Now referring to accompanying drawing, Fig. 1 is the explanation according to the wireless multiple-access communication system 100 of various aspects.In one example, wireless multiple-access communication system 100 comprises a plurality of base stations 110 and a plurality of terminal 120.In addition, one or more base stations 110 can communicate with one or more terminals 120.As nonrestrictive example, base station 110 can be access point, Node B and/or other suitable network entity.Each base station 110 provides communication to cover at specific geographic area 102a-c.As used herein and this area institute is normally used, and according to the employed context of term " sub-district ", term " sub-district " can refer to base station 110 and/or its overlay area 102.

In order to improve power system capacity, can will be divided into a plurality of with base station 110 corresponding overlay area 102a than zonule (for example, regional 104a, 104b and 104c).Each can be served by base station transceiver subsystem (BTS does not illustrate) separately than zonule 104a, 104b and 104c.As used herein and this area institute is normally used, and according to the employed context of term " sector ", term " sector " can refer to BTS and/or its overlay area.In one example, the sector 104 among the 102a of sub-district can be formed by the antenna sets (not shown) of base station 110, and wherein the terminal 120 be responsible in the part with sub-district 102 of each group antenna communicates.For example, the base station 110 of serving sub-district 102a can have with corresponding first antenna sets of sector 104a, with corresponding second antenna sets of sector 104b and with the corresponding third antenna group of sector 104c.But, should be understood that the disclosed various aspects of the application can be used in the system with sectorization and/or non-sectorized cells.In addition, it is to be further understood that sectorization with any amount and/or all suitable cordless communication networks of non-sectorized cells all fall within the protection range of appended claims.For simplicity, term as used herein " base station " can refer to the station of serving sector and the station of Serving cell.Further use as this paper institute, " service " access point is the access point that given terminal communicates with it, and " adjacent " access point is the access point that given terminal does not communicate with it.Though for simplicity, hereinafter description is relevant with a kind of system usually, and each terminal and a Service Access Point communicate in this system, should be understood that, terminal can communicate with the Service Access Point of any amount.

According to an aspect, terminal 120 can be scattered in the system 100.Each terminal 120 can be static or move.As non-limiting example, terminal 120 can be access terminal (AT), mobile radio station, subscriber equipment, subscriber station and/or other suitable network entity.Terminal 120 can be wireless device, cell phone, PDA(Personal Digital Assistant), radio modem, handheld device or other suitable equipment.In addition, terminal 120 can communicate or not communicate with base station 110 in the base station 110 of any given time and any amount.

In another example, system 100 can use centralized architecture by using system controller 130, and wherein system controller 130 can be connected to one or more base stations 110, and to coordinating and control in these base stations 110.According to substituting aspect, system controller 130 can be the set of single network entity or network entity.In addition, system 100 can use distributed architecture, so that allow base station 110 to communicate each other as required.In one example, system controller 130 can additionally cover one or more connections of a plurality of networks.These networks can comprise the internet, based on the network and/or the circuit-switched voice network of other grouping, these networks can to/from system 100 the terminal 120 that communicates of one or more base stations 110 provide/acquired information.In another example, system controller 130 can comprise the scheduler (not shown) or couple mutually with scheduler that wherein scheduler can be dispatched the transmission of going to and/or coming self terminal 120.Certainly, scheduler can be arranged in each independent sub-district 102, each sector 104 or its combination.

In one example, system 100 can use one or more multiple access schemes, for example CDMA, TDMA, FDMA, OFDMA, Single Carrier Frequency Division Multiple Access (SC-FDMA) and/or other suitable multiple access scheme.TDMA uses Time Division Multiplexing, wherein in this scheme, by launch the transmission of orthogonalization different terminals 120 in the different time intervals.FDMA uses frequency division multiplexing (FDM), wherein in this scheme, by launch the transmission of orthogonalization different terminals 120 in different frequency sub-carrier.In one example, TDMA and FDMA system can also use code division multiplexing (CDM), in CDM, promptly are used in the identical time interval of being transmitted in of a plurality of terminals or the frequency sub-carrier and send, also can use different orthogonal coding (for example, walsh codes) to come these transmission of orthogonalization.OFDMA uses OFDM (OFDM), and SC-FDMA uses single carrier frequency division multiplexing (SC-FDM).OFDM and SC-FDM system bandwidth can be divided into a plurality of quadratures subcarrier (for example, tone, frequency ...), these each subcarriers can be modulated with data.Generally speaking, adopt OFDM to send modulation symbol, adopt SC-FDM to send modulation symbol in time-domain in frequency domain.Additionally and/or alternatively, system bandwidth can be divided into one or more frequency carriers, each frequency carrier can comprise one or more subcarriers.System 100 can also use the combination of the multiple access scheme such as OFDMA and CDMA.Though the power control techniques that this paper provides should be understood that normally at the OFDMA system description technology described herein can be applied to any wireless communication system similarly.

In another example, base station 110 in the system 100 and terminal 120 can be used one or more data channel transmission data, use one or more control channel command transmittings.Can make and only use to the data channel of active terminal 120 distribution systems 100 uses by a terminal at each data channel of any given time.Perhaps, can be to a plurality of terminal 120 distribute data channels, wherein can be on a data channel superimposed or dispatch these terminals 120 orthogonally.In order to save system resource, can also use for example code division multiplexing shared system 100 employed control channels between a plurality of terminals 120.In one example, because the imperfection of channel conditions and receiver, so only frequency and in the time data channel (for example, not using the multiplexing data channel of CDM) of orthogonal multiplex compare with corresponding control channel, can less be subjected to the influence of loss of orthogonality.

According to an aspect, system 100 can use centralized dispatching by for example one or more schedulers in system controller 130 and/or 110 realizations of each base station.In the system that uses centralized dispatching, scheduler can rely on the feedback of self terminal 120, makes suitable scheduling decision.In one example, for make scheduler can estimate terminal 120 (wherein feedback receives from this terminal 120) thus supported reverse link peak rate and distribution system bandwidth, described feedback can comprise power amplifier (PA) headroom (Headroom) feedback.

According to another aspect, indication can be disturbed to terminal 120 broadcasting or emission in base station 110.In one example, base station 110 can be broadcasted other sector interference (OSI) message and/or whether just experienced corresponding other similar information of excessive interference with base station 110.Can broadcast these information by special-purpose OSI channel and/or other suitable channel.In case broadcasting, subsequently, terminal 120 just can use OSI message to adjust the employed resource of transmission on the reverse link.As specific example, these resources can comprise power spectral density (PSD) parameter, and the latter is based on the long-term average path loss difference between the difference between data channel PSD, the control channel PSD and serving BS 120 and the strongest one or more neighbor base station 120.In another specific example, system 100 can use return link interferences control, so that the minimum system of the system of assurance stability and service quality (QoS) parameter.Particularly, system 100 can use the wrong substrate of the decoding error probability acknowledge message of reverse link (RL) as all forward link transmissions.By using Interference Control on RL, system 100 can promote to control professional and/or have other professional power efficient transmission of strict wrong demand with QoS.

Fig. 2 A-2B is the operational block diagram of describing in the wireless communication system based on the example system 200 of the power control of increment.In one example, system 200 comprises terminal 210, and the latter can communicate with base station 220 on forward link and reverse link via one or more antennas 216 on the terminal 210 and the one or more antennas 222 on the base station 220.Should be understood that base station 220 can provide covering for the zone (for example, the sector 104) in sub-district (for example, the sub-district 102) or the sub-district.In addition, though for simplicity, only described a terminal 210 and base station 220 in system 200, system 200 can comprise the base station and/or the terminal of any amount.For example, system 200 can comprise one or more neighbor base stations, these base stations can provide covering for geographic area (wherein, these geographic areas can comprise All Ranges, the subregion that base station 220 covers or not comprise any zone that base station 220 covers) separately.

According to an aspect, terminal 210 and base station 220 can communicate by one or more power control techniques, so that terminal 210 employed amount of transmission power or other resource that control is communicated by letter with base station 220.In one example, terminal 210 can be adjusted assembly 212 by transmission, for carrying out local power control with communicating by letter of base station 220.Perhaps, can between terminal 210 and base station 220, carry out power control techniques collaboratively.Hereinafter will describe further can be by the example power control technology of terminal 210 and base station 220 execution.

According to another aspect, the power control techniques that the entity in the system 200 uses has additionally been considered the interference of existence in the system 200.For example, in multi-address radio communication system, a plurality of terminals 210 are multiplexed in time, frequency and/or encoding domain orthogonal by the transmission with them, can side by side carry out ul transmissions.But, from the complete quadrature between the transmission of different terminals 210 often because channel conditions, receiver is undesirable and other factors and can not realizing.As a result, the terminal in the system 200 210 often causes interference to other terminal 210 that communicates with common sector.In addition, generally speaking, because non-orthogonal each other from the transmission of the terminal 210 that communicates with different sectors, so each terminal 210 also can cause interference to the terminal 210 that communicates with near sector.As a result, the interference that causes of other terminal 210 in the system 200 has reduced the performance of terminal 210 in the system 200.

Therefore, the amount of the presence of intercell interference that causes of given terminal 210 can be determined with respect to the position of the nearby sectors in the system 200 by these terminal 210 employed transmitted power levels and this terminal 210.In view of the above, can in system 200, carry out power control, so that allow each terminal 210 in keeping the sub-district, under acceptable level range situation, to launch by suitable power level with presence of intercell interference.For example, can allow to be positioned at the terminal 210 that approaches its serving BS 220 and launch by higher power level, this is because this terminal may cause less interference for other base station in the system 200.On the contrary, the terminal 210 at 220 edge, overlay area may cause more large disturbance for neighbor base station away from the terminal 210 of base station 220 with in the base station owing to be positioned at, therefore with these terminal limitations at lower transmitted power level.By controlling transmitting power by this way, system 200 is allowing " titular " terminal 210 to realize can reducing the overall interference that base station 220 is observed under higher SNR and the higher data rate situation therefore.

For the overall performance of each entity in the increase system 200, can in system 200, use various technology to carry out based on the power control of disturbing.In a kind of this type of technology, for given terminal 210, the transmit power spectral density (PSD) that is used for data channel or other suitable channel (having the power offset based on one other channel) can be represented by formula (1):

P _dch(n)＝P _ref(n)+ΔP(n) (1)

Wherein, P _Dch(n) be at upgrading the emission PSD that is used for data channel of n at interval, P _Ref(n) be at the reference PSD level that upgrades interval n, Δ P (n) is at upgrading the emission PSD increment of n at interval.Can be that unit (for example, is used for P with the decibel _Dch(n) and P _Ref(n) dBm/Hz and the dB that is used for Δ P (n)) provide PSD level P _Dch(n) and P _Ref(n) and transmitting power increment Delta P (n), can certainly use other unit.In addition, should be understood that, can also use to be different from the calculating that provides by formula (1).In one example, with reference to PSD level P _Ref(n) with target signal to noise ratio (SNR) that need to realize given transmission but or the emission PSD of erasing type mistake (erasure) rate amount corresponding.This transmission can be provided by fixed channel, for example channel quality feedback channel or request channel.If but reference power level can realize corresponding target SNR or erasing type error rate, the SNR that receives of other channel can estimate by following formula so:

SNR _dch(n)＝SNR _t?arg?et+ΔP(n) (2)

In one example, the data channel that is used by the entity in the system 200 can have similar interference statistics amount with corresponding control channel.For example, when from the control of different sectors and data channel when interfering with each other, above-mentioned situation will take place.In the case, terminal 210 can calculate the interference offset amount of these channels.Perhaps, the interference offset amount between control channel and the data channel can be broadcasted by one or more base stations 220.

In another example, the emission PSD of data channel can be provided with based on following factor: for example, interference volume in the sector that the inter-sector interference amount that terminal 210 causes for other terminal in the nearby sectors (for example, the sector 104) just potentially, terminal 210 cause for other terminal in the common sector just potentially, the maximum of terminal 210 can allow time period and/or the other factors between the transmission of transmitted power level, terminal 210.

Referring to Fig. 2 A, this figure has described the transmission of the reverse link (RL) between the terminal 210 and base station 220 230 in the system 200.In one example, the resource that is used for rl transmission (for example, power and/or bandwidth) of terminal 210 uses can be adjusted by the transmission adjustment assembly 212 of terminal 210.In another example, assembly 212 is adjusted in transmission can adjust the resource that is used for rl transmission that terminal 212 is used by using one or more power control techniques (wherein these power control techniques are taken into account the interference and/or the other factors of a plurality of entity observations in the system 200).An example of transmission adjustment assembly 212 operable power control techniques is based on the power control techniques of increment, in this technology, can adjust the transmitting power of terminal 210 according to the increment deviant.As specific and non-limiting example, the increment deviant can be corresponding with transmitting power difference and/or any other suitable tolerance between terminal 210 employed pilot channels and the Traffic Channel.

According to an aspect, terminal 210 can also comprise feedback component 214, so that the information of on rl transmission, controlling to base station 220 through-put powers, thereby promote the collaboration power of terminal 210 to control.For example, feedback component 214 can be supported the subcarrier of current emission PSD increment or the maximum quantity N of wavelet band to emission PSD increment and terminal 210 that base station 220 transmission transmission adjustment assemblies 212 are calculated _{Sb, max}(n).In addition, feedback component 214 can also be to the service quality (QoS) and the buffer size parameter of base station 220 emission expectations.In order to reduce the quantity of expectation signaling, feedback component 214 can be launched Δ P (n) and N by a subclass of upgrading at interval by the in-band signalling on the data channel and/or by alternate manner _{Sb, max}(n).Should be understood that, with terminal 210 corresponding low emission PSD increments and do not mean that terminal 210 do not use its all available resources.As an alternative, in order to use all its available transmitting powers, can provide subcarriers that are used to transmit or wavelet band for terminal 210 more.In addition, feedback component 214 can be provided for the information of power control in many ways to base station 220.For example, can provide these information to base station 220 in the following manner: the mac header of grouping (for example, control channel grouping); In physical channel independently, for example be used to disturb channel with the power Control and Feedback; As the part of channel condition information feedback one or more bits of channel condition information (for example, as) and/or by other suitable mode.

According to another aspect, though it is very effective being controlled at the transmitting power of adjusting terminal 210 and controlling the interference volume that 220 places, base station cause in the system 200 between continuous transmission period based on the power of increment, can not provide initial set point for the transmitting power or the PSD of terminal 210.What be more suitable for is that in one section non-active period (or " quiet period ") afterwards, initial set-point can be the PSD value.If system 200 is partly loads, make that terminal 210 is the single bursty interference persons for nearby sectors, the increment size of terminal 210 then between the quiet period of terminal 210, do not bear any interference and do not launch the indication of other sector interference in a large number, so can increase to the maximal increment value during this period owing to nearby sectors.In the case, based on the power of increment control find the increment size of terminal 210 adjusted to the chance of proper level before, when burst transfer began each time, the burst transfer of terminal 210 all caused significant interference volume for nearby sectors.This can cause the packet error in the nearby sectors or lose the reverse link acknowledge message.Therefore, in one example, transmission adjust assembly 212 can be used for terminal 210 start burst begins each time the time adjust increment size.Initially adjust by the resource that terminal 210 is used to transmit use, transmission is adjusted assembly 212 and can be taken action, with restriction because the performance loss that a large amount of risings of interference cause.

In one example, terminal 210 can begin transmission with the Minimum Increment value between quiet period, and allows transmission to adjust the increment size that assembly 212 adjustment are used for subsequent transmission.But, in some instances, for example when terminal 210 when base station 220 emission has the burst service of little grouping, this causes being used for the unnecessary poor throughput of bursts of traffic.Perhaps, the interference volume when limiting that burst service begins each time, assembly 212 is adjusted in transmission can be for the maximum bandwidth value W of increment size and/or request _MaxCarry out the open loop adjustment.Mode by example, assembly 212 is adjusted in transmission can judge whether the previous transmission of terminal 210 is later than predetermined thresholding and takes place, but quantity and/or other tolerance that wherein predetermined thresholding can be measured based on the quantity erasing type mistake of a plurality of frames, superframe, time period, assignment messages.If be later than predetermined thresholding, then subsequently, transmission adjust assembly 212 can calculate the open loop increment size, based on the open loop increment size that is used for transfer bandwidth that is distributed, based on bandwidth and/or other parameter of the distribution that is used to transmit of increment size.After calculating suitable parameter, can adjust terminal 210 employed bandwidth and/or transmitting power according to these calculating.

In one example, for example, determining, transmission can adjusted assembly 212 and only be restricted to and to begin to carry out the open loop adjustment in burst each time by after the thresholding.Perhaps, assembly 212 is adjusted in transmission can be At All Other Times (for example, part with corresponding frame of the section of interweaving that does not have dispatch terminal 210 (Interlace) or frame) promotes the open loop adjustment, so that be provided for the maximum of quick increment size, thereby prevent owing to little OSI indicative of active makes the increment size Mrs that becomes.

The feedback shown in Fig. 2 A and/or the out of Memory that provide to base station 220 according to the feedback component 214 of terminal 210, shown in Fig. 2 B, base station 220 can generate the resource allocation 240 that is used for terminal 210 and distribute 240 to terminal 210 transfer resources.In one example, the transmitting power that is used for terminal 210 can be distributed by the power control assembly 224 of serving sector 220.Power control assembly 224 can receive feedback from the feedback component 214 of terminal 210, and other base station from terminal 210 and/or system 200 receives other parameter of disturbing indication and/or receiving the resource allocation that is used to generate terminal 210.The parameter that power control assembly 224 uses can be received together as common communication or receives in independent communication.In case power control assembly 224 has been determined resource allocation 240, described distribution just can be transmitted back terminal 210 by base station 220, and the transfer resource that assembly 212 can be used for terminal 210 according to described distribution adjustment is adjusted in the transmission on the terminal 210.

In a specific example, according to reference PSD level P _Ref(n), the signal power and/or the other factors that on reverse link channel quality index and/or request channel, receive from terminal 210, power control assembly 224 can calculate Δ P (n) and/or other parameter, to be used to generate the resource allocation 240 of terminal 210.In this example, determine the carrier-in-interference side-play amount by interference value being deducted thermal noise power recruitment (IoT-RoT).Subsequently, these values can be used to remedy in the reverse link channel quality index and/or ask to penetrate back terminal 210 from the signal power of terminal 210 receptions and/or as power control command transmitting on the channel.In one example, can according to disturb in the sector and sector that base station 220 is served in other terminal 210 determine the carrier-in-interference side-play amount.In addition, can calculate the IoT value at base station 220, and/or via receiving the IoT value from the broadcasting of other access point in the system 200 or sector and/or via backhaul from described access point or described sector.Additionally and/or alternatively, can calculate the RoT value by known power control assembly 224.In another example, the skew that power control assembly 224 uses can and/or depend on the increment factor of system based on stepping, other variation.

In another example, power control assembly 224 can be measured the whole interference powers that receive and use on the bandwidth of system 200 as Interference Control.All interference power can be used for determining maximum each user's jamming target, and subsequently, the latter can be used at rl transmission according to bandwidth, time and/or other parameter dispatch terminal 210.For example, can each user's jamming target be set to have the sub-fraction of whole interference powers of the system that is subject to disturb deployment.As nonrestrictive example, this target can be used in picocell deployment, this be because the cell edge in this deployment on each terminal have enough power overwhelm 5 or the 10MHz bandwidth on the sub-district.In addition, this target can be used in following sub-district, and these sub-districts are used to transmit the business with significantly low time delay, and this low time delay is subject to big IoT variable effect.

According to another aspect, 224 resource allocations 240 that receive with terminal 210 that determine of power control assembly may not be complementary with the open loop demand that is used for terminal 210 that transmission adjustment assembly 212 is calculated.For example, be worth corresponding maximum bandwidth according to adjusting the Minimum Increment that assembly 212 calculated with transmission, the bandwidth of being distributed may be excessive for terminal 210 is used.In the case, transmission adjustment assembly 212 can recovery from distribution does not match in every way.For example, transmitting adjustment assembly 212 can suspend transmission and miss the 220 reception distribution from the base station by indicating terminal 210.For another example, transmission is adjusted assembly 212 and can be used the Minimum Increment value to determine new maximum bandwidth and/or increment size, subsequently, and can be in order to receive new distribution to base station 220 these values of transmission.Additionally and/or alternatively, if terminal 210 can be carried out reverse rate indication (RRI) and/or the decoding of multiple hypothesis, so, in order to use resource allocation effectively, terminal 210 can change and is used for the packet format that communicates with base station 220.For an other example, assembly 212 is adjusted in transmission can abandon resource allocation, and at the distribution that abandons, indicating terminal 210 suspends transmission or mixing automatic repeat requests (HARQ) is provided.

Fig. 3 A-3B is the block diagram of operation of describing the example system 300 of power of reverse link control in the wireless communication system and interference management.In one example, system 300 comprises via antenna 316 and 322 terminals that communicate with serving sector 320 on forward direction and reverse link 310 separately.System 300 can also comprise one or more adjacent sectors 330 not direct and that terminal 310 communicates.For example, adjacent sectors 330 can be for providing adjacent geographic area, the zone boundary of covering that service is provided with serving sector 320.Though in system 300, only described a terminal 310 and two sectors 320 and 330, should be understood that system 300 can comprise the terminal and/or the sector of any amount.

According to an aspect, the resource that terminal 310 can use one or more power control algorithms based on increment to come control terminal 310 to use communicates with serving sector 320 on reverse link being used for.Terminal 310 can be used these technology independently, and perhaps alternatively, terminal 310 can be cooperated with serving sector 320 and be carried out based on the control of the power of increment.In one example, the power control techniques that uses of terminal 310 and serving sector 320 interference level that can cause based on the terminal 310 that serving sector 320 and/or other sector (for example, adjacent sectors 330) are located.Compare with the similar technique of not considering to disturb, these technology can promote that by using a factor of disturbing as in the power control of terminal 310 overall performance of system 300 is desirable more.

Referring to Fig. 3 A, this figure has described from terminal 310 to serving sector 320 rl transmission 314 and from follow-up other sector interference (OSI) indication 318 of nearby sectors 330.According to an aspect, if main interference sector 330 experience are come the subsequent interference of the rl transmission of self terminal 310, so main interference sector 330 can be via one or more antennas 332 on the forward link to the one or more OSI indications 318 of terminal 310 emissions.Terminal 310 can be used the OSI indication 318 that receives from main interference sector 330, so that determine the amount of the inter-sector interference that terminal 310 causes potentially in every way.In one example, the amount of the inter-sector interference that causes of terminal 310 can directly be estimated by other neighboring access point in main interference sector 330 and/or the system 300.Subsequently, can send the value of these direct estimation, so that make the terminal 310 can its transmitting power of corresponding adjustment to terminal 310.

Perhaps, the amount of the inter-sector interference that causes of terminal 310 can be carried out rough estimate according to following: the overall interference amount that main interference sector 330 and/or neighboring access point are observed; The channel gain of serving sector 320, main interference sector 330 and/or neighboring access point; And/or terminal 310 employed transmitted power levels.In one example, each access point in the system 300 can be estimated the interference volume of integral body or average current observation, and broadcasts these interferometries to be used by the terminal in other sector.As nonrestrictive example, each access point can use single other sector interference (OSI) bit that interfere information is provided.Therefore, each access point can be set to its OSI bit (OSIB) as follows:

Wherein, IOT _{Meas, m}(n) be by ratio (IOT) value of the measured interference of time interval n with thermal noise, IOT at m sector _TargetIt is the working point of this sector expectation.Employed as formula (3), IOT refers to an access the overall interference power of point observation and the ratio of thermal noise power.In view of the above, can select specific working point for system, and it is expressed as IOT _TargetIn one example, OSI can be quantified as a plurality of level and also therefore comprise a plurality of bits.For example, the OSI indication can have two level, as IOT _MINAnd IOT _MAXCan dispose these level, if make the IOT that for example observes between IOT _MINAnd IOT _MAXBetween, terminal 310 can continue to use its current transmitting power and need not adjust so.Perhaps, if the IOT of observation is higher than or is lower than given level, can correspondingly adjust transmitting power up or down so.

Main interference sector can transmit OSI indication 318 in every way.For example, the OSI indication 318 by main interference sector 330 transmission can be the regular OSI indication of carrying on forward link physical channel (for example, forward link OSI channel (F-OSICH)).OSI indication regularly can be rate-constrained in, for example the power that needs at these indications and the temporal frequency resource, each superframe transmissions is once.For another example, the OSI indication of being transmitted by main interference sector 330 318 can be the quick OSI indication of carrying on the quick OSI channel of forward link (F-FOSICH) and/or other suitable channel.For example, in order to carry out the how dynamic control of power level, these indications can be used in the scene of terminal 310 emission burst services.In addition, the OSI indication 318 of main interference sector 330 transmission can comprise other interference offset parameter that traffic interference and the indication and/or the main interference sector 330 of the ratio (IOT) of thermal noise power are observed, and wherein these parameters can be carried on the forward link physical channel such as forward link IOT channel (F-IOTCH).

According to another aspect, terminal 310 can additionally estimate to receive from terminal 310 channel gain or the propagation path gain of the access point of rl transmission 314.By handling the pilot tone that receives from each access point on the forward link, can estimate the channel gain of these access points.In one example, channel gain ratio between serving sector 320 and the neighboring access point such as main interference sector 330 can be used as " relative distance " and uses, and wherein " relative distance " shows that the distance of main interference sector 330 is with respect to the distance to serving sector 320.Can observedly be, along with terminal 310 moves towards the sector-edge corresponding to serving sector 320, the channel gain of neighboring access point will reduce than usually, and along with terminal 310 moves to the direction near serving sector 320, this value will increase usually.In addition, sector 320 and/or 330 can be transmitted about information and/or other channel quality parameter of pilot frequency carrier wave power with the ratio (pCoT) of thermal noise power to terminal 310 by forward link pilot quality index channel (F-PQICH) and/or other suitable forward link physical channel.

According to there being the OSI indication as shown in Figure 3A (interference that its indication is caused in the rl transmission to serving sector 320 by terminal 310) that does not still exist from main interference sector 330, terminal 310 can be carried out adjustment based on increment for the resource that rl transmission is used, and uses the resource of the adjustment shown in Fig. 3 B to repeat transmission.In one example, terminal 310 can comprise transmission adjustment assembly 312, with the resource that is used to adjust transmitting power, bandwidth and/or carry out the reverse link communication use with serving sector 320.Adjust the assembly that assembly 312 is depicted terminal 310 as though in Fig. 3 B, will transmit, but should be understood that serving sector 320 and/or other suitable network entity also can be independently or carried out transmission collaboratively with terminal 310 and adjust in the performed calculating of assembly 312 some or all.

According to an aspect, the OSI bit of the neighboring access point broadcasting of terminal 310 in can supervisory control system 300, and can be used for only responding the OSI bit of main interference sector 330, wherein main interference sector 330 has minimum in neighboring access point channel gain ratio.In one example, if since for example main interference sector 330 observe with nominal sector between disturb and compare higher interference, the OSI bit of main interference sector 330 is set to ' 1 ', so, assembly 312 is adjusted in transmission can correspondingly adjust the reverse link transmission resource that terminal 310 is used downwards, and indication is launched nearest rl transmission again to serving sector 320.On the contrary, if the OSI bit of main interference sector 330 is set to ' 0 ', the reverse link transmission resource that assembly 312 can adjust upward terminal 310 is adjusted in transmission so.Perhaps, transmission is adjusted assembly 312 and can be used from the OSI bit that surpasses an access point, uses various algorithms to adjust the reverse link transmission resource of terminal 310 and starts rl transmission 324 according to the OSI bit of a plurality of receptions.

According to another aspect, according to the quick OSI indication that receives from main interference sector 330, use transmission to adjust the power measurement that assembly 312 is calculated, assembly 312 is adjusted in transmission can adjust reverse link transmission power and/or other resource that terminal 310 is used.For example, if the transmitted in packets of terminal 310 causes the interference of main interference sector 330, so main interference sector 330 can reduce the transmitting power of transmission again that is used for this grouping to terminal 310 indications.As shown in Figure 3A, this can be for example by will going to terminal 310 the OSI indication with indicate relevant transmitted in packets to interweave with this OSI to realize.

Terminal 310 in (indicating based on the OSI from main interference sector 330) system 300 can be proceeded shown in time shaft among Fig. 4 400 in the transmission packets of carrying out on the reverse link, adjustment and follow-up transmission again.According to an aspect, after receiving the OSI indication, before transmission caused the grouping of OSI again, transmission was adjusted assembly 312 and can be adjusted terminal 310 employed resources.For example, shown in time shaft 400, can in the section of interweaving 401, carry out first rl transmission, so, in the section of interweaving 403, receive with this and transmit corresponding OSI indication.According to the OSI indication, in the section of interweaving 404, can carry out the resource adjustment, to be used for transmitting first grouping again in the section of interweaving 410.Equally, can in the section of interweaving 402, carry out second rl transmission, then,, in the section of interweaving 408, can carry out the second resource adjustment according to indicating of in the section of interweaving 405, receiving with the corresponding OSI of second transmission.The 3rd rl transmission as the section of interweaving 405 places is illustrated, can also be used for receiving the OSI indication on the public interleaving section of rl transmission.Pointed as the section of interweaving 407, can also receive the OSI indication that is used for the 3rd transmission.Shown in the section of interweaving in the time shaft 401 and 410, the transmission again of given grouping can eight sections of interweaving after initial transmission take place, and perhaps, transmission can take place in any other the suitable unification of following initial transmission or one time interval of the Organization of African Unity again.

In one example, whether cause the OSI indication and require adjustment, can determine to transmit again the transmitting power of grouping by judging original transmitted.If then terminal 310 can be checked other adjustment of making in the section of interweaving of predetermined quantity, the minimum adjustment performance number that causes the OSI indication that selection is noticed, and use the downward stepping of increment deviant to adjust this lowest power value.Perhaps, do not cause the OSI indication if determine original transmitted, terminal 310 can be checked other adjustment of making in the section of interweaving of predetermined quantity so, selection is noticed does not cause the highest adjustment performance number of OSI indication, and uses the increment deviant stepping that makes progress to adjust this peak power value.In another example, can use one or more technology described below to pre-determine or calculate increment size and/or the power measurement that is used to adjust transfer resource.

In another example, can during any section of interweaving of time shaft 400, come from other suitable entity in serving sector 320 and/or the system 300 at the new distribution of the transfer resource of terminal 310.New distribution can comprise, for example, provides the increment size of PSD according to the adjustment of the section of interweaving before.According to new distribution, terminal 310 can so that adjust transfer resource when subsequent reverse link transmission begins, thereby allow serving sector 320 to use this power measurement in the new distribution of terminal 310 to the power measurement of serving sector 320 reporting terminals 310 uses.In one example, if serving sector 320 determines that according to the report that comes self terminal 310 OSI exists, serving sector 320 can be turned down the transmitting power stepping of terminal 310 uses in follow-up distribution so.

Referring to Fig. 5-7, in these figure, described in the wireless communication system based on the power control of increment and the method for interference management.Though in order to make explanation simpler, and these methods are illustrated and are described as a series of action, but should be appreciated that and understand be, these methods are the order of limit movement not, because, according to one or more embodiment, some actions can by different order take place and/or with shown in the application and other action of describing take place simultaneously.For example, it should be understood by one skilled in the art that and understand that a method also can be expressed as a series of state and incidents of being mutually related, as in state diagram.In addition, the method for carrying out according to one or more embodiment is not to need the action shown in all.

Referring to Fig. 5, this figure has described to be used for adjusting the method 500 of reverse link transmission resource in wireless communication system (for example, system 200).Should be understood that method 500 can be carried out by for example terminal (for example, terminal 210) and/or any other suitable network entity.Method 500 starts from module 502, at first carries out rl transmission to serving sector (for example, the base station 220).Then, in module 504, judge whether the rl transmission in that module 502 is carried out takes place after predetermined thresholding.This thresholding can based on, for example: but a plurality of frame or superframe, time period, a plurality of assignment messages, a plurality of erasing type mistake measured value and/or other tolerance.

If judge after the transmission that module 502 is carried out does not occur in described thresholding in module 504, method 500 finishes so.Otherwise method 500 forwards module 506 to, in module 506, calculates the open loop increment size, based on the open loop increment size and one or more based in the bandwidth of increment size of bandwidth distribution.In one example, the open loop adjustment of carrying out in module 506 can be subject to the place that begins in transmitting burst separately, for example after the thresholding that uses in surpassing module 504.Perhaps, for the maximum of determining quick increment size to prevent becoming too big owing to little OSI indicative of active makes increment size, in module 506, can be used for calculating open loop projection on the section of interweaving of the entity of manner of execution 500 in scheduling not.

According to an aspect, calculating in module 506 execution, promptly calculate the open loop increment size, based on the open loop increment size that is used for transfer bandwidth that distributes and/or based on the transfer bandwidth that is used for of the distribution of increment size, can as non-limiting example hereinafter is described, carry out.In one example, in order to calculate the open loop increment sizes so that control maximum PSD recruitment, can calculate increment and make and satisfy following formula in module 506:

(IoT _avg+pCoT×Δ)/IoT _avg<IoTRise _max (4)

As employed in formula (2), IoT _AvgBe to can be used as the interference offset value that system parameters provides; For example, its can be broadcasted by non-serving sector can be from having the sector of minimum channel gain inequality with serving sector to be used for calculating open loop adjustment and/or its in module 506.In one example, for the simplified system design and/or in order to reduce the feedback quantity that power control needs, can be with IoT _AvgBe set to fixed value.In this example, can be with IoT _AvgBe set to conservative value (for example, 1, thereby suppose the current not interference except that thermal noise), such as IoT _TargetAnd so on nominal IoT value and/or other suitable value.In addition, the reference channel at pCoT and non-serving sector place (for example, reverse link pilot channel, cqi channel and/or any other reference channel) on the measured value (carrier wave PSD that for example, is received and the ratio of thermal noise PSD) of the signal power that received corresponding.The value of pCoT can be at the dedicated forward link channel (for example, forward link pilot quality channel (F-PQICH)) goes up transmission, the value of pCoT is transmitted from non-serving sector, and the value of pCoT is suitably adjusted the relevant parameter of serving sector by use channel gain difference and/or obtained by alternate manner.In addition, IoTRise _MaxThe maximum of indication in any interference volume that causes that accesses terminal at non-serving sector place can allow recruitment.IoTRise _MaxValue can be system configuration or the overhead value that provides.

In another example, if the increment size that uses technique computes above is less than Minimum Increment value (Δ _Min), can distribute maximum can support bandwidth W by predetermined amount or according to following formula so _Max:

(IoT _avg+W _max/W _tot×pCoT×Δ _min)/IoT _avg<IoTRise _max (5)

Wherein, W _TotIt is the total system bandwidth.

In other example, can be calculated as follows the open loop increment so that control mean P SD recruitment according to the bandwidth W that distributes in module 506:

(IoT _avg+W/W _tot×pCoT×Δ)/IoT _avg<IoTRise _max (6)

In addition, can also be according to Minimum Increment value (Δ _Min) calculate maximum and can support bandwidth W _Max, the out of Memory as helping service sector distribution W makes:

(IoT _avg+W _max/W _tot×pCoT×Δ _min)/IoT _avg<IoTRise _max (7)

And before distributing, transmit these information to serving sector.

In another example, can also can support bandwidth and control mean P SD recruitment based on the initial maximum of current increment size by restriction in module 506, the interference volume when controlling each burst transfer and beginning.In the case, maximum can be calculated and bandwidth (W can be supported _Max) value, make and satisfy:

(IoT _avg+W _max/W _tot×pCoT×Δ)/IoT _avg<IoTRise _max (8)

And transmit this value to Service Access Point.Subsequently, Service Access Point is mixed at follow-up branch can little by little increase the bandwidth of being distributed, so that have sufficient time to adjust increment size at quick OSI indication.

According to another aspect, when the entity of manner of execution 500 used corresponding increment size, serving sector can use data carrier to disturb (DataCtoI) value to be used for the entity Resources allocation to manner of execution 500.In addition, each packet format can have relevant DataCtoI _MinAnd Δ _MinValue.In one example, can keep and comprise the DataCtoI that will use _MinTracing table.In addition, can provide the index of tracing table for each packet format in module 506, so that allow the entity of manner of execution 500 and/or the DataCtoI of serving sector and this packet format _MinValue and/or Δ _MinCarry out association.

After module 506 was finished these calculating, method 500 finished in module 508, wherein in module 508, came (for example, adjusting assembly 312 by transmitting) to adjust bandwidth and/or transmitting power according to the result of calculation of carrying out in module 506 at least in part.According to an aspect,, can calculate first increment size (for example, Δ in module 506 according to the indication of OSI at a slow speed from contiguous access point _Slow).This first increment size can send it back serving sector to be used for following resource allocation as the maximum of other parameter of calculating in module 506 and/or as feedback or in conjunction with power space, jamming report and/or other feedback individually.In one example, can also additionally calculate second increment size (for example, Δ in module 506 _Tx), this second increment size can be used for adjusting in 508 pairs of transmitting powers of module and/or bandwidth.

According to another aspect, can be according to Δ _TxValue carry out the resource adjustment of module 508, as follows.At first, for each section of interweaving i, can be with power measurement PM _iBe defined as from the product of serving sector CoT value that receives and the bandwidth of distributing in this section of interweaving, for example, PM _i=CoT _i* BW _iSubsequently, calculate minimum and maximum power measurement according to following formula at each section of interweaving:

(9)

According to these values, subsequently can be by the power measurement of the following formula setting section of interweaving i:

Satisfy following restriction:

Δ _{Min, i}≤ Δ _{Tx, i}≤ Δ _{Distribute i}(11)

Additionally and/or alternatively, according to distribution from serving sector, according to following formula can module 508 adjust physical channels (for example, the emission PSD that uses of the Reverse link data communication on R-DCH):

PSD _R-DCH＝PSD _R-PICH+Δ _tx+AttemptBoost _j (12)

Wherein, j is sub-packet index, AttemptBoost _jIt is the power ascension parameter that serving sector distributes.

According to another aspect, the employed data channel in each sector in can multiplex system 300 makes their quadratures each other.But, even now multiplexing, but former carrying on as before of inter-carrier interference (ICI), intersymbol interference (ISI) and/or other can cause some losses in the orthogonality, cause thus disturbing in the sector.Disturb in order to alleviate in the sector, the emission PSD that assembly 312 can control terminal 310 is adjusted in transmission, makes that interference volume maintains within the acceptable scope in the sector that terminal 310 causes for other terminal in the common sector.This can for example, launch PSD increment Delta P (n) at respective range Δ P (n) ∈ [Δ P by restriction by following realization _Min, Δ P _Max] in, wherein, Δ P _MinWith Δ P _MaxBe respectively minimum and the emission maximum PSD increment that can be used for given data channel.

Fig. 6 has described to be used to adjust reverse link transmission resource so that reduce the method 600 of the interference in the wireless communication system (for example, system 300).Should be understood that method 600 can be carried out by any other the suitable network entity in for example terminal (for example, terminal 310) and/or the wireless communication system.Method 600 starts from module 602, at first carries out rl transmission to serving sector (for example, serving sector 320).Then, in module 604, judge whether that (for example, from main interference sector 300) receives the OSI indication.In one example, if the transmitted in packets of the entity of manner of execution 600 causes interference in nearby sectors, so this sector can launch OSI indicate ask to reduce be used for follow-up again the transmission transmitting power.This can realize by for example in module 602 the OSI indication being interweaved with transmission.

If receive OSI indication in module 604, method 600 forwards module 606 to so, in module 606, is chosen in and causes the employed lowest transmit power of OSI in the predetermined amount of time.In one example, the entity of manner of execution 600 can check in the section of interweaving of predetermined quantity or make in another preset time section other adjust, and select the minimum of the adjustment performance number that causes the OSI indication noticed.Subsequently, method 600 finishes in module 608, in module 608, adjusts transmitting power (transmitting power of transmission again that for example, is used for the transmission that module 602 carries out) by deducting the increment deviant in module 606 selected transmitting powers.
