interference level；(such as, data can be stored in memorizer Memorizer 292) in.

(4) in order to generate the instruction of excessive OSI, OSI formation component 284 may determine that effectively interference Tolerance, and by itself and I_THContrast.Use valid metric can utilize system Biodiversity, such as, If using big value for specific resources (such as, one group of subcarrier) tolerance, another of same metric Individual example in different resource (such as, another organizes carrier wave) the little value of upper employing, then calculates effective degree of disturbance Amount introduces above-mentioned multiformity.Although it should be noted that, the valid metric energy of such as average tolerance etc Enough smooth these diversity fluctuations, but other valid metric can improve the pole in above-mentioned diversity profile Value.Another kind of valid metric is concept based on power system capacity.In this case, it is possible to will be at one group The different value of the interference metric calculated on time-frequency resources is converted into capability value.Can will be calculated Capability value is averaged, and can obtain effective interference metric from this meansigma methods.When calculating effectively The function of the interference level being different from capacity function can be used during tolerance.One of other function this Example is signal-to-noise ratio.

Being similar to (1) and (2), the determination of effective interference metric depends at one group of time-frequency resources (such as, frame 310₁-310_K, subcarrier 410₁-410_MThe measured value of interference level on).It is to be understood that , measured value can with in each time-frequency resources (such as, single frame, single load Ripple) on measurement corresponding, or the average shape of a subset corresponding to detection time-frequency resource The measurement of condition, such as section (tile) (such as, 16 subcarriers in a frame time span). Subsequently, the generation of valid metric uses the function (f) of interference level (I).As mentioned above, this letter Number can be capacity or signal-to-noise ratio.For each interference level in multiple measurement interference levels Carry out estimation function f, it is possible to generate the meansigma methods (A) of these results.It should be noted that, when by average When value is as valid metric (seeing above), function f is identity function, such as, and f (I)=I.Pass through Estimated service life A is as inverse function (such as, the f of the f (I) of argument value¹(A)) effective degree of disturbance is obtained Amount.If it should be appreciated that the value of all measurements is identical (such as, I_NFCorresponding to end , i.e. when detecting different time-frequency resources, in interference level, there is not fluctuation in scape), the most effectively Interference metric and described I_NFCorresponding.

Processor (such as, processor 288) can calculate these meansigma methodss, and relevant to this process Other calculate, such as calculate capacity and derivation virtual value.Data and result can be stored in memorizer In (such as, memorizer 292).Additionally, processor (such as, processor 288) can promote For the measurement of interference level in time-frequency domain；Data can be stored in memorizer (such as, storage Device 292) in.

Signal to noise ratio (snr) can be used to describe above-mentioned valid metric method as interference metric.Example As, if multiple resource can be used for (such as, subcarrier, modulation and encoding scheme, the access point that communicate With the transmitting at access node and reception antenna ...), then OSI formation component 284 can calculate SNR Multiple values.Therefore, multiple options can be used for specifying effective SNR and generating effective interference metric: (a) Average SNR；(b) average signal (＜ S ＞) and the ratio of average interference/noise (＜ I ＞)；C () uses Effective SNR(that certain capacity concept calculates such as, for single-input single-output (SISO) system Shannon capacity or multi-input multi-output system (MIMO) in Telatar-Foschini capacity). C the programming realization of () including: take the value that each SNR calculates, and each value is transformed into capacity and surveys Degree, is averaged to the capacity calculated, and generates effective SNR by capacity inverse function.OSI is raw Become assembly 284 can perform operation below.The option (c) the average fully profit by capture values below By multiformity, these values have those SNR value sensitive for the communication resource and independent of described resource or Person's those SNR value insensitive to described resource.Or, if access point (such as, AP 280) Interference value (I) can be measured in the case of not accessing corresponding signal value (S), then can set up nominal S_NOMIt is worth and (such as, receives on reverse link or from the storage device of such as memorizer 292 etc Read), by measuring interference in different resources, can specify that SNR value and calculate effective SNR Value.On the contrary, if S value can be accessed in the case of not accessing I value, then may determine that nominal I_NOM Value (such as, receive on reverse link or read from the storage device of such as memorizer 292 etc), And by measuring S, regulation uses the SNR value of nominal I value and is transformed into capacity generates effective SNR Value.OSI formation component 284 can perform to generate relevant latter acts to effective SNR.

It should be appreciated that any tolerance substantially can be used to calculate effective thresholding.Interference metric Can be relevant to other performance metric, such as signal-to-noise ratio, Signal to Interference plus Noise Ratio.These Performance metric can also derive the interference value that OSI formation component 284 can use, in order to judges whether Needs send excessive OSI.Can each of in the method for it is to be further understood that/process (1)-(4) To be more suitable for specific concept.Depend on and determine that the method (1) of average interference metrics may adapt to Following system, within the system, access terminal (such as, access terminal 220) is not having priori Or expect less than receiving aggregate resource in the case of distribution details (such as, bandwidth, modulation scheme) Distribution.In the case, as discussed above, meansigma methods can solve may become in distribution Change, be therefore suitably to select.Interference level measured by method (2) and method (3) monitoring The afterbody of distribution, both approaches is enough for maintaining the integrity controlling channel communication.Effectively Interference method (4) can be more suitable for ample resources distribution, the most such as to access terminal (example As, access terminal 220) distribute a large amount of subcarrier.In this scene, movement station can observe difference Some of the channel conditions of resource realize, and therefore can effectively determine middle benefit from interference level.

Being discussed as explained above with Fig. 2, access terminal 220 can receive on forward link 295 The excessively instruction of other sector interference.Additionally, access terminal (such as, 220) can (via long away from From or the FL channel of large coverage, the F-OSICH in such as 3G UMB；Refering to above) from One group of multiple non-serving access points of active set that this terminal obtains or be positioned at this active set obtained Outside AP receive OSI instruction.Additionally, as discussed in connection with figs 3 and 4, this instruction can With corresponding to OSI at a slow speed or corresponding to quick OSI.Then, Fig. 5 is used these to be discussed not With the mutual of instruction and they and interference and the relation of resource management, wherein Fig. 5 is for illustration purposes. Fig. 5 A and Fig. 5 B is Figure 50 0 and 550 respectively, and the two figure depicts deviant (Δ) and they are right Response in OSI instruction 503.

When the initial resource allocation for traffic channel transmission is on forward link (such as, FL 265) The access point (such as, AP 250) serviced by offer is passed to access terminal (such as, AT 220) After sending, just can preserve datum (such as, Fig. 5 A and the figure of institute's Resources allocation in this terminal R in 5B_REF506).Memorizer (such as, memorizer 232) can preserve this in storage medium Reference value.Can according to responding the offset Δ of OSI and quick OSI instruction at a slow speed to adjust this reference value, Thus manage the resource distribution of terminal.If it should be noted that, OSI instruction 503 comes from terminal (example Such as, AT 220) oneself transmit the interference generated, then this terminal may determine that and OSI is indicated 503 Respond, or terminal may determine that any to broadcasted by access point (such as, AP 280) Even if OSI instruction this instruction of 503(is corresponding with the time-frequency resources that this terminal does not uses) carry out Response.The time-frequency resources that can include that identification is corresponding with OSI instruction is determined additionally, described. Side-play amount can be used to adjust, in order to use favourable channel conditions (such as, high CQI) or access The available antenna of point.Therefore, terminal can also judge further with CQI and other available resources Whether adjust deviant, so that OSI instruction 503 to be responded.Δ 515 can be weighed with dB. In one aspect, Δ formation component 224 determines the size of deviant.It should be noted that, when being managed Communication resource when being power or power spectral density, access terminal institute in non-serving sector can be alleviated The interference level caused.Specifically, access terminal (such as, terminal 220) is by datum (such as, R_REF506) increase suitable offset value delta 515, itself and Traffic Channel (example can be calculated Such as, in 3G UMB, reverse data channel (R-DCH)) relevant transmitting power or power spectrum Degree.

In one aspect, access terminal (such as, AT 220) can only maintain a Δ value, this Δ value It is adjusted according to (or regular) OSI instruction 512 and quick OSI instruction 509 at a slow speed.Fig. 5 A Depict following scene: offset Δ 515 increases to offset Δ ' 521 by value d Δ 518.Or, Or additionally, access terminal (such as, AT 220) can keep two or more Δ values, comprising: one Individual slow OSI Delta value (uses Δ in figure 5b_S553 represent), wherein slow OSI Delta value can be according to fixed Phase OSI indicates (such as, ＜ I ＞^(slowly)512) it is adjusted；One or more fast OSI offset value ( Fig. 5 B uses Δ_F(1)-Δ_F(P)Represent), wherein one or more fast OSI offset value can be according to quickly OSI indicates (such as, ＜ I ＞^(soon)509) it is adjusted.In figure 5b, respectively with Δ '_S559 Hes Δ′_F(1)-Δ′_F(P)、562₁-562_PDescribe at a slow speed with quick-adjustsing deviant.It should be noted that, make In the case of carrying out adjustresources distribution by multiple deviants, institute's adjusted value of this resource is based on ＜ I ＞^(slowly)With 〈I〉^(soon)Combine and determine, wherein ＜ I ＞^(slowly)With ＜ I ＞^(soon)According in mean discussed above (1)-(4) At least one method determines.It should be appreciated that be maintained for more than a quick OSI Δ in terminal Value (such as, value 556₁-556_PWith 562₁-562_PIn the case of), each Δ_F(J)Can correspond to not Reverse link entangled object together, frame, distribution etc..Additionally, fast OSI offset value is this various Property is easy to hierarchical resource in these time intervals (such as, entangled object) (without in interference metric On significant change detected) in maintain its currency.It should be noted that, by for each son Carrier wave preserves deviant, it is also possible to further expand this species diversity (refering to Fig. 4).

Before proceeding to describe algorithms suitable for offset adjustment, it is noted that in order to prevent quickly OSI Δ adjusts (such as, value Δ_F(1)-Δ_F(P)) disturb resource management's (such as, merit based on regular delta Rate controls operation and interference mitigation), access terminal (such as, AT 220) can limit fast offset values Upper range limit be defined to slow OSI Delta value (such as, Δ_S).If transmission causes on physical channel Distorted signals causes loss and the intra-sector interference therefore of orthogonality, then resource management is (such as, Power control algorithm) may be incorporated into the requirement of the dynamic range to received signal, and limit partially Minima that shifting amount can use (in Fig. 5 A and Fig. 5 B, Δ_MIN, 524) and maximum (at Fig. 5 A With in Fig. 5 B, Δ_MAX, 527).Can be according to about from the serving sector (such as, 250) of access terminal The information of the interference level of broadcast, adjusts this minimum and maximum deviant.

About side-play amount adjust (for example, it may be judged whether performs adjustment (increase, reduce also be to maintain inclined Shifting value) and/or perform the amplitude (such as, d Δ 518) adjusted), access terminal (such as, AT 220) Two kinds of methods can be used: the most probabilistic and the most deterministic.For protecting in an access terminal Each deviant (such as, the Δ deposited_S553 and Δ_F(1)-Δ_F(P)556₁-556_P), can use arbitrary The method of kind.Situation (i) in, for simplicity rather than as limit, it is assumed that maintain list One deviant (Fig. 5 A), indicates (such as, ＜ I ＞ with quick OSI at a slow speed receiving^(slowly)512 and ＜ I ＞^(soon)509) After, access terminal is according to probability distribution P=P (Δ, ＜ I ＞^(slowly),〈I〉^(soon), rCQI), Δ formation component can be passed through 224 determine the amplitude and symbol (such as, d Δ 518) that deviant adjusts.Here, rCQI=CQI^(NSS)/CQI^(SS), (such as, terminal is made there to be used for indicating non-serving sector (NSS) Become other sector of interference) relative to (CQI of serving sector (SS) of this terminal (CQI) measured by) channel strength.Amplitude and the symbol of the d Δ 518 issued make to be adjusted Offset Δ '_S559 are positioned at by Δ_MIN524 and Δ_MAXAmong boundary given by 527.Or, d Δ The amplitude of 518 can previously be specified, and uses probability distribution P to determine and the most not to perform adjustment. It should be appreciated that in this probabilistic approach, access terminal can for the response that excessive OSI indicates The communication resource available to be to maintain (such as, not reducing).Due to this feature, probabilistic approach (i) being very suitable for the system of full load, OSI instruction is fluctuated around quasi-equilibrium value the most at a slow speed, and one The random response that a little wireless devices indicate for OSI averages out, thus through the communication resource Adjustment makes to disturb entire lowering.Processor (such as, processor 228) can include probability distribution also Issue the random value adjusted for side-play amount.In order to record and analyze system action, deviant and OSI Instruction can be saved in memorizer (such as, memorizer 232).

In case of deterministic approach (ii), access terminal (such as, 220) can use weight Function w=w (＜ I ＞^(slowly),〈I〉^(soon), rCQI) determined by algorithm, wherein this weighting function for for upwards or to The adjustment of lower side-play amount arranges the amplitude of specific discrete (stepping) value d Δ 518.It should be appreciated that This value can be determined by the processor (such as, processor 228) in access terminal.Such as method (i) Equally, in order to record and analyze system action, deviant and OSI instruction can be saved in memorizer (example As, memorizer 232 or 262) in.

Although it should be noted that, Δ formation component 224 can be for adjusting OSI and quick OSI at a slow speed Side-play amount uses Deterministic Methods (i), but adjusts for fast OSI offset and can avoid probability side Method is (ii).In one aspect, when receiving quick OSI instruction, in order to reduce in nearby sectors Interference, it is desirable for deterministically adjusting the communication resource.In a bursty situation, hierarchical resource is random Adjustment may cause the increase that bursty access terminal is interfered.For OSI at a slow speed and quick OSI Δ adjusts, and the access terminal (such as, AT 220) receiving excessive OSI instruction substantially can make apparatus There is the identical algorithms being substantially the same parameter set.Or, or additionally, access terminal can use difference Algorithm and/or different parameter sets adjust different Δ value (Δs_S553、Δ_F(1)-Δ_F(P)556₁-556_P). Giving one example, the parameter for the needs adjusted with Fast incremental at a slow speed is different, these parameters It is to rise or fall step size (such as, d Δ 518) and different decision threshold (such as, I_TH320).

In yet another aspect, Δ formation component 224 can use the value of slow OSI offset as quickly The upper limit of OSI side-play amount, it is inclined that it preserves in generating for access terminal (such as, AT 220) The adjustment of shifting amount, wherein this access terminal receives the instruction of excessive OSI.In yet another aspect, connect Entering terminal can use quick OSI instruction to adjust deviant.But, as discussed above, clothes Business access point (such as, AP250) can realize algorithm so that fast OSI Delta value is driven onto OSI Δ at a slow speed Value, this is because, only just generate fast OSI offset value also when bursty terminal is present in system And in access terminal to be saved it in.It should be noted that, in expansion time section (wherein at this Expansion time section does not has burst transfer) on keep fast OSI value, can to long OSI side-play amount really Surely adversely affect.Being explained in figure 6, Fig. 6 is Figure 60 0, in Figure 60 0, Such as Service Access Point 250 will be at time τ_UThe fast OSI Delta value Δ generated_F(U)610 are driven onto (dotted line 615) by time τ_L-1The slow OSI offset generated_S(L-1)Higher limit given by 620.Time Between τ_L, such as, generate new slow OSI offset by Δ formation component 224_S(L)625, and, Δ_F(U)It is driven to the slow offset that (dotted line 630) is newly determined again.Service Access Point can continue Drive fast offset Δ_F(U)610, until there is new burst transfer in systems and generating new quick Till OSI Δ value.

Performing side-play amount upon Δ formation component 224 to adjust, access terminal just can be by renewal Deviant (such as, the Δ ' in Δ ' the 521 and Fig. 5 B in Fig. 5 A_S559、Δ′_F(1)-Δ′_F(P)562₁-562_P) Recommended value as following resource distribution is transferred to its Service Access Point (such as, AP 250).

Those skilled in the art will appreciate that and it is realized that, can alternatively by method representation become such as A series of correlation behaviors in state diagram or event.

Fig. 7 gives the flow chart of the exemplary method 700 for generating OSI instruction, and wherein OSI refers to Show that for managing resource and interference in radio systems be required.In operation 710, based on interference metric Determine interference level.The tolerance selected can be the performance metric of such as signal-to-noise ratio etc. Determine that interference level relates to the interference on various time-frequency resources based on selected interference metric Level measurement.In one aspect, fast short-term assessment can be carried out and determine for a long time.All right For the son in the special time territory resource of such as specific frame (Fig. 3) and entangled object etc and frequency domain Carrier wave (Fig. 4), determines interference level.It is described that determine can be relevant to rapid evaluation.Lift an example Son, non-serving access points 280 can use the OSI being couple to processor (such as, processor 288) Formation component (such as, assembly 284), carries out described interference level and determines.Processor can aid in Realize the measurement of interference level, and effectively interference metric is (such as, average and based on power system capacity Interference level) calculating.Operation 720, according to determined by interference level generate OSI instruction. In one aspect, generate OSI instruction to relate to the effective interference level determined and wireless communication system The threshold interference level (Fig. 3 and Fig. 4) that service supplier is set up compares.In operation 730, Launch OSI instruction.In one aspect, non-serving access points (such as, AP 280) is at special forward direction OSI is transmitted to access terminal (such as, AT 220) on link (such as, FL 295) physical channel Instruction.This channel can be embodied in fast OSI control channel.

In yet another aspect, probability or deterministic algorithm is used can to realize the adjustment of Δ value.Access terminal (example Such as, access terminal 220) algorithm being substantially the same can be used to adjust and the instruction of OSI at a slow speed and soon The side-play amount that speed OSI instruction is relevant.
