Transmission control of a mobile station during E-DCH transmission is uniquely determined, and the operation of a communication system is made efficient. For each of a first physical data channel for transmitting user data transferred from an upper layer through a transport channel to a fixed station and a second physical data channel provided by expanding the first physical data channel, a mobile station has transmission control means for selecting transmission control information including a transmission rate corresponding to the user data, multiplex modulating means for multiplex-modulating the transmission data by using the selected transmission information and the amplitude coefficients of the first and second physical data channels,; and transmission power control means for controlling the transmission power of transmitting means for transmitting the transmission data after amplifying the power to a predetermined transmission power. The transmission control means judges whether or not the transmission power of when the control channel for transferring the control data of the second physical data channel is not transmitted exceeds a maximum transmission power value and selects transmission control information on the first physical data channel.

Description

Mobile radio station and communication means
Technical field
The present invention relates to that a kind of (Code Division Multiple Access: code division multiple access) mobile radio station of implementing in the mobile communication system of mode (mobile station) and communication means relate in particular to having set in up link and send mobile radio station and the communication means of implementing in the mobile body communication system of channel of HRPD (high rate packet data) (packet data) having used CDMA.
Background technology
In recent years, as high speed CDMA mobile communicating mode, International Telecommunication Union adopts a plurality of communication standards be called for the 3rd generation as IMT-2000, has begun commercial service in calendar year 2001 in Japan about one of them W-CDMA (FDD:Frequency Division Duplex (Frequency Division Duplexing (FDD))).The W-CDMA mode is by 3GPP (the 3rd.GenerationPartnership Project: third generation partner program), determine 1999 editions (the Version names: 3.x.x) as initial specification of version that gathered with 1999 as standardisation bodies.Current, as the new edition of version 1999, stipulated edition 4 and version 5, and, during version 6 is being studied, is being made.
Below, simple declaration relates to the main channel of the specification before the version 5.Dedicated Physical Control Channel) and DPDCH (DedicatedPhysical Data CHannel: Dedicated Physical Data Channel) as the physical layer channel of distributing to mobile radio station separately of version 1999 correspondences, DPCCH (DedicatedPhysical Control CHannel: is arranged.The transmission that DPCCH is used for the various control informations (using pilot signal, transmitting power control signal etc. synchronously) of physical layer receives.DPDCH is used for receiving from the transmission of the various data of MAC layer (Media Access Control, the upper-layer protocol layer of physical layer).Incidentally, the channel that will be used for the exchanges data of MAC layer and physical layer is called transmission channel (Transport channel).In version 1999, will be called DCH (Dedicated Channel: dedicated channel), can set a plurality of corresponding to transmission channel as the DPDCH of physical layer channel.In addition, up link and down link both sides are set above-mentioned DPCCH and DPDCH.
In version 5, the efficient that sends for the grouping that realizes in the down link improves, import HSDPA (High Speed Downlink Packet Access: high-speed downlink packet inserts) technology, as the physical layer channel that down link is used, append HS-PDSCH (High Speed-PhysicalDownlink Shared CHannel: High-Speed Physical Downlink Shared Channel) with HS-SCCH (High Speed-Shared Control CHannel: High-Speed Shared Control Channel).HS-PDSCH and HS-SCCH use at a plurality of mobile radio stations.The DPDCH that HS-PDSCH and version 1999 are corresponding is the same, sends the data from the MAC layer.Control information (modulation system of transmission data, grouped data amount etc.) when HS-SCCH is sent in by HS-PDSCH transmission data.
The invasin of HS-PDSCH (spreading factor) is fixed as 16, can distribute a plurality of spreading codes (spread code) (a plurality of channel) to 1 mobile radio station when once grouping sends.Stipulate under the 3GPP standard this distribution control (so-called scheduling (scheduling)) in the base station (being the fixed station side in the general communication system) carry out.In addition, in version 5,, append HS-DPCCH (High Speed-Dedicated Physical Control CHannel: High-Speed Dedicated Physical Control Channel) as the physical layer channel that up link is used.Mobile radio station uses HS-DPCCH, will send to the base station to the reception result of determination (ACK/NACK) and the downlink wireless quality information (CQI:ChannelQuality Indicator (CQI)) of the data that sent by HS-PDSCH.
The base station sends HS-PDSCH and HS-SCCH in pairs.Whether mobile radio station receives HS-PDSCH and the HS-SCCH that sends from the base station, wrong in the decision data, uses HS-DPCCH to send result of determination (ACK/NACK).Therefore, change corresponding to the transmission frequency of the grouping of down link to the frequency that the base station sends ACK/NACK from mobile radio station.In addition, mobile radio station sends to the base station according to setting (configuration) by the fixed station side and be notified to the periodic quantity of mobile radio station in communication starting stage or communication with CQI.
When using DPDCH to send data, the information embarkation of the data volume (communication speed) of the multichannel multiplexing method of the data of 1 above DCH or time per unit is sent on DPCCH, be notified to receiver side.The announcement information that will comprise " multichannel multiplexing methods of data " or " data volume " is called TFC (Transport Format Combination: transformat combination), send the TFCI (TFC Index) as the index of TFC.When determining communication speed, determine the channel amplitude coefficient (channel gain factors: β d) of the transmitted power of regulation DPDCH by TFC.The TFC integral body that obtains during with transmission is called TFCS (TFC Set: transport format combination set), in the initial setting stage or communication of communication, set between mobile radio station and fixed station.In addition, to each TFC, specified states changes (Support, Excess Power, Block), reflect transmit status, determine the state (and state-transition) of TFC, this is regulation in standard book TS25.321 (non-patent literature 1:11.4 chapter Transportformat combination selection in UE, Fifure 11.4.1).Promptly, reach the quantity of the unit transmitting time (slot:10 millisecond 1/15) of maximum transmit power setting (or maximum transmit power set point) by total transmission power value (presumed value or measured value) of estimating (Evaluation) mobile radio station, thereby change the state of each TFC among the DPDCH.This point is regulation in standard book TS25.133 (non-patent literature 2:6.4 chapter Transport format combination selection inUE, 6.4.2 chapter Requirements).

The transmission of the continuous data that version 1999 main hypothesis sound conversations are such receives formulates.In version 5, though appended the HSDPA that can carry out the high speed packet communication of down link, do not implement the specification institution of the high speed packet communication of hypothesis up link, former state has been used version 1999 specifications.Therefore, in up link, even if under the situation of transmission from mobile radio station to the base station that carry out the burst (Burst) as grouped data from, also must distribute special-purpose individual channel (DCH and DPDCH) to each mobile radio station all the time, if consideration is by the situation of the grouped data transmission demand raising of the universal up direction that causes of internet, then from the viewpoint of effective utilization of Radio Resource, existing problems.
In addition, the data from mobile radio station send self-disciplining transmission control (the Autonomous Transmission: autonomous transmission) carry out that utilizes mobile radio station.At this moment, regularly be (or being at random on the statistics) arbitrarily from the transmission of each mobile radio station.Carry out self-disciplining at mobile radio station and send control, carry out in the system of data transmission, the fixed station side is indifferent to the transmission timing of mobile radio station.In the communication system of having used the cdma communication mode, though the transmission from other mobile radio station all constitutes interference source, but, with regard to the reception of base station, only can predict (or management) interference noise amount and variation thereof carrying out the fixed station side of RRM with adding up.Like this, the fixed station side of managing radio resources in the communication system of using the cdma communication mode, owing to be indifferent to the transmission timing of mobile radio station, and, correct predicted interference noisiness, so suppose the situation that the variation of interference noise is big, fully guarantee the allocation of radio resources control that nargin is such.The RRM of this fixed station side is not that itself carries out in the base station, but carries out in gathering the base-station control apparatus of a plurality of base stations (RNC:Radio Network Controller (radio network controller)).
RRM that base-station control apparatus (RNC) carries out mobile radio station or the notice of following it need the long processing time (several 100 milliseconds of grades).Therefore, can not be adapted to the allocation of radio resources control of the suitable up link of the rapid variation of wireless propagation environment or the transmission situation of other mobile radio station interference volume of other mobile radio station (=from) etc.Therefore, for the effective utilization that realizes Radio Resource and allocation of radio resources at a high speed, in version 6, import E-DCH (EnhancedDCH: technology enhancement type special channel), stipulate detailed specification.The E-DCH technology is also referred to as HSUPA (High Speed Uplink Packet Access: high speed uplink packet inserts).In the E-DCH technology, the AMC that can in version 5, import at HSDPA (AdaptiveModulation and Coding: adaptive modulation and coding) technology, HARQ (HybridAutomatic Repeat reQuest: mix automatically retransmitting) technology etc., use short transmitting time interval (TTI:Transmission Time Interval (Transmission Time Interval)).In addition, E-DCH is meant the transmission channel of expansion as the DCH of the transmission channel of existing standard, independently sets with DCH.
In E-DCH,, be called the Radio Resource control of the up link of " scheduling " in the fixed station side.Because radio propagation environment etc. is different in up link and the down link, so different with the scheduling of HSDPA.Mobile radio station carries out the transmission control of data according to the scheduling result from the fixed station notice.Fixed station will send to mobile radio station to the result of determination (ACK/NACK) of the data that receive.Regulation base station (being called node B in 3GPP) is as the device of dispatching in the fixed station.With regard to the concrete grammar example of the scheduling of using with regard to E-DCH in the base station, Japanese Patent Application Publication 2004-215276 communique (patent documentation 1) is for example arranged.In addition, the 3GPP standard book that makes as being used for E-DCH (Technical Specification: technical specification), TS25.309v6.3.0 (non-patent literature 3) is arranged.

Reinforced Dedicated Physical Data Channel) and E-DPCCH (Enhanced-DPCCH: reinforced Dedicated Physical Control Channel) in version 6, the physical channel of the up link of using as E-DCH appends E-DPDCH (Enhanced-DPDCH:.E-DPDCH and E-DPCCH are equivalent to DPDCH before the version 5 and the physical channel of DPCCH, and E-DPDCH sends the data from the MAC layer, and E-DPCCH sends control information.In addition, the TFC that uses with DPDCH is the same, uses the E-TFC (Enhanced-TFC) of regulation communication speed.According to communication speed, determine the gain factor (β ed) of E-DPDCH.In addition, in version 6, the enhancement mode absolute grant channel), E-RGCH (Enhanced-Relative Grant CHannel: enhancement mode relative authorization channel), notice receives the E-HICH (E-DCH HARQAcknowledgement Indicator CHannel: confirm indicating channel) of result of determination (ACK/NACK) physical channel of the down link of using as E-DCH appends E-AGCH (the Enhanced-Absolute Grant CHannel: of notice scheduling result.
When the data from mobile radio station send, E-DCH and DCH are handled as independent data stream (Data Stream), in addition, determine that the DCH transmission has precedence over E-DCH and sends.Like this, because E-DCH is and the DCH independent data stream, and, DCH sends and has precedence over the E-DCH transmission, so mobile radio station is guaranteed DCH and is sent required transmitted power, selects E-TFC in remaining transmitted power nargin (power margin), carries out the transmission of E-DCH.In above-mentioned non-patent literature 3, the same with TFC, to E-TFC definition status (blocked state (blocked state) or supported state (status of support)).
Summary of the invention
The problem that invention will solve
Below, the problem that relates to because of the transmission control of appending the up link that E-DCH produces is described.According to non-patent literature 3 (TS25.309),, determine the communication speed (E-TFC) when E-DCH sends according to the nargin power of guaranteeing from maximum total transmitted power of mobile radio station after DCH sends required power (transmitted power nargin).In addition, according to the nargin of transmitted power, make the state-transition of E-TFC.But owing to do not stipulate the detailed benchmark of the state-transition of E-TFC, the interior mobile radio station transformation work of communication system is not unique, the job insecurity and the not high problem of efficient of communication system so exist.And then the definite benchmark of the E-TFC when E-DCH sends is also indeterminate.Like this, because the detail specifications in the E-TFC deterministic process is unclear, so there is the problem that to make actual device.

Also can replace formula (4), according to the practical structures of the transmitting channel after multiplexed, be that the power offset information etc. of other channel of benchmark is obtained by always send average power information (UE transmit power), (2) E-TFC, (3) β ed information, (4) DPCCH with (1).Perhaps, omit step 402b, directly obtain total transmitted power nargin (Pmargin) and also can.Above-mentioned formula (4) is the formula when carrying out the true value subtraction.
Then, in the step 803 of Fig. 8, estimate the state of the E-TFC that uses in sending, restriction (E-TFC Restriction) spendable E-TFC.Transmit setting evaluation portion 203 and give transmission speed restrictions 204 (step 803) the state information notification of each E-TFC.For example, any one of as the state information of E-TFC, can notify " state " of certain E-TFC to be " can not use (blocked) " and " can use (supported) " also can be notified the E-TFC that can use (supported).
Figure 10 is the state of explanation evaluation E-TFC and the flow chart that limits the processing of spendable E-TFC.Figure 10 illustrates the details of the step 803 of Fig. 8.At first, transmit the past of appointment in setting evaluation portion 203 basises of calculation or current middle pairing gain factor of E-TFC (β ed) that uses of transmission timing (=time slot).And then, according to the power offset information of gain factor (β ed) with HARQ profile, obtain channel amplitude coefficient (gain factor gain factor (the β ed of effective E-DPDCH, eff), corresponding to the E-TFC that uses, infer and send required E-DPDCH channel power (step 803a) originally.Then, confirm whether the E-DPDCH channel power of inferring surpasses the total transmitted power nargin (Pmargin) (being whether transmitted power does not have nargin) (step 803b) in the above-mentioned transmission regularly.Be to be under the situation of (promptly surpassing under the situation of total transmitted power nargin (Pmargin)) in step 803b, move to step 803c, internal counter (not shown) corresponding to this E-TFC is increased, in step 803b,, move to step 803g (step 803b) under the situation not.Afterwards, after step 803c handles,, estimate the state (step 803c, 803d) of each E-TFC according to timeslot number of stipulating in the standard (or counter number) and state-transition condition.Then, the state information of E-TFC or the group of spendable E-TFC (E-TFC subset) are outputed to transmission speed control part 204 (step 803e).Afterwards, confirm whether the E-DCH transmission finishes (being that E-DCH sets end).Under the situation that is (being the non-transmission of E-DCH), the end process flow process under the situation of denying, moves to step 803a (step 803f).
Step 803b for situation not under, in step 803g, confirm in the past or E-TFC that current transmission is regularly used in (=time slot) in, whether total transmitted power of mobile radio station reach maximum total transmitted power (Pmax).In step 803g,, move to step 803h, under the situation of denying, move to step 803d (step 803g) under the situation that is.In step 803h, confirm when E-DPCCH sends, carry out the independent channel power compression of E-DPDCH channel, whether be non-transmission (DTX:Discontinuous Transmission (discontinuous transmission)).Under the situation that is (being DTX), corresponding counter is increased.Under the situation of denying, move to step 803d, counter is increased, be not reflected in the E-TFC restriction processing.
As mentioned above, when the E-TFC restriction of carrying out the step 803 that illustrates with Figure 10 was handled, then then execution in step 804 confirmed whether the transmission of E-DCH finishes.Sending (step 804 is for denying) under the uncompleted situation, turn back to step 801.Under situation about being sent completely (step 804 is for being), process ends.
As mentioned above, mobile radio station carries out E-TFC and selects to handle in the transmitting time interval of each regulation (TTI), estimates, selects to use which E-TFC.This evaluation use the transmitted power nargin of inferring (be beyond the E-DPDCH channel infer total transmitted power and maximum total transmitted power (Pmax)), the whole E-TFC that comprise among the E-TFCS are carried out.In the minute interval, do not send under the situation of HS-DPCCH, the transmitted power nargin of certain E-TFC is inferred use TFC/E-TFC, gain factor and the benchmark transmitted power of each channel (DPDCH, DPCCH, E-DPDCH, E-DPCCH) to carry out.Here, so-called transmitting time interval is the 1TTI that 1 time slot for example being determined by the slot timing of DCH (DPDCH/DPCCH) or E-DCH send.In addition, so-called benchmark transmitted power is that certain transmitted power nargin is used when inferring, the transmitted power of each channel in the particular assay time interval.On the other hand, in the minute interval, in partly or entirely, send under the situation of HS-DPCCH, the transmitted power nargin of certain E-TFC is inferred the maximum and the benchmark transmitted power of the gain factor of the HS-DPCCH of use in the TFC (E-TFC) that uses each channel (DPDCH, DPCCH, E-DPDCH, E-DPCCH) and gain factor, the minute interval and carry out.
For the channel beyond the DPCCH, also can use with the DPCCH channel power to replace gain factor as the power offset of benchmark.In addition, in the above-described embodiment, E-DPDCH whether non-transmission (DTX) is separately considered in E-TFC restriction, but can be considered that also the independent channel power of E-DPDCH cuts down (being that gain factor is cut down).With regard to the execution mode of this moment, execution mode 3 described later is described.And then, in the present embodiment, only past or current middle E-TFC that uses of transmission timing (=time slot) were inferred originally essential E-DPDCH channel power (step 803a), but also can infer originally essential E-DPDCH channel power, determined the state of each E-TFC whole E-TFC.
The work disposal of transmission speed control part 204 shown in Figure 8, modulation portion 205, sending part 206 is described.At first, transmission speed control part 204 is the same with Fig. 8 (a), and whether investigation is set with E-DCH and sends (step 805).Then, whether confirm to set the arrived lastest imformation of E-TFC state of evaluation portion 204 from transmitting, under situation about arriving, update mode (step 806).Then, as known in the art, according to the scheduling result information of taking out from the E-AGCH that receives and E-RGCH, the value of the variable (Serving_Grant) that the inner setting of renewal mobile radio station is used, according to this built-in variable and E-TFC state information, select the E-TFC (step 807) that uses in (TTI) between 1 next sending area.As the method for selecting, there are (1) strict application built-in variable and E-TFC state information to select so that become the method for the E-DPDCH channel power (ratio) in the allowed band; (2) the E-TFC state is for example got the method for setting after the average correction of nargin again of several TTI in the past though the built-in variable strictness is used; (3) except that built-in variable and E-TFC state information, also consider the method that transmission power control instructs the accumulated value of (TPC) to select; (4) allow the method etc. of the temporary transient selection that surpasses built-in variable, carry out according to the installation or the standard code of mobile radio station.
Figure 11 is that explanation E-TFC selects to handle the flow chart of (E-TFC selection).Figure 11 illustrates the details of the step 807 of Fig. 8.In Figure 11, at first, be confirmed to be first transmission and still transmit data once more.Under the situation of first transmission the (being that step 807a is for being), move to step 807b.In addition, under the situation that transmits (being that step 807a is for denying) once more, move to step 807d (step 807a).Under first situation about transmitting, in the restriction of total transmitted power nargin, select spendable E-TFC (step 807b).As the E-TFC system of selection among the step 807b, (1) high transmitting more at a high speed of QoS setting medium priority to each multiplexed MAC-d stream of E-DCH can be arranged; What (2) priority of channel that uses in the upper-layer protocol or data was high transmits more at a high speed.Use the installation specification regulation of which method by standard book or communication system.Then, according to the E-TFC that selects among the step 807b, calculate the actual gain factor-beta ed of E-DPDCH, eff afterwards, with E-TFC information, outputs to transmit and sets evaluation portion 203 and modulation portion 205.At this moment, under the situation that also sends other channel, also export the gain factor (step 807c) of other channel.On the other hand, in step 807a,, do not carry out E-TFC and select to handle, move to step 807c (step 807d) under the situation that transmits (being that step 807a is for denying) once more.Afterwards, move to the step 808 of Fig. 8.
Then, carry out the transmission of E-DCH by E-DPDCH, E-DPCCH.Modulation portion 204 is determined the relative power ratio of interchannel according to the gain factor of each transmitting channel (E-DPDCH, E-DPCCH), utilizes known technology, multiplexed and each channel of modulation.Afterwards, modulation signal carries out frequency inverted, power amplification, sends from antenna 207.Send the details of handling and send processing (step 808) as described later with DCH.Then, in the step 809 of Fig. 8, confirm whether the E-DCH transmission finishes, under the situation that is (promptly finishing), finish to send handling process.Under the situation of denying, move to step 805, repeat above-mentioned steps.
Figure 12 is the flow chart that the transmission power control of explanation mobile radio station is handled.Figure 12 illustrates the details of the step 407 of Fig. 4.At first, transmitted power is measured gain factor and the closed loop transmission power control instruction (TPC) of control part 208 according to the channel of reality transmission, infers next transmission timing (time slot or TTI) and sends required total transmitted power (Estimated UE transmit power).Afterwards, transmitted power is measured control part 208 investigation and whether is inferred total transmitted power (Estimated UE transmitpower) above maximum transmit power set point Pmax (step 407a).Do not surpassing under the situation of Pmax (promptly denying), transmitted power is measured control part 208 to sending part 206 output transmission power control information (Po_cont), and the transmission of execution in step 407i is handled.Surpassing under the situation of Pmax (promptly being), move to step 407b.Afterwards, transmitted power is measured the treatment step of control part 208 by step 407b, 407c1,407c2,407d1,407d2,407e1,407e2,407f1,407f2, only reduces the gain factor β ed of E-DPDCH, the value of eff, and total transmitted power diminishes.For example, at this moment, under the situation of setting DPDCH (being that step 407b is under the situation that is), β ed, eff can the reduction value to zero (being DTX work), do not setting under the situation of DPDCH (be step 407b for situation not under), can be reduced to assurance minimum value (the β ed of notice mobile radio station, eff, min).Because gain factor β ed, eff gets quantized discrete programing value, so the gain factor that reduces in step 407c1 or 407c2 is under the situation of median of discrete programing value, is set at little centrifugal pump.Utilize above the processing, near maximum transmit power set point Pmax.
Transmitted power is measured control part 208 to modulation portion 205 output gain factor control signals (β _ cont), revise the final gain factor set point of E-DPDCH.In addition, transmitted power is measured control part 208 to sending part 205 output transmission power control information (Po_cont).Then, in step 407g, transmitted power mensuration control part 208 is investigated once more and whether is inferred total transmitted power above maximum transmit power set point Pmax.Under the situation of (being that step 407g is for denying) under the situation about not surpassing, move to step 407i, and (Po_cont) outputs to sending part 205 with control information.On the other hand, under the situation that surpasses Pmax (step 407g is for being), move to step 407h, keep comparing of each channel transmission power constant, append channel transmission power compression control (Additional scaling or Equal scaling), total transmitted power is accommodated among the Pmax.Afterwards, after this power compression of appending control of reflection, transmission power control information (Po_cont) is outputed to sending part 206, and move to step 407i (step 407g).
Then, sending part 206 amplifies modulation signal (Mod_signal) according to the control information (Po_cont) of input, exports as wireless signal (RF_signal).The wireless signal (RF_signal) of output is wirelessly transmitted to base station 103 (step 407i) from antenna 207.Under the situation of the final gain factor vanishing of E-DPDCH,, send E-DPCCH though E-DPDCH is non-transmission.Afterwards, move to the step 408 of Fig. 4.The processing thought of step 407b-507h is stipulated in the standard book.Then, in the step 408 of Fig. 4, whether the transmission of investigation E-DCH regularly (TTI) is 10ms.This is because the TTI of DCH is 10ms sometimes, and the TTI of E-DCH is 2ms.At the TTI of E-DCH is under the situation of 2ms, owing to send the TTI end of E-DCH in the way at DCH, so move to step 404, repeats to control.
Then, whether each transmission of confirming DCH and E-DCH finishes (or set and remove).Under the situation that sends under the uncompleted situation, promptly denys, return step 405.Under the situation about being sent completely, under the situation that promptly is, process ends (Fig. 4, step 409).Have, handling process that E-TFC estimates and the TFC of DCH estimate independent process again.Thus, can guarantee back compatible (Backwardcompatibility), and make the transmission control of mobile radio station become simple.In addition, in the transmission speed control part 203, E-TFC selects to select independent process with the TFC of DCH.Thus, setting evaluation portion 202 is the same with transmitting, and can guarantee back compatible (Backward compatibility), and makes the transmission control of mobile radio station become simple.The concrete work of estimating as the TFC of DCH is carried out according to the standard of maximum transmit power setting like that as the prior art regulation.
Figure 13, Figure 14, Figure 15 be schematically show be used to illustrate maximum total transmitted power (Pmax) regulation of mobile radio station, the transmitted power of each channel and the key diagram of transmitted power nargin.Below, Pmax set point and benchmark of using in the inferring of transmitted power nargin (or calculating) are described.In Figure 13, Figure 14, Figure 15, Pmax (Capability or NW) expression can be used as mobile radio station ability (UEcapability) output maximum transmit power or set from the maximum transmit power of Radio Resource control part 301 notices of fixed station.Mobile radio station can not send with the total transmitted power that surpasses this value in this work.Pmax (β d, β c) sends as HSDPA to stipulate with the Pmax under the situation of the situation of the HS-DPCCH of channel and not setting (or transmission) E-DCH, in standard book TS25.101, sets the low value than above-mentioned Pmax (Capability) for.In addition, Pmax (β d, β c, β hs, β ed (, eff), β ec) be the Pmax regulation when setting (or transmission) E-DCH.In the present embodiment, establish Pmax (Capability or NW) 〉=Pmax (β d, β c) 〉=Pmax (β d, β c, β hs, β ed (, eff), β ec).Have again, Pmax (β d when also sending as HS-DPCCH sometimes, β c) like that, be the regulation of the gain factor that do not rely on this channel, whether comprise the PAR that whole gain factors depends on wireless signal (RF_signal) (Peak to AverageRatio: peak-to-average force ratio) wait definite.In addition, also can be when E-DCH sends with channel set different regulations during with non-the transmission.These various Pmax are set in the standard book and stipulate, or notify from the fixed station side.In standard book, in the standard book, stipulate Pmax (Capability), and the Pmax (β d, β c) of Pmax (Capability or NW) as the version 5 of prior art.In addition, as the definition of Pmax, also can comprise the power offset etc. of the E-DDPCH channel of determining according to HARQ profile, to the power offset of each channel of DPCCH, as parameter.Expressing under the situation that comprises power offset, for example becoming Pmax (β d, β c, β hs, β ed, Δ E-DPDCH, β ec) or Pmax (β c, Δ DPDCH, Δ HS-DPCCH, Δ E-DPCCH, Δ E-DPDCH) etc., under the situation that hint comprises, become Pmax (β d, β c, β hs, β ed, eff, β ec) etc.
Figure 13, Figure 14, Figure 15 also can regard the combination of the channel when sending and the relation of Pmax regulation as.Among the figure, the longitudinal axis is represented transmitted power, and transverse axis is represented the radio wave propagation distance apart from fixed station.The transmitted power of each channel is represented relativeness, rather than the expression absolute size." append channel transmission power compression 1 (Additional scaling1) " among the figure used and appended the zone that channel transmission power compression (Additional scaling) is handled though be illustrated in the state that only sends DPDCH/DPCCH or set HSDPA but do not send under the state of HS-DPCCH.At this moment, (TFC min) sends expression DPDCH, keeps constant with the power ratio of other channel (DPCCH), and total transmitted power is restricted to Pmax (Capability or NW) with minimum transmission speed.
" append channel transmission power compression 2 " (Additional scaling2) uses the zone that (Additional scaling) handled in the channel transmission power compression of appending though be illustrated in the state that sends DPDCH/PCCH/HS-DPCCH or be set with E-DCH but do not send under the state of E-DPDCH/E-DPCCH.Owing to send HS-DPCCH, so limit by Pmax (β d, β c).(Additional scaling3) is illustrated under the state that sends DPDCH/DPCCH/HS-DPCCH/E-DPCCH " to append channel transmission power compression 3 ", uses the zone of appending channel transmission power compression (Additional scaling).At this moment, E-DPDCH sends with the transmission speed of being determined by the transmission speed control part, but because gain factor can be reduced to zero, so become non-transmission (DTX).Owing to be set with the E-DCH channel, thus by Pmax (β d, β c, β hs, β ed (, eff), β ec) limits.
Below, the situation of Figure 13 is described.Figure 13 is corresponding to being set with the situation that DCH sends, E-DCH sends and HS-DPCCH sends.The channel limit that sends whole up links on the limit is left under the situation of fixed station, by the known closed loop transmission power control of stipulating in the standard book (so-called TPC control), control mobile radio station transmitted power, with the received power in the reception antenna of guaranteeing fixed station (correctly say so in order to ensure essential error rate essential reception Eb/NO), so, then increase the transmitted power of whole channels more more away from fixed station.Among the regional A in Figure 13, send whole channels, but total transmitted power does not reach arbitrary Pmax value.In area B, the Pmax regulation when reaching E-DCH transmission setting (Pmax (β d, β c, β jhs, β ed (, eff), β ec)).E-DCH sends and has precedence over the DCH transmission.In addition, owing in the scope of transmitted power nargin, send the E-DCH channel,, only reduce the transmitted power of E-DCH with channel along with away from fixed station.E-DCH descends with the transmission speed (E-TFC) that the transmitted power of channel reduces the E-DCH that selects when meaning that E-TFC selects.And then, because the E-DPDCH channel gain factors can be reduced to zero, append channel power compression 3 (Additional scaling3) so use.
When E-TFC selects to handle, select E-TFC to make in its scope that is accommodated in transmitted power nargin, do not take place so append the channel power compression work ideally.But because according to the presuming method of transmitted power nargin, the state when E-TFC selects and actual state when sending beginning might be different because of the influence of measuring delay etc., at this moment, also will append the channel power compression work.On the other hand, during the TTI time interval, owing to carry out the transmission power control (so-called TPC control) of time slot unit,, take place on the channel transmission power contraction principle that appends so necessary total transmitted power might surpass the maximum transmit power setting of mobile radio station.But, as illustrating among the step 407g of Figure 12, before appending the channel power compression, only compress the channel transmission power of E-DPDCH.The data etc. of whether appending the channel power compression work or not appending channel compression are determined to be set by the fixed station side, utilize RRC signaling untill further notice mobile radio station, and the work of control mobile radio station also can.
In zone C, send E-DCH channel in addition.In this zone because only by E-DCH with beyond channel, total transmitted power reaches the Pmax regulation, and (Pmax (β d, β c, β hs, β ed (, eff), β ec)) sends the nargin of E-DCH with channel so have.In addition, owing to send HS-DPCCH, so as Pmax, by Pmax (β d, the β c) restriction lower than Pmax (Capability or NW).Because (TFC min), so work as when arriving Pmax (β d, β c), then uses and appends channel power compression work 2 (Additional scaling2) to be set with minimum speed among the DCH.Region D is to send the zone that E-DCH uses channel in addition and do not send HS-DPCCH.In this zone,,, use Pmax (Capability or NW) as the Pmax regulation owing to do not send HS-DPCCH.To DCH be set with minimum speed (TFC, min), so when reaching Pmax (Capability or NW), then use and append channel power compression work 1 (the Additional scaling1 among the figure).
Send the transmitted power margin value that (being E-DPCDCH) sends usefulness as the E-DCH data, inferring (calculatings) is to stipulate any one, deduct the value of the aggregate power of having removed the channel (DPDCH/DPCCH/HS-DPCCH/E-DPCCH) behind the E-DPDCH channel power from above-mentioned Pmax.Pmax (Pmax (β d when being set with E-DCH, β c, β hs, β ed (, eff), the regulation of value β ec)) (setting), consider several different methods, the same as (1) with existing standard, the transmission power control (TPC) of consideration 1dB stride, and define with the 1dB precision equally, (2) characteristic of the wireless signal waveforms such as PAR (Peak to Average Ratio) characteristic that rely on by channel architecture of reflection, with the precision definition littler than 1dB, whether (3) by setting E-DCH, use existing precision or thin precision etc. respectively, regulation or when communication setting (configureation), specify in standard.
Have again, stipulated E-DPDCH channel amplitude (gain factor β ed (, eff) the bigger value of value of the desirable channel amplitude of) value (gain factor β d) than DPDCH.At this moment, the characteristic of E-DPDCH signal waveform plays dominating role, and PAR (Peak to Average Ratio) characteristic is compared with the structure situation that only is existing channel, might be diminished.Therefore, in the regulation of reality, sometimes Pmax (β d, β c, β hs, β ed (, eff), β ec) is bigger than other Pmax setting.Among Figure 13, constitute E-DCH with transmitted power nargin infer benchmark Pmax (β d, β c, β hs, β ed (, eff), β ec) represents certain value, but also can distinguish a plurality of zones or a plurality of condition enactment becomes different value.
Below, the situation of Figure 14 is described, the mark among the figure is the same with above-mentioned Figure 13 with term.Figure 14 is corresponding to setting the situation that E-DCH sends and HS-DPCCH sends, DCH sends non-setting.Be with Figure 13 difference, because the non-setting of DPDCH (non-transmission), so the gain factor of E-DPDCH is set assurance minimum value (β ed, eff, min), appending in the channel compression 3 in the area B, the relative power of maintenance and other channel also compresses E-DPDCH than constant.
Below, the situation of Figure 15 is described.Mark among the figure is the same with above-mentioned Figure 13 and Figure 14 with term.Among Figure 15, corresponding to setting the situation that DCH sends and HS-DPCCH sends, E-DCH sends non-setting (non-transmission).This is setting same as the prior art.Be with Figure 13 and Figure 14 difference, because the non-setting of E-DCH (non-transmission), so the channel that appends that does not produce in the area B compresses 3 (the Additional scalling3 among the figure).The Pmax regulation that the transmitted power nargin that DCH uses is inferred usefulness sends according to HS-DPCCH and has or not, and selects from Pmax (Capability or NW) or Pmax (β d, β c).
With Figure 16 the Pmax that relates to execution mode 1 (β d, β c, β hs, β ed (, eff), β ec) setting are described.Among Figure 16, replace using gain factor directly to stipulate Pmax, but by according to the minimal diffusion coefficient (SF min) of the E-DPDCH of the on/off of the transmission of each channel such as DPCCH, HS-DPCCH, DPDCH, E-DPCCH, E-DPDCH, setting and the transmitting channel quantity arranged side by side (Ncodes) of E-DPDCH, regulation is stipulated maximum reduction rate (the MPR:Maximum Power Reduction) amount of (Pmax (Capability)) from mobile function power, thereby stipulate Pmax (β d equivalently, β c, β hs, β ed (, eff), β ec).Like this, on/off by in the regulation parameter, comprising transmission but not the gain factor of channel, just has following effect, needn't consider to depend on the huge combination of each gain factor combination that a plurality of settings exist, it is easy that mobile radio station sends the control transfiguration, and, the structure of mobile station apparatus is become simple diminishes and can wait as storage area.In addition, owing to before the calculated gains factor, just distinguish whether send,, has the low effect that gets final product of disposal ability of sending controling circuit so transmission power control can be begun as early as possible.
As mentioned above, in the present embodiment, the transmission speed selection of regulation when appending the E-DCH channel etc. send the control details and to existing channel influence reduction method etc., so have the effect that the work unique, that can make communication system of the transmission Control work of mobile radio station is raised the efficiency.
In the present embodiment, show the margin value of total transmitted power by the dimension of power (or power ratio), but the Notification Method from the scheduling result of fixed station is being that (1) gain factor (dB or true value performance), (2) gain factor are than (β ed/ β c, β ed, the performance of eff/ β c etc. or dB or true value), under the situation of (3) power ratio (dB or true value performance), transmitted power nargin also can be stipulated by same performance.Thus, existing when evaluation E-TFC state needn't be in conjunction with dimension, effect that the control of mobile radio station is become simple.
As transmitting time timing or time interval in the setting evaluation portion 203, regulation transmitted power nargin, the margin value of the last time slot of (1) actual TTI that sends TTI is before arranged; (2) margin value in the whole time slots of the TTI before the actual TTI that sends is average; (3) margin value in several time slots before the actual TTI that sends is average; (4) considered presumed value in the initial time slot closed loop transmission power control, the actual TTI that sends; (5) considered presumed value etc. in several time slots closed loop transmission power control, the actual TTI that sends.Under the situation of above-mentioned (1), because the state of the transmitted power nargin before can considering to send, so can more effectively use the Radio Resource of up link.Under the situation of above-mentioned (2), the average work of removing the change in the TTI becomes possibility, in the E-TFC of each TTI selects, can select unsuitable E-TFC when the instantaneous change of time slot unit.In addition, under the situation of above-mentioned (3), can change change E-TFC state by the change between longer-term, the propagation loss that for example causes apart from the variable in distance of base station etc.In addition, under the situation of above-mentioned (4) or (5),, can consider change tendency from now on, carry out E-TFC evaluation and E-TFC and select, use the Radio Resource of up link effectively by considering the closed loop transmission power control.As above-mentioned time slot, (DPDCH, slot timing DPCCH) meets benchmark can to make the DCH of up link.Equally, also (DPDCH, the timing of the TTI of slot timing DPCCH) is carried out to meet DCH in the renewal of E-TFC.As the equalization method, (1) arithmetic average, (2) weighted average, (3) geometric average etc. are arranged, in the installation of mobile radio station, select, or in standard, stipulate.
Execution mode 2.
With Figure 17 the Pmax that relates to embodiment of the present invention 2 (β d, β c, β hs, β ed (, eff), β ec) setting are described.Among Figure 17, by according to the on/off of the transmission of each channel such as DPCCH, HS-DPCCH, DPDCH, E-DPCCH, E-DPDCH with as the categorised regulation (Category) of the E-DCH of mobile radio station ability, be minimal diffusion coefficient (SF min) and maximum E-DPDCH quantity forwarded (Ncodes) side by side, regulation is stipulated maximum reduction rate (the MPR:Maximum Power Reduction) amount of (Pmax (Capability)) from mobile function power, thereby stipulate Pmax (β d of equal valuely, β c, β hs, β ed (, eff), β ec).That is,, comprise mobile function power, but not the channel that each TTI changes sends condition as parameter.Like this, by the categorised regulation (Category) of E-DCH is stipulated as parameter, has following effect, needn't consider to depend on the huge combination of each gain factor combination that a plurality of settings exist, it is easy that mobile radio station sends the control transfiguration, and, the structure of mobile station apparatus is become simple diminishes and can wait as storage area.In addition, the same with Figure 16 of execution mode 1, on/off by comprising transmission in the regulation parameter but not the gain factor of channel, has following effect, needn't consider to depend on the huge combination of each gain factor combination that a plurality of settings exist, it is easy that mobile radio station sends the control transfiguration, and, the structure of mobile station apparatus is become simple diminish and can wait as storage area.In addition, owing to before the calculated gains factor, just distinguish whether send,, has the low effect that gets final product of disposal ability of sending controling circuit so transmission power control can be begun very soon.Gain factor also capable of being combined is as parameter, to replace on/off.As mentioned above, in the present embodiment, because the details of the control of the transmission when having stipulated to append the E-DCH channel, so have the effect that the work unique, that can make communication system of the transmission Control work of mobile radio station is raised the efficiency.Also can make the execution mode and execution mode 1 combination of above-mentioned explanation.
Execution mode 3.
Figure 18 is the flow chart that the state of explanation evaluation E-TFC and the E-TFC restriction that limits spendable E-TFC are handled.Figure 18 further describes the step 803 (E-TFC limits processing) of Fig. 8 of explanation in the execution mode 1, comprises the step common with the flow chart of Figure 10.Therefore, among Figure 18, the step the same with step shown in Figure 10 means identical or suitable processing, so omit explanation.In the present embodiment, in transmission power control step (for example step 407 of Fig. 4 of record in the execution mode 1), under the situation of the channel amplitude that only makes E-DPDCH (β ed) compression (scaling), be reflected in the E-TFC restriction (step 803h1).
