Fig. 4 has explained orally the whole bag of tricks system according to the various aspects of given subject content.Although explain simplification with these method systems diagrams and be described as a series of actions or sequence step for making; but be to be understood that and understand; the order that subject content required for protection is not moved is limit, because some actions can be by being different from that the order that illustrates and describe occurs herein and/or occuring concomitantly with other actions.For example, it will be appreciated by those skilled in the art that and understand, method system can be expressed as a series of state or events of being mutually related with being replaced, such as in state diagram like that.Moreover, the not all action that has explained orally all be realize according to the method system of subject content required for protection necessary.Should further be appreciated that in addition hereinafter and run through the disclosed method system of this specification and can be stored on the goods in order to computer is carried and passed to this type of method system.Be intended to contain can be from the computer program of any computer readable device, carrier or medium access for term " goods " as used herein.

Fig. 4 is the functional block diagram 400 that explains orally according to an aspect of the present disclosure performed example frame when carrying out radio communication.At frame 402, UE can monitor that non-service B node (for example, all neighbours B nodes) obtains the broadcasts load indications bit.In one aspect, this UE can be from B node receipt message.At one aspect this type of, this message can be system information.In one aspect, this load designator can usually be broadcasted as 1 bit-cell in each subframe by one or more non-each of serving the B node.On the other hand, can this 1 bit elements be included in each subframe by midamble displacement appointment is applied the phase in-migration.Aspect this type of, this load designator can be indicated as " On(opens) " when the phase shift that applies is opposite with the phase shift of shared control channel, and this load designator can be indicated as " Off(pass) " when the phase shift that applies is identical with the phase shift of shared control channel.In one aspect, uplink load indication can be used at this UE place computational load percentage.This type of percentage can be used to upgrade the SNPL metric calculation.

At frame 404 places, the load factor of each non-service B node can be determined.In one aspect, this load factor can be calculated as therein the percentage of the time slot that receives " on " load indication.What on the other hand, load factor can be calculated as that time interval in definition receives receives the ratio of broadcasting with all broadcasting of " on " load indication through weighted average and total.

At frame 406 places, SNPL tolerance is determined.In one aspect, can determine that this SNPL measures by each the inverse of mediation summation of ratio of the loss of calculation services B node path and this one or more non-service B node path loss.On the other hand, can measure by this SNPL that recently determines that calculates this service B node path loss and the minimum value of this one or more non-service B node path loss.

In frame 408, can generate through weighting SNPL by this load factor being applied to this non-weighting SNPL.In other words, this load factor can be applied to the current SNPL that calculates, and this current SNPL that calculates can be based on the path loss to service and neighbours' cellular cell.Thus, this load factor can be used as weighted factor.This weighted factor can use in calculating with as percentage load (for example, load factor) is for example acted on SNPL(, path loss) function of tolerance with generation through weighting SNPL.In one aspect, this function can comprise this SNPL divided by this load factor.For example, the assumed load indicator bit is illustrated in to be had 80% for Binary Zero (for example, non-loaded) and has 20% for binary one (for example, load being arranged) lasting of the observation of nearest adjacent cellular cell 624, and then the load factor that obtains of result can be 0.2.In one example, through weighting SNPL value can then be calculated as this nominal SNPL value in linear domain divided by this load factor.

In frame 410, this can be transmitted to service B node through weighting SNPL value and other values.In one aspect, additionally or randomly, in frame 412, this load factor can be transmitted to this B node.Aspect examples of such optional, this UE also can will report to the B node as the added bit in the request message to the binary system "or" of getting from the load indication bit of all concentrated cellular cells of its virtual active.Further, aspect this type of, the binary system "or" that this UE also can get the load indication bit that its virtual active is concentrated directly offers service B node with the auxiliary scheduling decision that carries out as feedback.The path loss that this virtual active set can be defined as this UE drops on certain threshold level with the set of interior B node.In frame 414, this UE can receive resource from this B node and distribute.In one aspect, this resource is distributed the UE minimum interference that can be assigned to make by in the zoning of the non-service of high capacity B node service.On the other hand, this resource distribution can be assigned to make the data transfer rate maximization that is positioned at by near the UE the zoning of the non-service B node service with low load.Therefore, this B node scheduling device can allow UE to transmit with the data transfer rate higher than its data transfer rate that will reach with other modes.

Forward now Fig. 5 to, explained orally the call-flow for the example system 500 of facilitating resource to distribute.Generally speaking, UE 502 can communicate by letter with network 504.In one aspect, the high-speed uplink ability has been arranged, given UE 502 just can be according to transmitting with High Data Rate via the appointment of granting from the scheduling of B node scheduling device 504.As used herein, network 504 can comprise one or more B node, one or more RNC etc.

Turn back to Fig. 5, at sequence step 506 places, UE 502 can transmit the permission request message.In one aspect, when initiating, this message can comprise the request to B node 504, comprises information about its power headroom, buffer sizes and streaming quality (QoS) class to access at random uplink control channel (E-RUCCH) in enhancement mode.Additionally, UE 502 can monitor various channels, such as enhancement mode absolute grant channel (E-AGCH).At sequence step 508 places, B node 504 can receive this request and can make resource and grant decision-making, and this resource with enhancement mode physical uplink link channel (E-PUCH) (is for example granted decision-making, data channel) and enhancement mode mixed automatic repeat request indicating channel (E-HICH) the down link ACK of uplink traffic H-ARQ process (for example, be used for) distributes and the payload capacity that allows and the form of modulation format convey to UE 502.At sequence step 510 places, this permission can be transmitted to UE 502.At sequence step 512 places, UE 502 can process the permission of receiving and can grant to proceed transfer of data according to this, and further can proceed this request/permission process at sequence step 514 places, wherein this request can be via embedding with the multiplexing enhanced uplink control channel (E-UCCH) together of up link HSUPA traffic transmission.At sequence step 516 places, the uplink control information that is associated with enhancement type special channel (E-DCH) (for example, E-UCCH) can be received and can calculate acknowledgement in response to this.At sequence step 518 places, this acknowledgement can be transmitted to UE 502.

Referring now to Fig. 6, provided the diagram that conceptually explains orally example wireless communications 600.System 600 can comprise a plurality of B nodes (602,612,622), and wherein each B node is respectively zoning (for example, the cellular cell) service such as zoning 604,614 and 624.In one aspect, service B node 602 can be a plurality of UE(606,608) service.In order to realize spectral efficient, as long as can dispatching UE, service B node 602 transmits to guarantee to have data to transmit for the UE in this cellular cell, uplink thermal noise lifting (RoT) (or equivalently, goal systems load) just can be filled into certain threshold level and run through each network operation and remain stable.Additionally, thus B node scheduling decision-making given UE can be included in the potential interference that its all neighbours produce and consider the impact that reduces the RoT of one or more adjacent cellular cell.

In one aspect, service B node can be by attempting to make to the minimum interference of the adjacent cellular cell (for example, 612) that experiences high load condition and/or the maximized mode of data transfer rate that is positioned at the UE of the unimportant part of interference of adjacent cellular cell being come to all UE(606,608) Resources allocation.UE can be positioned near the service B node aspect this type of at one, and thus neighbours' cellular cell to disturb be not the problem that will worry.On the other hand, UE can be positioned at by being not to experience near the cellular cell 624 of B node 622 service of high capacity.Aspect this type of, this service B node can distribute High Data Rate more and the worry that needn't disturb relevant for other cellular cells 624 to UE 608.

In one aspect, in system 600, it is approximate, as follows that average uplink cellular cell throughput can use formula (1):

$\mathrm{KR}=\frac{W({\mathrm{\η}}_{\mathrm{UL}}-\mathrm{\α})}{(1+f)\×\frac{E_b}{N_t}}---\left(1\right)$

Wherein α indicates uplink overhead, η _ULBe marked with line link system load target (usually being arranged on 0.75 to 0.8), W indicates the system bandwidth in Hz, Eb/Nt unlabeled data channel link efficient, and K indicates the number of the UE in this system, R indicates every UE average throughput, and f indicates other cellular cell interference factors.In order to realize efficient throughput everywhere in whole system 600, the thermal noise lifting (RoT) that makes all cellular cells is filled and this other cellular cell interference factor f in the network is minimized can be useful.Making the minimized effective mechanism of f can be to reduce transmitting power and reduce by this cellular cell edge UE(606,608) the transient data rate.

In an example system 600 such as time division high speed uplink packet (TD-HSUPA) system, each UE(606,608) can be periodically to measurement SNPL corresponding to service B node 602 reports.Transmitting power (the P of service cellular cell 604 _Ref) and each frequency in the transmitting power (for example, measured from P-CCPCH) of neighbours' cellular cell (614,624) can consist of monitored neighbours' cellular cell tabulation and can be notified to UE so that this UE can estimate the average path loss (L of this service cellular cell by high-level signaling more _Serv) and the average path loss (L of this N neighbours' cellular cell in this monitored neighbours' cellular cell tabulation ₁, L ₂... L _N).Further, this UE can be configured to determine SNPL tolerance with the various report type.This SNPL tolerance is a kind of mode that is used to indicate the interference volume that potential UE can introduce to adjacent cellular cell.For example, Report Type 1 can use formula (2) to generate this SNPL tolerance, and Report Type 2 can use formula (3) to generate this SNPL tolerance, and is as follows.

$\mathrm{\Φ}=\frac{1}{\underset{n=1}{\overset{N}{\mathrm{\Σ}}}{L}_{\mathrm{serv}}/L_n}---\left(2\right)$

$=\frac{\underset{n=1..N}{\min }\left(L_n\right)}{L_{\mathrm{serv}}}---\left(3\right)$

As above various as described in, this SNPL can be calculated as each the inverse of mediation summation of ratio of all neighbours' cellular cell path loss of UE service cellular cell path loss and this UE, wherein these neighbours' cellular cells are neighbours' cellular cells (formula (2)) that the neighbours at this UE concentrate, be calculated as the ratio (formula (3)) of this UE service cellular cell path loss and the minimum value of all neighbours' cellular cell path loss of this UE, etc.In other words, this SNPL has many measuring near its adjacent cellular cell for given UE.Thus, B node scheduling device can be processed less SNPL tolerance to the lower data transfer rate of this UE appointment so that this UE transmitting power minimizes and make thus the minimum interference to other cellular cells.

Generally speaking, the SNPL feedback can comprise all the potential cellular cells among its neighbours in this feedback.Further, can the load of all adjacent cellular cells not included based on the indication of SNPL in to consider and feed back can be band internal feedback via long process, this type of long process can not be filled RoT in the short-term scale effectively.Thus, this normal SPNL feedback can cause that uplink throughput loss unnecessary in the system of fractional load is arranged.For example, in the situation that the cellular cell of fractional load (for example, 602) are arranged, when the adjacent cellular cell of one (or all) has very light load (624), in the situation of disposing at focus, by reporting low SNPL value, UE may exceedingly limit the transmission data rate of oneself.Aspect this type of, UE more High Data Rate transmits and does not have the risk that other cellular cells is caused interference, because the load of these other cellular cells is very light.In one aspect, every cellular cell load designator bit (for example, each subframe send, this given cellular cell of indication loaded 1 bit information whether) can be added in the B node broadcasts.This type of load designator can allow the B node to pass on the current cellular cell load measure to current subframe whether to surpass load threshold.This information has been arranged, and this UE just can feed back effectively (for example, through weighting) SNPL.This type of effective SNPL can be coupled to generate through the weight path loss from nominal SNPL and every cellular cell.Weighting can be depending on this UE indicates each cellular cell of learning from this load load.In one aspect, weighted function can be to transmit the proportional zoom that the percentage of time of high capacity designator carries out by given cellular cell.

In one aspect, each B node can be at time slot 0(TS0) during transmit this load indication.Generally speaking, in the TD-SCDMA system, TS0 is used to transmit to UE and comprises main control physical channel (P-CCPCH) and the secondary downlink overhead information that shares control physical channel (S-CCPCH) of sharing, and wherein each expense takies for the given Walsh dimension of transfer of data and has the given midamble of the individual default midamble code as pilot tone of K=8.This load indication bit can be in predetermined midamble displacement (for example, 8 one or more persons that possible midamble displacement is assigned) the upper transmission, and the value of this bit can be reflected in the phase place of this predetermined midamble for the phase place of the midamble that is used for P-CCPCH.For example, the Binary Zero that is used for this load designator can be from the phase place of appointment midamble and identical the obtaining of phase place of P-CCPCH midamble, and can obtain from the phase place of appointment midamble and the single spin-echo of P-CCPCH midamble for the binary one of this load designator.And, in each cellular cell, have aspect one that a plurality of carrier waves will support, the time of the carrier load information delivery that each carries out via the TS0 of main carrier can be based on the SFN(System Frame Number) and carrier number.Aspect this type of, can be to guarantee that by UE the adjacent cellular cell load information of its work carrier wave is up-to-date.

In an exemplary operation, suppose UE 608 service cellular cell path loss=X, and hithermost non-service cellular cell 624 path losses are than the high 3dB of X.Suppose type 2 feedbacks, the original SNPL value that then is called nominal SNPL is 3dB.Further, the assumed load indicator bit the observation to this hithermost adjacent cellular cell 624 last illustrated 80% for Binary Zero (for example, non-loaded) and have 20% for binary one (for example, load being arranged), then the load factor that obtains of result can be 0.2.In one example, effectively then the SNPL value can be calculated as this nominal SNPL value divided by this load factor (in linear domain).Continue above example, this UE can feed back effective SNPL of 3+4.7dB=7.7dB.In this way, this B node scheduling device just can allow this UE to transmit (for example, more than the twice of this data transfer rate) with the data transfer rate than the potential surplus of the high 4dB residual quantity of its data transfer rate that otherwise will reach.

Further again, in one aspect, in order to further expand the application of this 1 bit load indication, UE also can feed back load indication that it receives via request message, allows by this B node to make scheduling decision immediately and realizes higher UL spectrum efficiency.Request message also can comprise information such as normal SNPL, UE power headroom, UE data queue buffer size, data QoS class.Further, this request message can be embedded among UCCH or the RUCCH.This load indication can comprise the load indication bit observed of all cellular cells of self-virtualizing active set always of UE.This virtual active set can be that path loss, Ec/Io to this UE etc. is from the set of the B nodes in defined threshold such as the path loss from this UE to this service cellular cell, Ec/Io.
